- UK Reddit communities (r/SideHustleUK, r/UKPersonalFinance) are underused gold mines for early traction
- Cold email is legal in the UK under GDPR legitimate interest -- but always include an opt-out
- Do things that do not scale first: manual outreach, personal demos, white-glove onboarding
- Talk to customers before building features -- the feedback from 10 paying users beats 1,000 survey responses
How to find your first 10 SaaS customers in the UK
You have built the thing. Maybe you used Claude Code to scaffold it in a weekend. Maybe you spent three months refining it. Either way, you have a working product, a Stripe checkout page, and zero customers.
This is the moment most SaaS founders stall. Building is comfortable. Selling is not. But your first 10 customers are the most important milestone in the life of your business — not because of the revenue (at GBP29/month each, that is GBP290/month), but because of what you learn.
Your first 10 customers will tell you whether your pricing works, which features actually matter, what language resonates, and whether the problem you are solving is painful enough to pay for. Every conversation is research. Every sign-up is a data point.
Here are 10 practical, UK-specific strategies to find those first 10 paying customers.
1. UK Reddit communities
Effort level: Medium. Requires consistent presence over 2-4 weeks.
Reddit is the most underrated customer acquisition channel for UK SaaS founders. The platform has dedicated UK communities where your target customers are already discussing the problems you solve.
Where to look:
- r/SideHustleUK — people actively building income streams. If your tool helps freelancers, creators, or side project builders, they are here.
- r/UKPersonalFinance — financially motivated, data-driven. Good for fintech, budgeting, and money management tools.
- r/startups — global but active with UK founders. Great for developer tools and B2B products.
- Niche subreddits — r/UKLegalAdvice for legal tech, r/UKProperty for property tools, r/FreelanUK for freelancer products. Find the subreddit where your customers congregate.
What to say: Do not post "I built a SaaS, please buy it." That gets you banned. Instead, contribute genuinely to discussions. Answer questions. Share relevant insights. When your product is genuinely relevant to a thread, mention it naturally: "I actually built a tool that handles this — happy to share if anyone is interested."
What NOT to say: Anything that reads like an advertisement. Reddit users can smell marketing from a mile away and will downvote you into oblivion.
The play: Spend 15 minutes a day for two weeks engaging authentically in relevant subreddits. By week three, you will have built enough credibility to mention your product without being dismissed.
2. UK Facebook groups
Effort level: Low to medium. Less time than Reddit, but requires approval to join groups.
Facebook groups are where non-technical UK business owners congregate. If your SaaS targets small business owners, tradespeople, freelancers, or local businesses, this is where they are.
Where to look:
- Industry-specific groups: "UK Freelancers," "Small Business UK," "UK Startups and Entrepreneurs"
- Local business groups: "Manchester Business Network," "Bristol Entrepreneurs"
- Problem-specific groups: "UK Landlords Forum," "Accountancy for Small Business UK"
What to say: Ask questions first. "What is the most frustrating part of [problem your tool solves]?" Then listen. When you understand the language your potential customers use to describe their pain, use that language when you introduce your product.
What NOT to say: Do not drop links without context. Most groups have rules against self-promotion. Ask the admin before posting about your product, or frame it as asking for feedback: "I have built a tool that does X — would love feedback from people who deal with this."
3. Product Hunt
Effort level: High for one day, low ongoing. Requires preparation.
Product Hunt is global, but UK products do well. The audience is early adopters who actively seek new tools and are willing to pay for things that solve real problems.
The play: Prepare your launch properly. You need a clear description, a demo video or screenshots, and a launch-day strategy. Ship a "coming soon" page first to collect upvotes, then launch when ready.
Timing: Launch at 00:01 Pacific Time (08:01 UK time). You want the full 24-hour window. Have 10-15 supporters ready to upvote and comment genuinely in the first hour.
What to expect: A good launch brings 500-2,000 visitors in 24 hours. Conversion rates vary, but even 1-2% gives you 5-40 sign-ups. Not all will convert to paid, but some will — and the rest become leads.
4. Indie Hackers and Hacker News
Effort level: Medium. Requires storytelling and genuine engagement.
Both platforms value transparency and building in public. If you are willing to share your journey — revenue numbers, mistakes, lessons — these communities will support you.
Indie Hackers: Post about your product in the relevant group. Share your monthly revenue updates. The community is supportive of early-stage founders and will give you honest feedback. Many successful SaaS products found their first customers through Indie Hackers' milestone posts.
Hacker News (Show HN): Higher risk, higher reward. A "Show HN" post that reaches the front page can bring thousands of visitors. But Hacker News users are critical — if your product is half-baked, they will tell you. Launch here when your product is solid.
What to say: Lead with the problem, not the product. "I spent 3 months manually doing X, so I built a tool to automate it" resonates more than "Here is my SaaS, it has 47 features."
