## About

Survey Sampling International (SSI) is a market research services company, not a family office or investment firm. Founded by John Marin and others in the 1970s, SSI pioneered the provision of survey samples for opinion polling and consumer research. The company's core business involved maintaining panels of respondents and delivering targeted sample groups to clients for market studies, academic research, and political polling. SSI was acquired by the private equity firm Apollo Global Management in 2017 and subsequently merged with Research Now to form Dynata, a global leader in first-party data. As of the firm's public record, there is no disclosed investment portfolio, AUM, or family office structure. The entity operates solely as a data and sample provider, with no published investment strategy or deployment activity. No additional offices, professionals list, or wealth origin are documented. The absence of investment-related data underscores that SSI is not structured as a capital allocator or wealth management vehicle.
