Ship the platform
Scoped builds: ingestion, table formats, catalog, compute wiring, and the runbooks your team can keep.
91crew
We design and ship data platforms that stay operable — lakehouses, catalogs, and pipelines built with open formats and clear ownership.
Why work with a crew
Not a slide deck shop. Practitioners who own architecture and delivery together — from first catalog table to production syncs.
Open where it matters
Iceberg-first layouts, engine-agnostic catalogs, and escape hatches so you are not locked into one vendor story.
Product on the horizon
Consulting funds the craft. An open catalog / platform product is on the waitlist — same crew, same standards.
Services
High-intent work we take on for mid-market and product-led data teams.
Data engineering delivery
Pipelines, quality gates, and platform ops — from greenfield to rescue missions on fragile estates.
Lakehouse & warehouse modernization
Migrate toward open table formats, cut duplicate storage, and make analytics engines share one source of truth.
Catalog foundations
REST catalogs, governance hooks, and Spark / Trino wiring so tables are discoverable and safe to change.
Migration & hardening
Cutover plans, backfills, and reliability work so the new path is quieter than the old one.
How engagements run
A short loop from clarity to running software.
-
Discover
Sources, pain, constraints, and what “done” means.
-
Define
Architecture sketch, milestones, and success checks.
-
Build
Catalog, tables, pipelines, and the interfaces teams use.
-
Harden
Observability, ownership, and cutover without drama.
-
Hand off
Docs, runbooks, and optional retainers for evolution.
