A small Estonian engineering company that takes the platform off your roadmap.
Eighteen platform engineers, smart-contract developers, and SREs. Three offices: Tallinn, Madrid, Lisbon. One promise: ship the infrastructure, document it, and stay on-call until your team doesn't need us.
Blocklyne started in 2021 as a two-person consultancy stitching together Hyperledger Fabric networks for Baltic banks. We kept running into the same problem: the ledger was the easy part — running the surrounding apps to a regulator's standard was where projects went sideways.
Today we're eighteen people delivering two platforms — ChainLaunch and Temps — to financial services, public sector, and platform engineering teams across the EU. We're profitable, founder-owned, and small on purpose. You'll always know the names of the people running your platform.
We are an Estonian e-Residency partner, a Hyperledger Foundation member, and members of the Estonian ICT Association.
Four principles we'll happily get pinned to.
- We deliver, then we leave
- You can take the runbook and walk away after go-live. Most clients don't — but the option matters more than any contract clause.
- Boring stacks, sharp execution
- No bespoke databases, no in-house orchestrators. We pick the boring tool, configure it well, and document the hell out of it.
- EU-resident, EU-paid
- Tallinn HQ, Tallinn taxes. Every euro you pay Blocklyne stays inside the EEA. That matters for some of you, and we get it.
- Audit trails by default
- If you can't prove it to your regulator, it didn't happen. Every Blocklyne system ships with cryptographic audit trails turned on, day one.
