§ Private Profile · San Francisco, CA, USA
Social search engine indexing over a billion social profiles for users, marketers, and recruiters, focused on cross-platform people search.
Based in San Francisco, California, Ark developed a cross-platform social search engine designed to organize and index public profile information across multiple networks. The platform indexed over one billion social network profiles, allowing users to filter searches across platforms like Facebook and LinkedIn by location, employer, and interests. Operating with a team of 11 employees, the consumer internet company provided specialized search tools utilized by general users, marketers, and recruiters. The venture-backed startup raised approximately $4.2 million in seed funding from prominent lead investors including Y Combinator and Andreessen Horowitz. The technology was ultimately acquired by Yahoo in 2014, leading to the integration of its search capabilities into the acquirer's broader product ecosystem and the closure of the original service. Ark was founded in 2012 by Patrick Riley, Youssef Ahres, Jonas Templestein, and Yiming Liu.
Ark has raised $4.3M across 3 funding rounds.

Ark is a pioneering people search engine that leverages multiple social graphs to surface relevant information about individuals across digital platforms. Its mission is to make social information more accessible, organized, and actionable by aggregating data from diverse networks using a query language inspired by Facebook’s Graph API. Ark serves users seeking to discover, connect with, or research people in a privacy-conscious and efficient manner, solving the challenge of fragmented social data across platforms. The company has gained traction as a niche player in the social search space, carving out a unique position between giants like Facebook and Google by focusing on cross-platform identity and relationship mapping.
Founded in the early 2010s, Ark emerged from a recognition that social data was becoming increasingly siloed, making it difficult for users to find people or understand their digital footprints across networks. The founding team, composed of data scientists and engineers with backgrounds in social media analytics and search technology, developed Ark’s proprietary querying engine to unify disparate social signals. Early traction came from developers and marketers seeking better tools for audience research and outreach, and Ark quickly established itself as a go-to platform for social search APIs and identity resolution.

Ark is riding the wave of growing demand for identity resolution and social data aggregation, fueled by trends in digital marketing, talent acquisition, and cybersecurity. As social media continues to fragment across platforms, the need for tools that can unify and make sense of this data is more pressing than ever. Ark’s timing is ideal, as businesses and individuals alike seek better ways to navigate the digital social landscape. The company is influencing the ecosystem by setting new standards for privacy-conscious social search and enabling developers to build more intelligent, people-centric applications.

Ark is poised to become a foundational layer in the social data infrastructure, much like search engines are for web content. As privacy regulations tighten and users demand more control over their digital identities, Ark’s focus on ethical data practices will be a key advantage. The company is likely to expand its API offerings, deepen integrations with enterprise platforms, and explore new use cases in areas like fraud detection and community building. Ark’s journey reflects a broader shift toward organized, accessible, and responsible social information—making it a critical player in the evolving digital ecosystem.
