going closed source does not mean we are not fighting fire with fire

we are using a handful of internal AI vulnerability scanners for months now

being open source simply reduces risk by 5x to 10x according to several security researchers we are working with https://cal.com/blog/continuous-ai-pentesting-vulnerability-...

Re:Going open-source as a VC-Backed company on Tuesday September 10, 2024 @07:02PM (#41506520)
whats so confusing about open core?

its open source for the masses and commercial for the very few enterprise with paid addons

https://en.wikipedia.org/wiki/Open-core_model

definitely the best of both—sustainability and freemium OSS for hobbyists and small companies

this is dope. congrats!

hello
hey cofounder of cal.com here. the plan has always been to: 1. start and go fast with a mono repo and trpc fullstack api to understand and learn the fastest. once we knew what we need, we were able to build an external facing API. we wanted to be very clear to externals that using our “trpc api” is with caution due to undocumented breaking changes. a lot of companies have an internal API + external API (built later)

Re:Show HN: OpenSign – The open source alternative to DocuSign on Wednesday November 01, 2023 @09:30AM (#38097917)
how is this different to Documenso.com? that looks more advanced
what inspired you to start this? always curious
hey, peer here, cofounder of cal.com. We are quite fortunate to have a growing enterprise business that is subsidising the free plan.

we will never raise prices for the free plan, free stays free, especially since it's open source which means if we were to raise, it would compete with the self-hosted product and we really dont want that

rest assured, we are comfortable providing a free product with enterprise customers

thank you for supporting us! The CalDAV integration alone took a ton of engineering hours because every provider has implemented this protocol differently
thank you @brajeshwar, we're happy to keep our individuals plan free forever thanks to the growing enterprise business
aww thank you man! really means a lot to hear @zcesur
hey @ushakov, can you send me an email to [email protected], can i look into your 2FA issue?
