Claude: Saved “Barber booking” as a spark, with a pitch, the problem and who it is for. Demand looks real, but competition scores 3 out of 10: crowded. Want me to research the market?

One idea, looked at closely

Below is a real Vibestash deep research report on this idea, shortened. It ran three web searches, loaded every page it cites, and dropped claims whose page didn’t load. The score beside it is an example.

How the 54 is made

Out of 10 each; higher is better for the idea. Example score.

Demandsome demand6
Barbers already pay €15–50 a month for booking tools, and most surveyed salons still kept a paper diary before switching. No logged evidence yet.
Competitioncrowded3
Crowded: six rivals at €15–50 a month, and TerminTiger and Glambook give a single chair away free.
Effortquick to build7
Booking page, reminders and deposits: an AI builder can ship a first version in a few weeks.
Personal fitpartial fit6
Scored against the builder profile: some sales experience, 10 hours a week.

Demand is real but the field is crowded. Proceed only if barbers will pay for SMS or WhatsApp reminders and deposits that the free plans leave out.

Riskiest assumptions

Solo barbers will pay monthly when two rivals offer a free single-chair plan.highTest: Ask 20 solo barbers to pick €15, €19 or €25 for SMS reminders and deposits; count paid trials.
SMS reminders and deposits cut no-shows enough for barbers to notice.highTest: Pilot with 5 shops for 4 weeks and compare no-show rates before and after.
A barber can be live in ten minutes, walk-ins included.mediumTest: Time five setups in person with a stopwatch; note where they get stuck.

Stop rule: Stop if fewer than 5 of 20 barbers agree to a paid trial at €15 or more.

Market research: Barber booking

Buyers are independent barbers and small shops in Germany, roughly 12,000–15,000 by vendor estimates (no official count). Most still book by phone, paper or Instagram DMs. Paid plans run €15–50 a month and free tiers cover one chair. The best route is direct outreach: visit shops in one city, set up a booking link on the spot, and sell SMS reminders plus deposit-based no-show protection.

Demand

In a survey of 173 salons, 59% kept a paper appointment book before adopting software; about three-quarters of those without online booking are open to it. · calendall.com
76% of salons using reminders report fewer no-shows; daily booking calls fell from 7.0 to 3.2. · calendall.com
BarberBook charges €24.99 a month for one barber and claims 500+ shops (self-reported). · barber-book.de

Path to market

Several rivals send email-only reminders, or keep SMS and WhatsApp for higher tiers. A tool that gets a solo barber live in ten minutes, with SMS reminders and deposits at a flat price, answers the problem better than the free plans.

Visit shops in one district, set up the booking link on the spot (€0–50, 10–15 h a week)
Instagram DMs to barbers (€0, about 5 h a week)
Free beta with “Powered by” in client reminders (€0, about 10 h to build)
German-language guides on cutting no-shows (€0–50 a month, 3–5 h a week)

First move: Visit or DM 20 barbers in one district this week. Set up their booking link free for a month, and ask each one what they would pay afterwards.
First month: About €100–200 in the first month, and 40–60 hours of your time.

Decide

Know how long it takes, then hand it on

Vibestash works out your own tasks to a first launch from your profile, then writes a build brief your coding agent can start from. Progress comes back as the tasks get done.

About 4 weeks to live at 10 h a week (example)

Buy the domain and set up sign-in and the database
Connect SMS reminders and deposits
Write the privacy and terms pages
Visit 20 shops in one district

You can build this by chatting.

And the rest

Everything an idea needs before it is built

Sparks
Every new idea in one table: area, effort to explore, market fit and how it makes money. Sort by fit or by the quickest look.
A board from Exploring to Shipped
Drag ideas through the stages. Ideas you let rest keep their reason and their history, and can come back.
Evidence, not opinions
Log interviews, sign-ups, pilots and payments. Logged evidence sets the demand score; until then it says it is an estimate.
Stop rules
Write down when to drop an idea before you start. A failed high-risk test raises the rule so you notice.
Weeks to live
Your own tasks to a first launch, from sign-in setup to legal pages to outreach, divided by the hours you have each week.
30 tools in your AI
Claude, ChatGPT, Claude Code, Codex and Cursor can capture, score, research and hand off through one connector.

Your data

Kept in the EU, yours to take away

The vault lives in Frankfurt and the app runs in Belgium. A new idea goes to an AI provider once, to be filled in; after that only when you ask to rescore, brief or research it, under terms that forbid training on it. No ads, trackers or analytics. Export everything at any time, or delete the vault in one step. Read the privacy notice.

Your next build, chosen with evidence.
