SaaS development
We build multi-tenant SaaS the way we build our own — tenant isolation, billing, and scale designed in from day one, on an encrypted per-tenant substrate rather than a shared table with a customer column bolted on.
The hard part of SaaS is not the first customer, it is the hundredth — where one tenant's data must never reach another's, where the bill has to be right, and where load has to grow without a rewrite. We design for that from the start: each tenant's configuration and integrations live in their own encrypted store, so isolation is enforced by architecture, not by a WHERE clause somebody has to remember.
This is not a pattern we read about. It is the substrate under Docusift and Lekha — each customer controls their own integrations, model providers, and data flows because that is where the configuration physically lives. It is also what lets a product credibly promise it never sells your data: the promise is built into where the data sits.
What multi-tenant done right needs
-
Isolation by architecture
Each tenant's configuration and data in an encrypted per-tenant store, so a leak between customers is structurally prevented rather than one forgotten filter away.
-
Billing, plans, and onboarding
The commercial machinery a SaaS actually runs on — sign-up, plans, metering, and self-serve tenant setup — built as product surface, not an afterthought bolted to the side.
-
Scalable from day zero
Stateless services, idempotent operations, and coordinated workers, so the infrastructure scales up and out when the customers arrive, without touching the code.
