It was co-founded by John Doyle who led Palantir’s national security business before starting this company. I think this comment best describes why Cape was started in the first place:
"Cape is not disclosing valuation, but it’s notable that the funding is coming at a time when startups building military, defense, and security services are getting increased focus and priority at a time when geopolitics are shifting.
While many of those shifts are playing out at a much higher level involving wars, espionage against officers and officials, and major contacts between outsized industrial entities, Cape’s products and its growth are one of the rare examples of how some of that evolution is playing out at a consumer level"

Ultimately, I still want to read up on them before considering making the switch.
