$600 · 3 weeks · 25 prospects
Prove that teams already sharing prompts in git and Notion will prepay $150 for a reviewed, auto-syncing skill library - for $600 in 3 weeks.
Riskiest assumption · A founder whose team already lives in git will pay $15 per member per month for reviewed, auto-syncing skills instead of keeping a free repo with a README - concretely, at least 1 in 4 such founders will prepay a $150 first month within two weeks of seeing both options side by side.
1Focus group: who and where
Founder or tech lead of a 5 to 15 person US software agency or product startup where every member pays for their own Cursor, Claude Code or Copilot seat, the team's prompts live in Notion docs and pinned Slack messages, and someone complained this month that a teammate's agent did the task differently because they used a stale prompt.
where to find 25 · Community: r/cursor and r/ClaudeAI subreddits plus the official Cursor forum (forum.cursor.com), where team leads already post about sharing rules files and prompts. Directory: Clutch.co filtered to US software development agencies with 2-9 and 10-49 employees, which lists founder names and emails. Event and channel: AI Tinkerers meetups in NYC, SF and Seattle, and the Latent Space Discord, both full of leads running mixed Claude-Cursor-Copilot teams.
2Sell first, build later
Packroom founding team setup: we convert your 10 most-used prompt docs into versioned SKILL.md skills, set up your private team library with propose-and-review before anything merges, and turn on sync into each member's Claude Code, Cursor and Copilot - live within 14 days of payment, limited to the first 10 teams.
the ask · $15 per member per month, founding price locked for 12 months; month one prepaid at $150 flat for up to 10 seats
a real yes · A real yes is a completed $150 checkout with a named team and a start date. Stars on the free template, 'we would totally use this', requests for a free trial and unpaid pilots do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Prepay versus free repo
$250 · 14 days
Book 20 calls with founders sourced from the three channels above. On each call show two options side by side: a free public GitHub template (a skills folder with a README and a naming convention) they can copy today, and the paid Packroom founding offer - top 10 prompts converted to versioned SKILL.md skills with review-before-merge and auto-sync into each member's Claude Code, Cursor and Copilot, live in 14 days, $150 prepaid for month one. Ask them to choose and, if they pick paid, to check out on the call.
keep going if · 5 of 20 teams prepay $150 on or within 48 hours of the call; fewer than 2 prepays with 15+ calls done means the free repo is winning
2. Free git template control
$150 · 14 days
Publish the same free GitHub template publicly and post it to r/cursor, the Cursor forum and the Latent Space Discord with an honest write-up. The README's last section links to the paid upgrade page: review workflow plus auto-sync for teams, $150 first month. This measures whether people who already got the free git version still pay for sync.
keep going if · Of the first 100 accounts that star, fork or clone the template, at least 5 click the paid upgrade link and at least 2 complete the $150 checkout within 14 days
3. Manual sync delivery week
$200 · 10 days
For each prepaid team, deliver by hand before writing product code: convert their top 10 prompt docs into SKILL.md folders in a private GitHub repo and give each member a one-line install script that symlinks the skills into Claude Code, Cursor and Copilot. Buy one seat of each assistant to test on, then watch whether members actually install and use the shared skills.
keep going if · In 3 of the first 4 prepaid teams, at least 3 members have a synced skill running within 7 days of payment, and 0 teams request a refund
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.
$150
per prospect, refundable
how · Prepaid first month through card checkout on the landing page - the right instrument here because this buyer already pays for Cursor and Claude seats by company card and self-serve checkout at this price is how they buy every tool; the founder pays, no signature needed, receipt names the team and the 14-day go-live date. set up: Stripe Checkout ↗
what it reserves · One of 10 founding-team slots, the $15 per seat price locked for 12 months, and a go-live date within 14 days of payment for up to 10 seats
refund · Full refund automatically if sync is not live for the third teammate within 14 days, and on request for any reason through day 30.
target · 5 prepaid teams from 20 calls plus 2 from the free-template funnel, 7 total within 21 days
Go: build it if
7 or more $150 prepays within 21 days (at least 5 of 20 from calls, a 25 percent close rate), and 3 of the first 4 delivered teams have 3+ members using synced skills within a week - build the sync product.
Kill: stop if
Fewer than 2 prepays after 20 calls, or 100+ template clones producing 0 paid conversions, or fewer than half of paying teams getting 3 members to install - the git repo plus README is good enough and this is a feature, not a company.

outreach message
Saw your team ships client work with Cursor and Claude, and I'd bet your best prompts live in a Notion doc nobody has opened since spring, so everyone's agent behaves a little differently. I'm building Packroom: one private skill library where your team proposes and reviews skills like pull requests, and approved versions sync into each member's Claude Code, Cursor and Copilot automatically. Founding teams get their top 10 prompts converted and synced within 14 days at $15 per member per month, locked for a year. Open to a 20-minute call this week?

deposit terms
Your $150 prepays your first month for up to 10 seats and reserves one of 10 founding-team slots at $15 per seat per month, locked for 12 months. We convert your top 10 prompt docs into versioned skills and turn on sync for your whole team within 14 days of payment. If sync is not live for your third teammate by day 14 you are refunded automatically, and you can request a full refund for any reason through day 30.

The concept in full
- What
- A private skill repository for 3 to 30 person teams: members propose skills, review diffs like pull requests, and approved versions propagate automatically into each person's Claude, Cursor or Copilot setup. It gives a team one source of truth for how their agents behave while each person keeps running their own assistant. In the first hour a user imports the team's scattered prompt docs, converts three into SKILL.md folders, and invites two colleagues who get them on next launch.
- Grounded in (2025-2026 signals)
- YC Requests for Startups, Fall 2026: 'Multiplayer AI'. Agent Skills open standard (December 18, 2025), about 40 supporting products by June 2026. n8n's October 2025 $180M Series C at $2.5 billion shows small teams pay to codify their own automation. Keyword coverage: 'agent builder' 4 companies in the last 2 years, thin.
- What it rides
- Rides the YC Fall 2026 RFS 'Multiplayer AI': collaboration between people who each run agents, applied to the skill layer where team knowledge actually lives.
- Why now
- By June 2026 about 40 products load the same skill format, so for the first time a mixed team on Claude, Cursor and Copilot can share one library; YC's current Fall 2026 batch explicitly requests 'Multiplayer AI' and the brief tracks only 4 recent 'agent builder' companies.
- Wedge: first customer and entry point
- First customer: a 5 person agency or startup where everyone pays for their own Cursor or Claude seat and prompts live in a Notion graveyard. Entry point: $15 per member per month, self-serve, starting with the founder who is tired of pasting prompts into Slack.
- Closest real companies, as the generator saw them
- Sim (yc X25) is a workspace that hosts and manages agents centrally; Packroom syncs versioned skills into assistants each member already runs. Altrina (yc W25) automates SOPs as a platform rather than distributing them as skills.
- Main risk
- Teams may keep sharing skills through the git repos they already use, and a repo plus a README may stay good enough.
