AI and ML have gone from pie-in-the-sky notions to essential business drivers. From the recommendation engines on online retail sites, through to predictive analytics in healthcare and finance, AI/ML systems are playing an increasingly important part in the digital transformation that is underway across the US. By 2025, there’s not a strategy in the competitive landscape that does not incorporate some aspect of AI/ML in it.
But for as thrilling as this prospect is, the path from A to B is seldom simple. Companies tend to be naïve about the challenges of going from an idea to production. Challenges around data quality, algorithm complexity, connecting to legacy systems, and compliance risks obstruct the path. These barriers can lead to project delays, cost overruns, and potentially, in the worst case, prevent certain initiatives from ever taking off. Learning about the pitfalls of AI/ML development early on allows companies to circumvent expensive mistakes.
The US market throws in its own complications. Organizations need to meet strict requirements such as HIPAA for healthcare or CCPA for data privacy, and thus merely satisfying performance and scalability requirements just won’t cut it. There is also a growing demand from investors and regulators for more explainable AI, which increases the responsibility to show how choices are arrived at. This makes the road to production a technical and organizational challenge.
In this blog post, we’ll demystify the top obstacles businesses are encountering as they deploy AI/ML today. From data scarcity to the dangers of deploying ignorant machines, ethical challenges, and a short supply of those with AI skills, each section considers why these obstacles emerge and what companies can do to leap over them. And, perhaps most importantly, we’ll demonstrate how organizations can leverage these challenges as opportunities for differentiation and trust with the US market.
And you’ll walk away with a path ahead to be more proactive in anticipating risks and implementing best practices that will see your AI/ML initiatives move confidently beyond the pilot phase into scaling and at-speed revenue-generating systems.
Data has always been the bedrock of every AI/ML system, but it is also partially responsible for some of the most enduring difficulties. Most of the most difficult challenges in AI/ML are those of quality, availability, and management of data. No matter how fancy your algorithms, if you can’t get the data to them, they’re of zero value.
The first problem ultimately boils down to data quality. Real-world datasets may be noisy, incomplete, or even inconsistent. A hospital may maintain patient EHRs possessing out-of-date patient histories, and a store might suffer from redundant or outdated information about clients. Models make inaccurate or biased predictions if they are trained on low-quality data. Equally problematic is data availability. In the US, startups and smaller businesses may not have access to extensive datasets — and can’t compete with tech giants who are able to capture and analyze petabytes of data.
Another challenge is the bias of the training data. If people like us are little represented in datasets, then when the models start to be used more widely, they can perpetuate really pernicious stereotypes or make unfair predictions. For instance, if an AI hiring tool learns from biased historical data, it could end up discriminating against minority groups. For regulated US industries, such bias is not merely unethical — it can be cause for lawsuit and violation of compliance. Representative data is one of the hardest parts of an AI/ML project, especially where training data is scarce or unbalanced.
However, labeled datasets are needed for supervised machine learning, and labeling is costly in terms of both time and money. For large-scale projects, many millions of labeled images, texts, or records might be needed and can cost hundreds of thousands of dollars. The other risk, where labels are inconsistent or inaccurate, is introduced in outsourcing to labeling companies, as they could reduce model performance. Cost, speed, and quality commonly restrict how companies can label data for AI/ML.
The issues are further amplified by data privacy and security. US legislation, such as HIPAA and CCPA, requires stringent guidelines for the collection, storage, and sharing practices of personal data. Any AI/ML systems that are based on sensitive customer data should implement robust protections. But anonymizing or encrypting data can diminish his big-data dream by reducing the richness of the information available, which in turn compromises model tuning. Compliance is a steady act that runs parallel to performance, creating more complexity for developers.
If the data is bad, the whole AI/ML pipeline breaks down. Weak data practices lead to inaccurate predictions, biased outputs, and compliance risks. This is why good US-based organizations are spending millions building data quality programs, data governance frameworks, quality assurance processes, and ethical sourcing mechanisms. By mitigating data issues upfront, organizations can prevent expensive setbacks and create reliable models.
Even with clean data, creating good AI/ML models is hard. In our experience, most of the core AI/ML challenges arise at this phase: decisions in algorithm selection, collection strategy, and evaluation metrics on performance and scalability.
It’s almost never easy to decide on the right algorithm. Different problems require different solutions — linear regression for making predictions, convolutional neural networks for recognizing images, or reinforcement learning for decision-making. Each of these has its own tradeoffs in accuracy, speed, and interpretability. For businesses, the complexity presents confusion and delays, especially if their internal teams don’t have deep machine learning expertise. Make the wrong one, however, and countless man-months of effort will have been wasted and costs inflated for little to no useful output.
