How to get your first 100 SaaS users

Direct answer

Reach the first 100 SaaS users by doing unscalable work deliberately: interview a narrow group, onboard people personally, record why they activate or leave, and double down on the first channel that produces retained usage. One hundred registrations are less useful than a smaller group repeatedly completing the core job.

Define a qualified user

Write the behavior that makes someone count: role, problem, access to required data, and willingness to try the workflow now. Define activation as a completed outcome, not account creation. This prevents broad promotion from hiding weak product fit.

Find the first twenty

Start with interview participants, professional contacts, previous colleagues, integration users, and small communities where the problem is discussed. Send individual messages that reference a real reason for contacting each person. Offer founder-led onboarding and ask permission to observe the first session.

Track every conversation in a simple table: source, user type, problem, first action, blocker, next step, and follow-up date. A CRM is optional; disciplined notes are not.

Turn learning into acquisition

After twenty activated users, group them by shared trigger and source. Write a case study or guide that explains the workflow in their language. Ask satisfied users for an introduction to one peer. Build templates, integrations, and landing-page sections around repeated use cases rather than hypothetical personas.

Use launch communities for concentrated discovery, but retain ownership of the relationship through good onboarding, useful email, and reliable support. Never buy accounts, reviews, or votes.

Progress from 20 to 100

1. Keep one manual outbound or community channel running every week.
2. Publish one high-intent resource based on repeated customer questions.
3. Improve the activation step with the largest observed drop-off.
4. Ask why active users would be disappointed if the product disappeared.
5. Review retention by cohort before increasing traffic.

When one channel produces qualified users consistently, document the message, targeting, workload, conversion, and retention. That is the beginning of a repeatable system.

Frequently asked questions

Should the first 100 users be free?

Not automatically. Charge when payment is part of validating the problem and value. A limited founder plan or trial can reduce friction, but record whether users would pay afterward.

Which metric matters most for the first 100 users?

Use the rate at which qualified users complete and repeat the product’s core job. Pair it with interview evidence so you understand why the behavior occurs.
