ABOUT
Built by people who've seen the problem.
We're not consultants who advise from the outside. We've spent 22 years building real products — and xool is how we offer that to founders who need it.
WHY XOOL EXISTS
We've seen what bad architecture costs.
Between us, we've watched too many startups move fast, ship something, raise money, then spend the next 6 months rebuilding from scratch because the foundation wasn't right.
We started xool because we knew it didn't have to be that way. Speed and architecture aren't a tradeoff. We prove it with every engagement.
Architecture first
We design the system before we write a line of code. Every decision is made with your next 10x in mind.
AI as accelerator
We use AI to move faster but humans own every architectural decision. AI is the engine, not the driver.
Builders, not advisors
We ship things. Every engagement ends with something real your team can run, extend, and own.
THE FOUNDERS
Two perspectives. One direction.
We overlap where it matters and complement each other where it counts. That's what makes the work better.

COMMON QUESTIONS
Questions about working with us.
Who is xool?
xool is an AI engineering studio founded by Hitesh Sharma (CPO, 14 years experience) and Vikas Chamarthi (CTO, 8 years experience). Together they bring 22 years of combined experience building production-ready AI products and infrastructure.
What makes xool different from a typical development agency?
xool designs the system architecture before writing a single line of code. Every product is infrastructure-first — built to scale from day one, not rebuilt 6 months after launch when the foundation breaks.
What kinds of projects does xool take on?
We work on new AI MVPs (4–8 weeks), AI feature sprints into existing products (1–3 weeks), and extended tech team engagements for scaling startups. All projects start with a written proposal defining scope, timeline, and cost.
Let's see if we're a fit.
We work with a small number of clients at a time, by design. Tell us what you're building.
