Checklist: Marketplaces — AI Startup Funding

A marketplace is ready to raise when it has proven liquidity in one focused niche, can show a stable take rate and repeat usage on both sides, and knows what it cost to get there. This checklist covers the metrics marketplace investors examine first.

How to use this checklist

This checklist suits two-sided marketplaces for goods, services or B2B trade that use AI for matching, pricing or trust.

Work through each list before you contact investors. Anything you cannot tick is either a task to finish or a risk to explain openly in your pitch.

1. Company and legal basics

These apply to every company raising money, but gaps here slow rounds more than almost anything else.

  • Up-to-date cap table showing every shareholder, option and convertible.
  • Signed IP assignments from all founders, staff and contractors.
  • Articles of association and any shareholder agreement to hand.
  • SEIS or EIS advance assurance applied for, if you are raising from UK angels.
  • Company filings at Companies House up to date.

2. Marketplace proof points

The evidence investors in this sector look for first.

  • Match rate: share of listings or requests that complete.
  • Time to match and repeat rate for each side.
  • Take rate and why users accept it.
  • Evidence that transactions stay on the platform.

3. Numbers and financial model

Your model should show how the money you raise gets you to the next milestone.

  • Cost to reach liquidity in the first niche.
  • Acquisition cost for each side.
  • Subsidies and when they stop.
  • Payments, trust and support costs per transaction.

4. Data room documents

Have these organised in one shared folder before the first meeting.

  • Transaction data by month and cohort.
  • Terms of service and payment arrangements.
  • Fraud and dispute records.
  • Expansion plan for the next niche.

5. Pitch and investor readiness

Readiness is also about how you run the process.

  • A short deck that states the problem, customer, traction and ask in the first few slides.
  • A clear amount to raise and a list of what it pays for.
  • A target list of investors who back your sector and stage.
  • A one-paragraph answer to 'why now?'.

Red flags to fix before you pitch

Investors often stop at these issues:

  • Many listings, few transactions.
  • Take rate falling as you grow.
  • Repeat pairs disappearing off-platform.
  • Nationwide launch with no liquid niche.

Questions to prepare before you pitch

  • What share of listings complete?
  • Which side is harder to win?
  • How do we stop off-platform deals?
  • What will the next niche cost?
