What marketplace investors actually back
A marketplace connects two sides of a transaction and takes a cut of what moves through it. That covers more ground than most founders expect. Airbnb, Etsy, DoorDash and Faire are all marketplaces, and so is every vertical software company that bolted on payments and started clipping a percentage of each order. Investors who follow this category are buying one idea: if you own the transaction, you own the relationship, and revenue grows without you carrying inventory.
That's why marketplace investors behave differently from generalist consumer or software backers. They know where the model breaks. Supply is usually harder to get than demand. Liquidity in one city tells you almost nothing about liquidity in the next one. And the take rate you can defend at scale is often lower than the one you're charging today. Someone who has lived through those problems will ask about them in the first meeting. A generalist will ask about your growth rate and miss the thing that actually kills marketplaces.
The overlap with neighboring categories is heavy. Many of the same people also appear under e-commerce investors and consumer internet investors, because a marketplace is usually both at once. If you hold inventory, manage supply directly or handle fulfillment yourself, those two lists are worth working through alongside this one.
Why marketplace investors are still writing checks
The underlying trend hasn't reversed. E-commerce accounted for 16.9% of total US retail sales in the first quarter of 2026, and online sales grew 9.8% year over year while total retail sales grew 3.9%, according to the US Census Bureau. Online is still taking share from offline, and marketplaces are one of the main ways that share moves.
The sharper signal for founders is how much of that volume runs through third parties rather than through the platform itself. In the second quarter of 2026, third-party sellers accounted for 61% of worldwide paid units sold on Amazon. Amazon's third-party seller services brought in $46.8 billion in that quarter alone, up 16% year over year, per the company's own earnings release. The largest retailer in the world makes most of its unit volume from other people's inventory. That is the marketplace thesis in a single number, and it's why investors keep funding versions of it in categories Amazon doesn't reach.
Where marketplace investors are based
Just over half of the marketplace investors in Angel Match are in the United States, with 5,500+ tagged to the country. The United Kingdom is next with 800+, then Germany with 400+, India with 350+, France with 250+ and Canada with 200+. Brazil, Singapore, the Netherlands and Australia each carry a smaller but real group. That spread matters more here than in most categories. Marketplace models travel across borders better than almost anything else, and investors in each of those markets have usually watched a local version of your playbook run to either liquidity or collapse.
Inside the US, California leads with 2,000+ and New York follows with 1,000+. England on its own carries 650+, which is more than any US state except those two. Massachusetts, Texas, Illinois, Florida and Washington each land in the low hundreds.
At the city level the concentration gets sharper. San Francisco has 1,000+ marketplace investors and New York City has 950+, and between them those two cities account for roughly a fifth of the entire category. London is third with 500+, then Los Angeles, Boston, Paris, Chicago and Berlin. The practical read is simple. If you're building a marketplace anywhere in the world, you'll end up pitching people in the Bay Area and New York eventually. But the London, Paris and Berlin groups are deep enough that a European founder doesn't need to get on a plane to close a first round.
What stage marketplace investors fund
Most of this list is early. Seed is the largest stage tag by a wide margin, with 4,500+ marketplace investors marked for it, and that pool overlaps heavily with the general seed investor list. Early stage venture follows with 2,000+, pre-seed with 1,500+, Series A with 1,000+ and Series B with 750+. Late stage venture barely registers at all. If you're raising a Series C for a marketplace, this isn't the list you want.
That shape lines up with how marketplaces get funded in practice. Early rounds are relatively cheap to justify, because the only thing you have to prove is that one small pocket of supply and demand can clear. Later rounds get expensive, because now you have to prove the same thing again in a second and third market against a competitor who has read the same playbook. So the money clusters where the risk is legible and the check is small.
By investor type, venture capitalists are the biggest group at 6,000+, followed by angel investors at 5,500+ and private equity investors at 4,500+. Micro VC is smaller at 800+ but worth real attention, because small funds are often the ones willing to write a first check into a single-city marketplace before a second city exists. Keep in mind that individual investors carry several type tags at once, so these groups overlap rather than dividing the list into neat slices.
The numbers marketplace investors ask about first
Marketplace investors have a standard set of questions and they tend to ask them in a standard order. Knowing that order saves you a lot of wasted deck space.
The first is liquidity, not growth. What share of listings or requests turn into a completed transaction, and how fast? A marketplace with 10,000 listings and a 4% fill rate is in worse shape than one with 500 listings and a 40% fill rate, and anyone who has funded this category knows it. Lead with the fill rate or match rate for your strongest cohort, even if that cohort is a single neighborhood.
The second is take rate and whether it survives contact with a competitor. Say what you charge, say what the offline alternative costs and say why sellers stay when someone undercuts you. Take rates above 20% usually draw questions about seller churn. Take rates below 5% draw questions about whether you can ever cover payments and support costs.
The third is repeat behavior. Marketplaces live or die on whether buyers come back without paid reacquisition, so bring cohort data showing second and third purchase rates by month rather than a single blended number. If you want a defensible figure to sit next to that curve, work the math on one real cohort with an LTV calculator and show your inputs, not just the output.
The fourth is leakage. Every marketplace with high-value repeat transactions eventually loses pairs who meet on the platform and then transact off it. Investors will ask, and the answer they want is not "that doesn't happen here." It's a number, plus the specific reason people stay: payments protection, insurance, scheduling, dispute handling or financing. Pick the one that's genuinely true for your model and show it working.
How to approach marketplace investors
Because this category skews early and clusters in a handful of cities, your list will be longer and more geographically scattered than a founder in a narrow B2B niche would build. Marketplace pitches also get pattern-matched faster than almost anything else. Someone who has seen forty two-sided platform decks will decide in your first paragraph whether you're a new category or a rerun of one they already passed on.
So open with the pocket, not the vision. "We're the marketplace for X" is the rerun opening. "Restaurants in Queens rent equipment from each other about 1,400 times a month and we take 12% of it" is not. Name the exact supply you've secured, the exact demand you match it to and the transaction volume you're already clearing, even when that volume is small. Small and real beats large and hypothetical in this category every single time.
Volume of outreach matters too. With 10,000+ investors carrying this tag, a serious marketplace raise usually means a working list of 100 to 200 names and the discipline to run them across six to eight weeks instead of emailing everyone in week one. Track which threads got opened and which got replies, whether you do that in a spreadsheet or with email outreach built for it, because the second follow-up is where most marketplace intros actually turn into meetings.
One timing note specific to this category. Marketplace investors want to see a transaction number that moved between your first meeting and your second, so time your raise to overlap with a stretch where volume is climbing for a reason you can explain. If your marketplace is seasonal, raising into the trough costs you the single most persuasive slide you own.
Building your marketplace investor list
Start narrow. Filter the 10,000+ marketplace investors down to the stage you're actually raising and the two or three cities where your supply story reads best, then work that shorter list properly instead of emailing the whole category. The investor database lets you stack the marketplace tag against stage and location, so you can see who has already funded two-sided businesses at roughly your size. That's a better use of a week than another round of cold intros.
