No-Show-Proof Scheduling for Coaches
Booking pages for solo coaches and consultants that block spam and take refundable deposits, with one-click refunds.
Founder thesis
Solo coaches and consultants with public booking links eat no-shows and junk bookings, and the incumbents either meter the fix or leave it manual. I am betting one flat per-host price that bundles screening and refundable deposits beats Calendly's free cap and Cal.com's substring filter. The pain is documented, the money is not.
What others got wrong
Calendly's free tier allows one event type and one calendar connection, which forces a solo with several offers onto Standard at $10/seat/mo.
Cal.com screens attendee emails with a substring match, so a booker slips through by adding characters to an allowed address and the host is left to screen by hand.
Deposits bolted onto Calendly through Stripe leave the host to refund by hand, logging in, finding the client, reversing the charge.
A plain scheduling link can end the conversation in sales-led outreach. One commenter wrote, 'Calendly link is a major turn off.'
What should work
Sell one flat per-host price that bundles three things rivals meter or leave manual: unlimited event types, true attendee whitelisting, and one-click deposit refunds.
Launch on Show HN the way this category rewards. Cal.com's 'open source Calendly alternative' post took 311 points and 91 comments.
Ship a 1-click Calendly importer so switching costs nothing, the same move Cal.com uses at signup.
Go after the sales-led host who is put off by sending a bare link, and screen the meeting before it is booked.
What kills it
- SavvyCal already sells to solos at $10/user/mo, so price is not the wedge.
- Cal.com gives away unlimited event types, calendars and meetings for free.
- The 60% no-show cut is the vendor's own claim, and skeptics in the same thread argue deposits also deter real bookings.
- No vendor in this category publishes revenue, ARR or customer counts.
What users want
4Stop spam bookings from getting through the email filter
A host who allow-listed one address saw a booker get in with a near-identical one, and wrote on Cal.com's issue tracker, 'This exposes us to possible spam bookings.'
Refund a deposit without hand work
SureMeet's founder said, 'With Calendly, you have to do the manual work of logging into your Stripe, finding the client and so on.'
Filter non-serious bookings off a packed calendar
One Hacker News commenter wrote, 'They likely have a packed calendar, and this would help them filter out non-serious buyers.'
Not send a scheduling link that kills the deal
A commenter on a sales-founder story wrote, 'No, I feel the same. Calendly link is a major turn off.'

| Cal.com launched as Calendso with a Show HN post titled 'An open source Calendly alternative' that drew 311 points and 91 comments. | hn.algolia.com✓ |
| SureMeet launched its Calendly no-show add-on with a Show HN post at 24 points and a same-week Product Hunt launch the founder announced in the thread. | hn.algolia.com✓ |

Your angle & pricing wedge
| Piece | Claim | Src |
|---|---|---|
| Angle | Solo-host scheduling with real spam screening, a true attendee whitelist, disposable-domain blocking and quiet decoy handling, plus refundable deposits with one-click refunds, so a public link stops costing the host no-shows and junk bookings. | |
| Wedge | One flat per-host price, around $12 to $15/mo, bundles three things rivals meter or leave manual: unlimited event types against Calendly's 1-event-type free cap, deposits with one-click refunds against the manual Stripe refund, and a true whitelist against Cal.com's bypassable substring filter. SavvyCal already serves solos at $10/user/mo, so the bundle has to be the wedge, and the price and willingness to switch are unvalidated. |
How others got traction
3| Move | Why | Src |
|---|---|---|
| A free tier with unlimited event types, calendars and meetings, plus a 1-click Calendly importer | The importer removes switching cost and the unlimited free plan undercuts Calendly's one-event-type cap. | cal.com✓ |
| Refundable deposits collected before booking, layered on existing Calendly links by SureMeet | The founder says it cut no-shows 60%, though skeptics in the same thread argue deposits also scare off real bookings, so the number is unverified. | hn.algolia.com✓ |
| An open source launch pitched as 'an open source Calendly alternative' on Show HN | It drew 311 points and 91 comments, though no founder statement ties the launch itself to Cal.com's later traction. | hn.algolia.com✓ |
Market heat
Cal.com's GitHub repo shows 48.5k stars and 15.2k forks.
Cal.com's launch post, 'Calendso: An open source Calendly alternative', drew 311 points and 91 comments on Hacker News.
Smaller wedge bets draw less. SureMeet's no-show add-on took 24 points on Hacker News plus a Product Hunt launch, and Tymeslot appeared on Show HN in March 2026.

Should you build this?
The pain is real and on the record: bypassable spam filters, hand-run deposit refunds, and prospects turned off by scheduling links. The money is unproven, no vendor here discloses revenue, and the space is crowded, with Cal.com giving away unlimited event types and SavvyCal owning the $10 solo tier. Build only after a test. Recruit 20 solo coaches or consultants with public booking links, have each show one spam or non-serious booking and one no-show with its cost from the last 30 days, then offer a $15/mo pre-order for whitelist screening plus one-click-refund deposits. Kill it if fewer than 6 produce both or fewer than 5 pre-pay.
