Technology and venture capital deals were a major theme in Africa's private capital markets last week.Throw in a couple of retail-related transactions and you pretty much have the week's activity in a nutshell.

African Rainbow Capital has agreed to take a 20% stake in Rain, formerly known as Wireless Business Solutions until June this year. The South African LTE-Advanced fixed and mobile network provider which is owned by Multisource Group has aggressive site and base station roll out goals and the new funding will help ensure it stays on that trajectory. How much they're paying for the stake was not disclosed.

At the smaller, venture-end of the scale, Flutterwave, a payments infrastructure provider for banks and businesses in Africa, has raised over $10 million for its Series A round from a group of investors led by Greycroft Partners and Green Visor Capital. It's a young company, only founded last year, but already it's processed over 10 million transactions worth $1.2 billion. The fresh funding will be used to recruit additional team members, further develop its operational capabilities and expand further across the continent.

Traditionally MENA-focused venture capital investor Wamda Capital is making its first investment in East Africa and leading a $10.3 million debt/equity Series A round in Twiga Foods, a mobile-driven supply platform for retail outlets, kiosks and market stalls in Kenya. They join T wiga's roster of banner venture investors which include  DOB Equity, AHL  Ventures and Omidyar Network among their number. Wamda's Fadi Ghandour, who takes a seat on the company's board, shared that we should look to see more deals from them in the region, "...in which we plan on being increasingly more active."
