The support Calculus has provided to Mologic in 2015 and 2018 has been transformational. Without this, the transition into a sustainable social enterprise would not have been possible and would have seriously limited capacity to take on the diversity of disease targets

The EIS Association (EISA) is the official trade body for the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) industry. EISA is a highly effective not-for-profit organisation that exists to aid the provision of capital to UK small and medium-sized enterprises (SMEs) through these two schemes.

EISA works closely with HM Treasury, HM Revenue and Customs, government ministers, MPs and the FCA to enhance EISs and SEISs and promote the benefits of using them to investors, companies and their respective advisers. EISA collaborates with other trade bodies that support investment into SMEs, including the British Venture Capital Association (BVCA), the Association of Investment Companies (AIC), the Institute of Chartered Accountants in England and Wales (ICAEW) and the UK Business Angels Association (UKBAA). The EISA Director General sits on the BVCA Venture Capital Working Group, which aims to present a unified voice from all sections of the SME and venture finance industries to the UK government and the EU.

EISA’s membership is drawn from all areas of the EIS/SEIS industry and includes EIS/SEIS fund managers, lawyers, accountants, tax advisers, corporate financiers, IFAs and wealth managers throughout the UK.
