Fello is a profitable, hyper-growth, VC-backed B2B SaaS startup building the AI operating system for modern GTM teams.
We are not adding AI as a feature. We are rebuilding how marketing, sales, and operations work from the ground up using autonomous agents, LLM-native workflows, and real-time data systems. Our AI agents research accounts, enrich data, make decisions, and execute workflows autonomously. Our goal is simple: automate as much operational and cognitive work as possible.
We move fast, ship constantly, and adopt new AI capabilities as soon as they emerge. If you want to build real AI systems that operate inside a live, revenue-generating company, this is the place.
