Platforms & architecture
Lakehouse and warehouse foundations designed around how your business actually works — sensible medallion layers, clear ownership, and infrastructure that holds up as you grow.
Cairn Labs · Services · Data
Data you can build on.
From scattered sources to a single source of truth — we design, build and run the data platforms that turn raw information into decisions you can trust.
Vendor-neutral by default
What we offer
The full stack, end to end.
Whether you're starting from spreadsheets or scaling a platform that's outgrown itself, we work across every layer — from ingestion to the dashboard leadership opens each morning.
Engineering & pipelines
Reliable ingestion and transformation from every source you've got — APIs, databases, files, event streams — orchestrated, monitored, and built to recover on their own when something upstream breaks.
Analytics engineering
Clean, well-tested dimensional models and a semantic layer that gives everyone the same trusted numbers — defined once, documented, and reused everywhere instead of rebuilt in every report.
BI & dashboards
Reports people actually open — clear metrics, quick load times, and straight answers to the questions leadership keeps asking, built in Power BI, Looker or whatever you already live in.
Cloud platforms
Vendor-neutral by default.
We build where it makes sense for you — not where a licensing deal points us. Deep, hands-on experience across all three major clouds.
