Bolna x Cartesia: Voc-a-thon
Calling all engineers, indie hackers, and product builders. Join Bolna and Cartesia for Voc-a-thon, a hands-on build sprint in Bangalore for people who want to ship real Voice AI products, not just talk about them.
This event is designed for developers, early-stage founders, and operators who are serious about what voice can do and want the space, tools, and company to go deep on it.
Here's how it works: apply now, get qualified by June 5th, and receive credits from Bolna and Cartesia to start building your idea straight away. Spend the week shaping it into something real. Show up on June 13th with a working prototype, walk us through it, iterate with sharp feedback, and demo it to a room that gets it.
Standout builds will walk away with exciting prizes, and the best part is shipping something credible and getting it seen by people who matter in the Voice AI space.
Timeline:
→ May 29: Registrations open
→ June 5: Participant qualification
→ June 5-12: Build period (Bolna + Cartesia credits provided)
→ June 12: Working prototype submission deadline
→ June 13: Hackathon day: presentations, iteration, final demo + prizes
Note: This is a fully in-person event in Bangalore. Space is intentionally limited so every builder in the room gets real attention. Applications are reviewed on a rolling basis.
