Your Marketplace Listings Are Not Your Marketplace Strategy

Why a platform only becomes a growth channel once it has a community, and what American Express understood that most builders miss

There is a comfortable story that gets told in Cloud GTM and in B2B marketplace planning generally. It goes like this: build marketplace, add the listings, publish it, and the channel starts working. In other words, if you build it, they will come. Revenue arrives because the storefront exists.

It almost never happens that way.

We see this pattern constantly at Digica. A company with a strong core product decides to build a marketplace alongside it. The logic is sound. A marketplace creates a new surface to be discovered on, it pulls in buyers earlier in their research, and it gives the core business a route to revenue that does not depend entirely on outbound sales or paid media. Good idea, correct instinct, real precedent behind it.

Then launch day arrives, the platform goes live, and very little happens.

The reason is almost never the product. It is that a marketplace is not a storefront you open. It is a community you have to start, and communities need a first push before they generate their own momentum. Until enough people are transacting to make the platform worth visiting, nobody has a reason to visit. That is the cold start problem, and no amount of build quality solves it.

Launch gives you a surface, not a snowball

Publishing your platform achieves one useful thing. It creates a place where a transaction can happen. Everything that turns that place into a growth channel gets built afterwards, and most of it has nothing to do with the product itself.

Here is what going live does not give you:

• A reason for a buyer to arrive when the results pages are still thin.

• A reason for a supplier to invest effort in a profile that almost nobody sees.

• A repeatable route by which marketplace activity feeds revenue back into your core business.

• Any organic search authority in a category where established players have a ten year head start.

Those four gaps are where marketplace maturity actually lives. A company with an average platform and disciplined answers to all four will outperform a company with a beautiful platform and no answers, every quarter, without exception.

The example worth studying: American Express did not build a directory and wait

American Express is a payments business. Its revenue comes from cardholder spending, annual fees and merchant fees. Restaurants are one of its largest cardmember spending categories, worth around $100 billion in volume in 2023.

So it did something that looks strange for a card issuer. It bought a restaurant reservation platform. Resy in 2019, then Tock in 2024 for a reported $400 million, plus Rooam for mobile payments and point of sale integration.

That is a two-sided marketplace sitting next to a core business that has nothing to do with hospitality software. Diners on one side, restaurants on the other, and a payments company owning the matching layer between them. Structurally, it is exactly what most of our clients are trying to build.

What matters is what happened next, because Amex did not simply own the platform and hope.

It brought its own demand. Amex already had millions of high spending cardholders. That is the asset most marketplace builders lack at launch, and Amex pointed it directly at the platform rather than treating the two as separate businesses.

It gave people a concrete reason to transact. A dining credit was attached to premium cards, giving cardholders between $100 and $400 to spend when they book through the platform and pay with their Amex card. In the three weeks after the Platinum version launched, reservations from Platinum members rose 36%, their spending during that period increased 1.6 times, and the daily average number of Platinum members linking their card to a Resy account jumped fivefold.

Supply followed demand, not the other way round. The company has been explicit that the demand created by the dining credit is what accelerated restaurant sign-ups. Restaurants join because a premium, high spending audience is already there. Between the Resy acquisition in 2019 and the end of 2023, Amex reported a threefold increase in engaged diners and a 5.4 times increase in restaurants on the platform.

The loop closes back into the core product. Every reservation is a prompt to use the card. The marketplace does not need to be a large standalone profit center to be worth owning, because its job is to generate spending on the product that already makes the money.

Read those four moves again, because they are the whole playbook. Bring demand you already control. Manufacture a reason to act. Let supply chase the audience. Design the loop back to the core business from day one.

Most marketplace launches do the opposite. They recruit suppliers first, publish, and then hope buyers appear. That sequence puts the burden of patience on the people least willing to be patient.

The uncomfortable truth about supply-first launches

There is a version of this argument that says you cannot sell to buyers until you have suppliers, so supply must come first. That is half right. You do need enough supply for a search to return something credible. What you do not need is breadth.

The rule we work to: depth in a small number of categories beats coverage across many. A buyer who searches your platform and finds three genuinely qualified providers in their exact niche has a good experience. A buyer who finds one thin profile in each of forty categories concludes the platform does not work, and that conclusion is very hard to reverse.

Empty results pages destroy trust faster than missing categories do. Trust is the actual product a marketplace sells. Buyers and suppliers are not paying for software, they are paying for the promise that the platform surfaces quality, remains neutral, and is worth their attention.

