Home › Who We Are › About

We help companies understand AI, decide what to do with it, and put it to work.

EigenSpark is an AI and technology engineering firm. We advise, we build, and we train the people who run what we build.

Our purpose

To leave a company able to run AI without us. Every engagement is scoped to a number the business already tracks, and it ends when the client’s own team is operating the system in production.

Both founders on every engagement

The person who scopes your problem is the person who writes the code for it. Nothing waits to be explained to a delivery team, and you always know who to call.

Built on your systems, with your people

Your engineers work alongside ours, on your data, inside your infrastructure. The engagement is designed to end, and it ends when your own team is running the system.

The sector before the technology

Credit risk at a public sector bank and valuation at a listed REIT run under different rules. We have built in both, so the rules are where the design starts.

The team

Two founders, and you work with both of them.

Sonam Choudhary, Founder and CEO

Founder & Chief Executive Officer

Sonam Choudhary

Sonam built the banking vertical at Loylty Rewardz, selling to and then delivering for one bank after another. She led Tata Motors into the South African market. She founded a healthtech venture and sold it. She holds an MBA from IIM Ahmedabad, and the Aurora Tech Award named her one of the top thirty female AI founders worldwide.

At EigenSpark she works with the people who sign off: chief executives, boards, and the functional heads whose numbers the project will be judged on. Her rule for scoping is that if nobody inside the company owns the number a use case is meant to move, we do not start it.

Bheeshma Tanna, Founder and Chief AI Officer

Founder & Chief AI Officer

Bheeshma Tanna

Bheeshma designed and built the analytics platform behind one of India’s largest coalition loyalty programmes, and has led product and data engineering at Tata Teleservices and at several startups since. He has trained engineers, analysts and leaders in banking, steel and the public sector to use AI on their own work.

He is the architect on every system we ship, and he builds on the client’s own infrastructure from the first week, with their engineers in the room. A model that works on a clean extract still has to survive a core system built thirty years ago and a file whose format changes every month, and that is the part he designs for.
