Build once. Earn recurring revenue from the asset.
Micro SaaS & Digital Products
Engineers have a superpower in this module: you can actually build the thing. Most people who spot a problem can't build the solution. Most people who can build don't know what to build. Senior tech professionals are uniquely positioned to do both — because you work inside the systems that have the problems, and you have the skills to ship the fix. This module is about turning that advantage into recurring revenue.
This module fits you if
- Engineers who spot workflow problems others have learned to live with
- Those comfortable shipping imperfect things in public and iterating from feedback
- People who want income that doesn't scale with the hours they work
- Engineers with experience in a niche domain (devtools, fintech, health, legal tech)
- Those willing to treat the product as a business — marketing, support, and all
It's not the right fit if
- Those who want to build something for months before talking to any customers
- Engineers who won't sell — a great product with no marketing earns nothing
- Those who need immediate income — micro SaaS has a meaningful early ramp time
The playbook
Zero to one — step by step.
This is not a vague framework. It's the order of operations that actually works.
Find the problem — in a domain where you already have unfair advantage
The best micro SaaS ideas come from lived experience with a problem, not from market research. Think about: tools you've wished existed, workflows you've hacked together manually, integrations that don't exist between products you use every day, reports nobody pulls automatically, calculations people do in spreadsheets. The idea doesn't need to be novel — it needs to solve a real problem for a specific group of people who have money and will pay to stop doing it manually.
Validate before you build — one conversation is worth 100 hours of code
The most expensive mistake in micro SaaS is building for 3 months and then discovering nobody will pay for it. Before writing a line of code, talk to 10 people who have the problem. Not 'would you use this?' (everyone says yes) — 'how do you currently solve this, what does it cost you in time or money, and would you pay $X/month for a better solution?' If you can't find 10 people who have the problem, you haven't found the problem yet.
Build the smallest thing that proves the value — not the full product
Your v1 doesn't need a dashboard, a billing page, a public API, or a beautiful UI. It needs to solve one problem so clearly that someone would pay for it today. For a B2B tool, 'smallest thing' often means a Zapier integration or a spreadsheet automation before a full app. For a Chrome extension, ship the one feature. For a template, ship the template. Time to validation matters more than completeness.
Charge from day one — even to beta users
Free users don't give you useful feedback — they tell you what they want in a product they don't pay for. Paid users tell you what they need from a product they depend on. Even if it's $9/month or $29/month, charging from the start reveals your real conversion rate, creates real engagement, and gives you money to reinvest. 'Beta access' is fine — discounted pricing while features are still being built is a legitimate product positioning choice.
Launch publicly and distribute deliberately — a great product nobody knows about earns nothing
Launch on Product Hunt. Post in relevant Slack communities and subreddits where your target user hangs out. Write a 'how I built this' post on LinkedIn or your newsletter. Partner with people who already have the audience you need. Micro SaaS growth is often distribution-led, not product-led — the best distribution comes from the communities and content channels you've built. This is why modules compound: your consulting network, your content audience, and your newsletter subscribers all become launch distribution.

Who does this look like
Aisha Osei
Data Engineer → Digital Product Creator
Aisha spent 6 years building data pipelines and grew tired of manually building data quality reports every week. She spent 3 weekends building a simple tool that automated the reports she'd been generating manually. She put it on Gumroad for $49, posted it in two data engineering Slack groups, and made $2,100 in the first month. She rebuilt it as a proper SaaS at $29/month, launched on Product Hunt, and hit $6,800 MRR by month six. She now spends 6 hours/month on maintenance.
