01 / Lead · Fractional & embedded leadership

Senior operators, in the room for the stretch that matters.

We join your team and pair clear strategy with hands-on delivery — turning hard growth into steady momentum. Embedded, not advisory: we own the outcome beside you.

Two founding partners · in the room from day one · no hand-offs
Why this stage is hard

The gap between rounds is where momentum is won or lost

It's rarely the product. It's execution — and it's where we do our best work. The honest picture:

58%

of Series B companies never reach Series C — and it's rarely the product that holds them back.

856

days is the median stretch between rounds, where momentum is the rarest currency you have.

50%

of senior leadership hires misfit within 18 months. A fractional start de-risks the call.

How we help

Strategy and delivery, from one team

Because a plan you can't ship isn't worth much — and building without a plan rarely scales. We do both, beside you.

Strategy & diagnostics

An honest, forensic read on where execution actually breaks — and a plan everyone can get behind, not a deck that gathers dust.

Fractional leadership

Senior CTOs, COOs and CHROs who embed with your team and bring momentum from day one — the seniority you need, scaled to what you can carry.

Engineering velocity

We clear the technical debt and structural friction that's in the way, and get your team shipping with confidence again.

Systems that scale

Process, architecture and operating rhythm that hold up under growth — so the next stage doesn't break what the last one built.

Who you'll work with

Most firms fix culture or code in isolation. We think they're the same problem.

Ian clears the technical friction so your systems can function. Toni clears the cultural friction so your people can lead. You work directly with both — no account managers, no hand-offs.

The Tech Stack

“Destroy all bad software.”

Bad software isn't an inconvenience — it's a malignancy that quietly drains your capital, speed and morale. I give a clinical, forensic audit of your stack and the unvarnished truth about what's broken. I don't just fix code; I break down the technical barriers to operational integrity.

The People Stack

“Eliminate the friction between people & systems.”

What looks like a “people problem” is usually a design flaw — misalignment, unspoken expectations, systems that weren't built for the weight of the company. My superpower is naming the thing beneath the thing, with clarity, empathy and just enough humour to make the hard truth land safely.
