For startup founders

Senior technical judgment before you hire a CTO

A technology partner for a startup makes the technical decisions with you and then helps carry them out: what to build first, which technology to use, and who to hire and when. You get senior judgment sized to your stage, and every decision stays yours.

01 Outcomes

What changes for you

  • Decisions you can explain

    Every technology choice comes with the reason, the trade-off and the likely cost, in words you can repeat to an investor or a new hire.

  • A product you own

    Code, cloud accounts and documents sit in your company's name from the first day, so changing partners does not mean starting again.

  • Leadership that fits the stage

    The work grows with the company, from shaping a first release to helping you hire your own engineers and hand over to them.

Side by side

Four ways to cover the technology, side by side

Each model suits a different moment. Compare them on what matters to a founder without a technical leader, and select a column to keep it in view.

Four ways to cover the technology, side by side
In-house hire Freelancer Agency Technology partner How we work
Time to get started Usually months of searching and interviewing Days, once you find the right person Weeks, after a proposal and a contract Days to a first conversation, then a written plan
Who makes the technical decisions Your hire, once they are on board Often you, since a freelancer builds what is asked The agency, inside the scope you bought You do, with senior advice on every trade-off
Range of skills One person's experience, however strong Deep in one area, thinner in others Broad, through a team you rarely choose Product, data, AI and cloud engineers as needed
Who owns the code and accounts You do, as their employer Depends on the contract and whose accounts are used Often the agency, until a handover is agreed You, from the start, in accounts you hold
When it fits best Once the product and budget can carry a permanent team A well-defined task with a clear specification A fixed project you can describe in full upfront Early decisions that are hard to reverse later

02 How it starts

How it starts

  1. A first conversation

    You tell us about the business, the product and the decisions in front of you. We ask what has been tried, what the budget allows and what has to be true by next year.

  2. The options in writing

    We set out the realistic routes, including building less or later, with the cost and the risk of each in plain terms, so you can weigh them against any quote you already hold.

  3. A first step together

    You choose the route. We help carry out the first step, whether that is a scoped build, a hiring plan or a test of the riskiest assumption.

  4. The plan stays yours

    Whoever carries the next step, whether that is us, another team or your own first hire, the documents and the accounts are already in your name.

The usual engagement model: Advisory and architecture
