About
A small team, deep in a few tools rather than familiar with forty.
Data42 was founded in Yerevan in 2021 by engineers who had spent years inside large companies' data platforms and wanted to build them with less overhead and more craft.
Since then we have worked as the embedded data team for a global consumer goods company, delivered brand, influencer, and medical affairs intelligence for a market research firm, and built data and AI products for startups.
Every engagement is run by people who have carried the pager for a platform they built, and the engineer you meet on the first call is the one who writes the code.

Fit
We say no to some work.

- You need twenty engineers by next month.
- You are looking for the cheapest hourly rate.
Everything else, talk to us. The engineer on the first call is the one who writes the code.
