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. React Native lets a web team ship mobile apps, which is its strength and its trap. Ask for apps in the stores you can install today and how they handle the new architecture.
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.
