The product combines availability for multiple people into one group booking link, sends reminders, supports rescheduling, and detects participants’ time zones. The page describes users as solo professionals and teams in sales, recruiting, healthcare, development, and professional services.

Where customers come from

The site lists customizable booking links that can be shared online and embedded on websites. It also lists calendar integrations with Google Calendar, Office 365, and Outlook, API access for adding scheduling to products, and integration with more than 2,000 applications through Zapier.

What stands out

KalendMe combines multiple calendars, group booking links, automatic reminders, rescheduling, time-zone detection, API access, and Zapier integrations in one scheduling product. The page reports user satisfaction of 4.9/5 and cites a custom Rappi link delivered in less than 2 weeks that allowed the company to schedule hundreds of meetings.

Where it sits in the data

KalendMe's $2.2K a month is higher than 51% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that this is a real-work build. The buyer is a solo professional or team that coordinates meetings across calendars, and the product needs to handle calendar connections, availability, reminders, rescheduling, time zones, and booking links. The demand is tied to coordinating meetings across people and calendars.

My view is that distribution would come from booking links shared online, website embeds, calendar integrations, API partnerships, and Zapier connections. The difficult parts are maintaining reliable calendar connections, handling different customer workflows, supporting integrations, managing changes in connected services, and competing with established scheduling products.

Verdict: Needs real work.

One thing to take from it

The pricing structure pairs a free basic plan with a paid premium plan for teams that need branding, group links, team management, API access, Zapier integrations, and unlimited event types.
