Quick Answer
An app marketplace is the store a host platform runs so its users can find and install third-party apps, and most of them check for traction before they help you. Slack will not accept an app used on fewer than 10 active workspaces, Built for Shopify needs 50 net installs from paid shops and five reviews, and Zapier's Silver partner tier starts at 50 active users. List once you clear the store's gate, and build first customers elsewhere.
The advice arrives the moment you build on someone else's platform. List it in the marketplace, because that's free distribution.
It sounds rational. The store has search, the platform has trust, and the listing often costs nothing to submit. If your first customers came from old colleagues and that list has run dry, a store full of buyers looks like the next channel.
The stores' own developer documentation tells a colder story. This covers the five published gates that decide when a listing starts working, what the review queues cost in time, and what to build before you submit.
Five App Marketplace Gates That Check for Traction First
Each app marketplace below publishes a rule that ties listing, ranking or promotion to usage you already have. None of them sells you the first customer; each checks that you found some without it.
For every gate you'll get what the rule says, how it works, what to do about it, how to tell you've cleared it, and the usual mistake. The figures come from each store's current developer documentation, which changes, so check the linked page before you plan around a number.
1. Slack Marketplace Will Not List an App Nobody Uses Yet
The Slack Marketplace has a listing gate, not a promotion gate. Slack's guide to distributing your app in the Slack Marketplace says it is not currently accepting apps installed on fewer than 10 active workspaces with fewer than 10 weekly active users.
"Active" has a definition. The workspace has to have been used in the past 28 days, and sandboxes don't count, so ten test workspaces you created yourself will not get you in.
The check continues after approval. Slack's own wording is blunt: "If your app is published in the Slack Marketplace but it is not being used, we will reach out to you to learn more about your plans for the app."
So the work comes before the submission. Find ten real teams with the problem your app solves, get them using it weekly, and treat that as the first milestone rather than the listing. You've cleared the gate when your own install data shows ten outside workspaces active in the last 28 days.
The mistake is building the Slack app first and recruiting users second. That order puts you in front of a closed door with nothing to show the reviewer.
2. Built for Shopify Starts at 50 Paid Installs and Five Reviews
Getting listed on the Shopify App Store is a review of the app itself, which is why founders miss where the traction gate sits. It sits one step later, at Built for Shopify, the status that decides how prominently a listing is shown.
Shopify's Built for Shopify requirements set three merchant-utility thresholds: at least 50 net installs from active shops on paid plans, at least five reviews, and a minimum recent app rating. Shopify doesn't publish the rating number, so aim for consistently strong ratings rather than a figure.
Picture a reporting app with 30 installs, half of them on development stores. It's listed and searchable, and it's nowhere near the status. Every one of those 50 installs has to come from a real merchant paying for Shopify.
Count net installs from paid shops, not total installs, and ask your first merchants for reviews once they have used the app for a few weeks. You'll know you are close when the number in your Partner Dashboard, minus uninstalls, is heading toward 50 and the reviews describe outcomes rather than setup.
The mistake is reading the badge as a moat. It's position the host grants and can withdraw, which is the argument in our breakdown of why only one kind of distribution is a moat.
3. Zapier Promotion Starts at 50 Active Users a Quarter
Zapier lets you publish a public integration without proving demand first. The gate sits one step later, in its partner program, where the marketing and support benefits live.
Zapier's partner program documentation sorts public integrations into four tiers by active users and a health score. The minimums above Bronze are 50 active users for Silver, 350 for Gold, and 3,000 for Platinum, or 350 with 20 percent growth over the previous quarter.
Tiers are re-evaluated at the start of each quarter, and an integration that misses a tier's requirements moves down to the one it qualifies for. The health score looks at open bug reports, open feature requests and how quickly your team responds to them.
That makes the Zapier integration a retention job as much as a launch. Put it in your onboarding and your help docs so existing customers wire it up, and answer every bug report while the numbers are still small.
You've cleared it when 50 people use the integration within one quarter. The mistake is launching it with an announcement post and then never mentioning it again.
4. Google Workspace Marketplace Features Apps With 100,000 Installs
The Google Workspace Marketplace sets the highest published bar of the five, and it applies to featuring rather than listing. Google's page on getting your app featured says Editor's choice apps need at least 100,000 installations.
Newer apps get a lower bar, not a free pass. An app published within the last six months needs at least 10,000 installs and a rating of 4 or higher, and it also has to be a Workspace add-on that individuals can install on a free, freemium or trial basis.
The other featured category, Recommended for Google Workspace, runs as an annual application and requires an independent security assessment. Google is plain that you can't pay to get an app featured in a Marketplace category.
For a founder with 40 customers, the practical read is simple. The Google Workspace Marketplace listing is a place to send people who already know you, and featuring is a distant milestone rather than a launch tactic.
5. Atlassian Marketplace Ranks Apps on Installs, Reviews and Ratings
The Atlassian Marketplace publishes its ranking inputs, which makes it the clearest example of social proof deciding search position. Its documentation on Marketplace search results and rankings names three factors: keyword relevance, semantic match and an engagement score.
The engagement score reads the number of ratings and reviews, the average rating, the number of installs, and whether support details are provided. Two of the three factors reward a well-written listing, and the third rewards customers you already have.
