What it is

You design, build and run your own web-based product that solves one narrow problem, such as invoicing for photographers or scheduling for tutors, and you handle support and updates.

Your first three steps

  1. Talk to 10 people in one niche to confirm a problem they would pay to solve
  2. Build a minimal first version and set up simple payments through a processor like Stripe
  3. Invite a handful of early users, charge from the start, and collect feedback
Who pays

Small businesses, freelancers or consumers in a specific niche who subscribe monthly or yearly.
