The Startup knowledge base
Underneath the Companion, there is a continuously updated and sourced knowledge base built specifically for founders: the best available knowledge on how to build a startup (fundraising, go-to-market, product, hiring, legal basics and the rest), extracted from public and licensed sources, with the provenance of each document recorded. The first knowledge base that Firmgrove built was the Startup one, created from a manifesto of over 200 cross-referenced sources.
Generative AI spits out work. Firmgrove does the work, audits it against live data, then hands over the decision. It tells you what to do next.
Instead of jumping between point solutions for sales pipelines, financial runway and legal drafts, Firmgrove connects your entire operating stack into one live memory.
Marketing: From Go-To-Market plan to social media content planning.
Sales: Live pipeline tracking where every deal updates the financial model automatically.
Product: Helps you define your product.
Finance: Real-time cash, burn, and runway reconciled against actual metrics, never invented.
Fundraising: Investor pitch deck, cap table, equity story, and data room generated from one audited source of truth.
Legal & Ops: Standard agreements drafted and gated before they ever reach your inbox.

There is no tool to learn. You explain your company once, then you talk, you decide, and Firmgrove does the groundwork, the research, the drafts, the pipeline, next tasks, the deck and the board pack.
It doesn't replace your judgment or decisions. It replaces everything that was keeping them waiting.

Most tools want volume. They take your card on day one, hand you a nice dashboard and don't care if you're gone in three months.
We built Firmgrove the other way around.
Before you can pay us anything, you run your idea through a free evaluation. Score under 70 and the system blocks the upgrade. We won't take your money if we don't think the business works.
Instead you get a breakdown of where the points went missing. Market size, unit economics, no real differentiation, whatever it is. Then a month of free iterations to fix it.

Clear 70 and Firmgrove opens up. From there it runs the company: sales pipeline, runway, fundraising decks, go to market plan, support, legal drafts, weekly execution and more.
You build the dream. Firmgrove runs the company.

Making your own evaluation the gate to becoming a paying customer is a fascinating constraint.
Have you been able to test yet whether the businesses your system scores as stronger actually go on to show stronger real-world traction than the ones it rejects?

Thank you for your question.
No, we haven't validated the score against real-world traction yet. We just started so there's no outcome data to correlate against.
The evaluation isn't a rejection filter, it's a starting judgment. It scores your idea and then tells you what to do next, it doesn't turn founders away.
Or this is what we think. Can you give it a try and tell us what you think please?-

That’s helpful context. The distinction between using an evaluation as a rejection mechanism versus a starting point for decisions is an interesting one.
I’d like to continue the conversation outside the thread. What’s the best email to reach you on?

Most founders spend the week as the integration layer. Eight tools that do not talk to each other and a deck, a model and an investor update that quietly disagree. Firmgrove is the company brain that runs your startup.