5. LinkedIn outreach
Effort level: Medium to high. Requires targeted research and personalisation.
LinkedIn is the most direct path to B2B customers in the UK. Decision-makers are there, they are reachable, and they expect business-related messages.
Connection requests vs InMail:
- Connection requests are free and more effective. Personalise every request with a note explaining why you want to connect. Keep it to one or two sentences. Do not pitch in the connection request.
- InMail costs money (requires Premium at GBP60/month or Sales Navigator at GBP70/month). Use it for high-value prospects you cannot reach via connection requests.
The sequence:
- Connect with a personalised note (no pitch).
- Once connected, send a brief message acknowledging their work or company.
- After 2-3 exchanges, mention your product in the context of a problem they have described.
What to say: "I noticed you run [type of business]. I have been building a tool that helps with [specific problem]. Would you be open to a quick look? No pressure — genuinely interested in your feedback."
What NOT to say: Do not send automated bulk messages. LinkedIn users in the UK receive dozens of generic pitches weekly. Yours needs to be obviously personal or it goes straight to "ignore."
Volume: Aim for 10-15 personalised connection requests per day. Expect a 20-30% acceptance rate and a 5-10% reply rate on follow-up messages. That means 100 connections could yield 5-10 conversations, and 1-3 customers.
6. Local meetups and co-working spaces
Effort level: Low. One event per week, 2-3 hours each.
In-person networking is underrated in the age of AI. UK cities have thriving startup and tech communities, and the people who attend meetups are exactly the kind of early adopters who try new tools.
Where to look:
- London: Silicon Roundabout meetups, London Tech Week events, Shoreditch co-working spaces
- Manchester: TechNorth events, Manchester Digital, Federation House
- Bristol: Engine Shed, TechSPARK, Watershed
- Edinburgh: CodeBase, Edinburgh Tech Meetup, Turing Fest community events
The play: Attend events relevant to your target market. Do not pitch from the stage. Have conversations. When someone describes a problem your tool solves, say: "I actually built something for that. Can I show you sometime?" Exchange details and follow up within 24 hours.
What NOT to say: Do not open with your elevator pitch. Ask what people are working on. Listen. The pitch happens naturally when the context is right.
7. PeoplePerHour and Bark.com
Effort level: Medium. Requires doing the work manually at first.
This is the "do things that do not scale" strategy. Before selling your SaaS tool, sell the outcome your tool delivers — as a service.
The play: List yourself on PeoplePerHour or Bark.com offering the service your SaaS automates. If your tool generates invoices, offer invoicing services. If it analyses data, offer data analysis.
Deliver the work using your own tool. The client gets the result they need. You get:
- Proof that people will pay for this outcome
- Real-world feedback on your tool
- A customer to convert to self-service when they see how it works
Example: "I will set up your automated invoicing system for GBP150." You use your SaaS to do it, then show the client: "This took me 20 minutes using my tool. You could do this yourself for GBP19/month."
This approach validates demand and acquires customers simultaneously.
8. Cold email (GDPR-compliant)
Effort level: High. Requires research, list building, and careful compliance.
Cold email gets a bad reputation because most people do it badly. Done well and legally, it is one of the most effective B2B customer acquisition channels in the UK.
GDPR compliance for B2B cold email:
- You can email business contacts under the legitimate interest legal basis if your product is genuinely relevant to their business role
- You must include a clear, easy opt-out mechanism in every email
- You must honour unsubscribe requests immediately
- You must identify yourself and your company clearly
- You should be able to explain why you believe the recipient would benefit (this is the legitimate interest test)
- B2C cold email has stricter rules under PECR — generally requires prior consent
The approach:
- Build a targeted list of 100-200 prospects. Use LinkedIn, company websites, and business directories.
- Write a short email (under 150 words). Lead with the problem, not your product.
- Personalise the first line for each recipient. Reference their company, role, or a specific challenge in their industry.
- Include one clear call to action: a question, not a demand. "Would a 15-minute demo be useful?" works better than "Sign up now."
- Follow up once after 3-5 days. If no reply after the follow-up, move on.
What to say: "Hi [Name], I work with [type of business] in the UK and noticed that [specific problem] is common in [their industry]. I have built a tool that [brief description]. Would it be helpful to see a quick demo? Either way, no worries — happy to share some free resources on [topic] if that is more useful."
What NOT to say: Anything that feels like a template. If the recipient cannot tell it was written specifically for them, it will be deleted.
Expected results: A well-targeted cold email campaign to 200 UK businesses should yield 10-20 replies and 3-5 demo calls. From 5 demos, expect 1-2 customers.
9. Content marketing and SEO
Effort level: High upfront, compounds over time.
Content marketing will not get you your first customer this week. It will get you a steady stream of customers six months from now.
