Perhaps. Hard to say. The dev team was large by necessity, but the GTM was far too large because we hadn't come to terms with giving up on enterprise and individual sales. Had we focused exclusively on public sector and hunkered down we MAY have been able to be profitable on an operational basis. But we would have had to recap and get existing investors to write it off at a time when the board had two offers on the table that returned some value to investors. Not straightforward.
Today it could almost certainly be built MUCH more economically - likely on the not-dissimilar and rich/mature matrix.org infra at the bottom, and using Electron on top.
And I would sell not to enterprises nor to decentralization zealots: I'd build a small focused GTM org focused on public sector and those who will need to collaborate when trying to deal with an APT.
