The Problem

Most startups fail because founders build before they validate.

The tools exist for brainstorming. But nobody built the workflow that comes after — from assumptions to evidence to decisions.

No system to go from "I think" to "I know"

Founders rely on gut instinct and cherry-picked feedback instead of structured validation. There's no workflow to move from assumptions to validated learning — just guesswork dressed up as strategy, and hoping for the best.

Validation is scattered across too many tools

Canvas in Miro. Notes in Google Docs. Transcripts in a folder. Hypotheses in a spreadsheet. The DIY combo of Slides, Sheets, Docs, and Notion is flexible but fragmented — context is lost, collaboration breaks, and nothing connects.

Synthesizing interviews is painful, so founders skip it

Turning 10 hours of interviews into actionable insights is manual, time-consuming, and error-prone. General-purpose AI chatbots help with brainstorming, but conversations vanish — so most founders do synthesis halfway, or not at all.

How It Works

Your team and AI, working as one. Four steps to validated decisions.

Foundry is the shared workspace where founders, teammates, and AI collaborate on validation. Each loop gets you closer to fit.

01

Map your assumptions

Build a canvas with Claude. Each card becomes a hypothesis with a risk score. You see what matters most — fast.

02

Get your interview guide

Foundry generates questions from your hypotheses. Walk into every discovery call knowing exactly what to ask.

03

Capture and synthesize

Drop in transcripts and notes. Claude tells you what validates, what doesn't, and what you haven't explored yet.

04

Decide. Iterate. Repeat.

Translate validated hypotheses directly into roadmap items — every feature decision backed by real customer evidence.

Founders lead. Teams contribute. Claude accelerates.

Ask Claude to brainstorm your canvas, generate hypotheses, or synthesize interviews — while your team reviews, comments, and iterates alongside AI in real-time.

Foundry: Analyze interviews
You
I just finished 5 customer interviews. Can you analyze the transcripts in my Foundry workspace and update my hypotheses?
C Claude
I've analyzed all 5 transcripts in your Foundry workspace. Here's what I found:

3 hypotheses validated — pricing sensitivity, self-serve preference, and integration need all confirmed across 4+ interviews.

1 invalidated — users don't want a mobile app; desktop-first is the clear pattern.

I've updated your Foundry canvas and moved the validated items to your roadmap.

Core Features

Every tool your team needs to validate. One shared workspace.

Founders map the vision, teammates contribute insights, and Claude connects the dots — across your canvas, hypotheses, interviews, and roadmap.

Synthesis

Interview Intelligence

Upload transcripts, surveys, and research. Claude synthesizes interviews, spots patterns across your data, and generates actionable next steps — all in real-time.

Journey Maps

Customer Journeys with KPIs

Map your customer's path from awareness to advocacy. Track metrics at every stage. Know exactly where the drop-off happens.

Hypothesis Tracking

Track and Improve

See which assumptions are validated, which need more evidence, and where you're still guessing.

Interview Insights

Track Your Success

See interview coverage, theme frequency, and evidence strength — all synthesized automatically by Claude.

MCP + Markdown

Your Business 360 — for Every AI Tool

Foundry becomes your single source of truth. Export as markdown or connect via MCP to give any AI tool the full context of your business — feed Claude Code when building features, generate blog content, write ad copy, or power brainstorming sessions.

Collaboration

Real-time Team Sync

We were using Miro, Sheets, and ChatGPT in three tabs. Foundry replaced all of it. One workspace, one source of truth.

I'm a repeat founder and I've never had this much clarity this early. The hypothesis tracking alone is worth it.

FAQ

Good questions.

Is it actually free?+
Yes, fully free during beta. We want founders who'll shape the product with us. Your feedback is worth more than a subscription right now.
How does the AI work?+
Foundry integrates directly with Claude via MCP. It helps brainstorm your canvas, generates hypotheses, writes interview questions, and synthesizes research — all inside your workspace. Think strategic thinking partner, not chatbot.
Do I need to know Lean Canvas?+
Nope. Foundry walks you through each block. First-time founder or seasoned operator — the tool meets you where you are.
How is this different from ChatGPT?+
Chatbots are great for brainstorming, but conversations vanish. Foundry persists your business model, tracks hypotheses, links interviews to assumptions, and gives you a living system. Not a chat thread.
How is this different from Miro or Notion?+
Those are great general-purpose tools, but they don't have a validation workflow built in. In Foundry, your canvas cards automatically generate hypotheses, hypotheses generate interview questions, and interview transcripts get synthesized back into your canvas. Everything is connected — no manual copy-pasting between docs and boards.
Can my co-founder use it too?+
Yes. Real-time collaboration is built in. Align on assumptions, share validation progress, and iterate together.
What happens after beta?+
Beta users get early adopter pricing and a seat at the table for what we build next. There will always be a free tier.

Validate Together. Ship With Confidence.

Bring your team and let AI do the heavy lifting. Join the beta and help shape the workspace where founders find product-market fit — together.
