Building LeadDuo s real-time engine was the hardest and most fun part. I used Inngest to orchestrate all the background workflows that happen the moment a form is submitted scoring the lead with OpenAI, storing metadata, updating the pipeline, and pushing real-time changes via Upstash Redis. Everything runs on Vercel + Next.js, which gives me fast edge functions and a clean dev experience as a solo founder.

I also built separate AI micro-agents that handle specific jobs: one agent scores leads, another triggers notifications (Slack, Airtable, Notion, webhooks, SMS, email), and a third replies directly to the form submitter. Each agent runs as its own Inngest function, which keeps things reliable even when multiple integrations fire at once.

Hey everyone!

I m excited to launch LeadDuo today a tool that helps you never miss a lead again (instant SMS/email alerts, AI lead scoring, unified inbox, and a clean pipeline view).

I ve lost a surprising number of leads in the past simply because I didn t notice the incoming email soon enough.

When I started talking to other indie founders, almost everyone admitted the same thing their contact forms go to inboxes no one checks quickly.
