Greg Isenberg notes Postiz — a tool covering posting, email, payments, phone numbers and browsing for agents — quickly reached $275K MRR. alvelda argues the fastest-growing software may be the tools agents use, not the agents: "build something agents call a thousand times a day."
Other vertical businesses he sees taking off:
- Data brokering: selling rare/expert knowledge to labs and companies training their own agents
- Hosting for agents: renting always-on machines so people can run agents 24/7
- Compute reselling: buying GPU capacity in bulk and renting it out to smaller teams
- Vertical harnesses: agents built for one industry and one workflow
