Service 03
Fractional CTO
Senior technical and operational leadership without the full-time hire. I sit on your side of the table for architecture, AI strategy, vendors, and hiring.
What it is
Some companies need a senior technical voice in the room every week without a full-time CTO on the payroll. That is what this is. I sit on your side of the table for architecture, AI strategy, vendor choices and hiring, and I stay long enough to be accountable for how those decisions turn out rather than handing over an opinion and leaving.
It runs as a monthly retainer. What you are buying is a rhythm rather than a document: weekly working sessions, ownership of the technical roadmap between them, and someone reachable when a decision cannot wait a week.
What’s included
Weekly working sessions with you and whoever else needs to be in the room that week
Architecture and roadmap ownership, so one person is accountable for the shape of the system rather than three people half-owning it
Vendor and hiring evaluation: what to buy, what to skip, who to hire and what to ask them
Direct async access in between, so a decision does not sit for six days waiting for the next call
What is not included is hands-on delivery at volume. I will prototype to settle an argument, read your code and review your team’s work, but if the plan calls for weeks of implementation that belongs with your engineers or with an Automation Build Sprint, and my job is to make sure it is the right thing being built.
How it runs
Getting current
I read the system, the backlog and the contracts, and talk to the people running the day to day. By the end of the first month I can argue for or against a decision without asking you to re-explain the context each time, which is the whole point of a standing arrangement rather than a series of consultations.
The weekly rhythm
A standing session each week: what is in flight, what is about to be decided, what I think and why. Between sessions I am reachable directly, and I would rather be asked a five-minute question early than review a finished decision late. The scope is reviewed openly as the work changes.
Who it’s for
Founders and operations leads carrying technical decisions they would rather not make alone. It fits where those decisions are frequent and expensive, the stack is growing faster than anyone is steering it, and the volume of hands-on work does not yet justify a full-time hire.
It is the wrong choice if what you need is someone building. A fractional arrangement gives you judgement, not capacity, and a team that needs full-time hands-on delivery will be frustrated by an advisor no matter how good the advice is. Hire in-house for that, or scope the work as a build sprint. It is also the wrong starting point if you do not yet know which problems are worth solving with software, which is what the AI Ops Audit is for. I will say so on the call if that is what I think.
What I bring to the table
The technical half of this is the part people expect. The other half is having sat in the operational and board seats being advised, which changes what advice is worth.
Operations & Finance
Treasury, OTC trading, KYC and AML compliance, institutional operations. I’ve run the processes I now automate.
Leadership
Fundraising, investor relations, agile delivery, cross-functional teams. Comfortable in the boardroom and the terminal.
Concretely: I am CTO and co-founder of Crumbless.ai. Before that I ran institutional operations at Celsius Network, a $10B AUM platform, where I personally negotiated over $1B in loans. I founded Bitquinox, an OTC desk that settled more than 3,000 trades. I was COO of DATE&GAME, covering treasury, compliance and investor relations. So when the question is whether a control is worth the friction, or what a lender or an investor will actually ask, that is not a hypothetical for me.
Common questions
How is a retainer scoped, and how does it end?
Scope and monthly commitment are agreed up front, before anything starts, and there is no lock-in. If the arrangement stops earning its place, you say so and it ends. I would rather you leave when the value runs out than stay because of a contract.
Do you work remotely?
Yes. I’m London-based and remote-first, with on-site workshops in and around London by arrangement.
What happens on the intro call?
Thirty minutes. You describe how the work flows today, I ask questions and give you my honest read, including whether automation is worth it for you yet. You leave with next steps either way. No deck, no pitch.
Start with a thirty-minute call.
No deck, no pitch. You describe the decisions in front of you and leave with my honest read either way.
