yesfor.ai vs Deloitte

Deloitte in Poland 2026

Deloitte Poland is one of the largest Big4 firms in the country, with offices in Warsaw, Wrocław, Kraków, Poznań and other cities. The technology practice covers strategic consulting, implementation, audit and regulatory advisory. AI and Data Analytics is a dedicated subspecialty within the larger technology practice.

The Deloitte AI Institute publishes regular industry reports and is one of the most frequently cited sources in the global and Polish discourse on AI. That is a good sign: Deloitte is building a position as a thought leader, not just a service provider.

Deloitte's annual public reports (published on deloitte.com) contain data on the scale of the Polish office, its revenue structure and its sector specializations.

What Deloitte does well in AI

Three areas where Deloitte's position in Poland is strong.

Global delivery model. A client with subsidiaries in many countries gets a single team under a single contract, with local consultants in each location. yesfor.ai is fully Polish, with no global network.

Compliance and audit credibility. Deloitte is not only a consultancy, it is also an auditor. For decisions that require a signature on a readiness assessment submitted to a regulator (KNF, UODO), the Big4 brand carries real reputational value. The yesfor.ai brand is new, and its reputational currency will only build over the next 12 to 24 months of references.

Sector specialization. Deloitte Poland has dedicated teams for banking, insurance, energy, retail and the public sector. Each team brings deep knowledge of the regulatory and operational specifics of its industry. yesfor.ai is sector-agnostic and focuses on mid-sized companies of 200 to 3,000 people across different sectors.

What Deloitte does differently (in the smaller-project segment)

Three areas where the Deloitte model is scaled for a different type of client.

Minimum engagement size. Deloitte Poland, like every Big4 firm, calibrates its minimum engagement size to the economics of maintaining multidisciplinary teams. Projects below that threshold sit outside its business model. yesfor.ai works in a range where the Big4 do not operate.

Pyramid team structure. A typical mid-scale Deloitte project is a team with 1 partner (5 to 10 percent of the time), 1 senior manager (15 to 25 percent), 1 manager (full-time) and several junior consultants (full-time). Most of the detailed work is done by consultants in their second or third year out of university. yesfor.ai operates with seniors who have 10+ years of experience for 100 percent of the work.

Independence from technology vendors. Deloitte has strategic partnerships with Microsoft (Azure AI), IBM (watsonx), Oracle, SAP and Salesforce. These partnerships are publicly documented on Deloitte's pages. They generate revenue and influence technology recommendations. yesfor.ai has no partner contracts with AI vendors.

A concrete comparison scenario

Client: a mid-sized Polish industrial manufacturer in the 500 to 2,000 person range, in the manufacturing sector, with a first-year AI budget of a few hundred thousand zloty.

The standard path with Deloitte. An AI readiness audit with a multidisciplinary team, running over several months, with a strategic document as the deliverable. A pilot as a separate contract with a different partner (Deloitte usually recommends a technology partner from its ecosystem).

The standard path with yesfor.ai. An AI readiness audit over a few weeks, a team of one to three people with the founder, an operational report plus concrete quick wins as the deliverable. A pilot implemented by yesfor.ai or by a provider chosen by the client, as the next phase of the project.

The difference is not only about price. It is philosophical: Deloitte delivers a strategic document for further planning, yesfor.ai delivers a working first pilot within 6 months.

Conclusion

Deloitte is not "worse," it is built for a different scale of problem. A Polish manufacturer running its first AI project needs an audit that leads to a working pilot in 6 months, not a multi-page strategic document.

For that client yesfor.ai is the structurally better choice. For a global group with an AI transformation across 20 countries, Deloitte. The decision should rest on the scale of the problem, not on the brand.
