This is nothing.
One day @lovebabbar3 ne @amazonIN me semicolon nhi lagaya. Us din pure India me kisi ki delivery nhi hui.

One of the most bizarre stories from Meta was when an intern brought the entire Facebook site down in 2013 just by using her initials as the internal username. This caused the entire production release to fail.

Her initials were “www”.

New drop: @cartesia's latest TTS model, Sonic 3.5 is now available on @bolna_dev.

This latest ship from Cartesia is noticeably faster, more expressive, and better at handling real conversations.

Best part: We're picking up the tab for you. All Sonic-3.5 calls are free for new and pay-as-you-go users through the end of the month.

Plug it in your voice AI agents and show us what you build.

Indian Voice AI space just got a big update.

GPT-Realtime-2 (speech-to-speech) and GPT-Realtime-Whisper (speech-to-text), @OpenAI's latest voice models, are now exclusively live on @bolna_dev.

Multilingual, fluent in Indian languages, and built for voice agents that can tackle complex reasoning, perform actions, handle interruptions, and keep conversations seamless.

If you've been building voice AI for India, you'll feel right at home with these models.

Try it on the Bolna dashboard and tell us what you think.

[Rajnish Kumar @ooyeraju]

Why to reduce the overall intelligence of the model? :p

[Rajnish Kumar @ooyeraju]

@ivanburazin Your remember the og Airchat?

[Rajnish Kumar @ooyeraju]

The result?
Better conversations, higher quality leads, and the sales team focusing on what they do best — building relationships.

This also helped the client significantly improve their sales conversions.

[Rajnish Kumar @ooyeraju]

I keep hearing, “AI is going to replace humans.”

I actually think the opposite.

AI will help humans do more of what they’re best at.

[Rajnish Kumar @ooyeraju]

Recently we at @bolna_dev worked with a client where an AI voice agent handled the first call with every lead.
The AI identified interested prospects and then passed those conversations to the sales team.

And today Ola drivers do the same to me. 😢

[Deep @DeepStarts]

Bhavish Aggarwal was travelling from Bangalore to Bandipur.
Midway the driver stopped.
Started demanding more money than agreed.
Bhavish refused.

Driver left him on the highway and drove away.
No signal. Middle of nowhere.
He stood there and made a decision.

Quit Microsoft the next week.
Filed 2 patents there. Published 3 research papers.
Left all of it on the table.
Started Ola from scratch in 2010.

A cab driver abandoning him on a highway cost him one afternoon.
And gave India its largest cab company.
One bad ride.
$7 billion company.

@maitreya_wagh & I are proud to announce @bolna_dev's $6.3M seed round!

Two years ago, we set out to build India's API-first platform for voice AI orchestration.

We believe businesses should be able to choose their models, test & deploy multilingual voice agents at scale.

[Rajnish Kumar @ooyeraju]

The future of Voice AI India looks good, because it is in good hands.

[Maitreya Wagh @maitreya_wagh]

Proud to share that @bolna_dev has raised a $6.3M seed round, led by @generalcatalyst, to make Voice AI the default mode of communication for Indian businesses.

More detailed posts on learnings, gratitude, and plans soon.

Not entirely sure why the @bolna_dev office is suddenly buzzing with so much energy...

[bolna @bolna_dev]

Last year, India spent over 4.1M+ minutes on call with us.

Yes, that's millions of real conversations powered by Bolna’s Voice AI Agents across Hindi, English, Tamil, Marathi, Bengali, Kannada and many more Indian languages.

This is where real business happens: on calls, at scale, in the languages India actually speaks.

@bolna_dev is built for Indian businesses, trained on Indian conversations and deployed across critical workflows and use cases for Indian customers, in the languages India actually speaks.

And that’s how Bolna AI contributed 4.1M+ minutes of meaningful business conversations last year.

This is the first snippet from Bolna's Year-in-Review.
As we enter a new phase of growth in 2026, we’ll be sharing more hard-earned insights and defining milestones from the year gone by.

Watch this space for more.
