Mako Nguyen was a software engineer in Japan who wanted her work to reach more people than a single employer would allow, so she set out to build a product of her own. The result was Robopost, a social media scheduling and automation tool aimed at the small business owners she kept watching struggle to post consistently. She gave herself a tight two-month window to ship a first version, using FastAPI on the backend and React on the frontend, and deliberately kept the scope small. It was not polished, but it solved the core problem well enough to put in front of real users and start collecting feedback.

Her first paying customers were people she already knew: small business owners who trusted her enough to pay for the product while it was still rough. By her account those early accounts mattered far more than their revenue, because they gave her the encouragement and direction she needed to keep shaping the tool. She is candid that a handful of paying users at the start felt like a major win when nothing was guaranteed.

The real growth lever, by her own telling, was Meta Ads. She nearly walked away from them early on, when the spend felt like money disappearing for little return. Her view is that most founders quit during exactly that learning phase, before the algorithm has figured out who the right customers are. She kept testing creatives, adjusting, and optimizing, and once the targeting started working the channel became the engine behind most of Robopost's growth. She frames the lesson plainly: the early returns are weak on purpose, and patience is the thing that separates the people who make paid acquisition work from the people who give up.

Alongside paid ads she treated SEO as the slower second track, publishing useful blog content and free tools so organic traffic could eventually carry more of the load and reduce her reliance on advertising. She also began experimenting with YouTube tutorials and product demos, and added AI features built on OpenAI's image and text generation so users could draft posts quickly. By the time she wrote up the first year in October 2024, she put Robopost at a self-reported $55k MRR, run almost entirely on her own.
