Growth Rate Benchmarks Investors Actually Use — And What They Mean for Marketplace Founders

Lenny Rachitsky surveyed two dozen top-tier investors to establish what 'good' and 'great' growth rates look like at each stage of a business. The consensus: early MoM percentages are largely meaningless at small scale. For B2B, the real benchmark is time-to-$1M ARR after launch — good is 12 months, great is 9. For consumer, engagement and retention matter more than revenue in the early stage.

Most founders — including marketplace founders — benchmark themselves against percentage growth metrics that investors don't actually weight heavily at early stages. The deeper signal here is that investors are looking for evidence of compounding demand, not just absolute growth. This distinction matters because marketplaces have a structural lag: you must build supply and demand simultaneously before monetization even kicks in. Founders who are still learning how to build a marketplace often discover this lag can make early revenue numbers look weak even when the underlying mechanics are healthy. Founders who don't understand what investors are actually measuring will either over-optimize for the wrong metrics or misread their own progress.

Supply & Demand: Marketplace founders often delay meaningful revenue because they're still solving the chicken-and-egg problem. That's legitimate — but it means the clock on investor expectations starts later. Be deliberate about when you declare 'launch.' Reviewing a marketplace launch strategy guide before going live can help you avoid declaring launch too early. An unmonetized marketplace with strong supply-demand matching and repeat usage is a stronger signal than weak GMV from a half-built market.

Liquidity: Liquidity — the rate at which a buyer finds a match — is the marketplace equivalent of DAU/MAU for consumer products. Investors in consumer want >50% D30 retention. In marketplace terms, this translates to: are buyers returning to transact again within 30 days? Are suppliers getting consistent order flow? If yes, you have a liquidity signal worth showing.

Trust: Retention is the trust proxy. A marketplace where both sides return is a marketplace where trust is working. Cohorted retention — tracking whether a buyer's second and third transactions happen and grow — is the data that proves trust is compounding, not just present at first use.

Growth: The $500K to $5M ARR velocity matters more than 0 to $1M velocity. For marketplaces, this maps to the period after you've solved liquidity and are scaling proven transaction pairs. Don't burn credibility trying to show fast early growth if your liquidity fundamentals aren't solid yet.

Onboarding: The moment you 'go live' starts the investor clock. For marketplaces, going live before supply density is sufficient is a common mistake — it creates a poor demand experience, kills early retention, and produces bad data that's hard to recover from. 'No data is better than bad data' is especially true in marketplaces.

Monetization: Early-stage investors don't need to see strong monetization — they need to see strong signals that monetization will work. In marketplaces, this means showing high repeat transaction rates, growing basket sizes, and low CAC relative to transaction volume. These are leading indicators of a take-rate business that will compound.
