Scale-ups · Segment 03

Clear Series B
without breaking production.

Interim CTO, pre-round architecture audit, tech due diligence, scaling. For scale-ups past the seed stage whose tech now has to hold.

Let's talk about your tech See handled cases

Who this is for

Past the seed stage. Before industrial scale.

Our ground: Series A–C scale-ups that have found their market, but whose stack is starting to dictate the roadmap instead of serving it. Teams fundraising and needing to convince funds of their tech's robustness. Not pre-seed. Not permanent hires.

How we engage

4 short formats, scoped outcome.

01 2–6 months

Interim CTO

The CTO is gone, the company is scaling, tech has to hold. We take over technical direction while you hire and hand over. Operational within 7 days — not 4 months of search.

02 Pre-Series B

Architecture audit

The code that got you to Series A won't get you to B. We map the debt, write the exit plan, estimate costs and timelines — with numbers you can defend in front of funds.

03 Commissioned by the fund

Tech due diligence

A senior external look at the tech of a target or a portfolio company. Report in 2–3 weeks with quantified risks, architecture assessed, team quality. For investors and acquirers.

04 Hypergrowth

Technical scaling

Get out of the monolith without breaking production, out of no-code that's become a blocker, open the stack to the 100 devs who are joining. Progressive refactor plan, no freeze on the product roadmap.

Pace

Short, targeted, defensible in front of a board.

Scale-ups don't have 6 months to spend on framing. Engagements of 2 to 6 months maximum, deliverables presentable to a board of directors or to investors.

Day 7

Interim CTO operational

2–3 wk

Full technical due diligence

2–6 mo

Typical interim CTO engagement

5 yrs

Target lifespan of code shipped

Real situations

What we've already held in scale-ups.

CASE / 01

“Our CTO is leaving, we just raised, we have to hold”

Interim CTO to keep technical direction while we search for the permanent replacement. Re-prioritization, team stability, continuity for investors.

Operational Day 7. Permanent CTO hired in 4 months.

CASE / 02

“We're preparing Series B, our code is a monolith”

Debt audit, progressive decomposition plan, cost and timeline estimation. Technical support in meetings with funds during due diligence.

Plan defensible in front of funds. Round closed.

CASE / 03

“Deep-tech — we have to exit the prototype”

AI-native architecture to go from notebook to production. Data pipeline, inference, observability, security. Stack ready for first industrial customers.

AI POC shipped to prod. Stack scaled to 100k+ calls/day.
