A Small, Stable Team
Ellie is built by a Helsinki-founded team that's stayed close-knit through 60+ enterprise rollouts -- the same people who shipped last year's release are shipping this one.
That continuity means the person who answers your integration question next month probably wrote the code for it, not a support rotation reading from a ticket.
