Rent a Stadium: The Surprisingly Scrappy Way to Solve the Marketplace Chicken-and-Egg Problem
In a marketplace, should you solve supply or demand first?
Gojek needed 60,000 drivers. So they rented a stadium and hired them all in a few weeks. Lyft built a team of hundreds of account executives whose only job was to pick up the phone and call potential drivers. These are not elegant growth loops. They are brute-force solutions to what sounds like an elegant problem.
The chicken-and-egg problem in marketplaces -- you need supply to attract demand, but you need demand to attract supply -- has been theorized to death. In practice, the companies that solved it did something far less theoretical: they picked a side, got scrappy, and worried about scalability later. The academic elegance of marketplace theory contrasts sharply with the brute-force reality of marketplace building. The founders who succeed are the ones who stop looking for a clever solution and start doing the unscalable work.
You are launching a marketplace. You have neither supply nor demand. Which side do you solve first, and how do you avoid the death spiral where each side waits for the other? Four marketplace builders who have collectively solved this problem at Lyft, Gojek, Eventbrite, Patreon, and Thumbtack share their approaches -- and while they mostly agree on supply-first, the nuances in their reasoning reveal strategies that most marketplace theory overlooks.
The 4 Positions
Evidence from the Archive
Lyft: hundreds of account executives phone-calling drivers to onboard them, reaching 1% of U.S. workers
Thumbtack 'smoke machine' filter: customers checked 'DJ with smoke machine' not realizing it eliminated 95% of supply
Twitch/Kai Cenat Union Square incident: demonstrated raw power of creator-fan connection at scale
Hailo in London: when riders opened the app and no cars were available, the entire value proposition collapsed
Gojek stadium hiring: rented a stadium to hire 60,000 drivers in weeks, solving supply constraint in one bold move
Gojek super app: each vertical (rides, food, payments) required different supply-side strategies
Airbnb: guests who become hosts after experiencing the platform as travelers
Eventbrite: attendees becoming event creators, systematically amplified by the growth team
The Synthesis
"Supply first" is correct as a starting point but incomplete as a strategy. The full sequence is: (1) solve supply with whatever scrappy tactics work -- stadiums, phone calls, manual curation, (2) focus relentlessly on supply quality, not just quantity, because fill rate is the metric that determines whether demand sticks, (3) once the marketplace is functioning, look for demand-to-supply conversion loops that create compounding growth, and (4) use retention as a diagnostic, not a goal, to find and fix leaks on both sides.
The chicken-and-egg problem is usually a phase, not a permanent condition. Most successful marketplaces solved it within months through unscalable tactics, then graduated to scalable growth loops. Teams that stay stuck are the ones looking for an elegant solution to a problem that requires an inelegant one.
Lyft's hundreds of account executives calling drivers seemed wasteful, but the drivers they onboarded were dramatically better, which improved fill rate, which improved the rider experience, which drove organic demand. Fill rate is the metric that determines whether demand sticks, not supply volume.
The emotional dimension of supply matters more than marketplace theory acknowledges. Some suppliers do not want to optimize. These are not rational economic behaviors -- they are human behaviors that rational models fail to capture. The best marketplace builders understand their supply-side users are people with complex motivations, not economic maximizers.

The Bottom Line
Retention benchmarks from Lenny's newsletter on consumer businesses provide the measurement framework for both sides of the marketplace. If your supply-side retention curve flattens above 30% at month 12, you likely have adequate supply quality. If your demand-side retention flattens above 25%, your matching algorithm is working. If either side shows a continuously declining curve with no flattening, you have a fundamental product-market fit problem that no amount of acquisition spending will solve.
The third insight, from Camille Hearst, is that the emotional dimension of supply matters more than marketplace theory acknowledges. Lauzier warns against giving users too much control. Hearst warns that some suppliers do not want to optimize. These are not rational economic behaviors -- they are human behaviors that rational marketplace models fail to capture. The best marketplace builders understand that their supply-side users are not economic maximizers. They are people with complex motivations, emotional attachments to their work, and resistance to being reduced to marketplace metrics.
