In other news, Jiji, a Nigerian e-commerce marketplace, has shared its playbook for gaining market dominance. Despite launching two years behind e-commerce behemoths like Jumia and Konga, Jiji has managed to surpass its competitors, including Naspers-owned OLX, which it acquired in 2019. According to Jiji's CEO and co-founder Anton Volianskyi, the company's success can be attributed to its rigorous ad moderation, anti-scam system, and verified badges for sellers.

In an interview with TechCabal, Volianskyi discussed how Jiji scaled to success through acquisitions and cost-effective marketing. The company's efforts to reduce fraud and improve user experience have paid off, with Jiji now boasting over 6 million listings and at least 21 million users monthly.

In a separate development, Kenya has cancelled its $2.6 billion Adani deals following a US indictment of Gautam Adani, chairman of the Adani group, on bribery charges. The Kenyan government had faced opposition to the deals, which included a 30-year concession to manage Nairobi's JKIA airport, citing concerns over job losses and lack of value for money to taxpayers.

The cancellation of the deals leaves the Kenyan government with a significant budget deficit to fill. The indictment has also wiped nearly $30 billion off Adani Group's market value and removed $15 million from Adani's personal wealth.

Meanwhile, a report by TLP Advisory, a Nigerian venture law firm, has sparked debate over the state of Nigeria's startup ecosystem. The report found that 49% of Nigerian startups make less than ₦10 million ($6,000) in annual revenue, with two-thirds of these startups founded between 2019-2023. While some have questioned the report's methodology, others argue that sustainable profitability, even with lower yields, can be more valuable than high-revenue models with excessive spending.

The report also highlighted the importance of partnerships and mergers and acquisitions (M&As) in Nigeria's startup market, citing examples such as OmniRetail's acquisition of Traction Apps. With more partnerships, the country's tech ecosystem can unlock more growth opportunities.
