Why Calculus Capital?

Calculus are pioneers of the tax efficient investment industry, having launched the UK’s first approved EIS Fund in 1999. Our focus has remained consistent: building diversified portfolios of smaller, UK growth businesses and creating value for our investors through our multi-award winning funds.

Our diligent process, record of profitable exits and focus on capital appreciation distinguishes us from other EIS and VCT fund managers. The Calculus investment strategy has remained consistent for the past 10+ years, together with our structured investment process, strong risk management and very close monitoring of portfolio companies. We have been able to produce significant results for our clients via tax free dividends for our VCT investors, or tax free capital gains for our EIS investors.

We are incredibly proud of our results – our performance enables tax free dividends for our VCT and tax free distributions for our EIS Funds. Some examples of recent Exits are below – our figures do not include tax reliefs:

  • Synpromics (August 2019) Details are not publicly available but return multiple significantly exceeded target of 2x return
  • Horizon (September 2015 & August 2016) 1.82x
  • Metropolitan Safe Custody (September 2016) 1.81x
  • Scancell (April 2014) 8.2x
  • Waterfall (December 2014) 5.3x

Evidence of the Fund’s successful approach is also demonstrated by our loyal investor base, many of our clients have invested in multiple Calculus Capital EIS Funds as well as our VCT. A large number of our investors are experienced fund managers and investment professionals who have discovered us through recommendations within the industry.

We are sector diverse, our focus is to find and back great management teams working in entrepreneurial companies successfully selling real products and services. These companies will then form part of our VCT and EIS Funds.

We offer capital appreciation with managed risk:

  • Sector diversified portfolio of 6-10 companies for our EIS Fund, around 25-30 for our VCT
  • Targeting entrepreneurial companies with proven management teams
  • Target IRR of 20%
  • Typical investment size £2-5 million
  • Failure rates are typically lower and time to exit is shorter than for start-up investments
  • Typically hold investments for a period of 4-5 years on average

We benefit from privileged sources of deal flow – a substantial number of investment opportunities come from management teams that we have successfully backed in the past, other sources include our investor base and industry relationships.

Our long track record of successful exits is down to our talented investment team and the thorough and robust processes they follow.

  • We execute in depth due diligence of investment opportunities using our experienced investment team and external parties, this process normal takes 4 – 7 months
  • Our ‘hands on’ approach after investment means we constantly monitor performance and effect change when needed, we usually have a member of the team on the board
  • Our talented investment team has experience in a diverse range of sectors. The core team has been together for over 10 years and we have since attracted significant talent from top institutions
  • We always consider exit strategies before we make an investment and our detailed investment agreements are often written with this in mind

From the moment we invest in a company, a partnership is formed. We help our investee companies create value by actively supporting the business, sharing our market knowledge and connections and using our long standing experience of growing small UK companies.

We also run a series of ‘toolkit’ seminars including CEO forums and CFO workshops, where our portfolio companies can meet their peers, exchange ideas and hear from a leading industry expert. Often, the issues facing small businesses are similar regardless of sector. An upcoming forum is focused on ‘building a brand’, recent topics included ‘scaling up’ and ‘how to build a leading sales team’.

Our History

Calculus Capital was founded in 1999 by John Glencross and Susan McDonald, following careers at senior levels in leading investment banks. They saw an opportunity to create an EIS Fund which would deliver the benefits of EIS investing, whilst providing stronger risk mitigation than investing in single EIS Qualifying Companies. With the co-operation of the The Inland Revenue (now HMRC) and working within existing legislation, Calculus created the UK’s first approved EIS Fund in 1999/2000 tailored to the needs of private investors. Since then, Calculus have gone on to launch 20 EIS Funds and 5 VCT share issues.

Both the Calculus EIS Fund and Calculus VCT provide investors with the opportunity to benefit from many years of invaluable experience. The core team has been together over 10 years and our track record of excellent results has enabled us to attract top talent to this team from distinguished firms such as Deutsche Bank, Flemings, Citigroup, JP Morgan and Apollo.

We have built and retained a strong reputation as an expert investor in EIS and VCT Qualifying Companies through our multi award winning funds. The professionalism of our investment process, track record of profitable exits and focus on capital appreciation combined with strong risk management, distinguishes us from other managers.

Calculus Capital is viewed as the industry standard within the tax efficient investing world, our team is often engaged in discussions with industry and governmental representatives. Our EIS and VCT Funds embody the spirit of professional SME investing and have gained much respect and support from investors, advisers, governments and our peers.
