How we work

Two layers. One senior owner.

Most of what we sell is recurring — retainers and productised care. On top of that, a narrow band of specialised projects.

What we do

Two pillars. Built for production.

Innovation
We build the hard stuff.

AI agents, computer vision, edge AI, robotics, simulation, and immersive experiences — designed to work in the real world.

Who it's for

Two audiences. One senior owner.

Founders & scaleups

Seed / Series-A without a full-time CTO.

You have 10–60 engineers and a real business, but hiring a full-time CTO at the right seniority is a 12-month search. We run tech + product on retainer while you decide.

PE & VC operator-buyers

Post-close, you need senior technical ownership from day one.

Pre-close: Technical Due Diligence. Post-close: Team Build & Transition or continuous Fractional CTO / CTPO. Same senior owner across the entire lifecycle.

Why teams choose Gespona Tech

01

Senior-only, always

Every engagement is led and delivered by a senior with 25+ years of production experience.

02

We ship, not just advise

Decks are a means, not the deliverable. Code, systems, and decisions are.

03

Transparent pricing

Entry, Standard, and Premium tiers published for every recurring offer. No "contact for pricing" mystery.

04

Solo + trusted network

Gerard plus three vetted senior partners — 68 deployable hours a week, never single-person-dependent.

05

Built for the real world

Production over prototype. AI that ships, not AI that demos.

06

Your team gets stronger

Knowledge transfer and handover playbooks are deliverables, not afterthoughts.

How we work

1
Listen

Understand goals, constraints, and the real workflows behind the brief.

2
Frame

Turn the brief into an execution-ready plan with clear scope and trade-offs.

3
Build

Deliver hands-on with senior ownership and weekly written updates.

4
Hand over

Transfer knowledge, code, and decisions to your team — by design.

The person who scopes the work is the person who delivers it. Always.
