Sierra has acquired Takeoff Technologies, a startup developing long-horizon AI agents. Founded in 2025, Takeoff reached nearly $10M in annualized revenue by early July.
Takeoff Technologies, founded by former Salesforce product manager Aakash Thumaty, specializes in building AI agents capable of handling extended, multi-step tasks. The startup achieved rapid traction, approaching $10M annualized revenue within months of launch.
Sierra, which develops customer-facing AI agents, acquires Takeoff to bolster its technical capabilities in long-horizon task execution. The acquisition price remains undisclosed.
Long-horizon agents represent a growing focus in AI development—systems that can plan and execute complex workflows over extended periods rather than handling single requests. This capability addresses demand from enterprises seeking AI systems for increasingly sophisticated business processes.
Takeoff's quick path to revenue demonstrates market appetite for specialized agent technology. The acquisition reflects Sierra's strategy to consolidate talent and technology as competition intensifies in the AI agent space.
