Founders now arrive at a first consulting call holding a working prototype that an AI coding tool produced in a weekend. The opening paid question has shifted to whether the code already in the repository will support paying users, a security review and an investor's technical due diligence.
The build came cheap; the review costs money and calendar time. AI coding tools pushed the price of a first build close to nothing and moved the spend into assessment, and that bill arrives where most founders keep no budget line. DoganTech sells the step as Vibe-to-Prod: a technical assessment of AI-generated code, a prioritised roadmap to production readiness, and the choice between having the hardening done for you and being taught to do it yourself. The cost is the part founders miss. Spend on strategy when what you own is a code risk and you pay for a roadmap, then pay again for the remediation, and the second bill is the larger of the two.
Everything below is a check you can run on your own company without asking anyone else. The sections come in the order the decisions arrive, because a reply that turns up a fortnight late costs more than the fee it was meant to control.
Four facts to settle before you approach anyone
Four facts decide whether a consultant can price advice at all, and you either have them or you do not.
You know whether the thing to be reviewed is a prototype with no users or a live system taking payments, since the second forbids the kind of rebuild the first permits. You can identify the one decision that cannot be undone cheaply, which is usually the data model, the hosting region, the licence terms of a core dependency or the payment provider. You have a monthly technology number split across hosting, tooling, salaried engineering and contractors. You can say which person inside the company owns the call, because a committee cannot receive advice.
Reyem Tech sets the three decisions with the highest long-term cost at the tech stack, the architecture pattern and the first two engineering hires, and its guidance to founders is to build what differentiates you and acquire everything else, on the grounds that authentication, payment processing, email delivery and hosting all arrive as proven services. That is the second fact above, stated by someone who has watched it go wrong.
Mind IT Systems makes the case that startups often lack the technical knowledge to settle infrastructure, software and security questions, and that consulting supplies that expertise without the overhead of a full internal team. That is fair, and it conceals a precondition: a consultant needs your numbers before advice can be priced. Bring the four facts and the first call is a scoping exercise. Bring nothing and you are paying senior rates for an education.
One more fact sets the order of work. An assessment commissioned six weeks before a raise settles different questions from one commissioned six months after it, so the timing of your round decides what you commission first.
What the first call has to produce
A first call that ends without a figure and a deadline has failed, however pleasant the conversation was.
The consultant asks which decision you are trying to make, and declines to address any technology question until you have settled on one. They can talk through two startups at your stage and say what had altered by the end of the work. They tell you which parts of your system they will not touch, and why. They offer a small first unit, priced as a half day, an assessment week or a fixed fee, before any retainer is mentioned. They give the figure without being asked twice.
DoganTech's UK practice runs thirty-minute and one-hour sessions with a free first call, which is a legitimate way to test fit before any commitment is made.
Read the model they sell while you are on the call. Vention, which reports having worked with more than 500 startups, runs delivery through a Delivery Manager and a Strategic Partner on the account, and says engineers begin within two weeks of signature. That is an embedded delivery model, and its price belongs in a different comparison from a half-day advisory rate; treating the two as a single number distorts both.
Before you compare two prices, settle which of the three models you want
Two prices compare only when they are charged against the same unit, and each of the three common models charges against a different one.
An advisory retainer is sold in days or half days and produces decisions, documented recommendations and second opinions. Ownership of the call stays with you, and the exit is cheap because nothing was built.
A technical assessment is sold as a fixed fee against a fixed deadline and produces a severity-ranked finding on code, architecture, security, scalability and accumulated technical debt. Zartis sets out system design, architectural style, scalability, security and technology stack as the key elements a consulting review covers, which is why the deliverable can be specified before you choose the firm. The engagement ends when the report lands.
An embedded delivery team is sold in sprint capacity or full-time-equivalent months and produces working software, with the build risk resting with the firm. It is also the most expensive model to leave, because the context and the code both stay with them.
The spread between the three is wider than most founders expect. Consultancy.uk reports that fees across the consulting market vary widely, that operational interim work stands at the bottom of the band, and that firms at the top treat their own fee structure as a trade secret. The cost base on the other side explains part of it: Starter Story's founder-reported figures place median startup costs for a technology consulting business near $10,000 and independent freelancers at $30 to $100 an hour, so a solo consultancy with almost no fixed cost can profitably sell a half day at a rate a firm with offices and a bench cannot match. Where two prices for one brief stand a factor of three apart, check the model before you check the rate.
On the contract page, before you sign
Five provisions decide what you keep when the engagement ends, and the rate is the least important of them.
Substitution comes first: whether the person on the contract can be replaced without your signed agreement, and on what notice. The unit of billing should be stated once and repeated on every bill. The intellectual property provision should assign the code and every document around it, so decision logs, architecture diagrams and threat models all transfer. The exit paragraph should say what is handed over on the first working day after termination. The standing agenda should say how often the engagement convenes and which document it produces.
TST Technology's CTO-as-a-service process finishes with knowledge transfer and documentation and treats intellectual property and confidentiality as a standing question, which is the right instinct. The test is whether the wording still works on the day the consultant takes another client.
In the first month, read the documented output
If the only thing your consultant produces in thirty days is a conversation, you have paid for a sounding board and the service has not started.
By day ten there should be a decision recorded on paper that says when it was taken and who took it, because a recommendation with no day against it cannot be reviewed later. The consultant should have met the engineers who will live with the consequence, in a room without the founders. One risk should have moved from unquantified to sized, with a number against it. The first bill should match the unit on the contract page.
How to test if the engagement works
The ninety-day point separates an engagement that is working from one that is being tolerated.
The decision log should contain at least three calls that changed what the company was going to do. The roadmap should carry a revision trigger, meaning the event that would force it to be redrawn. The engineering team should be able to explain one architecture choice and the reason behind it, in their own words and without the consultant in the room. The exit test is simple: ask for the handover pack today and see whether it arrives complete inside a week.
When to extend an engagement, and when to stop
Extending pays off only when the decisions still ahead are larger than the fee. Two gates settle it:
- If the items left on the decision log are smaller than the last three already closed, the engagement has done its work and the next payment buys comfort.
- If a funding round, a regulated market entry or a first enterprise contract falls within two quarters, the next ninety days hold more decisions than the last ninety did, and a short extension usually pays for itself.
The work of choosing a consultant is mostly work you do before the first call. Four facts, one model, five provisions and three gates settle more than any pitch the firm can send you.
