Founder-led, and in-house.
You talk to the person doing the work — whether that's the site you launch or the test that protects it. No account manager relaying your questions to someone else. The founders scope the engagement, do the senior work, and review everything that ships, backed by an in-house team we've built and trained.

That's not a knock on the person who ends up building your site or running your test — it's how most shops are structured, and it means the person who quoted you isn't the person doing the work, and often isn't the person you can reach when something goes wrong.
We built Quantis Sphere the other way round. Subin and Thejaswini are engineers first — a security and infrastructure specialist and a data and systems specialist — who happen to run the business too. The call you book, the plan you get, and the work you pay for all come from the same two people.
The two people behind every engagement.

A small in-house team, not a bench of subcontractors.
We've hired and trained our own engineers for build, QA, delivery and monitoring — the people who write code, test it, and keep an eye on it after launch. They work under the founders, not instead of them: every engagement is scoped by a founder, and every deliverable — a page shipped, a finding written up, a server change — is reviewed by a founder before it reaches you.
That's the trade-off we've chosen: we don't outsource to whoever's cheapest that week, and we don't scale past what the founders can personally stand behind.
How we work with you
- You meet a founder on the first call — Subin for security and infrastructure, Thejaswini for data and systems
- A founder scopes the work and agrees the price before anything starts
- The in-house team builds, tests and monitors it, day to day
- A founder reviews every deliverable before it ships
- You keep the same founder's direct contact for the life of the engagement