Overfitting and under-fitting are two of the most prevalent AI/ML problems while developing an AI agent -or any model in general. Overfitting refers to the phenomenon where a model fits too well on the training data and does not generalize well to new inputs. Underfitting, on the other hand, occurs when a model is too simple to learn the underlying structure of the data. Both of these problems cause low real-world performance. The challenge is that the balance point isn’t immediately known, and often has to be searched for with a number of iterations (cross-validation), e.g., many times using domain-specific knowledge but requiring a large amount of data.
Developing complex AI/ML models is an extremely computationally-intensive operation. Deep learning models can take days or weeks to train when you have large amounts of data. The price of GPU, cloud infra, and electricity adds up very fast here; it is probably the most expensive task in the area of AI/ML development. Many US small to medium-sized enterprises simply cannot afford the infrastructure required for experimentation and scaling of advanced AI projects.
A related challenge is that many AI models are what researchers call “black boxes.” Sophisticated neural networks can make very accurate predictions, but they do not readily explain why the prediction was made. In industries like health care or finance, where you have regulators and other stakeholders who want transparency, you can’t afford this lack of interpretability. In the context of business, there is a tradeoff between seeking accurate models that are too complicated to explain and using simpler but more interpretable ones.
Model development is rarely linear. The team first needs to iterate through various algorithms, hyperparameters, and architectures to get some satisfying results. Every loop costs time, money, and computing power. Without foresight, projects may descend into the costly humdrum of trial and error, ultimately inhibiting both scalability and ROI.
Modeling deficiencies have a way of only revealing themselves deep into deployment, when inaccurate or unilaterally deficient models start to impose business risks. Dealing with these issues early on in the development of AI/ML can help minimize wasted effort, manage costs, and create easier paths from prototypes to production systems.
Creating an AI/ML model in a lab environment is very different than deploying it into real-world systems at scale. Most of the challenges in AI/ML development are encountered here. Enterprises routinely underestimate the difficulties around integration, production reliability, and scaling for enterprise workloads.
Even if a prototype runs smoothly in the lab, traction can be more challenging in the messy world of real-world data. The presence of outliers, missing values, or unanticipated user behavior can lead to underperforming models. This chasm of death between research and production is already one of the most frustrating AI/ML development problems. In order for the model to work consistently post-launch, companies will have to invest in strict testing routines, strong pipeline schemes, and constant monitoring.
The US does not need to build everything from the ground up — it is already operating on complex legacy systems. Very often, being able to incorporate the AI/ML models into these existing infrastructures is a non-trivial and expensive task. Data silos, legacy APIs, and non-uniform formats can hinder smooth integration. The result is not only delays and additional costs, but also, in many cases, that companies have to rewire parts of their infrastructure before they can deploy them.
Scalability is another hurdle. A model that was trained on a data set with thousands of records simply can’t keep up when it’s tested against millions of transactions in a single day. To deal with efficient demand at an enterprise level, companies need to invest in distributed computing, cloud infrastructure, and proper algorithms. These demands not only quickly increase costs, making scalability one of the most resource-heavy hurdles in AI/ML development. Both smaller companies and larger ones might find the infrastructure bill alone to be enough of a barrier.
Things are far from over even after you deploy. AI models deteriorate over time with shifts in data distributions, a phenomenon referred to as “model drift.” Accuracy levels decline in practice without ongoing monitoring and retraining – resulting in sub-optimal user experiences, and potential compliance issues. This means that long-term operational support is an essential consideration in deployment planning.
Production AI systems face a variety of security risks, such as adversarial attacks, where attackers specifically control model inputs to produce wrong outputs. To ensure that every step of the way is secured, solid defenses must be implemented, updates need to be applied regularly, and access controls enforced. Organizations that fail to do this put themselves at risk of financial loss and public embarrassment.
AI/ML is not truly AI/ML until it’s in production. Not foreseeing any of those obstacles about deployment and scalability can result in a loss of investment and opportunities. By confronting these challenges in AI/ML development upfront — with MLOps practices, solid infrastructure planning, and ongoing monitoring — companies can ensure their AI projects aren’t just implemented but thrive at scale.
As AI becomes increasingly integrated into business and society, compliance and ethical questions now stand at the forefront of the discussion. Indeed, many of the most high-profile failures in AI have little to do with technical flaws and more to do with expectations, trust, fairness, and accountability. For U.S. businesses, those are among the top challenges for AI/ML development.

