Welcome to Wh4

At WH4 Ltd, we invest in the exceptional. Our mission is to identify and support the brightest founders building transformative, high-tech ventures—particularly in artificial intelligence and sustainable technologies that protect our planet and improve lives.

We are currently investing in a number of groundbreaking startups harnessing AI to revolutionise healthcare and medicine. From early diagnosis and personalised treatment to smarter systems and life-saving innovation, these ventures are shaping a future where everyone can live longer, healthier, and more fulfilling lives.

With over 25 years of experience acquiring, growing, and exiting highly successful businesses, we bring more than capital. We bring entrepreneurial firepower. We know what it takes to build something that lasts.

Whether we invest directly or raise capital through our trusted network, we deliver far more than funding. We provide:

• Back office infrastructure – streamlined operations, compliance, and administration

• Accounts & financial management – robust reporting and planning

• Brand, marketing & communication strategy – cutting through the noise

• Board-level support – seasoned non-executive directors and strategic advisors

• Growth planning – refined strategies shaped by real-world success

• Entrepreneurial insight – because we’ve walked the same path

WH4 Ltd exists to back visionary founders solving the world’s toughest challenges through deep tech and human ambition.  If your purpose is bold and your technology can drive positive, lasting change, we’re ready to help you build.

Let’s shape a smarter, healthier, and more sustainable world—for us, and for every generation to come.
