Hack #9: Stripe

Build something people will actually pay for using Stripe and ElevenLabs, then submit a high-quality viral-style video demonstrating what you've built.

Stripe is the financial infrastructure platform for the internet. Millions of businesses use Stripe to accept payments, send payouts, and manage their businesses online. Use Stripe's APIs to add payments, subscriptions, invoicing, or any other financial functionality to your project.

ElevenLabs offers state-of-the-art voice AI — text-to-speech, voice cloning, sound effects, music generation, and conversational AI agents. Combine Stripe's payments infrastructure with ElevenLabs' audio APIs to build something people want to pay for.

What we're looking for

We want to see projects that solve a real problem and have a clear path to monetization. Build something useful, integrate Stripe to handle payments, and show us why people would pay for it.

Some ideas to get you started:

• Voice-powered SaaS tools — productivity apps, creative tools, or utilities with voice interfaces
• AI audio services — voice cloning, custom TTS, or audio generation as a paid service
• Subscription-based experiences — content, entertainment, or education with recurring payments
• Marketplaces — platforms where creators can sell voice content or audio services

Getting started

Sign up for a Stripe account and use test mode to build without processing real payments. Integrate ElevenLabs APIs to add voice and audio capabilities to your product.
