About us
Tathya means fact.
We build software that deals in them.
Tathya Technologies Private Limited (OPC) is a software development company based in Kolkata, India. Everything we ship — subscriber counts, attendance punches, document fingerprints, invoices — exists to make one thing true: the system's record matches reality.
Who we are
A product company that also builds for clients
We are engineers first. Our own platforms — OrbOS for internet service providers, UniPunch for biometric attendance, TalentHub for recruitment, Tathya Drive for documents and EduDesk for schools — carry live traffic and real money every day. That production discipline is what clients hire when they bring us custom work.
- Founded and headquartered in Kolkata, West Bengal, India
- Products in production across telecom, HR, education and enterprise operations
- We operate what we build — 24×7 systems, monitored and supported by us
- India-first engineering: GST, bilingual interfaces, Tally-friendly exports

Migrations, integrations and new modules as you scale
How we work
Principles we don't negotiate
Production is the proof
We demo from live systems, not mockups. If a feature is on this website, it exists and is running somewhere real.
Data you can defend
Audit trails, cryptographic fingerprints and compliance-grade logs are defaults across our products — because someday, someone asks.
Straight answers
If an off-the-shelf tool serves you better, we'll say so. Long relationships beat one-time invoices.
