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.
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.
Vest applied to YC in late 2014 and joined the Winter 2015 batch. The consumer framing — a website offering personalized protected investments to anyone — was the pitch. The underlying financial engineering was the same regardless of which distribution channel ultimately won.

The Original Consumer Product (2015)
At YC, Vest described its product as a website offering personalized "Protected Investments" — instruments that combined "the safety of a savings account and the growth potential of equity."[1] The underlying mechanism was a FLEX Options strategy: Vest would construct a position using exchange-traded flexible options on the S&P 500 that, over a defined period (typically one year), would absorb the first 10% of market losses while allowing participation in gains up to a predetermined cap.
In plain terms: if the S&P 500 fell 8% in a year, the investor would lose nothing. If it fell 15%, the investor would lose 5% (the amount beyond the 10% buffer). If it rose 12%, the investor would gain up to whatever cap had been set — say, 10%. The product was not a savings account, but it was designed to feel safer than a direct equity investment for risk-averse retail investors.
The consumer product's technical architecture is not well-documented in public sources. The YC description implies a web-based platform where users could select protection parameters and invest directly. No product screenshots, user counts, or revenue figures from this period have been disclosed, which is itself a signal: the consumer product may have been in beta or pre-launch at the time of the CBOE acquisition.
The Core Financial Innovation: FLEX Options and Target Outcome Investing
The genuine intellectual contribution was the application of FLEX Options — a class of exchange-traded options with customizable terms — to create registered investment products with defined outcome profiles. Prior to Vest's work, structured products with downside buffers existed but were sold as bank notes (unregistered, illiquid, and opaque) or as bespoke over-the-counter derivatives accessible only to institutional and high-net-worth clients.
Vest's insight was that the same economic exposure could be replicated using listed FLEX Options within a registered '40 Act fund structure — making the product liquid, transparent, and accessible to any investor through a standard brokerage account. The patent application filed in October 2012 formalized this concept as "Target Outcome Investments."[7]
The Institutional Product Suite (2016–2025)
After the CBOE acquisition, Vest built out a full product family:
What distinguished Vest from alternatives was the combination of exchange-traded (therefore liquid and transparent) instruments, registered fund structures (therefore accessible to retail through advisors), and a systematic, rules-based approach to outcome definition. The product was not a black box — investors knew exactly what buffer and cap they were getting before they invested.
At YC, Vest's stated target was retail investors — specifically, risk-averse savers who wanted equity-market participation without full downside exposure. The implicit customer was someone who had money in a savings account or money market fund earning near-zero returns and was unwilling to invest in equities due to fear of loss.
After the CBOE acquisition, the target customer shifted to registered investment advisors (RIAs) and financial planners who manage portfolios for retail clients. The product remained accessible to retail investors, but the sales motion became B2B: Vest would distribute through advisors and fund platforms rather than directly to end investors. First Trust's 44.3% ownership stake (49.3% voting) in Cboe Vest Group as of early 2020 reflects this distribution logic — First Trust is one of the largest ETF distributors in the U.S., with deep relationships with the advisor community.[15]
The defined outcome investing market did not exist as a named category before Vest created it. The addressable market can be framed several ways:
The competitive landscape for Vest's original consumer product was structurally unfavorable along the dimension that mattered most: distribution reach. Direct-to-consumer fintech for complex financial products requires either massive marketing spend to acquire customers or a trusted brand that reduces the friction of explaining a novel instrument. Vest had neither in 2015. Its $1.47M in total pre-CBOE funding[11] was insufficient to build consumer distribution for a product that required significant investor education.
The institutional competitive landscape was more favorable. When Vest launched BUIGX in September 2016, no other firm had created a buffer product in a '40 Act mutual fund structure. The first-mover advantage in a registered fund category is meaningful: fund platforms, advisor due diligence processes, and distribution agreements all favor incumbents once established.
By 2019, when Vest expanded into ETFs, competitors had begun to emerge. Innovator ETFs launched its own buffer ETF lineup in 2018, and First Trust (already a Vest partner) launched its own Target Outcome ETF series. The competitive dynamic shifted from "no competition" to "category expansion" — multiple players growing a market that Vest had created, rather than zero-sum competition for existing assets.
The structural advantage Vest maintained was its patent position on Target Outcome Investments and its CBOE relationship, which provided both credibility with institutional buyers and access to CBOE's derivatives expertise. Competing on product depth (the sophistication of the FLEX Options engineering) rather than distribution reach was a more defensible position than the consumer product would have been.
