Score = 100 x cbrt(Trend x Demand x 100x) x (1 - 0.5 x crowding) + government bonus (max 5), calibrated so the 95th-percentile idea scores 90 (order never changes).

Percentiles are among the 272 ideas in the catalog; the terms matched were no-code, readable, transactable, smb, connects, booking, inventory, payment.
The idea in full
- What
- An SMB connects its booking, inventory, and payment tools (Shopify, Square, Calendly, QuickBooks) in a no-code dashboard, and Openstall publishes them as one hosted, self-maintaining endpoint that any AI agent can query and transact against. Merchants pay a monthly subscription; agent developers build on the unified catalog for free, which is what makes it a platform rather than a widget. Founder-led sales start with franchise groups and booking-heavy verticals, then the catalog itself becomes the sales pitch.
- Why now
- YC's Fall 2026 RFS names Self-Maintaining APIs, and S26 companies like Rindler (the translation layer between AI agents and the web) and Context.dev prove agents are hitting the open web now; yet of 297 cluster companies from the last two years, almost all sell to agent builders, leaving the merchant side of the pipe unserved.
- Wedge: first customer and entry point
- Sign 50 appointment-based businesses (salons, dental, repair shops) in one metro through a franchise operator, expose their calendars and payment links as agent endpoints, and let one consumer assistant complete real bookings end to end.
- Path to 100x
- SMB commerce enablement is a $100B+ market, and if agent-mediated purchasing becomes even a single-digit share of SMB transactions, the registry holding the merchant endpoints becomes winner-takes-most the way payment networks did, because agent frameworks standardize on the deepest catalog. Revenue expands from subscriptions to a per-transaction take once agents route real purchase volume through the endpoints.
- Ceiling
- If the big commerce platforms open native agent access, Openstall is squeezed into the long tail of unplatformed businesses, a real but much smaller pool.
- Closest real companies, as the generator saw them
- Rindler and Context.dev translate the existing web for agents from the developer side; Executor manages integrations for AI builders. Openstall sells to the merchant, owns the SMB relationship, and publishes structured endpoints instead of scraping around their absence.
- Main risk
- Shopify, Square, and Google ship native agent endpoints for their own merchants before Openstall reaches catalog scale.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Merchant-side registry in a $100B+ flow with payment-network dynamics, though Shopify and Square shipping native endpoints is a live squeeze.
Bootstrapper
2/5
Merchants do not currently pay anyone for agent endpoints, so it is net-new spend with Square and Shopify able to ship it free.
Operator
2/5
Merchants feel no pain today from being unreadable to agents, so the subscription is a bet on demand that has not arrived.
Technologist
2/5
No-code connector layer over Shopify, Square and Calendly APIs is weekend-copyable, and those same platform owners can ship native agent endpoints in one release.
Risk
2/5
The whole endpoint depends on Shopify, Square and QuickBooks tolerating it, and each of them can ship native merchant agent access first.
trends
2/5
The brief shows Stripe's suite already live on Wix, WooCommerce and BigCommerce and UCP co-built with Shopify - the feared incumbents shipped first.
