Spaulding & Slye Investments

What Spaulding & Slye Investments does

Spaulding & Slye Investments is a privately held real estate investment firm founded in 1966 and headquartered in Washington, United States. The company operates as a wholly owned subsidiary of Jones Lang LaSalle (JLL), a global commercial real estate services firm, and positions itself as providing clients and partners with an integrated service platform. The firm is led by Chief Executive Officer Marshall H. Durston, with founder Tim Fraser continuing as managing director & founder, Chief Operating Officer Brooks Bossle, and Senior Vice President Arthur C. Frye. The 11-50 employee headcount indicates a boutique-scale operation, and the Washington, D.C. base anchors it in a major U.S. capital market and federal real estate corridor.

The firm's business model is not disclosed in available source material — no pricing, fee structure, fund vehicles, AUM, customer segments, or revenue mechanics are documented. The phrase 'integrated service platform' is the only self-description, and the website (ssinvests.com) returned only a loading/verification page at the time of data collection, indicating a substantial information gap. As a JLL subsidiary, the firm is plausibly embedded within JLL's Capital Markets, Investments, or Asset Management segments, but no parent-company disclosure confirms the specific operating role.

Evidence on technology, product depth, distribution, partnerships, customers, and competitive positioning is effectively absent. The available data permits a high-level description of the firm's legal/operational identity, ownership, leadership, and scale, but does not support granular claims about the underlying business. Any deeper assessment of the firm's investment performance, product suite, or strategic direction would require primary data collection from the company, JLL parent disclosures, or third-party sources such as PREQIN or Form ADV filings.
