How I Quit My Job And Launched A SaaS Company From Spain - Starter

Real demand

After leaving Eventbrite, Mitch Colleran taught himself to code and built Join It, a SaaS that lets organizations sell and track memberships; by March 2019 it had roughly 700 paying organizations and $20K/month on a $29/month entry plan.

Real-demand verdict

Real demand

It replaces spreadsheets and manual admin work for organizations managing members and dues, which is recurring operational necessity rather than a nice-to-have. The founder says product-market fit is reached but pricing and business model are still being tuned.

How it makes money

Organizations pay a monthly subscription; the most popular plan is $29/month, renewed as long as they keep managing members through it.

What old behavior it replaces

Spreadsheets and manual admin processes organizations used to track members and collect dues

Where the first customers came from

First 10 paying customers came after three months of full-time building in Spain; early traffic came from Google AdWords while iterating on customer feedback

Tactics you can copy

01At a $29 price point, do phone and chat support that most SaaS companies skip at this customer value, trading service for retention
02End every customer conversation with 'if we built this, would you pay for a subscription?' and prioritize by willingness to pay, not feature lists
03Ship a minimal hosted version and start paid acquisition early, letting real customers define what is missing instead of waiting for a complete product

Moving it to an AI business

Low-priced AI tools face the same thin-margin support problem; the transferable moves are trading manual service for early retention, ranking features by stated willingness to pay, and logging which channels (paid referrals, cold email, social ads) failed.

Evidence and limits

Self-reported numbers are unaudited — treat them as leads, not facts

What evidence is missing

The page header says $40K/month while the body says $20K/month as of March 2019; both are founder self-reported and unaudited
No CAC, churn, or retention figures, so unit economics at the $29 price point cannot be verified
No channel-level breakdown of the 700 paying organizations; channel performance is only described qualitatively
