AI for the supply-and-demand decisions marketplaces face

Liquidity bets, take-rate strategy, supply vs demand prioritization, vertical vs horizontal expansion. A boardroom built for businesses where balance is the whole product.

Start Free See How It Works

What you get

Frames the supply vs demand call

Which side do you over-subsidize this quarter? The Growth Hacker and Customer synths surface what the dashboards miss about liquidity.

Stress-tests take-rate strategy

Higher take-rate now, or lower take-rate to compound supply? The CFO and Strategist debate the long-term unit economics against the short-term P&L.

Pressure-tests geographic & vertical expansion

Same city, deeper supply? Next city? Or pivot to a vertical-specific marketplace? The Operator and Strategist work the sequencing.

Frames the platform vs aggregator vs marketplace identity

Are you a marketplace, a SaaS for one side, or an aggregator? The Strategist forces the positioning into the open.

Questions people ask

Real questions. Multiple expert perspectives. Every time.

“Should we raise our take-rate from 12% to 15% now, or wait until supply density is stronger?”

“Do we over-subsidize supply or demand in our next city launch?”

“Should we pivot from horizontal marketplace to a vertical-specific one?”

“When do we add a SaaS layer for our top-tier supply?”

“Should we ban our largest supplier who keeps undercutting on price?”

“How do we price a "promoted listing" without breaking trust on the buyer side?”

Key Recommendations

Take-rate increases trigger supplier exodus before they trigger margin gain
Supply density drives demand-side conversion more than any promotion
New-city launches need the subsidy to hit the liquidity floor
Re-evaluate take-rate at 60% supply utilization, not on a calendar

Synthesized Recommendation

Hold take-rate at 12% for two more quarters. Use the margin headroom to subsidize supply in your next three cities — liquidity compounds, take-rate increases don't once trust erodes.

Full analysis continues with detailed reasoning, trade-offs, and next steps...

Watch Out For

The board will pull for the take-rate move — be ready with the LTV argument
Subsidies become structural — set the sunset trigger before launching

Expert Opinions

The Growth Hacker
“Every marketplace founder thinks the answer is "more demand." Almost always it's supply density. A boardroom is where you stop optimizing the wrong side and admit which constraint is actually binding.”
The Growth Hacker — Scrappy growthOn marketplace liquidity

Why SynthBoard for this

Built for two-sided economics

The Growth Hacker, Customer, and Data Scientist synths reason about the liquidity, density, and matching dynamics marketplace founders actually live with.

Decisions framed as supply vs demand

Most decisions in a marketplace are really a supply-or-demand prioritization in disguise. SynthBoard surfaces which it is — and which side you're neglecting.

The skeptic against the easy growth story

Marketplaces love GMV. The Skeptic and Devil's Advocate are wired to challenge the GMV-without-margin growth that kills the business 18 months later.

Re-runnable as the marketplace matures

Take-rate, subsidy, and expansion decisions get re-asked every six months. Save the session, re-run with new data, track how the answer shifts.

Common questions

The questions people ask before they sign up.

Does SynthBoard work for vertical marketplaces or only horizontal ones?

Both. Vertical marketplaces benefit from the Strategist and Customer synths who reason about the specific industry. Horizontal marketplaces lean more on the Growth Hacker and Operator. The boardroom adapts to the motion you describe.

How does it handle the chicken-and-egg liquidity problem?

It runs the supply-vs-demand prioritization explicitly. The Growth Hacker will argue for supply-first; the Customer synth will surface what the demand side actually needs to convert. You get the trade-off forced into the open.

Is this useful for B2B marketplaces or only consumer?

Both — the metrics shift. B2B marketplaces lean on the Sales Leader, CFO, and Strategist (relationship sales). Consumer marketplaces lean on the Growth Hacker, Customer, and Marketer (volume sales). Same boardroom, different lineup.

Can it model the impact of a take-rate change on supply churn?

It reasons about the strategic shape of the trade-off — what take-rate increases historically cost in supplier retention, how to phase the change, what to bundle alongside. It won't simulate your specific dataset; it will pressure-test your hypothesis.

How does this compare to hiring a marketplace consultant?

A marketplace consultant gives you one expert's playbook for $10K-30K. SynthBoard runs five experts who openly disagree, in 10 minutes, for under a dollar. Use a consultant for ongoing operational ownership; use SynthBoard for the high-stakes calls in between.

Will it work pre-launch, or only for marketplaces with existing data?

Pre-launch is a high-value use case. The boardroom pressure-tests your liquidity hypothesis, your take-rate assumption, your launch-city choice — all the bets you have to make before there's any data to lean on.
