継ぎ · FRACTIONAL DATA LEADERSHIP
Data that
holds together.
Tsugi Data gives growing companies a fractional Head of Data, plus a team that actually builds. Trusted metrics, a modern stack, and data that’s ready for AI, without the full-time hire.
SOUND FAMILIAR?
Most companies don’t have a data problem. They have a joining problem.
01
Nobody trusts the numbers.
Finance, Sales and Product each report a different revenue figure, and board prep takes a week.
02
Dashboards, but no decisions.
Dozens of reports, few owners, and no one sure which one is right.
03
AI plans, no foundation.
Leadership wants agents and copilots, but the data underneath isn’t ready for them.
SERVICES
Three ways to work together.
A full-time Head of Data costs $250K+ before their first hire. Get senior leadership for a fraction of that. Most clients start with an assessment.

APPROACH
A leader and a team, in one engagement.
Strategy firms hand you slides, and dev shops build whatever you ask for. We do both: senior leadership decides what matters, and experienced engineers ship it.
1
Assess.
Find where the joints are failing: definitions, models, ownership, tooling.
2
Build.
Fix the foundation, then put trusted metrics and AI workflows on top.
3
Lead.
Stay on as your fractional data leader, or hand off to the team we help you hire.
WHY “TSUGI”
