Kasspian’s honest read
One of the best bootstrapped models if you pick a painful niche you can actually reach — distribution, not code, is what kills most micro-SaaS.
Who actually pays
A specific professional niche that already pays for tools and feels a recurring pain in their workflow — agencies, e-commerce sellers, freelancers, or a vertical SaaS's underserved power users who'll pay $20-100 a month to remove friction.
Riskiest assumption
That you can reach the niche cheaply and repeatably. The product is usually buildable by one person; the failure mode is having no distribution channel and nobody hearing it exists.
Cheapest test first
Find where the niche already gathers — a subreddit, Slack, forum — and offer to solve the pain manually or with a landing page and a waitlist. Real signups or pre-orders from strangers, not friends, is the signal.
Micro-SaaS is the closest thing to a sane bootstrapped business: small enough for one person to build and maintain, sticky enough to compound, and aimed at a niche too small for the big players to bother with. The math works because subscription revenue stacks and good niche tools rarely churn. This is a genuinely good model, and the reason it's good is also the reason it's crowded — so picking the right narrow pain matters more than the build.
The trap is building in a vacuum. Most micro-SaaS deaths aren't technical; they're founders who shipped a clean product into silence because they had no way to reach buyers and no audience to start from. Before you write code, prove you can get the attention of the exact people who'd pay — own a channel, a niche community, a content angle. If distribution is solved, micro-SaaS is one of the better odds a solo founder can take.
