Test it before you build it
$250 · 5 weeks · 30 prospects
For $250 and 5 weeks, prove that two-partner research shops will prepay $149 and actually log claims on a shared board during a real report instead of pasting agent output into chat.
Riskiest assumption · Both partners of a small research team - not just the one who bought it - will log claims with provenance on a shared structured board during a real paid deliverable, rather than defaulting back to pasting agent output into their existing group chat.
1Focus group: who and where
A partner in a 2-5 person independent research shop or a multi-author paid newsletter, where each partner runs their own Claude or ChatGPT setup and this month's report means findings scattered across two chat histories, a shared doc and a group thread, with conflicting numbers overwritten silently.
where to find 30 · Integrity Research Associates' directory of independent research providers (filter for firms of 2-5 people), the Substack Finance and Technology leaderboards filtered to publications listing two or more authors, r/Substack and Indie Hackers for co-run newsletter teams, and X threads where co-authors publicly describe their AI research workflows.
2Sell first, build later
A founding-team pilot for one report: within 7 days of payment we set up your shared claim board and connect both partners' assistants via MCP on a 45-minute call, you run your next deliverable through it, and every claim carries who found it, which agent, which sources, and conflicts shown side by side instead of overwritten. Includes a debrief and the option to lock $79/month for 12 months.
the ask · $149 per team for the one-report pilot; $79 per team per month afterward, founding price locked for 12 months
a real yes · A real yes is a paid $149 invoice plus a setup call on the calendar with both partners attending. Not a yes: 'we'd try this', one partner signing up alone, a request for a free trial, or praise for the demo board.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Sell 15 paid pilot slots
$150 · 14 days
Email or DM 30 teams from the directory and leaderboards, book 15 calls with both partners present, and pitch a one-report pilot: we build your shared claim board as a Notion database (claim, owner, agent, sources, confidence, conflict flag) and connect each partner's assistant through Notion's official MCP server on a 45-minute setup call - no production code, no workflow migration. Invoice $149 at the end of the call.
keep going if · 5 of 15 teams pay the $149 invoice before their setup call
2. Both-partners usage count
$100 · 14 days
For every paying team, run the pilot through one real report cycle and count claims logged per partner from the Notion database history. The stated risk is that teams default back to pasting into group chat, so the measurement is whether the second partner - not just the enthusiast who bought - posts claims with sources attached.
keep going if · In 3 of 5 paying teams, both partners each log 10 or more sourced claims during the report
3. Convert pilots to subscription
$0 · 7 days
On the day each pilot team ships its report, ask on a 15-minute debrief call for the ongoing subscription: $79 per team per month, founding price locked for 12 months, first month invoiced that day. A pilot that ends with thanks but no renewal is a kill signal dressed as a success.
keep going if · 3 of 5 pilot teams pay the first $79 month on the debrief call
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.
$149
per prospect, refundable
how · The pilot prepaid in full by invoice, payable by card or ACH, with the setup call booked at payment - for a $79/month product the right instrument is the whole pilot up front, because the risk being tested is activation energy, and a team unwilling to move $149 will never move its workflow. The buying partner pays; both partners must appear on the setup call for the slot to count. set up: Stripe Invoicing ↗
what it reserves · One of 10 founding-team slots, a setup call date within 7 days, both partners' assistants connected, and the $79/month price locked for 12 months
refund · Refunded in full if the board and both assistant connections are not live within 7 days of payment, or on request any time before the setup call.
target · 5 paid pilots from 15 calls within 21 days
Go: build it if
5 of 15 teams prepay, both partners log 10+ claims in at least 3 of 5 pilots, and 3 of 5 convert to $79/month - build the standalone board with native MCP support.
Kill: stop if
Fewer than 3 of 15 teams prepay $149, or in 4 of 5 paying pilots the second partner logs fewer than 5 claims - the group-chat default has won and the ledger never clears its activation energy.
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
You and your co-author each run your own Claude or ChatGPT, and by report week the findings live in two chat histories and a group thread where conflicting numbers get overwritten. For your next report I will set up a shared claim board: every finding logged with who found it, which agent, which sources, and conflicts shown side by side - your assistants connect to it directly, nothing about how either of you works has to change. The pilot is $149 for one full report, setup call included. Got 20 minutes this week, both of you?
landing page
Every claim your agents find, on one board, with sources $149 buys a one-report pilot: your shared claim board built and both partners' assistants connected within 7 days, then $79/month locked for a year Prepay and book your setup call - 10 founding teams
deposit terms
Your $149 prepays the full one-report pilot and reserves one of 10 founding-team slots, with your setup call inside 7 days and the $79/month founding price locked for 12 months. Fully refunded if your board and both assistant connections are not live within 7 days, or on request any time before the setup call. Your pilot runs the length of one report, typically 2-3 weeks.

The concept in full
- What
- A workspace for two-to-five person research shops in which each member runs their own assistant and pipelines. Findings land on a shared board as claims with provenance: which person, which agent, which sources, which confidence. Conflicting claims are surfaced side by side instead of overwritten. In the first hour a founder creates a board, connects their own assistant via MCP, and posts three claims from an existing project with sources attached.
- Grounded in (2025-2026 signals)
- 'Multiplayer AI' is a current Fall 2026 YC RFS theme. MCP became one plug any assistant can take when it was donated to the Agentic AI Foundation on December 9, 2025 with first-class support in ChatGPT, Claude, Cursor, Gemini, Copilot and VS Code. MIT NANDA (published August 2025): more than 40% of knowledge workers use personal AI tools at work, meaning small teams are already multi-agent by accident, without shared state.
- What it rides
- Rides the Fall 2026 YC Request for Startups 'Multiplayer AI': collaboration between people who each run agents is named as an open problem, and the brief's collection rules list it among the unbuilt.
- Why now
- YC's Fall 2026 RFS names Multiplayer AI now because the pieces just landed: MCP support across all major assistants since the December 9, 2025 donation makes a tool-agnostic shared layer possible, and MIT's August 2025 finding that over 40% of knowledge workers run personal tools means the multi-agent team already exists and is uncoordinated.
- Wedge: first customer and entry point
- Two-partner independent research shops and newsletter teams where each partner has their own Claude or ChatGPT setup; entry point is one shared board per report, adopted for a single deliverable before any workflow change.
- Closest real companies, as the generator saw them
- Sim is a workspace for building and managing AI agents, oriented at operating the agents themselves; jo is a single-player personal agent. Claimboard coordinates the humans' findings across separately-run agents, which neither addresses.
- Main risk
- Teams default to pasting agent output into a group chat, and the structured claim ledger never clears the activation energy of a new shared tool.
