Stenhus is a four-person consultancy in Rotterdam. We work with European product teams on the parts that matter — backend reliability, data architecture, and the unglamorous platform work that makes everything else possible.

Postgres at the centre, event streams where they earn their keep. We design schemas you can live with for five years and pipelines that don't quietly drop messages.
Observability, runbooks, on-call hygiene, and disaster recovery exercises that someone actually runs. We measure success by paging frequency.
"Stenhus joined us during a particularly rough quarter. Six months later our incident rate was down by two thirds and our engineers had stopped quitting. Worth every euro."
