Securing your first 100 users is a massive milestoneâit validates your product, uncovers real customer insights, and gives early traction that investors love to see. But getting there takes more than a good idea. It takes strategy, persistence, and a solid understanding of who your users really are.
In this post, we break down proven ways to attract, engage, and retain your first 100 users as a UK startup founder.
đ§ Step 1: Know Your Ideal User Inside Out
Before you build, market, or sellâknow who youâre targeting.
â
Create a detailed user persona: industry, job role, pain points, goals, and buying behaviour.
â
Focus on a narrow, well-defined nicheâespecially early on. Solving a specific problem for a specific user wins over trying to please everyone.
đĄ Example: Instead of targeting âsmall businessesâ, target âUK-based independent online retailers struggling with inventory managementâ.
đ˘ Step 2: Build Buzz Before You Launch
Start marketing before your product is even ready. This helps you build an early community and gather feedback.
Ways to build pre-launch momentum:
- đ¨Â Create a waitlist landing page with an incentive to sign up.
- đŁÂ Share behind-the-scenes content and product updates on LinkedIn and Twitter/X.
- đ¤Â Join relevant communities (Slack groups, Subreddits, Facebook groups, or industry forums).
- đŹÂ Talk to potential users 1-on-1 to test messaging and identify early evangelists.
đ Step 3: Use Personal Outreach to Drive Your First Signups
In the early days, scalable tactics wonât workâyouâll need to hustle.
Try this:
- Write a list of 100 potential users (people in your network, LinkedIn connections, event attendees).
- Reach out with a short, tailored message and a clear ask.
- Offer a demo, free trial, or early access in exchange for feedback.
People are far more likely to try something when you ask directlyâespecially if they feel theyâre part of the journey.
đź Step 4: Leverage Your Network and Existing Communities
Your first 100 users will likely come from:
- Your professional network (past colleagues, mentors, local accelerators).
- Online communities where your users already spend time.
- Industry events or meetups (in-person or virtual).
Donât just postâengage meaningfully. Comment, help others, and build relationships.
đ Word of mouth is powerful in these early stagesâso delight every early user and encourage them to refer others.
đ Step 5: Track, Learn, and Optimise
What gets measured gets improved. Start tracking early:
- Signups by source (to know where users are coming from)
- Activation metrics (what actions define a âsuccessfulâ user)
- Retention and churn (do they stick around after signing up?)
Use tools like Mixpanel, Amplitude, or even just Google Sheets to begin.
Refine your messaging, onboarding, and user experience based on what the data tells you.
đ Bonus Tip: Create a Feedback Loop
Use tools like Typeform, Intercom, or simple emails to regularly ask:
- Why did you sign up?
- What do you like or dislike so far?
- What feature would make this 10x better?
This real-time input helps you make fast improvements and makes users feel valuedâwhich increases loyalty.
đ§ Final Thoughts
Nailing your first 100 users is part strategy, part hustle, and all about building relationships. Donât chase perfectionâget your product in front of people, listen, adapt, and iterate.
Remember: your first 100 users will shape your roadmap, validate your assumptions, and give you the traction needed to attract investors.
