Earlier this year, Forbes Africa named Africa's top 20 tech startups. No Rwandan company made it to the list: maybe this will spur us into action so as to make it on the continental (and then global) playing field.

One of the criteria was that the start-up must have been around for less than 10 years and provide solutions pertinent to the continent's needs; Forbes also hand-picked these sites based on social media presence.

Here goes:

MXit: Founded by Namibian techpreneur Herman Heunis, Mxit is a mobile instant messaging (IM) utility with services including social networking, mobile voice clips, multi-media, banking access and other community based applications. Mxit subscribers can also connect to other social networks and instant messaging. It boasts 10 million users.

Sembuse: A South African mobile social network & instant messaging platform similar to Mxit.

Yola: Founded by South African internet entrepreneur VinnyLingham, Yola is a website builder and hosting service which lets you create your own site with easy-to-use drag and drop multimedia features. It hosts 6 million users.

Dropifi:A Ghanaian web messaging platform which helps bridges website owners and their visitors to better analyze and respond to incoming inquiries.

Cobi Interactive: A South African mobile software development company that provides mobile technology and strategy consulting for top African corporations; this is done through custom software design and development.

FloCash: For anyone with an email address and mobile number who wants to send and receive money across Africa easily, as well as carry out mobile phone purchases.
