Powering Voice AI for India (@ycombinator f25)

[bolna @bolna_dev]

The year that went by, bringing many firsts and skyrocketing highs for this rocketship... 2025 was incredibly thrilling for us at @bolna_dev.

Here we go with the flashback... 🧵

[bolna @bolna_dev]

There is a lot that goes into building a voice AI agent before it ever makes its first call. Building one from scratch means accounting for edge cases, guardrails, tone, language, and token limits, often all at once.

Canvas on Bolna makes it simple with all the building blocks in one place. A modular prompt editor with a built-in library of blocks for recruiting, support, sales, and more. Insert what you need, watch the live token counter as you go, and ship in any language with one click.

The blank box is gone and so are the wasted hundreds of minutes spent on iterating an agent.

People don't remember the flow of a conversation but rather how it opened and ended. Kahneman and Fredrickson proved it in 1993 with the Peak-End rule, and the thesis holds just as true for a voice AI call as it does for any human experience.

At Bolna, we analysed this phenomenon in an attempt to lift retention for enterprises across all our calls, and we came across a Midas touch which really differentiated a good call that brought back the customers from an average call that just connected with them for a few seconds.

Across 7.7 million calls in which customers received a genuinely warm closing note, 42% came back for a repeat interaction. Some specific hang-up prompts drove return rates closer to 59%, and the pattern was consistent across both inbound and outbound calls.

For India Inc., a good goodbye was quietly predicting who would call back and offer their loyalty.

A cordial hangup lifts the sentiment the user puts the phone down with. Voice AI that closes with intention shapes the emotional memory your brand leaves behind and is essentially what drives callbacks, lifts retention, and keeps customers from quietly churning.

The last few seconds of a call are your most underrated retention tool.

@agent_bulletin hi @agent_bulletin
can you please share your email id associated Bolna account?

Your team can take five calls a day. But when the volume goes north of, say five hundred, there’s no way your team can read through all those transcripts.

The data keeps piling up and overwhelmingly, nobody touches it ever. Your CRM, operations or business teams keep struggling with all of that goldmine of data, wasted for nothing.

On Bolna, Extractions lets you define exactly those: lead scores, handover triggers, objection patterns, visit details, all of which come back in a schema you control, with confidence scores and reasoning attached to every call.

What else?
Nainsi Srivastava, our Product Manager, breaks it down on our feature spotlight series so that you don’t have to figure it out yourself.

Meanwhile, Sarvagya took Bolna to Mumbai Tech Week and gave the first ever live demo of our upcoming agent builder to a room full of voice AI builders.

Last few days have been quite swamped for Bolna with the team taking over stages across cities.

Maitreya led the conversation at the @Inc42 AI Summit 2026 in Bengaluru on a panel discussing how voice AI is reaching India's next 500M users, alongside Suman Gandham from https://t.co/risCVKJtzo, Nitin Pulyani from Cashfree Payments, and Nikhil S. from Inc42 Media.

Uno Reverse on Recruiters

As a candidate, Lakshya was tired of jumping on 15-minute screening calls with recruiters just to find out the role was not worth his time.

So he built Lord Chotu, a personal voice agent that takes recruiter calls on his behalf, asks about WFH policy and salary budget before he ever gets involved. Best part: it also sends him a summary at the end of day so he can decide if a follow-up with the recruiter is worth his time.

Recruiters have been screening candidates for decades. Lord Chotu, on behalf of Lakshya, screens them back. Talk about Uno Reverse.

We built Bolna to make voice AI accessible for every business. But the part that genuinely gets us excited every single day? Watching how our community tinkers with it to solve the real problems that plague India in the most creative ways.

From pilgrimage support to e-commerce use cases, here's a roundup of some of our absolute favourite builds. 👇🏽

Instant Lead Response from Meta Ads

Jayesh found a gap that most marketing and sales automation teams miss i.e. slow response time and zero follow-up systems after a lead enters the funnel.

He built a fully automated sales ecosystem to synchronise speed and automation. In his sales workflow built with Bolna, each Meta Ads lead instantly triggers an AI call, which kicks off auto-pitching, sends webinar reminders, and updates the CRM. This enabled the sales team to track leads in real time without manually chasing a single lead.

Maitreya Wagh, our Co-founder & CEO, is featured on the @Forbes Asia 30 Under 30 list, Class of 2026.

Maitreya, then 26, founded Bolna with Prateek Sachan in 2024 with a clear conviction: voice AI for India had to speak the country's languages with human-like intelligence. Two years on, that thesis is holding. Bolna continues to prove its mettle as a self-serve voice AI platform for Indian enterprises at an unparalleled scale.

A milestone long in the making, and one he has rightfully earned. Congratulations, @maitreya_wagh!
