How Vibe Coders Can Find Their First 10 Paying Customers

A weekend with an AI coding tool can now produce an app that would have taken a small team a month a few years ago. Getting your first paying customers hasn't sped up at all, so distribution is now the slow part of launching a small product. Most vibe coders find that out the week after they ship.

The usual advice is to post on social media and wait. That works for a few people with an audience. Everyone else needs a list of businesses that have the problem the app solves, a reason those businesses would talk to an unknown developer, and a plan for the next fortnight.

This guide uses one source for all three: UK companies that registered at Companies House in the last 30 days. They are new, they need tools and nobody has sold them anything yet.

Why companies under 30 days old make good beta users

A company that has traded for five years judges your app against the tool it already pays for. It will ask about integrations, data migration and your support hours, and it is right to. A company incorporated three weeks ago has nothing to migrate. Its founder is setting up a bank account, a website and a way to get paid, often all in the same week.

That makes new companies forgiving early customers. They have no habits to break, and they are used to trying things because everything they use is new to them. If your app is rough at the edges, a founder who started last month is more likely to tell you what's wrong than to quietly cancel.

There are a lot of them. In Company Explore's registration data, 62,561 UK companies were incorporated in the 30 days to 18 October 2026, about 2,800 on an average weekday and around 600 on a weekend day. Even a narrow niche refills itself every week.

Hairdressing and beauty alone added 1,129 companies in 30 days, roughly 260 a week, and 270 in the seven days to 18 October. You need ten customers. If a few hundred new prospects appear in your niche every week, the problem is how you approach them. If you haven't picked a niche yet, our post on micro SaaS niche ideas shows how to choose one from these numbers.

Make an offer a new founder can say yes to

A three-week-old company won't sign an annual contract with someone it has never heard of. It might say yes to something smaller and more personal. Three parts work together:

• Founder pricing: a lower price, fixed for as long as they stay a customer, in return for using the app early. Make it a real paid plan, even if it is cheap. A customer who pays a little tells you far more than a free user.
• A setup call: offer to set the app up with them, on a call, using their own details. For a founder with fifty other jobs that week, having it done for them is often the selling point.
• Feedback calls: ask for a 20-minute call after two weeks of use. Say upfront that you will change the product based on what they tell you, then do it.

Keep the number of beta places small and say so. "I'm taking ten founding customers" is true and gives people a reason to reply this week instead of next month.

A two-week plan to win your first paying customers

The plan below assumes you have a working app and about two hours a day.

1. Day 1: pick one SIC code and one region if you sell anything local. Pull every company in that code incorporated in the last 30 days from the B2B List Builder.
2. Day 2: remove dissolved companies, obvious holding companies and anything that doesn't fit. Run an enriched export to add the company's published website, email and phone, plus suggested director profiles on LinkedIn, Facebook or Instagram. Check any profile match before you use it.
3. Day 3: read 20 company websites or social pages. Note what each founder seems to be struggling with and write your first message around the most common problem.
4. Days 4 and 5: send 20 to 30 personal messages a day. Keep each one short and specific to the company.
5. Days 6 and 7: reply to everyone who answered, book setup calls and run the first ones. Note every question they ask, because those questions are your missing onboarding.
6. Day 8: pull the companies that registered since Day 1 and add them to the list. Lead with whatever objection came up most in week one.
7. Days 9 and 10: send the second round of first messages, plus one follow-up to anyone from week one who opened but didn't reply.
8. Days 11 and 12: fix the two things your first users complained about most. Tell them you fixed it.
9. Days 13 and 14: run feedback calls with your earliest users and ask which of them will pay at the founder price. Ask them who else they know who has just started a business.

Weekend registrations are low, so Monday is a good day to refresh your list. If ten paying customers in two weeks turns out to be ambitious for your product, the same routine keeps working for a third and fourth week.

How to write outreach that new founders read

New company directors get plenty of unsolicited email in their first weeks, and much of it comes from formation upsells and card terminal sellers. Yours should read like it came from one person who looked at their business.

• Opening: mention that they registered recently and what they do. "Saw you set up [company name] last month" is enough.
• Problem: name one job your app does that a business at their stage has to sort out now, such as taking deposits for bookings or sending a first quote.
• Ask: offer a founding place or a setup call. Don't ask for a demo or a "quick chat" with no purpose.
• Length: under 100 words, from your own name, with a real signature and a way to opt out.

Be honest about being small. "I built this for salons and I'm looking for ten to help shape it" is a better pitch to a new founder than pretending to be a big company.

Check the rules before you send anything. Under PECR you can email limited companies at corporate addresses without prior consent, as long as you say who you are and offer an easy opt-out. Sole traders and some partnerships count as individuals and need consent first. Under UK GDPR, legitimate interest usually covers relevant B2B prospecting. Our GDPR guide goes into the detail.

Run feedback calls that change the product

A feedback call with a beta user is only worth the time if you come away knowing what to build next. Ask about their week before you ask about your app. What did they spend time on, what did they put off and what did they pay for? Then ask them to share their screen and use the app while you watch.

Write down where they hesitate and what they search for that isn't there. Don't defend the product on the call. If three of your first ten customers ask for the same thing, build it before you contact the next batch, then tell those three it's done.

Track what turns a reply into a payment

Keep a simple sheet with each company's SIC code, incorporation date, date of first contact, reply, call and payment. After two weeks you will see whether younger companies reply more than older ones, and which message worked. If one niche gives you three paying customers and another gives you none, move your effort to the first one.

Frequently asked questions

How do I get first customers for my app?

Pick one type of business that has the problem your app solves, find the companies of that type that registered in the last 30 days and send each founder a short, specific message. Offer founder pricing and a setup call in place of a free trial with no contact.

Should my first customers pay?

Yes, if you can manage it. A small payment shows the problem is real and the user is serious, and paying customers give more honest feedback than people using something for free.

How many companies should I contact to get ten customers?

It depends on your niche, your offer and your message, so track it from the first day. Start with a few hundred newly registered companies in one niche and adjust once you see your own reply and payment rates.

Where can I find newly registered UK companies?

Browse recently created companies for a quick look, or use a list builder to filter by SIC code, location and incorporation date and export the results with published contact details.

To build your first beta list, open the B2B List Builder, pick your niche's SIC code and set the incorporation date to the last 30 days.
