African start-ups more than doubled the amount of debt they raised last year, a surge that may continue as an economic slowdown makes equity funding more expensive and unsustainable over the long term.

Companies on the continent raised US$1.55-billion (R26.8-billion) in 71 debt deals in 2022, suggesting it’s become a solid alternative source of capital for African technology start-ups, venture capital firm Partech Partners said in a report.

The surge helped the African technology sector become “one of the very few, if not the only, VC markets to boast net growth funding in 2022”, the Paris-based company said.

VC funding grew 8% to $6.5-billion in Africa, whereas globally it fell 35% last year, according to the firm’s annual survey of start-ups that have most of their operations in, or get the bulk of their revenue from the continent. Market intelligence company Briter Bridges’ data showed African start-ups raised a record $5.3-billion last year.

Fears of a global recession and slowing sales have led to a sell-off in the world’s largest technology companies, prompting some such as Google and to cut jobs. The slump has made private equity and venture capital firms reluctant to invest, increasing the cost of equity and forcing start-ups to look for alternative funding.

The number of active debt investors on the continent is growing 2.5 times year on year, with a good mix of local debt institutions, international lenders and development finance institutions, the report said.

Most of last year’s debt financing went into fintech and clean technology start-ups such as Moove.Africa and D.Light, the study found.
