RMB Ventures Exits Afrikelp as SAS Group Takes Majority Stake

RMB Ventures has exited Afrikelp, and SAS Group, a portfolio company of Stirling Square Capital Partners, has taken a majority stake in the business. Africa Private Equity News reported the ownership change, which marks the end of the South African private equity firm's hold on the seaweed-based products company.

The deal transfers control of Afrikelp from a regional private equity investor to a European-backed consolidator. Stirling Square Capital Partners, the London-based firm that owns SAS Group, now steers the company's next chapter. That shift matters for how Afrikelp will be run, funded and grown from here.

Who is buying whom?

SAS Group is the acquirer. It operates under Stirling Square Capital Partners, a mid-market private equity house that takes controlling positions in companies with international reach. Afrikelp is the target. The company processes seaweed into products used in agriculture, supplying farmers with inputs derived from kelp harvested off the African coast.

The transaction gives SAS Group majority ownership. RMB Ventures, the private equity arm of Rand Merchant Bank, sells its position and steps away from the asset entirely. Africa Private Equity News, which first reported the story, framed the deal as a full exit rather than a partial sell-down.

What does the exit signal?

A clean exit tells the market several things. First, RMB Ventures reached the end of its holding period and found a buyer willing to pay for control. Second, the buyer saw value in Afrikelp that a strategic owner, rather than a financial one, could unlock. Stirling Square typically builds groups through add-on acquisitions, so Afrikelp may not remain a standalone asset for long.

For RMB Ventures, the sale closes a chapter in a portfolio built around South African mid-market companies. For SAS Group, the purchase adds a products business with a raw material source rooted in African coastal waters, a supply angle that European processors often lack.

Private equity exits in Africa's mid-market remain relatively scarce compared with larger buyouts that attract pension funds and development finance institutions. A control sale to an international strategic group is one of the cleaner paths available to sellers in this segment, and RMB Ventures appears to have taken it.

Why does seaweed matter to the buyer?

Afrikelp works with kelp, a raw material used in agricultural inputs such as plant-growth stimulants and soil conditioners. Seaweed-derived products sit in a niche that has grown steadily as farmers search for biological alternatives to synthetic inputs. Companies with secure access to kelp harvesting hold a structural advantage, because the raw material cannot be manufactured, only harvested from the sea.

Afrikelp's location gives it that access. The African coastline supplies kelp in volumes that support commercial processing. SAS Group, with Stirling Square's capital behind it, can now integrate that supply into a broader platform and push distribution into markets RMB Ventures was less positioned to reach.

The logic follows a familiar private equity playbook: buy a producer with a hard-to-replicate input, bolt it onto an existing group, and expand sales through the group's channels. Whether SAS Group executes that plan will show in its next portfolio moves.

What happens next?

SAS Group now holds majority control and will direct Afrikelp's operations, investment and expansion. Stirling Square's involvement suggests the group will look for growth beyond Afrikelp's home market, consistent with the firm's pattern of building international businesses from controlling stakes. Africa Private Equity News reported no further deal terms, so the price and structure of the transaction remain undisclosed.

For observers of African private equity, the deal adds one more data point to a thin exit record. Every completed sale in this market segment strengthens the case that mid-market African assets can attract international strategic buyers, not just regional financial sponsors. The next test is whether Afrikelp's new owner invests to grow the business or simply folds it into a wider portfolio and harvests the supply chain.
