Growth is a thousand small dots, placed deliberately.

Brosnan Growth gives founders senior technical and financial leadership without the full-time cost — connecting the details until the whole picture resolves.

Start a conversation What I do

Services

Senior leadership, engaged at the fraction you actually need.

01

Fractional CTO

Architecture, hiring, roadmap, and technical due diligence. Engineering leadership that keeps shipping honest and debt deliberate.

02

Fractional CFO

Runway modeling, pricing, unit economics, and investor-ready financials. The numbers behind every confident decision.

03

Growth Systems

Activation, retention, and revenue loops — instrumented, measured, and compounding. Growth as an engineered system, not a wish.

Approach

Point by point, until the picture is undeniable.

i.

Observe

Two weeks inside your data, code, and books. No recommendations until the picture is real.

ii.

Compose

A focused operating plan — the fewest interventions with the largest compounding effect.

iii.

Place

Hands-on execution alongside your team: hiring, architecture, models, and metrics that stick.

iv.

Step back

Systems documented, team leveled up, and a clean handoff. You keep the picture; I keep the invoice small.

“Up close it's just dots. Step back, and it's a business that works.” — The Brosnan Growth thesis
