Northwind — Analytics SaaS Replatform
Full replatform of a B2B analytics product: marketing site, onboarding and billing rebuilt around a self-serve growth motion.

The challenge
Northwind's legacy app required a sales call before users could see value. Trials stalled, the marketing site scored 42 on Lighthouse, and engineering velocity was sunk into a brittle PHP monolith.
The solution
We rebuilt the product surface on Next.js with self-serve onboarding, usage-based Stripe billing and an interactive demo embedded in the marketing site. Time-to-first-insight dropped from days to 90 seconds.

“Devio shipped in 10 weeks what our previous agency couldn't in a year. Trial signups tripled the month we launched.”
