Leif Capital is an independent investment bank specialising in energy, transport, materials and manufacturing. Established in 2002, we have unrivalled experience in the financing of sustainable innovation and draw on a global network of financial and corporate investors.


We are inspired by symbiosis in nature.


Athletic beasts and nimble birds can get along very well. But nature is also brutal and unforgiving. So is sustainable innovation.

We provide our clients the strategies to prosper in the ruthlessly demanding innovation economy.


If you are an athletic beast or a nimble bird ambitious to survive and flourish, we can help. All species of innovator are welcome.




Financing sustainable manufacturing, energy and transport is what we do and what we’ve done for the last 20 years. We are proven symbionts in the innovation jungle. We have learnt from our failures and prospered from our successes. 


Capital Raising

If you need capital for growth, we will find you investors that provide expertise and access to markets, as well as money. The investor network available to our clients is global and draws upon our experience and success in Europe, North America, and Asia.

We differentiate between slow money, but slow money that is worth waiting for, and time-wasting “innovation tourists” who should be avoided.

We advise our clients not just on who they should be approaching, but how they should be approaching them; rigorously preparing them to answer all the questions that investors ask and should ask about financial and business models, technology, routes to market and exit strategies.

Investment Advisory

Private and public capital now has unprecedented appetite for investing in industrial sustainability. We seize this historic opportunity.

Innovation agencies, family offices, financial and corporate investment companies draw on our extensive knowledge of sustainable investment strategies among their actual and potential peer groups.

Our services – tailored to our clients’ needs - include benchmarking, sourcing of co-investors and deal-flow, execution and management of investments (including portfolio company acceleration and sale). Sometimes, we simply need to convene our investors, introduce them to each other, and explore the potential for collaboration.


Sometimes you just need to focus on winning and servicing clients.  Raising or investing capital has already happened or can wait.


Leveraging our global network of corporations and service providers, we can quickly identify the best business models and the right routes to market.


Having clients, and a pipeline of potential clients, is typically the best foundation for raising and/or investing capital.

  Investment Themes  

In our experience, the breakthroughs we’ve seen in mobility and energy are mostly underpinned by advances in materials. The path to Net Zero transport and power requires further material innovation combined with reliable and scalable manufacturing.

Advanced Materials 

Mankind is on the move. Leif Capital works with companies who are delivering the new infrastructure, technology and business models needed for e-mobility - drones, autonomous vehicles, etc - and who are enabling the smart cities of the future.


 The science is clear, the market opportunity is accelerating and the transition to a net zero economy will provide excellent returns for investors. We are active from hydrogen to renewables to energy storage to carbon capture.

Net Zero

Approximate isn’t good enough. We can’t think of a sustainable technology that isn’t advanced by ultra-precise manufacturing down to the micron level. From mirrors on satellites to solar thin film printer heads and windows on lunar dwellings, ultra-precise manufacturing is required.

Precision Manufacturing



Our clients are in the vanguard of sustainable technology investment and commercialisation.


We advise start-ups that need to raise capital and ‘grown-ups’ that want to invest capital. Independent investment companies, corporate VCs and government innovation agencies seek our support in sourcing investments and co-investors.


All are united in seeking out sustainable growth.

Thought Leadership

Unless you are in stealth mode, direct communications with investors can be complemented by communication via media, reports and events, digital and ‘real’.


Working alongside our clients’ media advisors, Leif Capital interviews client senior management and secures the interviews’ publication in investor media. Our CEO Tom Whitehouse also produces informative articles on our current projects and uploads them to our blog.
