Flywheel Advisory

The people who build engineering
organizations, assessing them for you.

Flywheel Advisory pairs enterprise AI strategy with technology due diligence. For operators, that means turning AI from a slide into shipped capability. For investors, it means a clear-eyed read on the product, the architecture, and the team behind a deal.

The thesis

Most technology advice is written by people who left the arena years ago. Ours is written by people still in it — running an AI-native group of operating companies, shipping products every week, and living with the consequences of every architectural call.

That is the whole difference. When we tell an enterprise where to place its AI bets, it is because we are placing the same bets ourselves. When we tell an investor a codebase will not survive its next scale phase, it is because we have carried teams through exactly that wall. Judgment earned in production travels; a generic maturity framework does not.

What we do

01

AI strategy & digital transformation

We start from the business, not the model. Where does AI compress cost, unlock a new product, or change the operating model — and in what order? You leave with a sequenced roadmap your teams can actually execute, and the delivery discipline to make it stick.

02

Engineering organization design

Velocity is a function of structure. We shape team topology, hiring, and delivery practice so the org compounds instead of clogs — the same playbook used to lead 500-plus engineers at Adidas, adapted to your stage.

03

Technical due diligence

For PE, VC, and founders: a read written for a decision. Product, architecture, and team, assessed against the thesis and the price, with the deal-moving risks named plainly and the path to fix them costed.

04

Fractional CTAIO leadership

When you need operator-level technology judgment in the room but not a full-time hire — board prep, a critical build, a turnaround — we step in at CTAIO altitude and stay accountable to the outcome.

For operators

Enterprises betting on AI

You know AI reshapes your category. You need it to become shipped capability with measurable return — not a proof-of-concept graveyard. We bring the strategy and the execution discipline to get there.

For investors

PE, VC & founders

You are pricing a deal or defending a thesis. You need to know whether the technology and the team can carry the plan. We give you a clear, decision-ready read — fast enough for a live process.

Common questions

What does Flywheel Advisory actually do?

Two things that reinforce each other: we help enterprises design and execute AI strategy and digital transformation, and we run technology due diligence for private equity firms, venture investors, and founders. The same people who build and run engineering organizations are the ones who assess them for investors.

Who leads the engagements?

Thomas Prommer, our Group CEO and CTAIO, leads advisory personally. He was Global SVP of Engineering at Adidas (500+ engineers), CIO at Sweetgreen, and Senior Technology Advisor at Bain Capital. You get operator judgment, not a slide deck from someone who has never shipped.

How is technical due diligence different from a consulting audit?

Due diligence is written for a decision — invest, walk, or renegotiate. We assess the product, the architecture, and the team against the thesis and the price, then hand you a clear read on the risks that actually move the deal, not a generic maturity score.

Do you only work with large enterprises?

No. Enterprises come to us for transformation; investors and founders come to us for validation. Engagements scale from a focused two-week diligence sprint to a multi-quarter transformation program.

Tell us the decision you're facing.

A build to get right, a transformation to sequence, or a deal to de-risk — start here.
