A CTO For Hire Who
Comes With A Build Team.
Hyperspark Studio gives non-technical founders a fractional CTO and the senior engineers behind them. Technical strategy, architecture, hiring guidance — and the product actually gets built while you look for (or skip) a technical co-founder.
What is a CTO for hire?
A CTO for hire — also called a fractional CTO or part-time CTO — is a senior technical leader you engage on contract instead of hiring full-time. They own technical strategy, architecture decisions, vendor and stack choices, and engineering quality, at a fraction of a full-time CTO salary or co-founder equity.
For most early-stage startups, a full-time CTO is premature: there is not yet enough engineering to lead, but the technical decisions being made now will be expensive to unwind later. A fractional CTO closes that gap.
Hyperspark Studio goes one step further than a solo fractional CTO: the technical leadership comes attached to a senior build team. Decisions do not stop at a slide deck — the same people who design your architecture ship it.
What Your CTO Engagement Covers.
- Technical strategy: stack, architecture, build-vs-buy, and AI decisions
- Product scoping that separates the fundable MVP from expensive distractions
- The build itself: web, mobile, backend, and AI shipped by senior engineers
- Investor and due-diligence support: someone technical in the room
- Hiring guidance when it is time to build your in-house team
Why Founders Choose A Fractional CTO.
No equity search required
Skip the year-long hunt for a technical co-founder. Get senior technical ownership now, and decide about equity hires from a position of strength.
Decisions plus delivery
A solo advisor hands you recommendations. We hand you a running product, because the CTO comes with the engineering team attached.
Senior judgment from day one
The costly mistakes happen early: wrong stack, wrong data model, wrong scope. Senior review before code is written is the cheapest insurance a startup can buy.
Fraction of the cost
A full-time US CTO runs $250k+ plus equity. A fractional engagement scales to what an early-stage company actually needs.
Investor-ready answers
Architecture docs, security posture, and roadmap answers that hold up in technical due diligence.
A clean handoff path
When you hire in-house, we hand over documented architecture and a codebase your team can run with — and help you interview them.
Frequently Asked Questions
What does a fractional CTO do?
A fractional CTO owns your technical direction part-time: architecture, stack choices, scoping, engineering quality, and technical hiring. At Hyperspark Studio the fractional CTO also directs our senior build team, so strategy and shipping happen in one engagement.
How is this different from hiring a technical co-founder?
Speed and reversibility. A co-founder search takes months and costs significant equity. A CTO for hire starts within days, costs a predictable fee, and leaves every equity option open. Many founders use us as the bridge to — or replacement for — that search.
How much does a CTO for hire cost?
Engagements are scoped per company and quoted after a short brief — typically a small fraction of a full-time CTO salary. Send us your stage and goals and we will respond with a concrete structure.
Do you also build the product, or just advise?
Both. That is the point: the same engagement covers technical leadership and the senior engineers who ship the product. Advice that ends in a shipped MVP, not a memo.
Can you support fundraising and due diligence?
Yes. We prepare architecture documentation, answer investor technical questions, and sit in on due-diligence calls as your technical counterpart.
What happens when we hire a full-time CTO or team?
We hand off cleanly: documented architecture, a production codebase in standard tooling, and help interviewing your hires. Some clients keep us for engineering velocity; others graduate fully in-house.
Do you work with US companies?
Yes — US and EU startups are our focus. We work in overlapping US hours, communicate async-first in English, and run weekly demos.
