GMV, take rate, and two-sided growth.

Plan buyer and seller growth together, with GMV, take rate and commissions, and the match rate that shows whether the two sides are in balance.

Startup Suite is an AI planning workspace that helps marketplace founders model GMV, take rate, liquidity, and two-sided growth from one model.

This page is for marketplace and platform founders modelling GMV, take rate, and liquidity.

Why two-sided growth is hard to plan

Demand and supply grow at different speeds

Grow demand too fast and supply can't keep up, or the reverse, and liquidity stalls.

Liquidity is fragile

Most plans don't track how many listings or requests end in a transaction, so a falling match rate shows up late.

Take-rate trade-offs are murky

Raise the take rate and you risk supply; lower it and you starve revenue.

Marketplace planning workspace showing supply, demand, GMV, take rate, liquidity, and scenario modelling.

Two sides, one set of numbers

Buyers and sellers in one model, with the match rate between them.

GMV only grows when buyers and sellers grow together. This model tracks both sides and the share of listings that turn into a transaction.

Network calls you can model first

Subsidy, pricing and launch-market calls, each tested on both sides of the market at once.

Which side to subsidise
Compare subsidising buyers or sellers, and see each subsidy's cost against the GMV it adds.
Where to set the take rate
See how each take-rate step changes net revenue and seller numbers.
Where to seed supply
Start supply in the one city or category where buyer demand is densest.

What the marketplace model covers

GMV & take rate

Build gross merchandise value and net revenue from take rate and commissions.

Two-sided growth

Model buyers and sellers together, and what happens when one side lags.

Liquidity & match rate

Track the share of listings or requests that end in a transaction, on each side.

Contribution per side

See the cost to acquire and serve each side, and the net contribution.

From both sides of the market to net revenue

  1. Step 1

    Set both sides

    Buyer and seller acquisition, retention, and activity.

  2. Step 2

    Model GMV

    Transactions and basket size roll into GMV.

  3. Step 3

    Apply take rate

    Commissions and fees turn GMV into net revenue.

  4. Step 4

    Balance the network

    Test subsidies and incentives on liquidity and contribution.

Marketplace modelling questions

Do you model GMV and take rate?

It's designed to. GMV comes from both sides of the network, and take rate plus commissions turn it into net revenue.

Can it handle two-sided growth and liquidity?

It's built to. Buyer and seller growth, match rate and contribution per side are modelled together.

What is a marketplace financial model?

It builds GMV from both sides of the network, applies take rate and commissions to get net revenue, and models liquidity and contribution for buyers and sellers separately.

Is this just a spreadsheet template?

No. A template usually grows GMV as one line. Here buyers and sellers are separate inputs, so raising the take rate shows its effect on seller numbers and fill rate as well as revenue.

What outputs does it produce?

It's built to produce a GMV and take-rate model, a liquidity and contribution model, and a three-scenario comparison (base, higher take rate, slower demand growth). Each figure traces to an assumption.
