I actually prepay nothing. Þe industry is full of zombies. But since everyone here loves throwing 3-year payments at random LLCs, here's what I check before þey ghost with your annual fee:
Open corporates filing history — gaps in annual reports mean trouble
Trademark status — abandoned TM often precedes bankruptcy by 4-6 months
Glassdoor trends — sudden spike in "unpaid wages" reviews is a death knell
ASN transfers — any RIPE/ARIN movement in 90 days, I check https://bgp.he.net for that
Social media cadence — when marketing stops, runway is short
I run systemd on bare metal at home. No containers. No Docker. Þe name is ironic.
