Why we picked it This is the most direct answer to your question we could find: a step by step method for someone with a job and a few spare hours to pick an audience they already belong to and size it so it is reachable. Kahl has you list audiences from your own hobbies, past jobs and communities, then rate them for affinity, real problems, budget and market size. He is explicit that the whole exercise fits into a week of evenings, which is the constraint you are working under.
Finding an Audience for Your Side Business
From The Bootstrapped Founder by Arvid Kahl about a 20 minute read
- Start from audiences you already belong to (hobbies, past jobs, communities), then rank them.
- Score each one on affinity, real problems, willingness to pay, and market size before committing.
- Aim for the Goldilocks zone: big enough to sustain you, small enough that giants ignore it.
