Why Scott left the Marines for startups

Scott Sanders has seen the defense tech industry from just about every angle. As a Marine officer, he watched promising capability stall somewhere between a program office and the field. As an early employee at Anduril, he helped build one of the companies that bet it could do better.  

Now, as Chief Growth Officer at Forterra, he's making that same bet on autonomous ground systems, a market that's been promised for years and is only now being put to the test. In this episode of Valley of Depth, we press Scott on what's actually working, what isn't, and where the hype is running ahead of the hardware.

We get into:

• Why the gap between a cool tech demo and a real defense business is wider than most founders think
• What investors still fundamentally misunderstand about defense timelines and business model risk
• Why most defense startups won't become primes and what the ones that do have in common
• How Forterra is approaching autonomy, mesh networking, and distributed operations at the tactical edge
• What it looks like to actually get capability to operators, not just into a program of record
• The procurement dysfunction that everyone in the room knows about and almost no one fixes
