How we work

We're not an agency. We become part of your team with flexible engagement models.

Paid Consultancy

Traditional engagement with day rates or project fees. Best for funded startups with specific, well-defined projects.

Equity Partnership

We work for ownership. Best for pre-funding startups or founders seeking a genuine technical partner.

Hybrid Model

Reduced rates plus equity upside. Our most common arrangement for long-term partnerships.

What we bring

Twenty years of building platforms together means we've seen it all.

Systems Architecture

Scalable, maintainable systems that grow with you from MVP to millions of users.

Full-Stack Development

SaaS, mobile apps, web platforms, and even console games. We've shipped them all.

Funding Expertise

We've been through it. Technical due diligence, investor conversations, and exit negotiations.

Full Support Team

Beyond code: product strategy, hiring, operations support as you scale.

Based in the UK

Our team is distributed across South Wales and Yorkshire. We work with founders globally, but there's something about a proper cup of tea and a face-to-face chat that Zoom can't replace.