So the sequence that works looks like this. Concentrate supply narrowly enough that it looks deep. Bring in demand you can control or buy. Prove match quality on a small number of real transactions. Only then widen the categories and spend on scale.

What has to be true for the snowball to start

Momentum in a marketplace is not a mood. It comes from a small number of specific things being in place.

Someone owns demand as a job. Not as a launch campaign, as a permanent function. A marketplace is a matching layer, not a discovery engine. Buyer attention has to be created somewhere else and routed in. If nobody's targets depend on that, it will not happen consistently.

There is a reason to show up that is not the transaction. Amex used a spending credit. Other platforms use rankings, awards, benchmarks, data, community recognition or editorial. People need a reason to visit on a day when they are not ready to buy, because that habit is what makes the platform present when they finally are.

The search surface is being built continuously. Category pages, comparison pages, buyer guides, RFP templates and supplier profiles are how a marketplace earns organic traffic in the long term. Marketplace SEO is slow and unglamorous, and it compounds, which is a rare combination in growth. Buyers now research with search engines and AI assistants long before they reach any platform, so the content that answers those research queries is where discovery actually begins.

Match quality is measured, not assumed. One good match creates a repeat buyer. Three bad ones teach the market that your platform does not work. Track acceptance and downstream conversion rather than inquiry volume, because inquiry volume is the metric that flatters you right up until churn arrives.

The loop back to the core business is instrumented. If you cannot show how marketplace activity produced revenue in the main product, the platform will lose its budget in the second planning cycle regardless of how well it is performing.

For AI marketplaces, where supply can go stale within months, the sequence matters even more. See GTM strategy for AI marketplaces.

A diagnostic for a marketplace that is not working

If you are a year past launch and the numbers are disappointing, work through these in order. The answers usually cluster around two or three of them.

1. Search your own platform as a buyer would. If any category you actively promote returns thin or empty results, fix supply depth before spending another euro on traffic.

2. Where does buyer awareness come from before they arrive? If nobody can name the sources, demand is your bottleneck and everything else is a distraction.

3. Whose target depends on marketplace demand? If the answer is nobody, you have an ownership problem rather than a strategy problem.

4. What is the reason to visit when not buying? If there isn't one, you are paying to reacquire the same audience every time.

5. Are your suppliers getting value they can see? Leads, visibility, data, credibility. Suppliers who cannot see a return quietly stop updating their profiles, and stale supply reads as a dead platform.

6. Can you trace marketplace activity to core product revenue? If not, build that measurement now, before someone senior asks.

7. Is the platform ranking for anything commercial? If your organic visibility is limited to your own brand name, the discovery layer has not been built yet.

The point

A marketplace does not become a growth channel because you published it. It becomes one when enough people are moving through it that their activity attracts more activity, and that first push has to be engineered deliberately by someone whose job it is.

American Express understood that a booking platform is worthless without diners, so it brought the diners, gave them a reason to book, and let the restaurants follow. The mechanics translate cleanly to a B2B marketplace in any vertical. Bring the demand you already have, create a reason to arrive, prove the match, and build the discovery layer that keeps buyers coming after the launch budget is spent.

If your marketplace is not producing the numbers you modelled, the first question is rarely about the platform. It is about who owns the community.

FAQ

Why do most marketplace launches fail to generate revenue?

A marketplace is a community that needs a first push, not a storefront you open. Until enough people transact to make the platform worth visiting, nobody has a reason to visit, which is the cold start problem.

What did American Express do with Resy and Tock?

Amex bought Resy in 2019 and Tock in 2024, then pointed its cardholders at the platform with a $100 to $400 dining credit on premium cards. The demand accelerated restaurant sign-ups, and every reservation became a prompt to use the card.

Should a marketplace launch with breadth or depth of supply?

Depth in a small number of categories beats coverage across many. A buyer who finds three qualified providers in their niche has a good experience, while one thin profile in each of forty categories signals the platform does not work.

What has to be true for marketplace momentum to start?

Someone owns demand as a permanent job, there is a reason to visit beyond the transaction, the search surface is built continuously, match quality is measured, and the loop back to the core business is instrumented.

How do you diagnose a marketplace that is not working a year after launch?

Search your own platform as a buyer, identify where buyer awareness comes from, and check whose target depends on marketplace demand. Then check the reason to visit, visible supplier value, traceability to core revenue, and commercial organic rankings.