One of the most famous is bias. If a model is trained on data that encodes a biased version of the world, it will certainly make predictions based on that world — and thus amplify its biases. For instance, hiring algorithms might unfairly screen out job candidates from racial and other minority groups — just as health care models might misdiagnose patients from underrepresented populations. These findings aren’t just damaging: They poison the well of public trust. Transparency is another issue. Complex neural networks can often be “black box” systems for which there is no clear explanation of why they made a decision. This opacity exposes companies to legal and reputational risks.
AI/ML systems in the US need to comply with more and more data privacy laws. Policies such as the California Consumer Privacy Act (CCPA) and policies for healthcare like HIPAA contain stringent frameworks around the collection, storage, and usage of personal data. Penalties: Failure to follow this warning can result in serious injury, death, or property damage. The burden of regulation simply adds to the already challenging task of AI/ML growth, forcing a business to find a way through progress and compliance. The patchwork of rules is made even more complicated by the spread of such privacy laws state by state.
Regulators and customers are calling for accountability. Companies must be able to articulate how their AI systems think and make decisions, especially in sensitive sectors like finance, law, and health care. This trend has been accompanied by a rise in attention to explainable AI (XAI) methods, which are aimed at transparency as well as high accuracy. The tradeoff is that more interpretable models can often be less accurate, and that they are not super easy to measure performance. Companies are balancing compliance and trust against raw efficiency.
Ethical AI is more than just complying with the law. Businesses are presumed to be responsible when collecting and using data, designing algorithms, or interacting with users. For instance, an AI lending app could meet financial regulations but still be troubling if it disproportionately denies loans to particular communities. Tackling these larger ethical considerations is one of the most delicate AI/ML development challenges that companies must address right now.
Ignoring ethical and compliance concerns not only courts legal risks — it undercuts the whole point of AI. Users will not embrace systems they don’t trust, and regulators can be eager to punish organizations that take shortcuts. If companies can take a proactive stance in baking fairness, accountability, and compliance into AI/ML projects, they can transform some of these challenges into differentiators and leadership opportunities in the US market.
Every great AI work is the result of a strong team, but building and retaining an AI/ML team is one of the most challenging things in all of AI. In the US, demand for AI/ML specialists is massively exceeding supply, driving up prices and competition for talent.
The number of companies doing AI research has surged, while the population of technical minds capable of supporting them lags behind. There is a particularly dearth of data scientists, machine learning engineers, and AI architects. This skills gap causes organizations to put projects on hold, settle for underqualified professionals, or overspend to gain access to limited resources. For startups, the problem is an especially tricky one as they are often up against tech giants that have deep pockets to entice talent with generous salaries and benefits.
Technology professionals who are proficient with AI/ML are some of the most expensive talent to hire. In the US in 2025, ML engineers will be able to earn between $140,000 – $180,000 per annum, and it can be $200K+ for anyone very senior. Factor in recruiting cost, training, and benefits, and it becomes one of the largest AI/ML development challenges there is. Little Fish at a Disadvantage. Smaller Companies are also placed at a disadvantage by the fact that their salaries cannot compete with established/A-list players such as Google, Microsoft, Amazon, etc., which can make attracting talent and keeping them that much harder.
An AI/ML project would need more than just coders. They require cross-disciplinary working of data engineering, domain expertise, software development, and regulatory compliance. For instance, a healthcare AI system cannot work without clinical input, as well as technical expertise. Organizing this mix of talent is also an unsung challenge in AI/ML development — many companies’ organizations have a hard time figuring out how to form these ideas around collaborative (rather than siloed) cross-disciplinary teams.
Even when organizations do manage to find AI/ML talent, retaining this talent is extremely difficult. There is also a lot of mobility in this field – translators often change employers so as to obtain better pay or new opportunities. On top of that, the technology changes fast. There are no teams that won’t need upskilling to stay current, and the cost and time of this is an investment. Companies that do not put learning and growth first run the risk of being dragged down by competitors with more flexible, nimble teams.
Great data and algorithms are nothing if you don’t have the right people to leverage them. Skills shortages, expensive resources, and specialist knowledge also play their part in delays, over-budget costs, and project failure. But by acknowledging those AI/ML hurdles up front, businesses can work smarter — using approaches such as staff augmentation or partnering with academic institutions and specialized agencies to address the critical holes.
And that’s not even once an AI/ML system is deployed. In reality, one of the largest challenges in AI/ML is happening for day-to-day business operations. Performance monitoring, infrastructure management, and model serving are all important operational duties that require ongoing attention.
