Premise takes your raw idea and pressure-tests it the way a seasoned co-founder would, builds the complete, investor-ready document suite you need to raise — then puts you in front of the investors looking for it.
What founders are saying
The process felt much closer to sharing a business idea with a skeptical friend than with an AI. It pushed back hard on my assumptions and didn't just tell me I had a good idea. Most AI tools say 'Great! Here's how it could work.' Here, I had to fight to keep the idea alive, which is exactly what you want.
I was blown away by Premise. I thought I had every detail of my investor pack nailed down, but it opened my eyes to a few important weak points.
You've built an exceptional product. As someone who's raising right now, seeing my venture through a different lens is invaluable, and Premise gives me exactly that.
A really thorough understanding of our ecosystem and product, just from our deck. Quite astonishing, really.
I honestly felt like I was talking to a real person. The replies were so logical, it dug deep into how I think, and it asked about the real-life moment that got me thinking about this idea in the first place.
The problem
And almost everything built to ask them still sends you outside yourself — to an expensive advisor, an oversubscribed accelerator, or a network you don't have. Premise gives that power back to the founder: an independent, in-your-pocket co-founder that takes you from raw idea to raise on your own terms — no gatekeepers, no five-figure retainers.
The best strategic help — advisors, co-founders, venture pros — is expensive, exclusive, and unevenly distributed, and nearly every tool still sends you outside to find it. Well-connected, well-funded founders win; everyone else is priced out or left guessing.
Most founders don't know to ask about their 18-month moat, their competitive blind spots, or why their TAM figure is unsourced. They don't know what they don't know.
A blank page is terrifying. Most founders spend weeks producing materials that still don't hold up in a real investor conversation.
Why Premise
Every other tool solves one slice: a chatbot answers questions, a deck tool formats slides, a dealflow site lists startups. Premise owns the entire journey — and now both sides of the table. It takes you from a raw idea to a pressure-tested, investor-ready venture, then puts you in front of vetted investors looking for exactly what you're building.
You arrive with a concept — nothing formalized yet.
Premise stress-tests it like a skeptical co-founder, one question at a time.
Five coherent documents that build on each other, not five disconnected files.
Practice the real investor and customer conversations, and get a candid debrief.
Get discovered by vetted investors whose thesis matches what you're building.
Cover a single step and hand you off. You're left stitching a chatbot, a deck maker, a spreadsheet, and cold outreach into something coherent — and doing the hard thinking alone.
One continuous system from idea to raise, that remembers your venture the whole way — and a two-sided marketplace that connects serious founders with serious investors. The whole roadmap, both sides of the table.
Pricing
Your first venture and its full document suite are free, with a taste of everything after it. Investors, funds, and accelerators get their own plans for finding what's worth backing.
One full venture, start to suite.
The full co-founder, unlimited.
How it works
Not a one-shot generator: a loop you come back to as your venture takes shape.
The deliverables
The sharpest distillation of your venture — the document an investor reads first.
A phased, executable plan with decision gates, grounded in what's actually buildable.
An honest assessment of what's proven, what's plausible, and how to de-risk it early.
The story arc for your raise, built on everything established before it.
Positioning, voice, and identity foundations derived from the full body of work.
Why not just an LLM?
Premise isn't a chatbot with a nicer prompt. It runs a structured process on your specific venture, pushes back on weak assumptions without being told to, keeps your five documents consistent with each other, and hands you a suite you can actually take into the room.
Answers the questions you bring and tends to agree with you. It can be prompted to push back, but you have to know what to ask, in what order, and how hard. The blank-page problem in a new window.
Gamma, Tome, and Beautiful.ai make slides look good — but they're output tools. They require you to already know what to put in them.
YC, fractional advisors, and incubators offer real strategic thinking — but they're expensive, exclusive, and oversubscribed. YC accepts under 1%.
A candid co-founder that knows your venture, pressure-tests it like a skeptic, guides you from raw idea to investor-ready, and lets you rehearse the real conversations before they happen — so you leave sharper than you arrived.
Questions
A guided conversation that builds five investor-ready documents — one-pager, founder roadmap, feasibility & POC report, pitch deck narrative, and brand overview — each tailored to your venture and exportable. Upgrade to keep refining them and to rehearse your pitch.
About 15–20 minutes of focused conversation to produce your full five-document suite. The more honest detail you bring, the sharper the output.
No. Premise calibrates to you — whether you're technical, business-minded, or starting completely fresh with just an idea.
A general AI chat answers what you ask and tends to agree with you. Premise runs a structured interview on your specific plan, pushes back like a skeptic without being prompted to, runs a real plan-revise-rehearse workflow, and produces five documents that stay consistent with each other.
Yes — Premise is two-sided. Investors apply for access (free during our private beta, and hand-reviewed to keep the bar high), then browse pressure-tested ventures by sector and traction, see the ones that match their thesis, and request warm intros. Founders stay in control — they choose what's shared and approve every intro before any contact is exchanged.
Yes. Advisors, consultants, and accelerators use Premise to build and refine a client's suite, then export it as one polished PDF with a cover, contents, and page numbers. One setting applies your own colors across the documents, and Premise branding on the cover is optional.
Free to start: one full venture and its five-document suite, no card, plus 5 Revise messages, one consistency check, one pitch and one customer rehearsal, one validation kit, and a free week listed for investors. Founder is $20/mo for unlimited ventures, Revise, rehearsals, the suite export as one PDF, and an investor listing with no end date. Investors are free during the private beta. Funds, accelerators, and larger organizations can talk to us about team plans.
Yes. Your projects and documents are tied to your account and aren't shared with anyone unless you choose to list your venture for investors. Even then, you decide exactly what's shown (stealth by default, with no name or sensitive details), and no contact is exchanged until you accept an intro.
Yes. Premise is AI, and like any AI it can get things wrong. It flags figures and competitor details that need checking, and the consistency check catches contradictions across your documents, but you're responsible for verifying figures, competitors, and claims before you share anything.
Build your first investor-ready suite free — about 15–20 minutes, no credit card.
