• The largest public portfolio in the city, with named brands such as Pizza Hut, Merck and Polaroid, and 4.8 on Clutch from 61 reviews.
• Profitable in 2025 (1.2M PLN on 29.3M PLN of revenue) and owned by the founders’ family foundations, so no foreign parent.
• Official Vue and Nuxt partner, with offices in Chicago and Berlin for clients in those markets.

Verdict. The best-known name on this list and the best client reviews by volume, dragged down by what its own people say. Hire it for the portfolio, write the team into the contract.

6

Grape Up

Clutch: 5.0 (6 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

• The site shows no ISO or cloud partner certifications, although Grape Up sells sovereign cloud and AI governance products (source).
• Clutch shows 5.0 from 6 reviews, a $50,000 minimum project, $50 to $99 per hour and 50 to 249 employees (source).

Clients they name: Cummins

All companies in the data set, with the same score. Companies without a confirmed office, sole traders, body-leasing firms and product companies are listed but not ranked.

Who is not in the top 10, and why

What they charge

Check any agency yourself in 10 minutes

1. Poland has a strong Rails community from the 2010s, and several houses still specialize in it. Ask about upgrades across Rails major versions, because that is where old apps get stuck.
2. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
3. Read the last financial statement on rejestr.io: revenue, profit or loss, and whether it was filed on time.
4. Check the VAT white list: active, and the name matches the contract.
5. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
6. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
7. Ask who exactly will work on your project, and check those people on LinkedIn.