Consumer Phase (2015)
The consumer product's revenue model was never publicly disclosed. Inferring from the product description — personalized protected investments delivered via a website — the most likely model was a management fee on assets (similar to a robo-advisor) or a spread embedded in the options pricing. No revenue figures from this period have been disclosed, which is consistent with the product being pre-revenue or in early beta at the time of the CBOE acquisition.
Institutional Phase (2016–present)
Post-acquisition, Vest operates as an asset manager charging management fees on AUM. Standard management fees for defined outcome ETFs and mutual funds in this category range from 0.74% to 0.99% annually. Applying a conservative 0.75% blended fee to the $46.6B AUM figure reported in July 2025[2] implies gross revenue in the range of $350M annually — though this is an inference, not a disclosed figure, and actual fee rates and revenue sharing arrangements with distribution partners are not public.
The unit economics of the institutional model are structurally superior to the consumer model. With approximately 35 employees[18] managing $50B+ in assets, Vest operates at an AUM-per-employee ratio of roughly $1.4B — a level of capital efficiency that would have been impossible in a direct-to-consumer model requiring customer acquisition, support, and compliance infrastructure at scale.
Pre-CBOE (2012–2016)
No user counts, revenue figures, or consumer traction metrics from the YC period have been disclosed. The $1.47M in total funding across two rounds[11] is the only quantitative signal from this period. The absence of any disclosed consumer metrics — in a period when fintech companies routinely publicized user growth — suggests the consumer product had not achieved meaningful scale before the CBOE acquisition.
Post-CBOE Institutional Growth
The institutional traction data is more robust:
The acceleration from $370M to $3.4B between early 2020 and mid-2021 coincides with the COVID-19 market volatility of March 2020 and the subsequent bull market — a period when investor demand for downside protection spiked. The 13x growth from $3.4B in mid-2021 to $46.6B by mid-2025 reflects both organic AUM growth and the broader adoption of defined outcome ETFs as a mainstream advisor allocation tool.
Karan Sood framed the $50B milestone in July 2025 as a category signal rather than a company milestone: "This isn't just about Vest's growth, $50 billion demonstrates that the financial advice and planning industry has shifted."[19]
This report departs from the standard post-mortem format because Vest did not fail — it pivoted. The analysis below examines why the original consumer product did not survive, why the pivot succeeded, and what structural forces made the institutional path dramatically more viable than the consumer path.
The consumer product's core problem was not the financial engineering — that was genuinely novel and valuable. The problem was that distributing complex, novel financial instruments directly to retail investors requires either a trusted brand (which takes years and capital to build) or a regulatory and compliance infrastructure that is expensive to maintain at small scale.
Vest raised approximately $1.47M in total pre-CBOE funding.[11] For context, Betterment — a far simpler robo-advisor product — raised $3M in its Series A alone in 2010 and still required years and tens of millions of dollars to reach meaningful AUM. A product as complex as a FLEX Options-based buffer strategy, requiring investor education about buffers, caps, and outcome periods, would have required substantially more capital to acquire and retain customers than Vest had available.
The $1.47M figure also implies the consumer product was likely pre-revenue or in very early beta at the time of the CBOE acquisition. No consumer traction metrics were ever disclosed — not user counts, not AUM on the consumer platform, not conversion rates. In the fintech environment of 2015–2016, companies with meaningful consumer traction publicized it. The silence is informative.
The attempted remedy — YC participation and VC fundraising — did not generate sufficient capital to test the consumer distribution thesis at scale. The CBOE acquisition, announced just months after YC Demo Day, effectively ended the consumer experiment before it could be validated or falsified.
There is a deeper structural explanation for why the consumer product was unlikely to succeed regardless of funding. Protected investments with defined outcome periods require investors to understand and commit to a specific time horizon — typically one year. Retail investors who are unsophisticated enough to need downside protection are also typically the investors least likely to understand outcome periods, caps, and the mechanics of FLEX Options resets.
The advisor channel solves this problem. A registered investment advisor can explain the product, match it to a client's risk profile, and manage the annual reset process. The product's complexity is an asset in the advisor channel (it justifies the advisor's fee) and a liability in the direct-to-consumer channel (it creates friction and abandonment).
Vest's parallel development of a "technology solutions line of business" starting in 2014 — before YC — suggests the founders may have recognized this dynamic early. Bill Kung and Daniel Roos joined specifically to build B2B technology capabilities.[9] The consumer product may have been the YC pitch, but the institutional product was already being built in parallel.
The CBOE majority investment in January 2016 is best understood as a strategic acceleration of the institutional path rather than a rescue of a failing consumer product. CBOE's interest was in the FLEX Options-based financial engineering — a product category that would drive trading volume on CBOE's exchange. The consumer product was irrelevant to that thesis; the institutional product was central to it.
