I've poked around a while ago at some Calendly alternatives (specifically was lo... | Hacker News
I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 7 months ago

  • Ask HN: Publicly Sharing Revenue?
    This is called open startup.. you can see a list at https://openstartup.tm. - Source: Hacker News / 10 months ago
  • Ask HN: How much info should founders share with early stage employees?
    I don't know about _fully open_, but I think Buffer is an example of a company that shares unusually much. https://buffer.com/resources/revenue-dashboard/ There's some sort of list at https://openstartup.tm/ but I think a lot of companies listed there are open with only select pieces of info. Both of these are about public sharing though. Employee sharing is trickier to know from the outside. Perhaps Valve... - Source: Hacker News / almost 2 years ago
  • Sourcehut's 2021 Financial Report
    - https://openstartup.tm/ pros: if you're an early adopter, it's nice to know how the service you're investing time in is doing financially. One of the biggest risks of choosing a new/unknown service, as a consumer, is that it will fail/close and you'll have to migrate somewhere else. I think the open company movement has other benefits as well. Behind just financials, but companies sharing their employee... - Source: Hacker News / about 2 years ago
