How I built Calbro with AI and got a 33 million credit ElevenLabs grant
I had no coding background. This is how I built the app with AI tools, how the grant works, and how you can apply for it.
What the grant gives you

|---|---|

Part 1: How I built Calbro with AI
Calbro AI is a health app with AI food scanning and calorie tracking. I started in January 2026 and it is live on the App Store, Google Play and calbro.in.
- Pick one real problem. Mine: tracking what you eat is too much work, so scan the food instead.
- Use AI as your developer. I used Claude Code and Google AI Studio. Describe one feature in plain words, run it, then tell the AI exactly what is broken.
- Build one small thing at a time. Get one feature working on your own phone before asking for the next one.
- Let AI explain every service. You don't need to know these in advance. Ask "what does this do, and what does it cost?"
- Get a security review before launch. Ask the AI to check who can see whose data and fix the gaps. Real users trust you with their information.
- Add payments and launch. A product people can pay for matters here, because the grant is for products with a business model.
| Part | What I used | Why |
|---|---|---|
| App | Capacitor | One web codebase becomes iOS + Android apps |
| Backend | Supabase | Login, database and server functions |
| AI | Gemini on Vertex AI | Reads food photos and powers AI features |
| Payments | Razorpay + in-app purchases | Web payments + App Store and Play billing |
Part 2: Have a specific voice idea
ElevenLabs funds voice products, so "I have an app" is not enough. My use case was a Hinglish voice agent that talks to people who asked about Calbro, qualifies them and books them into a paid coaching consultation. I set up a first version in ElevenLabs before I was approved.
Your idea should answer three questions: Who talks to the voice? What does it do for them? How does that make money?
Part 3: Check you qualify
| ElevenLabs' rule | |
|---|---|
| โ | A startup with fewer than 25 employees |
| โ | A product with a business or monetization plan, meant for the long term |
| โ | A valid business email |
| โ | Agencies, consulting firms and SMBs |
| โ | One-off projects and campaigns |
| โ | Products for children aged 18 or under |
| โ | Existing enterprise customers, previous grant recipients, more than one application per company |
Part 4: Apply
- Sign up on ElevenLabs with your business email. The credits go on the account you apply with.
- Open the form: elevenlabs.io/grants-application. Read the terms and continue.
- Tell them about your startup, your team and how you expect to grow. Be specific and truthful. The terms require complete and accurate information.
- Wait for the decision. ElevenLabs aims to reply within about a week, and there is no fixed deadline.
Prepare your answers with this prompt in Claude or ChatGPT:
After you're approved
- Read your approval email. Mine asked for an ElevenLabs Grants badge on the website.
- Track your credits. In my tests a voice agent used about 800 credits per minute, so plan your usage on real numbers.
- Save credits for what lasts. Generated audio files stay with you. Live agent minutes are gone once they are spoken.
- Mark the end date. The plan drops to Free after 12 months, or when only 10,000 credits are left.
- Never sell your credits. Reselling ends the grant immediately.
