About

Mapleton Capital Management provides discretionary portfolio management to high‑net‑worth individuals, family offices, trusts and a small number of separately managed accounts, and serves as the general partner and investment adviser to three privately‑offered pooled investment funds. The firm reports roughly $87.8 million in discretionary assets under management, a small overall client base, and a limited advisory staff supporting those mandates.

Its investment process is grounded in fundamental research aimed at identifying early inflection points and often uses an active, sometimes aggressive trading approach that can include short positions, options and the opportunistic use of leverage and cash. Mapleton manages SMAs with a similar style but operates its pooled vehicles under a performance‑based allocation framework and places fund trades in coordinated block executions through prime brokers.

Mapleton’s structure and relationships are notable: it operates from six offices, shares trading and research resources with an affiliated registered adviser, and sponsors and advises private pooled funds — a combination that is less common among similar supported firms. The firm discloses several related conflicts (including the priority of fund trades over SMAs and the use of third‑party service providers who receive fees from the funds) and describes mitigation practices such as coordinated block trading and periodic reviews of related‑party arrangements.
