Calenteri
Peer-to-peer scheduling is a tough lane to own. Calendly basically owns the default mental model for "send me a link and I'll grab a time," and Google Calendar is right there for most people who just want to share availability. So when I see a new entrant like Calenteri, my first instinct is to ask what specific pain point it's actually solving that the incumbents haven't addressed.
Maybe the angle is more consumer-facing, or maybe it's built for a particular vertical where the two-sided nature of booking matters more, like tutoring, consulting, or even social scheduling. I'd want to know whether the product handles the awkward back-and-forth of negotiating times between two equally busy parties, because that's genuinely clunky in existing tools. Most scheduling software assumes one person has authority over their calendar and the other just picks a slot. True peer-to-peer is a different dynamic.
The description is so thin that I can't tell if this is a serious venture or a side project. Either way, the bar for adoption in this space is brutal. People won't switch scheduling tools unless there's a clear, immediate win, and even then, network effects matter. I'll be curious to see if Calenteri finds a wedge or fades into the long tail of calendar apps.
