Stonehearth Capital Management

Founder and President Peter M. D'Angelo leads the investment committee, supported by Partner Arthur T. French. The firm uses an internal research team to select and monitor third-party fund managers and separately managed account strategists. Individual client portfolios are tailored from the approved manager roster, with principals directly involved in allocation decisions.

Stonehearth does not originate proprietary direct deals. In private markets, the firm accesses opportunities through established institutional fund managers where it has maintained relationships since the mid-2000s. Public-market equity and fixed-income exposure runs through separately managed accounts at institutional strategists, supplemented by direct indexing overlays for tax optimization. The firm's sourcing advantage is manager-access, not deal-by-deal origination.

Stonehearth operates as a registered investment advisor (RIA) structured as a multi-family office. Unlike single-family offices, the firm serves multiple unrelated client families, all of whom are taxable US investors. Unlike conventional asset managers, the firm does not offer proprietary pooled vehicles or market a branded fund to external allocators.

Stonehearth primarily constructs client portfolios through separately managed accounts on the public-markets side and fund commitments in private markets. The firm does not operate a proprietary commingled fund. Private-market exposure is accessed through third-party institutional funds, not a Stonehearth-branded vehicle, which preserves the firm's independent gatekeeping posture.

The firm's client base consists of high-net-worth families, many of whom have concentrated equity positions from operating businesses or pre-IPO holdings in New England-based technology and life sciences companies. The practice is built around families navigating a single large liquidity event or holding a dominant single-stock position that requires tax-aware diversification.
