Firm profile

FINTRX

Overview

M4a3 LLC operates as a private equity–focused advisory and fund manager that combines portfolio management for individuals, pooled vehicles and institutional clients. The firm charges a mix of percentage-of-AUM and performance-based fees and is structured as a limited liability company owned by an individual. M4a3 LLC identifies as a private equity fund manager and allocates capital primarily to private-market strategies while also managing liquid holdings and mutual funds for clients who need broader exposure or liquidity. The firm is not positioned as an ESG investor, does not market itself as a multi-state adviser, and does not act as a pension consultant or capital allocator in the traditional sense. It is registered with the SEC (registered in 2025) and runs both discretionary and non‑discretionary mandates, with an emphasis on active portfolio construction and concentrated private fund vehicles.