The announcement venue — the Inside ETFs Conference, the premier gathering of ETF industry professionals — signals that CBOE was positioning Vest as an institutional product company from day one of the acquisition.[12] The exit of all prior VC investors (YC, Payment Ventures, First Round Capital) in the same transaction[12] completed the clean break from the consumer fintech model.
Sood's public framing of the deal as a "strategic alliance" — "CBOE is globally recognized as a leading exchange for derivative products and has a rich history of product innovation, making them the ideal strategic partner for us going forward"[20] — is the language of institutional partnership, not consumer product scaling.
The original YC pitch promised to make protected investments available to everyone. The institutional model partially fulfills this promise through a different mechanism: ETFs, which any retail investor can buy through a standard brokerage account, provide access to buffer strategies without requiring a minimum investment or a private banking relationship.
However, the direct-to-consumer personalized product vision — where an individual investor could customize their own buffer and cap parameters through a website — was not realized. The ETF model standardizes the product (a specific buffer percentage and outcome period) rather than personalizing it. The democratization is real but incomplete relative to the original vision.
This gap between the founding vision and the realized outcome is not a failure of execution — it reflects a genuine tension between product complexity and consumer accessibility that the institutional model resolves by inserting a professional intermediary (the advisor) between the product and the end investor.
The institutional pivot succeeded for a specific structural reason: Vest was first. The BUIGX mutual fund launched in September 2016 was the first buffer product in a '40 Act structure.[13] In the registered fund industry, being first matters: fund platforms add the fund to their approved lists, advisors build familiarity with the product, and the fund accumulates a track record that competitors cannot replicate.
By the time Innovator ETFs launched competing buffer ETFs in 2018, Vest had two years of institutional relationships, a track record, and a patent position. The category it created was large enough for multiple players, but Vest's position as the originator — "the creator of the first Buffer Fund and the pioneer of defined outcome investing"[21] — provided durable brand equity in the advisor community.
The YC consumer framing was a distribution hypothesis, not a product hypothesis. Vest's core innovation — Target Outcome Investments using FLEX Options — was genuine and valuable regardless of distribution channel. The YC pitch packaged it as a consumer product, but the underlying financial engineering was channel-agnostic. When the consumer distribution hypothesis failed to attract sufficient capital to test at scale, the product survived by finding a more structurally appropriate channel. Founders with genuinely novel technology should distinguish between the innovation and the distribution model — the former can outlast the latter.
Complexity is a liability in direct-to-consumer fintech and an asset in advisor-intermediated distribution. Vest's buffer products require investors to understand outcome periods, caps, and annual resets — concepts that create friction in a self-directed consumer context but justify advisor fees in a B2B context. The $1.47M raised before CBOE was insufficient to build the consumer education infrastructure needed to overcome this friction. The advisor channel solved the education problem by design: advisors explain the product, and their clients trust the explanation. Products with inherent complexity should map their distribution model to the sophistication of the intermediary, not the end investor.
Strategic acquirers can provide distribution that VC cannot. First Round Capital and YC could provide capital and network effects for consumer fintech, but neither could provide the institutional distribution relationships that CBOE and First Trust brought. CBOE's credibility with derivatives professionals and First Trust's relationships with the RIA community were worth more to Vest's institutional product than any amount of consumer marketing spend. For fintech companies building products that require institutional trust or regulatory credibility, strategic investors with distribution relationships may be more valuable than financial investors with capital alone.
First-mover advantage in registered fund categories is durable. Vest launched BUIGX in September 2016 with no direct competitors in the '40 Act buffer fund space. By the time competitors arrived in 2018–2019, Vest had established fund platform relationships, advisor familiarity, and a track record. The $370M AUM in February 2020 grew to $46.6B by mid-2025 — a 126x increase in five years — in part because the category Vest created expanded faster than competitors could replicate the originator's institutional relationships. In regulated financial product categories, the cost of replicating a first-mover's distribution relationships is high enough to sustain competitive advantage for years.
The absence of disclosed consumer metrics is itself a data point. Vest never disclosed user counts, consumer AUM, or revenue from its direct-to-consumer product. In the 2015–2016 fintech environment, companies with meaningful consumer traction publicized it aggressively. The silence suggests the consumer product had not achieved scale before the CBOE acquisition — which means the pivot was not a sacrifice of proven consumer traction but a redirection of pre-revenue technology toward a more viable channel. Investors evaluating early-stage fintech companies should treat the absence of traction disclosure as a signal about the state of the consumer hypothesis, not just a gap in reporting.
