It didn't start with a business plan. It started with a layoff.
Msizi had always wanted to build something of his own, but went the conventional route first: a software engineering job straight out of varsity. It didn't stay conventional for long. Barely out of school, he was carrying responsibilities closer to a senior engineer's than a junior's, a steep and fast education.
Four-plus years of real, hands-on engineering behind me and, honestly, nothing left to lose.
When that job ended, so did the reason to wait. He started onemanstack, and "one man" is still close to literal: every layer of the stack, handled by one person. That was never a philosophy. It is where things stand, with a plan to grow into a team as the work grows.
His sister Siphokazi helps along the way, part-time, with marketing and the occasional client meeting. Family is where you find the people who believe in the idea before there is anything to show for it. Everything else, the engineering, the operations and the client work, runs through Msizi.
