About ThirdHorizon
ThirdHorizon is a Tokyo-based portfolio-company advisory and Managed IR firm. We help private-capital sponsors and management teams turn defined capability gaps into accountable workstreams.
The Firm
We work primarily with PE, growth-equity, VC and CVC sponsors—and the companies they back—when senior capability is needed without building every role internally.
Our model combines a curated network of experienced operators and specialists with ThirdHorizon-led diagnosis, team assembly, workflow management and quality control.
Managed IR remains a flagship workstream. Selected private-markets and strategic mandates remain part of the firm where local context and cross-border execution can materially improve the outcome.
Operating Model
ThirdHorizon maintains a curated network of senior professionals, but clients do not simply receive an introduction. ThirdHorizon defines the mandate, assembles the team, manages delivery and remains accountable for the engagement.
