Most early technical damage is not bad code. It is three months spent on a decision nobody in the room was qualified to make.
What we can show you
A consultant hands you options. A fractional CTO picks one, writes down why, and is accountable for how it turns out.
Five things, in the order founders usually need them. Architecture and build-or-buy decisions — what you build, what you rent, and what you postpone. Vendor choice and control — reading proposals, setting acceptance criteria, catching the estimate that is optimistic by design. Hiring — role definition, technical interviews, and a first-90-days plan. Technical due diligence — for your investor or for an acquisition you are considering. Budget and priority — what gets built this quarter and what does not.
It is part-time on purpose: most early companies need a few hours of senior judgement a week, not a full-time salary and an option package.
When there is no technical co-founder; when a vendor is proposing something you cannot evaluate; when an investor asks for technical due diligence. If you already have a strong lead engineer, what you probably need is a sounding board — cheaper, and we will say so.

Three different products that get confused constantly, and the cheapest is not always the right one.
We are a development studio. That creates an obvious conflict, so the rule is on the page rather than in the small print.
If your fractional CTO recommends a build partner, alternatives are named in writing and the reasoning is yours to check. Recommending someone other than us is a normal outcome.
If you do choose us to build, the CTO role moves to an independent person or the retainer is discounted for the duration — you should not pay us to supervise ourselves.
Every significant decision gets a short record: options, trade-offs, what we chose and what would make us change our mind. It survives the engagement and the next CTO.
That record is what makes technical due diligence painless a year later.
One scheduled call a week, an agreed decision queue, and asynchronous answers inside your working day. Belgrade overlaps US East by four to six hours.
Hours are capped and reported: you see where the time went.
Code quality, architecture, team, security posture and a prioritised risk list — for an investor, or before you acquire someone else's product.
Delivered in a week, in a form an investment committee can read without a translator.
Four things we can prove, rather than four adjectives.

Alternatives in writing, and the CTO role handed over or discounted if you pick us to build. Written on the page, not buried in an engagement letter.

Cash only, cancellable monthly. Advisory equity is how early cap tables get complicated for work that lasted one quarter.

230+ projects means the vendor proposal in front of you looks familiar, including the parts that are optimistic by design.

Past roughly 40 hours a month, a fractional CTO is a worse deal than a full-time one. Saying that costs us a retainer and saves you a year.
Industries
The decisions differ by domain: compliance in fintech and health, integrations in logistics, unit economics in marketplaces.
Six answers that usually replace a discovery call.
Core covers up to 20 hours a month, Pro up to 40. Beyond that a full-time hire is the better deal and we will tell you so.
No. Cash only, month to month. Advisory equity complicates a cap table for work that often lasts a quarter.
The engagement letter prevents it: alternatives are named in writing, and if you pick us to build, the CTO role moves to an independent person or the retainer is discounted.
Yes: code, architecture, team, security and a prioritised risk list, $4,490, delivered in a week in a form an investment committee can read.
Yes: role definition, screening, technical interviews and a first-90-days plan for whoever you hire. Included in Pro.
Possibly not. What you may need is a sounding board a few hours a month, which is cheaper. We will say which after the first call.
