You're earlier than the role you're playing. Duet is AI for startup founders who would rather ship than schedule — it builds the MVP, runs the market research, drafts the deck, and sends the investor update, so you stop being the bottleneck on every function at once. Less hire-the-cofounder, more deploy-the-cofounder.
"I have a rough idea. I need a prototype the team can react to."
Duet ships a working MVP — frontend, backend, deploy — from a spec written like a story. You ship a real product to test the wedge, not a pitch deck — which means real users, real signups, and real conversations with the people who actually want the thing.
"I keep rebuilding the same competitor sheet."
Duet runs deep competitor and market research on a schedule, files findings into a shared doc, and pings you when something interesting moves. Pricing pages, changelogs, LinkedIn posts, hiring patterns — watched continuously without you reopening another spreadsheet.
"I haven't sent an update since the angel round."
Duet drafts the monthly update from your metrics, your chat history, and your roadmap — you edit, you hit send, the cap table stays warm. The same scaffolding builds the board deck the quarter you raise, so you stop starting from a blank Google Slide.
Build the MVP described in /spec/v1.md. Use Next.js + Convex + Resend. Set up auth with WorkOS. Deploy to Vercel and seed the demo data from /spec/seed.json.On a weekly cadence, pull updates from our 8 competitors' pricing pages, changelogs, and LinkedIn posts. Summarize the diff in #market-watch.Draft a 12-slide seed deck using /memos/seed-narrative.md, our latest metrics from Stripe, and the design system in /brand. Output as Google Slides.Draft the November investor update: pull MRR from Stripe, top 3 wins from #wins, the ask for the month, and last month's asks revisited. Email me v1 for review.Share your spec, your brand, your metrics dashboards, and your last investor update. Duet builds a memory of the company so it can write in the founder voice — your phrasing, your numbers, your roadmap, your customers' names — instead of generic startup boilerplate.
Hand off whole functions — research, drafting, MVP build — instead of micromanaging tasks. Duet runs them on cron and pings you for review when there's a decision to make or a draft worth your time, not for every keystroke.
On a regular review cadence, scan Duet's output: the MVP it shipped, the update it drafted, the research it surfaced. Approve, edit, or redirect. The flywheel keeps spinning between reviews, so planning opens with progress instead of a stale backlog.
Or skip the role question entirely and browse use cases by job.
Yes. Duet writes real production code (Next.js, Convex, Supabase, Vercel deploys) from a spec. The goal is a working demo you can put in front of a design partner, with a codebase that is yours to take to GitHub the moment you outgrow no-code.
Coding assistants help you type faster on your laptop. Duet runs on its own cloud server, persists state, schedules work, and handles non-coding functions (research, decks, updates) in the same workspace. For a founder running every function alone, that's a different shape of product — Cursor speeds up Tuesday; Duet runs all five weekdays.
Your workspace is a private cloud server with isolated storage. Stripe keys, board materials, and metric dashboards stay scoped to your org — no cross-tenant exposure and no training on your content. Secrets live in encrypted environment variables that Duet reads at runtime, never logged or surfaced.
Yes. Start solo, invite a cofounder or contractor when you raise. Duet's memory and skills move with the workspace — you don't lose context, and the new hire starts with a teammate that already knows the codebase, the customers, and the unwritten rules of the company.
Usage-based — solo founders can start with a small credit pack while validating. There's no per-seat tax, so adding contractors doesn't multiply the bill. When you raise and ramp output, the line item scales with the work, not with headcount.
The serious ones care about traction, judgment, pace, and burn discipline — not which keys you pressed to ship the build.
Start with one connected workflow, then let Duet run the recurring pieces from your workspace.
