Being a solo founder is mostly a memory problem. You're the CEO, the head of product, the head of sales, the head of customer support, and the person who remembers why you decided to price it that way six months ago. There's no one to turn to and ask, "What did we decide about the enterprise tier?" The answer is in your head, or in a Slack DM you can't find, or in a notebook you abandoned in March.
Most founders I know solve this badly. They keep decisions in a Notion doc that nobody updates, in a Linear that only tracks tickets, in their head until they forget. The context rots. Six months later they reverse a decision they already made, because they don't remember making it.
Eigen Mesh is the memory bank I wish I'd had. It's not a CRM. It's not a project tool. It's the layer underneath all of them — the place where the raw context lives, in your own words, available to every AI tool you use to run the company.
The meeting you don't have to re-read
Here's the loop most founders are stuck in. You take a meeting. You record it. You get a transcript. You get a summary. The summary goes into a doc. Six weeks later you need the decision. You search the doc. You can't find it. You search the transcript. You find it. It takes twenty minutes. You do this five times a week. That's a hundred minutes a week of looking for things you already knew.
Eigen Mesh changes the loop at the capture step. After the meeting, you say the thing that mattered — out loud, in ten seconds. "Decided: enterprise tier starts at 50 seats, not 25, because the procurement team at Acme said anything under 50 doesn't get a security review." That's the entry. The transcript can rot. The decision is saved.
When you're in Cursor three weeks later, drafting the pricing page, you ask: "What did I decide about enterprise?" Your memory answers. You don't open the transcript. You don't search Notion. You ask, in the place you're already working, and it's there.
The decisions you don't reverse by accident
The expensive failure mode for a solo founder isn't the wrong decision. It's the same decision, made twice, in opposite directions, three months apart, because you forgot the first one.
I keep a running list in Eigen Mesh. Not a journal — a decision log. One line each. "April 12: killed the mobile app, focusing on web for the year." "May 3: hired the contractor for design, not agency, because the agency wanted a six-month retainer." "June 18: pricing goes up in August, not July, to land after the feature ship."
When I'm about to reconsider something, I ask first. "What did I already decide about pricing?" The memory answers. Sometimes the answer is "you already changed your mind once, here's why, here's the new direction." Sometimes it's "you decided this in April and the reason still holds." Either way I'm not flying blind into my own past.
The context that follows you between tools
The reason this isn't just a notes app is MCP. Eigen Mesh speaks it. So the memory isn't trapped in one window.
I'm in Cursor, writing the changelog, and I ask: "What shipped this month?" My memory answers — because I captured the ship notes there. I'm in Claude, drafting a pitch email, and I ask: "What's the context on the Acme deal?" Same memory, same answer. I'm in a new research tool I'm trying out, and it supports MCP, so I point it at Eigen Mesh and it knows my company immediately. No onboarding. No "tell me about your business."
The memory lives in one place. The tools come to it. I don't re-explain my company to every new assistant I try. I explain it once, and then I continue.
The part that actually saves you money
There's a quieter benefit. When your context is portable and yours, you can switch tools without paying the context tax. You can try the new model that just launched. You can leave the tool that got worse. You can pick the best interface for the task at hand, instead of the one that happens to have your history locked inside it.
For a solo founder, this is real money. You're not stuck on a $200/month plan because the alternative is losing six months of context. You can move. The memory moves with you.
What it costs, and what it doesn't
100 free credits — about 100 to 150 thoughts, which is a couple of weeks of decision-logging for an active founder. After that, €3.99 a month. Less than a single coffee in any city you'd incorporate in. Self-host it for free if you'd rather run it on your own hardware (Apache 2.0, github.com/hikaru90/eigen). Hosted version runs on EU servers. We don't train on your data — your decisions, your client names, your pricing logic stay yours.
If you're the only one who remembers
If you're the founder, the head of product, and the institutional memory of your company — and you're tired of being the only one who knows where the bodies are buried — try handing some of it to a memory that holds it for you.
