Forty years in data. Sixteen where being wrong is expensive.

I’m Guy Wilnai. I founded Datagize so that the person you meet is the person who builds your data platform — not a partner who introduces you to a delivery team.

Since 2011 I have worked almost entirely on data warehousing and business intelligence inside banking, insurance, government and manufacturing — the places where being wrong is expensive and change control is not optional.

Where the forty years went

The short version, most recent last.

Oracle · Manufacturing EBS

Led the Work in Process module

An early team member on Oracle’s manufacturing application, and built a custom asynchronous transaction manager for a Fortune 50 automotive company.

Before the tools existed

Custom sales compensation systems

Built from scratch, years before off-the-shelf products covered the problem.

Enterprise programs

Master data management

Solutions and data architecture, governance, ETL, program management and KPI development for Fortune 500 clients.

Since 2011 · nearly sixteen years

Data warehousing and BI, full lifecycle

Multi-phase programs across banking, insurance, government, manufacturing and high tech, including cloud migrations end to end.

Most recent

A multi-entity general ledger hub, inside a Tier-1 financial institution

In production, under full change control, built and validated without access to customer records. 50% faster delivery, measured. Read the case study

How I work

Three commitments you can hold me to, rather than three adjectives.

I do the work

You get the founder on the engagement. There is no bench, no handover after the sale, and no junior team learning your business at your expense.

Vendor-neutral, and specific

No reseller margin and no platform loyalty — but I will name the stack I would use and tell you exactly why. Neutrality is not the same as vagueness.

Built for change control

If your review board, security questionnaire and test-evidence requirements are the real timeline, we design for that from the start rather than treating it as friction.

How engagements are staffed

Datagize is a senior-only practice. I lead every engagement. When one needs more hands, I bring in practitioners I have personally shipped production systems with — hand-picked for the work in front of us, not assigned from a bench.

Who will be on my team?

You will know before you sign. No one on your engagement will have fewer than fifteen years in the field — there is no pyramid and no junior consultant learning your business at your expense. If the scope grows, the team grows with people I have worked beside, and you meet them first.

What if you are not available?

The platform does not depend on me being in the room. Every database object is version-controlled, every deploy is scripted, and schema drift is detected automatically. When your auditor asks what changed and when, the system answers — not a consultant’s memory.
