  Demo Call

Inspiration:

Most AI voice agents today are either too expensive, locked into enterprise contracts, or lack natural conversation flow. I wanted to build something different, something accessible, fast, and truly autonomous that can cold call, qualify leads, and book meetings just like a human SDR.

The idea for Brib.live was born during the [bolt.new Hackathon], aiming to ship a fully-functional AI calling agent platform in under a week—real voice, real calls, real lead gen.

What it does:

Brib lets you launch AI voice agents that:

• Speak via ElevenLabs
• Understand context using Gemini/OpenAI
• Place outbound calls using Twilio
• Enforce rate limits and GDPR-safe data handling via Supabase Edge Functions
• Collect early access signups and phone leads from a clean marketing site

The core agent, “Alan,” can handle a live phone call from your browser, collect interest, respond to objections, and simulate a real sales call.

How I built it:

• 💻 React + Vite for the frontend
• ☁️ Supabase for auth, Postgres DB, and edge function hosting
• 🔊 ElevenLabs for voice synthesis
• 📞 Twilio for outbound call triggering
• 🧠 LLM for conversation memory + logic
• ⚙️ Bolt.new, Cursor (and ChatGPT) for rapid AI pair-programming
• 🔐 Full RLS, insert-only policies, and privacy-compliant logging

Challenges I ran into:

Getting Supabase migrations + RLS working properly with the SDK (returning: 'minimal' was the hidden fix)

• Edge functions losing in-memory rate-limit maps due to Deno isolate behavior
• Debugging voice call failures between Twilio and ElevenLabs in real time
• Coordinating multi-step flows entirely over CLI with no GUI deploys

Accomplishments that I'm proud of:

• Built and deployed a production-ready AI calling agent platform
• Created GDPR-compliant early access collection
• Made real, live phone calls from the landing page in 3 days
• Learned how to debug voice agents, edge functions, and Supabase migrations all in one weekend

What I learned:

• Built and deployed a production-ready AI calling agent platform
• Created GDPR-compliant early access collection
• Made real, live phone calls from the landing page in 3 days
• Learned how to debug voice agents, edge functions, and Supabase migrations all in one weekend

What's next for brib.

• Add multi-agent campaigns and scheduling
• Enable self-serve billing with Stripe
• Let users build their own voice flows with a no-code drag-and-drop builder
• Integrate CRM syncs like HubSpot & Close.com
