i m Madhav and i don't prefer to build something with investors.

I had an idea. I had a plan. And the first thing people asked was, "Have you talked to investors?"

My answer was no. And it still is.

Not because I couldn't. But because I genuinely believe the best infrastructure gets built when you're obsessed with the problem, not the pitch deck. Investors optimise for scale before depth. I wanted to go deep first.

So I bootstrapped.

Every line of code, every architectural decision, every late night, 100% our own. No external money, no board telling us what to prioritise. Just a problem worth solving and the patience to solve it right.

The problem? AI voice calling infrastructure is a mess. Most teams building voice agents today are duct-taping wrappers on top of existing platforms, and then wondering why their agents sound robotic, break under load, or cost a fortune to scale. The underlying infra was never designed for what people are trying to build with it today.

That's what we're working on. Not a wrapper. The layer beneath the wrapper.

It's early. The site isn't even pretty yet (vaaadai.com don't judge). But if you're building anything in the voice AI space, or just curious about what "real infra" looks like when someone builds it without shortcuts, I'd love to connect.

More soon.

Love the bootstrap mindset and going deep on voice AI infra, Madhav! That's the way to build something solid. I'll check out vaaadai.com.

If you're up for it, I'm launching The Sponge on PH soon...an AI-powered flashcard app that turns webpages into study material with spaced repetition. Would appreciate a follow (PRODUCT HUNT LAUNCH link in my profile).

@rianbrob definitely, this solution is a must have for a dev who uses AI to code for him, since he can't go through all the documentation he can use these flash cards to mug up everything he needs to know before going ahead.
