Colosseum (crypto accelerator)

On January 24, 2024, Matty Taylor announced the launch of Colosseum as an independent organization that would run SolanaSolanaSolana is a proof-of-stake (PoS) public blockchain designed for high throughput and low latency, with SOL as its native token; it was developed by Solana Labs and launched Mainnet Beta in March 2020. It is known for design choices such as its Proof of History clock and parallel execution, suffered several network-wide outages in its early years, and became one of the crypto industry’s focal points in events including the FTX collapse, U.S. SEC lawsuits, and the listing of Solana ETFs.Open the full entry’s hackathons, accelerate winning founders and invest in early-stage crypto startups, with the Solana Foundation ending its internally managed hackathons and handing them to Colosseum. As initially designed, Colosseum would hold two to three five-week online hackathons a year; its five-week accelerator was open only to hackathon winners, and accepted teams received a $250,000 pre-seed investment and a Demo Day pitch to investors.⁠[1]

Of the three co-founders, Matty Taylor was previously head of growth at the Solana Foundation, where he started the Solana hackathon program in 2020, and earlier worked at 0x Labs and Square; Clay Robbins was previously a principal at Slow Ventures and earlier a product and growth operator at 0x Labs and Square; and Nate Levine was a software engineer on Stripe’s crypto team and earlier led engineering teams at LendUp.⁠[1]

Colosseum stated that over the preceding three years the Solana Foundation’s hackathon program had drawn about 60,000 participants, produced about 4,000 projects and seen winners raise about $600 million in venture funding, and that 80% of venture-backed Solana startups began in the online hackathons. In an interview, Taylor noted that the foundation’s developer figures tracked only open-source developers on GitHub, saying: “Most developers building on Solana are closed source.”⁠[1][2]

From March 4 to April 8, 2024, Colosseum ran its first Solana hackathon, Renaissance, which drew more than 8,300 participants from 95 countries.⁠[3]

On June 25, 2024, Clay Robbins announced that Colosseum had raised $60 million for its first fund to keep backing founders building on Solana at the earliest stage. The fund, originally targeted at $50 million, began fundraising toward the end of 2023 and closed in June 2024; it invests only in select projects drawn from Solana hackathon winners, with a standard initial check of $250,000, and was expected to be deployed over three to four years. Robbins declined to name the limited partners, saying they included ecosystem founders and hackathon alumni.⁠[4][3]

At the time of the announcement the fund had backed 10 projects, including Ore, Urani and BlockMesh, which were to present at a Demo Day on June 27, 2024.⁠[3]

On November 12, 2024, Colosseum announced the results of the Solana Radar Hackathon, the Solana Foundation’s tenth hackathon and the second run by Colosseum. More than 10,000 participants from over 120 countries submitted 1,359 final projects; the grand champion was Reflect, a decentralized currency exchange built on hedge-backed stablecoins, which won $50,000 in USDC.⁠[5]

The Solana Breakout Hackathon, whose results were announced on July 2, 2025, was the Solana Foundation’s eleventh hackathon and the third run by Colosseum. More than 10,000 participants from over 140 countries submitted 1,412 final projects; sponsors included Pump.fun, Wormhole, MagicBlock, Render, Perena, Walrus, Metaplex and Replit. The grand champion was TapeDrive, a decentralized storage network, which won $50,000 in USDC.⁠[6]

The Solana Cypherpunk Hackathon, whose results were announced on December 13, 2025, was the Solana Foundation’s twelfth hackathon and the fourth run by Colosseum. More than 9,000 participants from over 150 countries submitted 1,576 final projects; sponsors included Phantom, Arcium, Forward Industries, Raydium, Reflect and Triton. The grand champion was Unruggable, a hardware wallet and companion app for Solana, which won $30,000 in USDC.⁠[7]

On September 3, 2026, Taylor announced that the next competition, the Crypto World’s Fair, would run online from September 14 to October 12; it was the first Colosseum competition open to builders from every blockchain ecosystem rather than Solana alone, with prize tracks organized around selected ecosystems and all submissions also eligible for a general prize pool. He said Colosseum’s accelerator and venture fund would continue to invest in Solana founders.⁠[8]

The same post stated that over about two and a half years Colosseum’s hackathons had drawn more than 60,000 builders and over 9,000 product submissions, and that roughly 85% of venture-backed Solana startups had come out of Colosseum competitions. During judging in November 2026, the website listed 11,650 builders in the Crypto World’s Fair.⁠[8][9]

As of November 2026, Colosseum described its business as three parts — hackathon, accelerator and venture fund. Its hackathons run four weeks; the twelve-week accelerator begins with two in-person weeks at its San Francisco office followed by ten remote-friendly weeks, with one-on-one mentorship and a private Demo Day for venture investors; accepted teams receive a $250,000 upfront investment, and the strongest teams may receive a further $250,000 in pre-seed funding.⁠[10]

The homepage listed more than 80,000 builders, over 9,000 products launched and 74 portfolio startups, and offered tools including cofounder matching and Copilot, a crypto product research tool for founders; featured portfolio companies included MetaDAO, Ore, Hylo, Rakurai, Torque and Credible. The about page lists the team as the three co-founders plus software engineer Max Monciardini, principal Jakub Rusiecki and operations lead Aryn Savini White.⁠[9][10]

Colosseum developed STAMP (Simple Token Agreement – Market Protected), an open-source investment contract, with the founders of MetaDAO. It gives crypto founders a path from raising private capital to launching a public token through MetaDAO, using token allocations in place of equity; private investor allocations are capped at 20% of total supply, team allocations range from 10% to 40%, and tokens unlock linearly over 24 months after the token generation event.⁠[11]
