We build the infrastructure
the world runs on.

Fonabit was founded on a single belief: that the best enterprise software is built where constraints are greatest. India's regulatory complexity, language diversity, and transaction volume produced something Twilio never could — a platform genuinely native to the most demanding markets on earth, ready for the rest of the world.

01
Native infrastructure — not a reseller
We own the carrier connections, routing infrastructure, and compliance stack. Every message travels a direct path we control end to end.
02
AI that runs in-house first
90% of queries route to our own open source models before escalating to peer LLMs. You get intelligence without the premium.
03
Agentic — humans in command
Agents handle execution. Humans control critical decisions. Every workflow has clear audit trails and approval gates.
Our story
Built where it's hardest.
Deployed everywhere.

We spent years building enterprise communication infrastructure for India's most demanding industries — banking, telecom, healthcare, government. We became expert at TRAI compliance, multi-language voice AI, and real-time transaction volumes that would break a typical CPaaS stack.

When we brought that infrastructure to global markets, we discovered something unexpected: the constraints that made us build better also made us more powerful. The platform that could handle India's DLT/OTP requirements at 3,000 SMS/sec handles A2P 10DLC compliance on the same infrastructure. What started as necessity became our competitive advantage.

Today Fonabit runs Aibit — an AI-native workspace — and Netbit — a native CPaaS that outperforms Twilio on delivery rate, latency, and cost. Built in Gurugram. Incorporated in Delaware. Deployed in 190+ countries.

Our thesis
Three ideas that drive everything
Thesis 01
Constraints produce better software
The features you need to serve India — TRAI compliance, Indic language AI, UPI payment flows, 12-digit phone numbers — produce infrastructure that handles every other market with room to spare. We didn't build for the easy case.
Thesis 02
Agentic AI needs humans in command
The most powerful AI deployments are not autonomous. They are hybrid — AI handles execution, humans retain authority over critical decisions. We build human-in-the-loop gates into every agentic workflow as a first principle, not an afterthought.
Thesis 03
Own the infrastructure or lose the margin
Every reseller layer adds cost and latency. We own the carrier connections, the routing tables, the compliance stack. This is what lets us charge 35% less than Twilio and deliver 7% higher delivery rates simultaneously. Ownership is not a cost centre — it's a moat.

Origin story — Spark
The spark that started
inside the family.

A daughter who saw a gap. A brother who could build the solution. A father whose entire career proved both of them right.

Apoorva Sharma didn't set out to build a company. She set out to solve a problem she kept seeing — in San Francisco, in Silicon Valley boardrooms, and later across India's fast-moving enterprise landscape: the gap between what AI promised and what businesses could actually deploy.

Armed with an Economics degree from Penn State and years of ground-level experience across both sides of the Pacific, Apoorva understood something most AI founders miss — that adoption isn't a technology problem. It's a communication problem. A workflow problem. A trust problem. The intelligence existed. What was missing was the infrastructure that could carry it — reliably, compliantly, at scale.

So she came home. And she started building.

She called her brother.

"I'd watched my father spend 25 years building the pipes that India's digital economy runs on. I grew up knowing that the infrastructure layer is where the real value is created — and the real problems live. When I came back from San Francisco, I didn't want to build another app. I wanted to build the layer underneath."

Apoorva Sharma
Co-founder · Spark
Economics graduate from Penn State University. Built her career across Silicon Valley's enterprise technology sector, working inside the companies shaping global digital infrastructure. Returned to India with a rare dual lens — the rigour of US enterprise markets and the scale of India's opportunity. Saw the gap between AI capability and real-world business deployment. Founded Spark to close it.

Arnav Sharma
Tech co-founder · Spark
Computer Science student at UC Davis, California. When his sister called with the idea, Arnav didn't just understand it — he could build it. His technical foundation, combined with an instinct shaped by growing up in a household where enterprise technology was dinner-table conversation, gave Spark its engineering core. The sibling dynamic — one who understands the market, one who builds the product — is older than Silicon Valley. It works.

Pawan Kaushal
Founder & CEO · Fonabit · Father
25 years building India's digital infrastructure — Airtel, VSNL, MeitY, and now Fonabit. Pawan didn't just build a company in front of his children. He built a belief system. That technology is a craft. That constraints make you better. That infrastructure ownership is a moat. Apoorva and Arnav grew up watching that ethos play out at work and at home. When the time came to build, they already knew what mattered.

The inheritance that matters most
Not capital. Not connections.
A way of seeing problems.

Pawan Kaushal spent a career proving that the hardest problems — carrier-grade reliability, multi-regulation compliance, real-time transaction scale — are exactly where the most durable companies are built. His children absorbed that. Apoorva took it to San Francisco, studied how enterprise buyers think, and returned with a sharper version of the same conviction. Arnav took it into his Computer Science degree at UC Davis and built with it. The spark wasn't a single moment. It was two decades of watching a father do the work, then deciding to do it too — but for the next generation of the problem.
