A free, no-equity accelerator for 20 companies a year
A structured entrepreneurship development programme co-owned by Knife Capital and Thinkroom, helping high-growth innovation-driven companies become more sustainable and fundable.
Use when
You are a high-growth South African company preparing to raise and want funding-readiness work without paying fees or giving up equity.
Skip when
You want a cash investment directly from the programme - this is readiness support, and the capital comes separately.
