Summary
SigTech, the agentic artificial intelligence platform spun out of hedge fund Brevan Howard in 2019, appears to have shut down without public announcement. The platform's website is no longer functioning, and a Companies House filing indicates that founder and CEO Bin Ren was terminated as an employee in late December 2025. Neither Brevan Howard nor Ren responded to requests for comment regarding the closure.
The shutdown is particularly notable given SigTech's recent market debut. The platform launched its MAGIC product—multi-agent generative investment copilots—at Bloomberg Invest in 2025, positioning the tool as a solution for domain-specific investment challenges including macro research, equities fundamental analysis, and commercial loan underwriting. MAGIC relied on autonomous AI agents powered by large language models to accomplish tasks without direct human intervention, representing a significant commitment to agentic AI technology in the investment management sector.
Bin Ren, who established SigTech after founding Elwood Technologies in 2018 to manage cryptocurrency investments for Brevan Howard, is listed on his LinkedIn profile as a former chief investment officer of Brevan Howard's Systematic Investments Group. As of 2021, SigTech employed approximately 50 people, though the current status and placement of those employees following the apparent shutdown remains unknown.
The disappearance of SigTech reflects broader instability at Brevan Howard. The firm is simultaneously managing the spinout of Tekmerion Capital Management—which joined the organization less than two years prior—and has experienced multiple departures among senior technologists. The convergence of these organizational changes suggests potential strategic recalibration at the investment firm, though specific details remain undisclosed.
