CTO-in-a-box · for non-tech founders

Hello, future founder.
You built the MVP.
All you're missing is a CTO to scale and secure it.

Stop scrolling through resumes you can't fully judge. Stop burning runway on a full-time exec. For €27, you get the same thing a senior CTO would hand you in their first two weeks — how to scale your MVP safely, lock down your data, and ship to real customers without things breaking.

How it works

Three steps. Thirty minutes. The CTO playbook your MVP needs to grow.

  1. 01

    Tell us what you've built.

    Two sentences about your MVP. We figure out the kind of product you have — SaaS, mobile app, marketplace, game, device companion — and skip the irrelevant questions. No 80-question survey for a 6-question idea.

    Reads your idea · picks the right questions

  2. 02

    Answer a handful of plain-English questions.

    How many users do you expect? Do you handle payments? Will customers upload private data? Every answer becomes a decision a CTO would otherwise make for you — written down, justified, ready to act on. Autosaves as you type.

    Plain English · resumable · works on your phone

  3. 03

    Pay €27. Your CTO's first two weeks land in 30 minutes.

    We deliver the technical plan, the security checklist, the things to fix first, and the things never to break — emailed as a zip and pushed straight to your GitHub. Hand it to your developer or your AI coding agent, and they ship without guesswork.

    Email + GitHub PR · refundable for 7 days

Pushed to your repo

Your developer starts shipping before lunch.

Connect your GitHub once. We open a pull request with the whole plan inside it — your developer reviews, merges, gets to work. No dragging files around. No back-and-forth.

  • A real pull request. Reviewable, mergeable, your team can comment on it like any other change.
  • Minimum access. We ask permission for one repo only. Nothing else on your account.
  • AI-agent ready. Tools like Claude Code and Cursor pick up the rules and start shipping with senior supervision baked in.

What's coming

We didn't stop at the blueprint.

ctobox is becoming the full founder bench — the docs, the numbers, the deck. All in the same voice as your scaffold.

  1. NextIn design

    Founder tech reference

    A pocket-sized guide to every choice in your blueprint — what each piece does, why we picked it, what to ask your engineer about it. So you can talk to your team like you wrote it.

  2. SoonIn design

    Business plan, drafted with you

    Market, model, GTM, unit economics, hiring plan. Same opinionated voice. Same 30-minute promise.

  3. AfterIn design

    Investor pitch deck

    Ten slides, your story, written in the language investors actually fund. Auto-rendered to a deck you can edit.

You have the plan. Now what?

Four ways to take your MVP to market.

The CTO playbook is yours. Pick the path that fits how you work — or talk to us and we'll take your MVP all the way to real customers, end to end.

  1. 01

    Hand it to your developer.

    The freelancer or engineer you already have. Every decision is justified in plain language — they stop guessing, you stop paying for guesswork.

  2. 02

    Hire confidently.

    Now you know exactly what good looks like. Interview candidates against the plan instead of nodding along to a resume you can't fully judge.

  3. 03

    Point an AI agent at it.

    Tools like Claude Code or Cursor read the plan, follow the rules, and ship the work. Your AI coding agent has senior supervision baked in.

  4. 04

    Let us take it to market.

    Architects, engineers, business consultants — the team that wrote the playbook. We turn your MVP into a product real customers pay for.

Build with us

Don't want to manage any of this? We'll take your MVP from here and ship it to real customers.

From the first paying customer to thousands of them. Architects, engineers, and business consultants — the same team that wrote the playbook. Drop a note, we set up a quick call and scope it together. No retainer drama.

hello@ctobox.tech

One line, one idea, one outcome. We'll reply within a working day.

Pricing

27 for your CTO playbook.

One charge. The same plan a senior CTO would hand you in their first two weeks — for less than the cost of a single hour of their time. Pro and Agency add GitHub delivery and a recurring quota for teams that ship often.

FAQ

Honest answers before you spend €27.

If your question is not here, write to us — the address is at the bottom of the page.

I'm not technical. Will I understand what I get?
Yes — that's the point. The plan is written in plain English first, with the technical detail underneath for whoever you hand it to. You'll know what to build next, what to lock down for security, and what to ask your developer to do. No jargon you have to Google.
Why not just hire a CTO?
Because a full-time CTO costs €120k–€200k/year and takes 3–6 months to find. Most founders at MVP stage need a plan, not a person. Once you have the plan and traction, you can hire confidently — you'll know exactly what good looks like. Until then, €27 beats burning your runway.
Why not just ask ChatGPT?
You can. You'll get a generic answer and you won't know which parts to trust. The €27 buys a complete, opinionated plan written for your specific idea — security, architecture, what to build first, what never to break — with the rules a senior CTO would refuse to skip. Think of it as 20 years of experience compressed into 30 minutes.
What is actually in the plan?
A complete set of docs covering: how to build your MVP into a real product, the security checklist, the sprint plan ordered by priority, one task-per-file your developer or AI agent can act on, runbooks for when things break, and the end-to-end customer journeys. All written specifically for your idea — not a template.
How many questions do I have to answer?
Depends on what you're building. We read your two-sentence description and ask only the questions a senior CTO would actually need answered — usually 8 to 20. Mobile app? Different questions than SaaS. Marketplace? Different again. The form adapts so you don't waste time.
How long does it take?
Under 30 minutes end to end. Answering questions is typically 10–20 minutes; checkout and the AI run are a few minutes more. You receive everything in your inbox — and a pull request in your GitHub — the moment it's ready.
How does the GitHub delivery work?
Install the ctobox GitHub App on one repo. We open a pull request with the entire plan — every file, ready for your developer to review and merge. We only ever write to repos you explicitly grant.
Which AI writes the plan?
Claude Opus, one of the strongest models on the market today. But the AI is just the engine — what makes the output worth €27 is the playbook we've spent months building on top of it: 20 years of CTO experience baked into the instructions.
Can I edit what ctobox sends me?
Yes. The output is plain text files. You own it outright. Edit anything, drop the parts you don't need, hand it to a developer or to an AI coding agent like Claude Code or Cursor.
Who owns the IP?
You do. The blueprint is yours from the moment the charge clears. We retain no rights and never share your input or output with anyone outside the AI providers we use to generate it.
What if I'm not happy?
Seven days, no questions, full refund if you haven't downloaded the plan. After download, we handle refunds case by case — write to us and we'll work it out.
Can my team share access?
Team seats land with the Agency tier. Pro users get unlimited plans for one founder. Agency adds multi-seat access and team admin.
