In a rare move for a crypto down market, two of the most prestigious venture capital firms — **Index Ventures** and **Union Square Ventures** — have co-led a $75 million Series B round for **Fomo**, a crypto trading app named after the acronym for "fear of missing out." The investment values the startup at **$550 million**, signaling renewed confidence in user-friendly blockchain trading platforms. Other notable backers include Zynga cofounder Mark Pincus, Discord CEO Humam Sakhnini, and Eventbrite cofounder Kevin Hartz.

Key Insights

$75M Series B: led by Index Ventures, with participation from Union Square Ventures, valuing Fomo at **$550 million**.

Founded by former dYdX employees Paul Erlanger, Se Yong Park, and Prashan Dharmasena, who experienced firsthand how difficult onchain trading can be.

Fomo aims to onboard users in under 30 seconds, regardless of crypto familiarity, with a non-custodial model and a social feed.

The app already lists more assets than Coinbase, is available globally, and is onboarding ~3,500 new users per day with just 17 employees.

Why this matters:: During a crypto downturn, major non-crypto-native VCs like Index (known for Figma, Scale AI) are betting big on consumer blockchain — indicating a market shift toward simplified, socially-driven trading platforms.

In-Depth Analysis

The Challenge: Onchain Trading is "Impossible"

The cofounders of Fomo built the platform after witnessing the pain points of digital asset trading at dYdX. Thousands of cryptocurrencies, countless blockchains, arcane swap fees, and overly complex onboarding processes create a high barrier to entry. As Erlanger put it: "Onchain trading is just impossible."

Fomo's Solution: Simplicity + Social

Fomo's approach is twofold. First, it strips down the experience so that any user can fund an account and buy a token within 30 seconds. Second, it layers on a social dimension — a leaderboard of top traders, a feed of recent trades, and the ability to share trading history on social media. The company's name is officially short for "fearless" of missing out.

Not Just a Crypto App

The founders envision Fomo as a broader gateway to finance. As stocks, derivatives, and other assets migrate to the blockchain, Fomo plans to list them all. In June 2026, it already added perpetuals (futures contracts with no expiration). "The goal is for it not to be seen as a crypto app," said Erlanger.

Competitive Landscape

Fomo competes with giants like Coinbase and Robinhood, but its non-custodial model — where the platform does not handle customer funds — provides regulatory flexibility. The startup remains compliant while operating globally. With fresh capital, Fomo plans to hire more engineers and potentially acquire smaller companies.

Historical Context

Index Ventures previously backed Bridge, a stablecoin startup acquired by Stripe for $1.1 billion in 2025. Union Square Ventures has investments in Polygon and Matter Labs. This track record demonstrates that despite the bearish sentiment in crypto, these firms see a fundamental market shift in consumer blockchain trading.
