Threadkeep
A memory vault you own that every assistant you run can read
Threadkeep is a local-first store of one person's working context, clients, projects, decisions, preferences, exposed as a single MCP server that Claude, Codex, Cursor and browser agents all read and write.

$700 · 3 weeks · 25 prospects
For $700 and 3 weeks, prove that people already running two or more assistants will put $50 down, and commit to $20 a month, to own their memory layer instead of waiting for native memory to sync.
Riskiest assumption · People already paying $100-200 a month for Claude Max plus a Cursor seat will pay $20-40 a month for a memory layer they own, rather than wait for Anthropic's and OpenAI's native memory to reach across their tools.
1Focus group: who and where
A solo consultant or solo-practice lawyer who pays for Claude Max ($100-200 a month), also uses Cursor or a browser agent daily, and this month is pasting the same client background, project decisions and personal preferences into each assistant separately.
where to find 25 · Reddit's r/ClaudeAI and r/mcp, where multi-assistant setups are posted daily (channels); contributors and stargazers of the modelcontextprotocol/servers repo on GitHub, a public list of people who already run MCP endpoints (directory); the Cursor community forum at forum.cursor.com (community); plus one Show HN post for the pre-order page.
2Sell first, build later
A founding seat in Threadkeep's first cohort of 20: run the one-command importer on your Claude and ChatGPT export files, get a deduplicated memory graph served over one MCP endpoint to Claude, Cursor and your browser agent, delivered by October 26, 2026, with a setup call with the founder.
the ask · $20 a month, founding price locked for 12 months (list price $35), reserved with a $50 refundable deposit
a real yes · A $50 charge landing on a card is a yes; an upvote, a 'this is exactly what I need' comment, a GitHub star or an unpaid beta signup is not
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Founding pre-order page
$550 · 14 days
Put up a one-page site: the promise (one MCP memory endpoint built from your Claude and ChatGPT exports), the $20 a month founding price, delivery October 26, and a $50 refundable reservation via hosted checkout. Post it once each to r/ClaudeAI, r/mcp, the Cursor forum and Show HN, and spend $300 on Reddit ads against r/ClaudeAI readers. One founder answers every comment for a week.
keep going if · 8 paid $50 reservations from roughly 400 unique visitors (about a 2 percent deposit rate) within 14 days
2. Multi-assistant pain interviews
$0 · 10 days
DM 25 modelcontextprotocol/servers contributors and active Cursor forum posters with the outreach script; book 15 twenty-minute calls. Ask each to walk through yesterday's actual assistant usage and count how many times they re-entered context by hand; no pitch until the last five minutes.
keep going if · 10 of 15 interviewees re-enter the same client or project context into two or more assistants at least weekly
3. Demo-and-close calls
$150 · 7 days
Build a click-through Figma prototype of the one-command import flow using the founder's own Claude export as demo data. Show it in the last five minutes of each interview and to 5 more prospects who commented on the page, then send the $50 checkout link while still on the call.
keep going if · 5 of 12 demo calls convert to a paid $50 reservation before the call ends
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$50
per prospect, refundable
how · A $50 refundable reservation taken through a hosted checkout link on the landing page and sent live during demo calls; a payment link is the right rail here because the buyer is a self-serve consumer paying a card-sized amount straight from a Reddit or forum click, with nothing to sign. The founder watches the payment land before the call ends. set up: Stripe Payment Links ↗
what it reserves · One of 20 founding seats, the $20 a month price locked for 12 months, and a delivery date of October 26, 2026
refund · Refundable in one click any time before the prospect's own import completes, no questions asked.
target · 12 paid $50 reservations from 25 conversations plus roughly 400 page visitors within 21 days
before taking money · Lawyers in this cohort are bound by client confidentiality rules, so run every import demo on dummy or personal data and take no custody of privileged client files before counsel reviews the data handling.
Go: build it if
12 or more paid $50 reservations within 21 days and at least 10 of 15 interviewees re-entering the same context into two or more assistants weekly: build the importer for the founding cohort.
Kill: stop if
Fewer than 5 reservations after 25 conversations and 400 visitors, or 8 or more of 15 interviewees saying native Claude or ChatGPT memory already covers them: stop.

outreach message
I saw you run Claude Max alongside Cursor, and I am guessing you retype the same client and project context into each assistant separately. I am building Threadkeep: import your Claude and ChatGPT exports once, get one MCP memory endpoint that every assistant you run reads and writes, $20 a month. Before I write production code I am doing 20-minute calls with people who run two or more assistants. Can I book 20 minutes with you this week? I will walk through your setup and show you the import flow.
landing page
Your memory, one vault, every assistant you run $50 reserves a founding seat at $20 a month, importer live October 26 Reserve your vault for $50
deposit terms
$50 reserves one of 20 founding seats and locks your price at $20 a month for the first year (list price will be $35). Fully refundable in one click any time before your import completes. The importer ships to founding members by October 26, 2026; if we run more than 30 days late, everyone is refunded automatically.

The concept in full
- What
- Threadkeep is a local-first store of one person's working context, clients, projects, decisions, preferences, exposed as a single MCP server that Claude, Codex, Cursor and browser agents all read and write. In the first hour a user imports their Claude and ChatGPT data exports, gets a deduplicated memory graph, and plugs the one MCP endpoint into each assistant they run. The vendor memory silos stop mattering because the memory lives with the user.
- Grounded in (2025-2026 signals)
- MCP donated December 9, 2025 with '97 million monthly SDK downloads and 10,000 active servers'; Claude Max launched April 9, 2025 at $100 and $200 a month for people who 'collaborate with Claude extensively'; jo (yc X26, 2026) shows the personal-agent demand this memory layer sits under.
- What it rides
- 'MCP donated to the Agentic AI Foundation': MCP is now vendor-neutral with first-class support in ChatGPT, Claude, Cursor, Gemini, Copilot and VS Code, so one user-owned memory server can serve every assistant instead of each vendor keeping its own.
- Why now
- Since December 9, 2025 MCP is a foundation-governed standard rather than one vendor's plug, and with 97 million monthly SDK downloads every major assistant takes the connection; before that date a cross-assistant memory server had no stable socket to plug into.
- Wedge: first customer and entry point
- Solo consultants and lawyers already paying for Claude Max who also use Cursor and a browser agent; the entry point is a one-command importer for Claude and ChatGPT export files that produces a working MCP memory endpoint in minutes, sold at $20 to $40 a month.
- Closest real companies, as the generator saw them
- jo (yc X26) is the personal agent itself, memory locked inside it; Threadkeep is the memory layer under any agent. Alpha Research (yc X25) builds agentic knowledge bases for public knowledge, not one person's private context. Tinfoil (yc X25) does encrypted inference, not portable memory.
- Main risk
- Anthropic and OpenAI ship native cross-device memory good enough that users accept vendor lock-in rather than owning the layer.
