Paid 'Pick Your Brain' Scheduler for Experts is a startup idea for consultants, experts, and creators. A successful solo consultant gets more and more 'grab a coffee and chat' requests that are really free consulting, and wants a polite but systematic way to charge or decline. A thread in r/Entrepreneur drew 142 upvotes and 221 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Calendly + Stripe, Intro.co, and Clarity.fm, and that still leaves this job open. Hotness is 3.65, Hot. Real but moderate pain. Clear willingness to pay. The thread drew 142 upvotes and 221 comments. Crowded with decent tools. Buildable in days. A first version is weekend-easy, about 1 week, priced as a fee on each transaction and charged as a fee on each transaction. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

A way through
A lightweight calendar add-on for 'pick your brain' requests that offers a paid 15-minute slot instead of a free meeting, with polite decline/convert templates.
MVP scope
- Give consultants, experts, and creators a way to do this in one sitting: Turn free coffee-chat requests into paid 15-minute slots, with polite decline templates.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a fee on each transaction, as a fee on each transaction. The free path must finish the core job once.
- Ship the web app only. Leave Calendly + Stripe to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Calendly + Stripe, Intro.co, Clarity.fm. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 1 weeks (1 week), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is consultants, experts, and creators. Charge a fee on each transaction, and test a price as a fee on each transaction. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
