I wasn't defining as feature parity and didn't think you implied that anywhere.

If you've come up with a way to perform as well as Slack at the basic multi-client message service at launch, that's great. "that doesn't suck"/"that just works" reads to me like more the claims of a low cost MVP that hasn't solved those issues yet. (Probably because they're overused.)

Only speaking to your marketing and not intending to impugn your team credentials/experience.