AI models are never static. The distribution of the incoming data can change gradually, and as such, the model learnt needs to adapt to this change, described by model drift. For instance, a retail recommendation engine based on pre-pandemic shopping habits may not apply to 2025 consumer behavior. Without watchdogging, such shifts contribute to performance decay, which can soon render the system worthless. Drift detection, retraining models, and updating pipelines are all crucial but onerous activities that organizations frequently underestimate.
But unlike old-fashioned software, machine learning systems need to be constantly retrained to remain powerful. This requires that companies keep their data sets fresh, retrain models frequently, and test new versions before releasing them. The retraining cycle can become simply untenable for US companies with multiple AI systems to govern. These continuous needs make operational maintenance one of the hardest AI/ML development problems.
AI at scale is prohibitively costly to operationalize. It takes serious cloud infrastructure to train large models, determine real-time inference, and store enormous data sets. For enterprise-grade AI systems, monthly compute and storage bills can range in the 6 to 7 figures. It’s the smaller businesses that find it difficult to justify these costs AND still see a positive return on investment. Balancing the tradeoffs between infrastructure spending and performance is one of the never-ending challenges of AI/ML building that every organization confronts.
Mission-critical operations are frequently at the core of AI-powered systems. For example, a model for fraud in banking has to work with very high uptime. Where reliability is paramount, you need efficient monitoring, failover systems, and quick incident response. Downtime has the potential to cause financial repercussions, regulatory fines, and brand damage. “For us, the focus on operational resilience is equally as important as model accuracy.
All of this is possible as organizations deploy ever-increasing AI models. Handling multiple teams, version control, and documentation can easily get out of hand. This is why MLOps—a formal practice that includes machine learning with DevOps techniques—has risen to the forefront. The absence of this reality is an active barrier to scaling, reduces efficiency, and undermines ROI.
AI isn’t just about creating models; it’s ensuring they stay valuable and trustworthy in the long run. Those businesses choosing not to pay for operational pain are those at risk of wasting millions on databases that decay, rather than improve with time. These challenges faced in AI/ML development can be countered with monitoring, retraining, and infrastructure planning to ensure that company investments around AI continue to offer value over time, past the deployment of tech.
The list of obstacles you have in between may feel overwhelming, but the majority of difficulties businesses face during AI/ML development can be eliminated as long as they follow through with proper strategies, tools, and frameworks for their development. By coming at AI not with just a technical project lens but through the prism of business over the long term, businesses can help reduce risk and deliver value.
As so many challenges begin with data, smart governance is critical. Businesses need to set policies on how data is collected, validated, and managed. Automated quality checks, deduplication, and bias detection tools are techniques to obtain cleaner datasets. For US businesses, integrating data governance and privacy compliance, such as HIPAA or CCPA, not only ensures you’re compliant but also increases customer trust. By increasing the strength of data pipelines early on, companies are able to minimize potentially costly mistakes down the line in an AI lifecycle.
MLOps is one of the most successful ways to tackle operational and deployment challenges. It combines machine learning and DevOps to encapsulate best ML practices. Through automated processes, CI/CD, and source control, MLOps allows companies to navigate the challenges of model drift, retraining, and scaling on a futuristic level. For a large and growing number of U.S. companies, implementing MLOps to manage their AI initiatives has transitioned those efforts from experimental pilots to enterprise-ready reality.
The human resource dimension of AI can best be addressed by cooperation. Many of the challenges faced by AI/ML teams are because they work in silos. By creating cross-functional teams comprised of data scientists, domain experts, compliance officers, and engineers, companies can be better equipped to tackle both technical considerations and questions around ethics. It guarantees that models are both accurate and aligned with business goals and legal needs.
For solving ethical problems in AI design, you need to? Bake in fairness and transparency. Enterprises should be using explainable AI frameworks that make the decisions of models more transparent to those who use them. Any such company would need to develop internal review panels or ethics boards that oversee sensitive use cases at the very least. Although these efforts may be laborious, they stave off reputational harm and foster consumer trust in AI.
Not every company has the resources to develop AI capabilities in-house. Joint ventures with specialist suppliers or handoffs to contracted staff can relieve skill shortages without resorting to full-time hires. This has been particularly beneficial in the U.S., where there’s a huge bottleneck problem with a lack of AI/ML professionals. A strategic partnership gives access to the best brains, proven frameworks, and industry exposure. Resource constraints would then matter less.
AI/ML is hard, and it requires a proactive approach to succeed. With solid data governance, adoption of MLOps, an ethical guide, and the right mix of skills in place, organizations can go from failing pilots to scalable, revenue-generating systems. It will be the businesses that view AI as a strategic, not just technical, endeavor that eventually succeed.
