Solo founder's micro1 passes $1B run rate with only ~180 employees

micro1, founded solo by Ali Ansari, has passed a $1B annual run rate and is profitable with a core team of just 180 people across 14+ countries, selling model-training data services to AI labs.
Three years ago the company lost 60% of revenue overnight when a customer feared competition and nearly went bankrupt; Ansari doubled down on the same market instead. His 8 operating principles include decisions that forgo hundreds of millions in short-term revenue, like refusing work from adversarial nations.
The same newsletter notes Polsia (Bencera) nearing a $25M run rate, SFP founder Manan pushing the Pareto frontier in multilingual speech recognition, and the launch of Solo Angels for early-stage investing in solo-founded companies.
