NOT A PITCH-DECK HACKATHON
Build it.
Then sell it.
Flat Hack 605 brings 12 experienced builders into one flat for a continuous 32-hour race to build, launch, acquire customers, and generate real product revenue.
Bring a new idea, an unfinished MVP, or a deployed product that has never made money. What matters is what your team can ship—and who is willing to pay for it—inside the official window.

Who can apply?
Experienced builders aged 18 or older may apply in two-person teams. There are no college, employment, or institution restrictions.
Can we bring an existing product?
Yes. An unfinished MVP, prototype, or deployed product is eligible if it has not previously generated revenue. Only new eligible sales during the event count.
What can we build?
SaaS products, AI applications, software tools, mobile or web applications, developer tools, and other legitimate software-based digital products.
Do sales from friends count?
A genuine customer purchase may qualify regardless of personal connection, but self-payments, fake transactions, circular payments, refunds, and manipulation never count.
How are payments verified?
Organizers intend to provide identifiable temporary Razorpay payment links, subject to provider approval. Final settlement, refund, and exchange-rate rules will be published before the event.
What exactly does the winner receive?
The first team to reach $100 in verified eligible revenue receives one GPU in total, stated by organizers at ₹80,000. The model, condition, transfer, and tax terms are still to be disclosed.
What happens if nobody reaches $100?
There is no fallback winner. The GPU remains with the organizers, even if one team has the highest revenue below the target.
Where is Flat 605?
The event is in person inside Flat 605. The full address and arrival instructions are shared only with selected teams.
Do participants need to stay awake on camera for 32 hours?
No. Teams may take appropriate rest breaks. The continuous stream does not require every participant to remain awake or visible throughout.
