The problem

A full-time CTO costs €150k a year. Your product has to exist in three months.

Between the agency that bills without owning the outcome and a hire that takes six months, a third path was missing.

You have a validated idea, no technical team.

You know what the market wants, but nobody internally can arbitrate stack, data and AI decisions.

You have a team, no technical leadership.

Developers ship without a roadmap or architecture review. Technical debt piles up before Series A.

You are raising soon and need a credible demo.

A solid prototype, an architecture that survives due diligence, and real metrics to show.

What we do

Three levers to go from idea to product.

One team, three engagement modes — matched to your company's maturity and the stage of the project.

01

Fractional CTO

Senior technical judgement, 1 to 4 days a week.

We structure your stack, your hiring and your roadmap without you renting a full-time profile. You stay in control of the product; we de-risk the technical decisions.

  • Outsourced technical leadership
  • Developer hiring & mentoring
  • Weekly product roadmap & trade-offs
  • Architecture and security reviews

For funded startups and SMEs going through digital transformation.

02

B2B / B2C SaaS prototype

From idea to working product in 60 days.

Business scoping, design, Data & AI model, rapid prototyping. The Workfutur average is 60 days to a genuinely usable MVP — not a mockup, a product in production with real users.

  • Business scoping in 5 days
  • Scalable architecture from day one
  • Visible weekly iterations
  • Production deployment included

To validate a market, prepare a raise or launch a new product line.

03

Full-stack development

Design, build, Data & AI integration, production.

Maintained, documented code ready to grow with your team when you build it. We work in TypeScript and Python, with proven data pipelines and AI components.

  • Full-stack TypeScript / Python
  • Data pipelines & AI (LLM, scoring, RAG)
  • Documented handover
  • Stripe, Google Workspace and ERP integrations

To industrialise a prototype or reinforce an existing team.

Our method

A prototype in 60 days, the intellectual property from day one.

The promise holds because scoping is short, iterations are weekly and visible, and IP transfers from the first euro invoiced.

1

Express scoping

Week 1

A two-day workshop with the founder. Scope, risks, success metrics, delivery plan. Quote signed within 5 days.

2

Working prototype

Weeks 2 – 6

Short, visible iterations. Weekly code review. Production deployment on scalable infrastructure (Vercel · Supabase · European hosting).

3

IP transfer

Weeks 6 – 8

Repositories, cloud accounts, design system, technical documentation: everything moves to your entity from the first euro invoiced.

4

Growth & scale

Weeks 8+

Either the engagement ends cleanly, or we move to a fractional CTO retainer to steer growth and hiring.

Selected work

About ten projects a year. Seven examples.

10+ MVPs shipped across B2B and B2C, from FinTech to EdTech via AI, media and social impact.

The founder

His view: a founder doesn't need one more consulting firm. They need someone who writes code, makes the calls and owns the technical decisions with them — then hands over the keys.

John-Guy Park
Founder & fractional CTO

A serial entrepreneur, John-Guy leads Workfutur's technical delivery and client engagement from Paris and Singapore. He has designed, built and shipped more than ten B2B and B2C SaaS products, from PropTech to FinTech and applied AI.
