Why Optomise?

Many taxpayers are reluctant to enter into Section 12J transactions as they are uncertain how the South African Revenue Service (SARS) will view, and ultimately tax, the income derived from these transactions. Optomise has obtained unique private binding rulings relating to S12J investment compliance. These rulings have provided us with clarity, consistency and certainty about the interpretation and application of the relevant tax laws.

Our fund is licensed by the Financial Sector Conduct Authority (FSCA) and we utilise an FSCA-approved compliance officer.

What differentiates Optomise from other traditional funds is that we have reversed the venture capital funding model. Prior to raising capital, Optomise identifies qualifying S12J projects and then go to the market to raise the funding. This results in an immediate deployment of capital into projects and thus eliminates “lazy money” sitting in the fund.



Gadi Cohen

Managing Director

Gadi founded Optomise in 2015, with the aim of building a unique investment platform focused solely on compliance. He identified the need for a dynamic S12J fund that could offer individual investors the opportunity to invest in new projects and businesses while being able to benefit from the S12J tax incentive. Having developed unique intellectual property, and armed with binding private rulings directly from the South African Revenue Service (SARS), Gadi has facilitated more than 20 venture capital transactions and raised over R500 million in equity finance.

A business development expert, Gadi is part of Optomise’s investment, strategic and product development committees.

Gadi completed his Bachelor of Business Science (Hons) in finance at UCT in 2010 and went on to complete his Post Graduate Diploma in Accounting (PGDA) with honours in accounting in 2011 at UCT. He qualified as a chartered accountant (CA)SA in 2014.