The play: Write 2-4 blog posts per month targeting keywords your potential customers are searching for. Focus on problem-aware queries: "how to [solve the problem your tool addresses]."
Build your content with Claude Code to save time — it can research topics, suggest outlines, and even draft posts that you then edit for voice and accuracy.
Why it works: SEO traffic is free and compounds. A blog post ranking on page one for a relevant keyword can bring 100-500 visitors per month indefinitely. At a 2% conversion rate, that is 2-10 new customers per month from a single post.
The catch: It takes 3-6 months for content to rank. This is a long game. Start now so it pays off later, but do not rely on it for your first 10 customers.
10. Your existing network
Effort level: Low. One afternoon.
This is the easiest and most overlooked strategy. You already know people who might be your customers — or who know people who are.
The play: Make a list of everyone you know who might benefit from your tool or know someone who would:
- Former colleagues
- Friends who run businesses
- Ex-clients
- University connections
- Social media contacts
Send each person a personal message: "I have been building [product]. It helps [type of person] with [problem]. Do you know anyone who might find this useful? I am looking for early users and would love feedback."
Why it works: Warm introductions convert 10x better than cold outreach. People trust recommendations from people they know.
What NOT to say: Do not send a mass email. Each message should feel personal and specific to the recipient.
The mindset: first 10 are about learning
Revenue from your first 10 customers will not change your life. At GBP29/month each, that is GBP290/month — not enough to quit your job, but enough to validate that real people will pay real money for what you have built.
The real value is what you learn:
- Which features do they actually use? You built 20 features. They use 3. Focus on those 3.
- What language do they use? The words customers use to describe their problem should be the words on your landing page.
- How did they find you? The channel that delivered your first customers is likely the channel that will deliver your first 100.
- What nearly stopped them from signing up? Fix those friction points before scaling.
Talk to every early customer. Not via support tickets — properly. Jump on a 15-minute call. Ask what is working and what is not. These conversations are worth more than any analytics dashboard.
A practical 30-day plan
Week 1: Foundation
- Message 20 people from your existing network (strategy 10)
- Join 5 relevant Reddit communities and start engaging (strategy 1)
- Join 3-5 UK Facebook groups (strategy 2)
Week 2: Outreach
- Send 10-15 LinkedIn connection requests per day (strategy 5)
- Attend one local meetup or co-working event (strategy 6)
- List your service on PeoplePerHour (strategy 7)
Week 3: Scale up
- Build a cold email list of 100 targeted prospects (strategy 8)
- Send first batch of 50 personalised emails
- Post your journey on Indie Hackers (strategy 4)
Week 4: Launch and iterate
- Prepare and execute a Product Hunt launch (strategy 3)
- Follow up on all conversations from weeks 1-3
- Publish your first SEO-targeted blog post (strategy 9)
By the end of 30 days, you should have had 30-50 genuine conversations with potential customers. If your product solves a real problem, 5-10 of those conversations will convert.
Five things to remember
-
First 10 are about learning, not revenue. Every customer teaches you something. Every conversation is research.
-
Do things that do not scale. Personal messages, manual demos, white-glove onboarding. These do not scale to 1,000 customers, but they are perfect for 10.
-
Lead with the problem, not the product. Nobody cares about your features. They care about their pain and whether you can fix it.
-
UK-specific channels work. Reddit UK subs, local meetups, LinkedIn with UK targeting, GDPR-compliant email — these are your home turf advantages.
-
Talk to customers before building more features. The feedback from 10 paying users is worth more than 1,000 survey responses.

Frequently Asked Questions
Is cold email legal in the UK?
Yes, for B2B outreach. Under GDPR, you can email business contacts under the 'legitimate interest' legal basis if your product is genuinely relevant to their business. You must always include an easy opt-out and honour unsubscribe requests immediately. B2C cold email is more restricted under PECR and generally requires consent.
How long does it take to find 10 customers?
Typically 4-12 weeks of consistent effort. Some founders land their first customer in week one through personal networks. Others take longer because they are refining their pitch. The speed depends on how well-defined your target customer is and how directly you can reach them.
Should I offer discounts to early customers?
Yes, but frame it as founding member pricing, not a discount. Offer a lower price locked in for life in exchange for feedback and testimonials. This gives early customers a reason to commit and gives you social proof for later marketing.
What if nobody wants to pay?
That is valuable information. If 50 conversations produce zero paying customers, the problem is either your product, your positioning, or your target market. Go back to the feedback. What did people say they needed instead? Pivot toward the pain they described, not the solution you imagined.
Do I need a marketing budget?
Not for your first 10 customers. Every strategy in this guide is free or nearly free. Paid advertising makes sense later when you have product-market fit and want to scale. Spending money on ads before you have 10 happy customers is almost always a waste.