Write the app name, tagline and brief description in the words your buyer uses for the problem, and fill in the support details, since that part is free. Then ask every early customer for a rating, because a new app with no reviews is ranking on text alone.
You'll see it working when your app appears for the problem phrase rather than only your brand name. The mistake is keyword stuffing, which Atlassian says makes it harder for customers to find what they need.
App Marketplace Gates Compared Across Five Stores
Side by side, the five stores gate different things, but every gate reads usage you already have. None of them can be cleared with money alone.
| App Marketplace | What Is Gated | Published Threshold | Signal It Reads |
|---|---|---|---|
| Slack Marketplace | Listing | 10 active workspaces, 10 weekly active users | Real usage in 28 days |
| Shopify App Store | Built for Shopify status | 50 net installs from paid shops, five reviews | Installs, reviews, rating |
| Zapier | Partner benefits | 50 active users for Silver | Quarterly users, health score |
| Google Workspace Marketplace | Editor's choice | 100,000 installs | Installs, rating |
| Atlassian Marketplace | Search rank | No fixed number | Installs, reviews, rating, support |
Read the third column as a to-do list. If you can't reach the number with the customers you have today, the store isn't your first channel yet.
Why an App Marketplace Listing Cannot Create First Customers
An app marketplace listing cannot create your first customers because every store ranks and promotes apps on the evidence those customers leave behind. With no installs, no reviews and no usage, a new listing competes on text against apps with years of social proof.
Look at what the stores read. Atlassian Marketplace scores installs and reviews, Built for Shopify counts paid installs and reviews, and Zapier counts active users by the quarter.
That is the loop founders walk into. The store surfaces apps with proof, proof comes from customers, and the customers have to come from somewhere the store doesn't control.
It also explains why the listing still matters later. Once you have customers, each review and install feeds a ranking system that keeps working while you sleep, which is the part of "free distribution" that is true.
Review Queues Cost More Than App Marketplace Fees
The real cost of an app marketplace launch is time in the review queue, not the entry fee. The Slack Marketplace is the clearest published case.
Slack splits review into two stages. Feedback from the preliminary review generally takes up to 10 business days, and the functional review, where a reviewer installs and tests the app, generally takes up to 10 weeks.
Your place in the preliminary queue resets each time you resubmit. A listing page with a broken privacy link can cost you another round of waiting before a reviewer ever opens the app.
Money buys less than you'd expect. The Google Workspace Marketplace states that you can't pay to be featured, and the one cost it names for its Recommended category is the security assessment, which the developer pays for and repeats every year.
- Budget the review window into your launch plan, not the week you submit.
- Check every link, screenshot and support address before submitting, since each resubmission restarts the preliminary queue.
- Expect to pay for security work, not for placement.
Build Demand Outside the App Marketplace Before You List
Before the app marketplace can amplify anything, you need customers it can count, and they come from channels you run yourself. Sequence the work by the gate you can clear today, not by the logo you want on your homepage.
- At zero customers, publish where there is no gate. Answer the problem your app solves in the communities where your buyers ask it, write the setup guide as a page on your own site, and talk to users one at a time.
- At around ten customers, clear the listing gates. The Slack Marketplace becomes realistic once ten outside teams use the app weekly, and a Shopify listing starts collecting its first reviews.
- At around fifty, go after amplification. That's the Zapier Silver threshold and the Built for Shopify install floor, so ask for reviews and put the integration inside your onboarding.
- Past that, treat ratings, reviews and support responsiveness as distribution infrastructure you maintain every week, not a launch task you finish.
The first step is where most of the leverage sits. Community answers still move buyers, which is the argument in our look at how Reddit still sends customers, and content marketing for tech companies works best here when each page answers one problem your listing will later rank for.
The listing also has to be found outside the store, on Google and inside AI answers, where buyers compare options before they ever open a marketplace. Better Marketing treats that as an AI SEO service job: the problem page and the listing should both be the answer an assistant can lift.
If you're weighing a B2B demand generation agency for this stage, ask how it builds trust before it asks for meetings. First customers here come from people who already know your name.
When an App Marketplace Listing Should Come First
List early when the app marketplace is the only permitted route to your buyer, but don't count the listing as a channel. Slack's documentation says that in order to commercially distribute your app, you must submit it to the Marketplace.
The same applies when your product only exists inside one host, like an add-on that means nothing outside Google Workspace. The listing is the storefront, so build it properly, then do the demand work anyway.
What changes is the expectation. You're listing to be allowed to sell, and the installs still have to come from people who heard about you elsewhere, whether from your own writing, your founder network or a B2B demand generation agency running outreach for you.
Check the Gate Before You Plan an App Marketplace Launch
Open the developer documentation of the app marketplace you're targeting and find the number: workspaces, paid installs, active users or reviews. If you can't clear it with the customers you have, the store is not your first channel.
Build those customers with content marketing for tech companies, an AI SEO service that gets your problem pages cited, community answers and direct outreach, then list and let the store amplify the proof. When you're ready to turn that early trust into first customers, Better Marketing works as a B2B demand generation agency built for exactly that stage.
The store is not free distribution. It's an entrance exam, and the answers are your customers.
