We know one size does not fit all. Your business is as unique as you are. That is why we have varied solutions to address your unique needs.

Starting and growing a business to a significant level takes a lot of effort. It requires resilience, patience, a good sense of humour, and real grit. Our goal is to help businesses grow. Although we cannot guarantee that it will always be easy, we can assure you that it will be worth it. We understand that one-size-fits-all programs are not effective. Therefore, we have created service lines that cater to various needs as part of our growth engineering process.


We are nothing without our partners, and over the years we have worked with many organisations and intend to continue to do so. Co-owned by Knife Capital and Thinkroom Limited, Grindstone believes that partnerships are of utmost importance in our quest to help businesses grow. Below are some of our partners we have worked with over the decade, and we continue to find partners who have entrepreneurship growth as a core principle to their organisations.

Special mention goes to The SA SME Fund, who without their support, Grindstone and Grindstone Ventures would not have had the seeding and growth we have experienced over the last number of years as we use acceleration as a way to help enable growing venture capital as an asset class in the countries we operate in.


We have seen many successes from businesses that have completed our programmes, some of which are shown below. Your business could be one of them.

We have been assisting early-stage innovative startups through Grindstone since 2013, and we are proud to have helped hundreds of individuals scale their businesses, become fundable, exit-ready, or exit successfully. Our support has extended to entrepreneurs from various backgrounds, including students, CFOs, and medical specialists, who all needed Grindstone to scale their business to the next level. Hear what some of our alumni have to say.

"I found the Grindstone program to be incredibly valuable for both my business and myself. The program provided access to experts in various business areas, which proved to be priceless. As a small business, the support we received was invaluable. Building relationships with fellow founders and companies was one of the best aspects of the program. Additionally, the extended network we gained access to was exceptional. I am very selective about which accelerators and groups we join, but Grindstone has been one of the best choices for us."
