Flywheel Advisory

Proof first. The rest is
a conversation.

Flywheel Advisory pairs enterprise AI strategy with technology due diligence. Below is how that looks in practice: three representative engagements, each a real decision de-risked by people who still build and run engineering organizations for a living.

Selected engagements
  • Berenberg
  • McKinsey & Company
  • Bain Capital

Representative engagements

Three decisions, de-risked.

These are anonymized, representative patterns drawn from the service lines below. They show the shape of the work, not named-client results.

01
AI transformation For operators

A European private bank, from AI pilots to shipped capability

Challenge

A mid-size private bank had a dozen AI pilots running in parallel and nothing in production. Each business unit was buying its own tools, model spend was climbing, and the board wanted a single answer to one question: where does AI actually pay off here, and in what order.

Approach

We ran a value map across the operating model, ranked the use cases by return and feasibility, and killed the ones that were novelty. Then we stood up the delivery discipline behind the top three: clear owners, a shared model-governance layer, and a shipping cadence the teams could hold without us in the room.

Outcome

A sequenced roadmap the board could fund, two use cases live within the first quarter, and a consolidated tooling contract that stopped the sprawl. The bank left with the capability to run the rest itself.

02
Technical due diligence For investors

A growth-stage SaaS in a PE process

Challenge

A private equity fund was mid-process on a growth-stage SaaS asset. The revenue looked clean, but the deal team needed to know whether the technology and the engineering org could carry the growth plan the model was pricing in, and they needed the read inside a live timeline.

Approach

A two-week diligence sprint. We assessed the architecture against the next scale phase, read the codebase for the risks that move a valuation rather than a maturity score, and interviewed the engineering leadership to test whether the team behind the plan could actually execute it.

Outcome

A decision-ready report that named two real scaling risks and costed the remediation. The fund used it to renegotiate the price and build the fix into the first-100-days plan, instead of discovering it after close.

03
Engineering org design For operators

A scale-up whose delivery had stalled

Challenge

A venture-backed scale-up had tripled headcount in a year and watched its shipping velocity fall. More engineers, less output. Leadership could feel the org clogging but could not see where, and hiring more people was making it worse.

Approach

We mapped the team topology against the actual flow of work, found the dependencies that were serializing everything, and reshaped ownership so teams could ship without waiting on each other. The same playbook used to lead 500-plus engineers at Adidas, cut down to their stage.

Outcome

Clearer ownership, fewer cross-team blockers, and a delivery cadence that scaled with the headcount instead of fighting it. Leadership got a structure that compounds as they keep hiring.

The report named the two risks our own team had talked around for months, and it costed the fix. We repriced the deal on the strength of it.

How we work

The service lines behind the cases

AI strategy & digital transformation

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

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.

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.

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.

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.
