One engineering platform, and the products that prove it.
Tanvrit was founded in 2023 in Sasaram, Bihar. The first thing built was not an app — it was the shared layer underneath one: a Kotlin Multiplatform SDK that handles authentication, storage, networking and sync, and compiles to 6 native targets.
Everything since has been a test of that decision. There are now 9 products on it, spanning commerce, community, education, developer tools and infrastructure — separate brands with separate users, built and released by the same small team from the same codebase. The portfolio is the evidence; the platform is the product.
What we believe
🇮🇳
Built where it is used
The team works from Sasaram, Bihar. Variable connectivity, shared devices and vernacular input are not edge cases we read about — they are the conditions the software is written in.
🔒
Offline by default
Software that stops when the connection stops is not finished. Reads come from a local store, writes queue in a sync ledger, and the app keeps working until the network returns.
🧱
One platform, many products
A shared SDK is a hard constraint: 25 modules and one API have to serve 9 products at once. It costs more up front and pays back on every fix that lands everywhere.
📐
Claims carry a source
Every number on this site is stored with the command that re-derives it and the date it was last run. That is how 11,600+ tests stays one number instead of two that disagree.
Where it has been taken
Five domains, one SDK. Each one asked something different of the foundation, which is the point of building it that way.
