7 Data Lake Consulting Companies for Your Business

Would you like to spend months implementing a data lake in vain? And at the same time risk millions of dollars because of decisions made on incomplete or contradictory data? Of course not. But in practice, this happens often: after launching a data lake, the numbers grow, systems become more complex, the number of reports increases, but this does not simplify decision-making. At some point, it becomes difficult for managers to get a clear picture of what is really happening in the business. And then they start looking for experts who can piece together fragmented information into a coherent picture and restore a sense of control.

In such a situation, Data lake consulting helps to collect data into a single logic, build a clear architecture, and turn the repository into a working tool for business. But is every team capable of transforming Data Lake from a technical project into a business management tool? On the surface, many solutions look the same: the same platforms, similar promises, familiar words about architecture and scaling. But behind this similarity lies a key difference — in approach, experience, and the ability to work with real business scenarios.

To make this task easier for you, we have compiled a list of the best Data Lake consulting companies for whom working with data is a systematic tool. At the end of the article, we have added expert advice on how to hire Data Lake consultants. 

A Brief Comparative Table of Leading Data Lake Consulting Firms

For convenience, let’s start the review with a comparison table. It lists the key advantages of each team and the technology stack they work with. This shows whether the contractor is ready to work with your current architecture and make reasonable changes to it if necessary.

Overview of the 7 Data Lake Consulting Companies

In this section, we will take a detailed look at seven consultancy companies for Data Lake solutions with practical experience in business projects of varying complexity. For each of them, we will highlight their key focus, approach to working with data, and typical scenarios in which their expertise provides the most value. 

Cobit Solutions — Deep Expertise in Data Lake Architecture for Business Solutions

Cobit Solutions is an analytical partner for businesses where the quality of business decisions depends on architecture. The team works with Data Lake on projects where there is already sufficient data, but there is a lack of a comprehensive understanding of what is actually happening in operations and finance. The focus is on architectures that combine different types of data into a single system and allow managers to see the business without distortions and fragmented versions of figures.

A prime example of this approach is our long-standing cooperation with a large retail business operating as an extensive network with numerous points of sale, suppliers, and product flows. For over six years, the team has supported the development of this business’s analytical platform — from basic data centralization to a full-fledged management analytics system that supports daily operational and financial decisions.

As part of this work, Data Lake was used to combine operational, financial, and product data into a single model that evolved alongside the business. The architecture was designed from the outset with scalability, changes in process structure, and further analytics development in mind, allowing the system to be adapted without constant reworking and technical compromises.

Cobit Solutions provides Data Lake consulting services for large-scale businesses that value the practical value of architecture and its performance in real-world conditions.

Indicium — Systematic Data Engineering For Building Reliable Data Lakes

Indicium is a company with a clear engineering focus, for which data lakes begin with data quality and data pipeline stability. The team specializes in data engineering in projects where predictable architecture, change control, and long-term platform reliability are critical.

A prime example of this approach is Indicium’s participation in projects for Snowflake as an official service partner. Within these cases, the team worked on building and optimizing Data Lake and analytical platforms for companies with large amounts of data, focusing on the stability of ingestion processes, manageability of transformations, and scaling the architecture for business growth.

Indicium’s key difference lies in its approach to the analytics platform as an engineering system that must operate without failures in a real environment. This approach makes the team a good choice for businesses that value a reliable foundation for analytics and further development over a quick demonstration of results.

phData — a Modern Data Stack for Quickly Launching Data Lake and Analytics

phData is one of the Data Lake strategy consulting companies that focuses on the rapid transition from scattered data to working analytics. The team works with Modern Data Stack as a holistic system, where architectural solutions are immediately focused on business results rather than long-term technical experiments.

Notable examples include phData projects in the Snowflake, dbt Labs, and Fivetran ecosystems, where the team helped companies build data lakes and analytics platforms with a focus on transparent data transformation and managed data pipelines. In such cases, the key was to reduce the time to first value and create an architecture ready for scaling without a complete overhaul of approaches.

This approach makes phData a relevant choice for businesses that need to quickly launch Data Lake and analytics without sacrificing architecture quality and system manageability.

Thoughtworks — Engineering Data Lake Architectures for Complex And Atypical Scenarios

Thoughtworks is an engineering integrator that approaches Data Lake as a complex software system rather than a standard infrastructure project. The team works with atypical scenarios where data is distributed across many systems, business logic changes rapidly, and ready-made templates do not deliver the desired results.

Thoughtworks’ practical approach is well illustrated by public cases for Netflix and Lloyds Banking Group. As part of these projects, the team participated in building scalable data platforms and complex Data Lake architectures. The key challenges for them were engineering reliability, adapting the architecture to changing business requirements, and working with large amounts of data in distributed environments.

This experience makes Thoughtworks a good choice for businesses that face unusual challenges and need an engineering approach to data lakes.

