A solo founder does not need more software. They need a stack where every tool removes a category of work permanently.
The core nine
Framer for the site, Dub for attribution, beehiiv for the audience, Cal.com for scheduling, Stripe for revenue, Superhuman for inbox, Granola for calls, Make for the glue, and Wispr Flow for every word you write.
What it costs, what it returns
The full stack lands under a few hundred dollars a month and reliably returns ten to fifteen hours a week. At any reasonable value on founder time, this is the highest-ROI spend in the business.
