- 02
Make the critical path stronger
We focus on the work that improves resilience, delivery speed and measurable performance.
- 03
Leave teams more capable
Clear technical decisions, practical documentation and a platform your team can operate with confidence.
In-house product
We don’t only build for clients — Datar runs its own product in production, around the clock.
MERCURY LEDGER
Market research,
written down.
Mercury Ledger is Datar’s in-house market-research product: an always-on system that captures market microstructure around the clock and seals every observation into a permanent evidence ledger — so every idea is judged against recorded reality, not recollection.
Built, deployed and operated end-to-end by Datar. The same engineering discipline we bring to client platforms, proven daily on our own infrastructure.
