Guildhall
The exchange where enterprises hire proven AI agents like contractors.
Guildhall is a self-serve marketplace where enterprises browse, trial, and deploy third-party AI agents - sales research agents, ops agents, finance-close agents - each listed with standardized, independently run performance telemetry instead of vendor claims.

The idea in full
- What
- Guildhall is a self-serve marketplace where enterprises browse, trial, and deploy third-party AI agents - sales research agents, ops agents, finance-close agents - each listed with standardized, independently run performance telemetry instead of vendor claims. Builders connect their agents through Guildhall's no-code integration layer; the company runs the evals, handles the security and data-handling attestations enterprise procurement requires, and takes a cut of every agent-hour sold. It creates a category that does not exist yet: an agent labor exchange, priced like contract labor rather than per-seat software.
- Why now
- The 2024 cohort alone added 81 agent companies to this cluster and YC's Fall 2026 RFS names Multiplayer AI as a theme, yet there is no distribution or trust layer between builders and buyers; the graveyard shows why one is needed - Solari AI, which promised agents that work right out of the box, died in 2024 with no way to prove that claim.
- Wedge: first customer and entry point
- One agent category - sales research agents - benchmarked on a public leaderboard that builders like the current YC crop submit to for distribution; the leaderboard is the free product, the marketplace is the monetization.
- Path to 100x
- Enterprise spend on the tasks these agents replace sits in the $10-100B contract-labor and outsourcing band, and a marketplace taking 15-20% of agent-hours captures it with software margins. Two-sided liquidity is the winner-takes-most mechanism: builders list where buyers are, buyers trust the exchange with the deepest telemetry history, and that eval dataset cannot be replicated by a late entrant.
- Ceiling
- If enterprises standardize on one or two agent vendors per function instead of a rotating bench, take-rate volume stays too thin to clear a $1B outcome.
- Closest real companies, as the generator saw them
- Dock builds a workspace for running your own agents, not a market for hiring others'; Tasklet and Cohesive AI are single-vendor agent products that would list on Guildhall rather than compete with it; OpenTag is a model-routing tool without a marketplace.
- Main risk
- Model platforms bundle agent distribution into their own stores, and builders list there instead because that is where the models already live.
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
Capital-light exchange on $10-100B of contract labor where the accumulated eval telemetry is a moat a late entrant cannot replicate.
Bootstrapper
3/5
Software margins and self-serve listing are affordable, but two-sided liquidity plus enterprise security attestations delays real take-rate revenue.
Operator
2/5
Enterprises do not yet have a line item for hiring agents by the hour, and a leaderboard gives procurement nothing to sign.
Technologist
2/5
Standardized evals and a no-code connector layer are light engineering, and model platforms bundling their own agent stores absorb it directly.
Risk
2/5
Model platforms bundling their own agent stores can starve the exchange of supply, and Solari AI already died proving agent claims.
trends
3/5
Multiplayer AI RFS and the 2024-2025 vendor flood create a real trust gap, but the exchange has no forcing event beyond cohort volume.

Subroclaim
Agents that negotiate insurer-to-insurer claim recoveries on both sides of the file.
Subroclaim runs subrogation and inter-carrier recovery as an agent service for US property and casualty insurers: the agent reads the loss file, builds the demand with liability evidence, and then negotiates directly with the other carrier's Subroclaim agent, escalating to a human adjuster only on disputed liability or amounts above a set threshold.

Piecework
A marketplace where enterprises hire third-party AI agents and pay per verified task.
Independent builders list agents with a declared task type, a price per completed unit and a verification rule; enterprise teams connect their systems through no-code connectors and buy agent labour without a procurement cycle.

Procura
API that gives any AI agent legally binding authority to act for a small business.
Procura is the mandate layer agent builders call before their agent signs, pays or files anything: the small business owner verifies identity once, grants a scoped, revocable power of attorney, and Procura issues a cryptographic credential that binds each agent action to that mandate with a qualified electronic seal and an immutable audit trail.
