Who is not in the top 5, and why

What they charge

Check any agency yourself in 10 minutes

1. Ask for audited smart contracts on mainnet and who did the audit. Blockchain agencies come and go with the market cycle, so check the company age and filings.
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.
