They're silently making sales around the country. I've seen their installations at a few places in the Bay Area. My guess, tacitly acknowledged by a friend I bumped into several years ago who was a sale rep, is that because their technology doesn't have strong patent protection (just a productization of long-existing tech), and the margins slim to none, they're careful to avoid inviting competition, and presumably can't afford to burn much money on flashy campaigns, anyhow. Hopefully the outages will give them a bump as it seems like precisely the sort of no-nonsense solution to on-site power generation needed by light industrial customers, such as labs and smallish data centers.
