Overview

Vest Financial Group was founded in October 2012 by Karan Sood and Jeff Chang, two former ProShares derivatives veterans based in the Washington, D.C. area. The company set out to democratize structured financial products — specifically downside-protected, equity-linked investments that investment banks had historically reserved for high-net-worth clients. Vest entered Y Combinator's Winter 2015 batch pitching a consumer-facing website that would offer "personalized Protected Investments" to ordinary savers, raising approximately $1.47M from YC, Payment Ventures, and First Round Capital before the CBOE acquisition.^[1]

The consumer product never scaled. Within months of YC Demo Day, CBOE Holdings acquired a majority stake in Vest, all prior VC investors exited, and the company pivoted from direct-to-consumer fintech to an institutional asset management model. The original democratization thesis — a website anyone could use — was replaced by an advisor-intermediated B2B distribution strategy.

The pivot proved transformative. Vest launched the first buffer fund in a '40 Act mutual fund structure in September 2016, effectively creating the defined outcome investing category. By July 2025, the firm managed $50 billion in investment products.^[2] This is not a story of failure — it is a story of a YC consumer fintech that abandoned its original distribution model, found a structurally superior channel, and built a dominant institutional franchise on the same underlying financial engineering.

Founding Story

Karan Sood and Jeff Chang met at ProShares, the Bethesda-based ETF issuer known for its leveraged and inverse funds. Both spent years working with derivatives and structured products — Sood had previously worked at Barclays Capital in New York and London, holds a master's in Decision Sciences and Operations Research from the London School of Economics, and earned his undergraduate degree in engineering from the Indian Institute of Technology Delhi.^[3] Chang is a CFA charterholder who attended the United States Naval Academy and Georgetown's McDonough School of Business before joining ProShares and FBR & Co.^[4]

Their shared insight came from watching how structured products worked inside large financial institutions. Investment banks routinely offered wealthy clients equity-linked notes with downside buffers — instruments that would, for example, protect the first 10% of losses on an S&P 500 position while still allowing participation in gains up to a cap. These products were engineered using FLEX Options, a customizable exchange-traded derivative that allowed precise specification of strike prices and expiration dates. The problem was distribution: the products required large minimum investments, were sold through private banking relationships, and carried opaque fee structures. Retail investors had no access.

Sood articulated the founding thesis directly in a 2015 interview: "After over a decade experience in this area, it became clear to me that investments with a degree of protection would have a high utility in the portfolios of all kinds of investors. However, the ability to customize such investments has been accessible to only a select few."^[5] The solution, in his framing, was technology: "Vest makes it easier and potentially cheaper to build protective investments by using technology, making it accessible to a much larger pool of investors."^[6]

Vest Financial Group was incorporated in October 2012. In the same month, the founders filed a patent application for what they called "Target Outcome Investments" — outcome-oriented investment products registered under the Investment Company Act of 1940 that use FLEX Options to define specific return profiles.^[7] In 2013, they developed the "Buffer Protect" strategy: S&P 500-linked returns with a 10% downside buffer and upside participation to a defined cap.^[8]

The company operated independently for roughly two years before seeking outside capital. In 2014, Bill Kung and Daniel Roos joined to launch a "technology solutions line of business" — a parallel B2B track alongside the consumer product.^[9] The existence of this B2B track before YC is significant: it suggests the founders were already hedging the consumer distribution thesis even as they prepared to pitch it to accelerators and investors.
