WithAI

WithAI provides a sophisticated artificial intelligence platform tailored for the institutional investment sector, targeting clients such as hedge funds and asset managers. The company was founded in 2026 by Benjamin Finch and Ian McInnis and is part of the Y Combinator Spring 2026 cohort. The founders converged on the business idea from different paths; McInnis was an investor at Bridgewater Associates exploring the use of LLMs in investing, while Finch was the founding researcher at AI lab Sentient Labs, focusing on enterprise AI solutions. They had previously co-founded a technology investment group during their time at Princeton University. The firm's core offering is 'Multiplier,' a secure platform described as a custom command center for investors. It is designed to address the inefficiency of manual research and data management by integrating a fund's specific processes, data sources, and tools into a unified AI-driven system. The platform connects with a wide array of financial data and software providers including Bloomberg, FactSet, and S&P Global, allowing the AI agents to automate stock research and portfolio tracking. WithAI's business model is centered on a consultative, B2B approach, deploying the Multiplier platform directly onto client servers to ensure data security and sovereignty. This strategy enables independent asset managers to leverage advanced AI capabilities that can compete with the large-scale, in-house projects of major financial institutions.