Lovelytics — Analytical Platforms with Data Lake at the Center of the Ecosystem

Lovelytics is one of the Data Lake consulting firms that focuses on building analytical platforms on top of data warehouses. The team’s focus is on how Data Lake is used further: in the analytical layer, reports, and metrics that the business works with.

Lovelytics’ practical approach is clearly evident in public case studies for Google and clients working with BigQuery. In these projects, the team built analytical platforms around Data Lake with a clear data model and controlled analytical layers. The main focus was on metric consistency and stable analytics performance at scale.

This approach makes Lovelytics a relevant choice for businesses that view Data Lake as the foundation of their analytical ecosystem. The emphasis here is not on data storage itself, but on how it is used in analytics and decision-making.

Onica — Cloud Solutions with a Focus on Security and Scalability

Onica is one of the leading Data Lake consulting firms that gets involved in AWS projects when the stakes are already high. The team works with large, complex, and regulated environments where data comes from dozens of sources and architectural decisions directly impact security, costs, and business stability.

Onica’s most notable cases are related to large-scale AWS projects for enterprise companies. In particular, in collaboration with Autodesk, the team participated in the migration and optimization of the cloud platform, which reduced data processing costs and ensured scalability for hundreds of millions of users. Another notable example is the projects for Shutterfly, where the AWS architecture had to withstand peak loads, large volumes of media data, and strict requirements for access and cost control.

It is this experience with complex, existing environments that sets Onica apart from many other players. Here, solutions are not implemented “by the book,” but are integrated into the company’s real infrastructure so that they work for years, scale with the business, and do not become a source of new risks.

How we selected these companies

We selected consulting teams not based on big names or the number of certifications. The focus was on practical experience working with Data Lake in real business scenarios.

During the selection process, we paid attention to the teams’ ability to work with different data sources, design architectures for specific business tasks, and take into account the further development of analytics. An important criterion was also working with complex environments, where it is necessary not only to implement new solutions but also to integrate them into the existing infrastructure.

We separately evaluated the approach to Data Lake as a long-term management tool rather than a one-time technical project. That is why the list includes teams that combine architectural thinking, technical expertise, and an understanding of the business context.

How to Choose a Data Lake Consulting Partner

Choosing the right partner for Data Lake can determine the success of the entire analytical strategy of the company. After all, the question of how to hire Data Lake consultants is not only about finding specialists with the appropriate technical skills. It also involves choosing partners who can ensure long-term architectural reliability, process transparency, and real business value from working with data.

To make the right choice, follow these recommendations:

• Evaluate the experience of potential contractors in your industry. Your partner should understand the specifics of your business — from finance to manufacturing or e-commerce.
• Check their portfolio and case studies. Real-life examples of Data Lake implementation will show whether the team is capable of working with large amounts of data and complex environments.
• Pay attention to technology partnerships. Certifications and official statuses (AWS, Snowflake, DBT, Power BI) confirm competence and access to the latest practices.
• Evaluate the approach to architecture. A reliable consultant builds a Data Lake as a system that will scale with the business, not as a temporary solution.
• Ask about time-to-value. It is important that the first analytics results appear quickly, without months of experimentation.
• Consider the culture of collaboration. Consulting should be transparent: include understandable processes, ensure change control, and provide clear communication with the client’s team. 

Final thoughts

Choosing a consulting team for Data Lake is a decision that affects not only the architecture but also how the business works with data in the long term. This review brings together teams with different approaches: from systematic Data Engineering and rapid launch of Modern Data Stack to complex engineering architectures and building analytical ecosystems around Data Lake.

For some businesses, it is important to get results quickly, while for others, it is important to withstand the scale, complexity, and changing requirements over time. That is why it is worth looking not only at technology, but also at how teams work with real business scenarios, existing systems, and analytics development after launch.

Data Lake is not an end in itself. It is an infrastructure foundation that either starts working for management decisions or turns into another data warehouse. Who you choose as your partner will determine how the system develops.

FAQs

What should you pay attention to in a consulting company’s portfolio?

The types of business scenarios the team has already worked with, the complexity of the environments, and the duration of the projects. It is not the number of cases that matters, but their depth and the repeatability of similar tasks.

Do larger consulting firms deliver better results than boutique agencies?

Not always. Large firms are strong in scale and standardization, while boutique firms are strong in flexibility and deep engagement. The result depends on the suitability of the approach to a specific project, not on the size of the company.

How long should I expect the consulting collaboration to last?

The initial stages usually take from several weeks to several months. For complex Data Lake platforms, the collaboration often transitions into a long-term format with gradual system development.

What questions should I ask during the initial consultation?

Ask about similar experience, approach to working with existing infrastructure, and knowledge transfer plans. It is also important to understand how the team assesses risks and measures project success.

How do leading consulting companies ensure project success?

Through clear architecture, transparent communication, and phased implementation. Documentation, data quality control, and regular verification of compliance with business objectives play a significant role.

How to avoid excessive dependence on a consulting company?

It is worth agreeing in advance on the transfer of knowledge, documentation, and involvement of the internal team. The best scenario is when consulting helps build a system that the business can develop independently.
