Altium has only recenty started adding the features it needs to compete with Allegro and Xpedition. It's historically been oriented towards small-team efforts in the same niche as OrCAD and PADS.

The argument I see for Flux is the "FAE in a box" sorts of features for educating hobbyists and early-career design engineers while keeping them out of trouble. The person I imagine would otherwise not done a PCB at all. Someone who instead would have wired up up a bunch of prefab Arduino-type dev boards or bought small power supplies, DIN mount relays, and so on. Those features put a lot of things within the reach of technicians, panel designers, and systems integrators.

It's funny, Altium was the underdog for years. Only as they continually improved did they slowly gain market share.

The tools need to work consistently, just like the tools of a carpenter. If his hammer head keeps falling off, it's not very helpful even if it was free.

My point was that it is really difficult to make sch and pcb design easy for the end user. There are already companies that have climbed that mountain. AI is a nice differentiator, but in my opinion a startup would be better focused by working with existing tools instead of reinventing them (poorly).

Obviously startups are free to do as they wish.
