Nothing ventured,
nothing gained.

We’re SIDEKICK, a venture studio built to move with founders – stride for stride. With capital, strategy and creative firepower, we help founders build better, faster and stronger.

The ultimate wingman

Like all great sidekick partnerships, progress happens when the right energy collides. We don’t just advise – we build together.

Our 18-month venture process is battle-tested in the real world, giving founders the structure, speed, and clarity to launch and scale with success.

Our thesis

Over the next decade, we’re going to need agile, quantum and AI-native solutions that can be rapidly prototyped and deployed through mission-driven startups across three key sectors.

> Cyber

> Defence

> National Security

At the heart of the UK’s cyber future

Based in Gloucestershire, SIDEKICK sits at the centre of the UK’s leading cyber cluster – home to GCHQ, 7,000+ specialists and the emerging Golden Valley cyber campus. That means we’re perfectly placed to co-build the next generation of high-impact startups in cyber and deeptech.
