Ironlight Group raised $21 million in a Series A round to expand infrastructure for tokenized securities, including scaling its alternative trading system (ATS) and a technology platform for issuing, distributing and trading digital securities. The privately held company said the round included institutional investors and financial services executives, led by former TD Bank President and CEO Greg Braca, alongside the Sei Development Foundation.
The capital will help expand Ironlight’s marketplace infrastructure for tokenized assets, including its Ironlight Markets ATS and settlement platform. Ironlight operates a broker-dealer and an ATS for digital and traditional securities under SEC Regulation ATS and FINRA oversight. The Austin, Texas–based firm says its platform supports tokenized securities across asset classes such as private equity, fixed income, structured products, private credit and real estate, with blockchain-based settlement intended to streamline post-trade processes for institutional investors and wealth advisers.
Sei Development Foundation participation and ecosystem context
The Sei Development Foundation, which took part in the funding round, launched in 2025 as a U.S.-based nonprofit that supports adoption of the Sei blockchain network. The New York–based organization funds developer programs, education initiatives and ecosystem partnerships. In March 2025 the foundation explored a potential acquisition of genetic testing company 23andMe following its bankruptcy filing, proposing blockchain-based user control of genetic data; the proposal did not result in a deal.
The foundation has pursued other partnerships. In February, Nasdaq-listed AIxCrypto announced a strategic technology collaboration with the Sei Development Foundation to explore AI and blockchain integrations. In the first quarter of 2026, Bhutan’s sovereign wealth fund, Druk Holding and Investments (DHI), said it would deploy and operate a validator on the Sei network in collaboration with the foundation as part of Bhutan’s digital transformation efforts.
About Sei and token metrics
Sei is a layer-1 blockchain launched in 2023 focused on infrastructure for decentralized applications and digital asset trading, and is backed by investors including Multicoin Capital, Jump and Coinbase Ventures. CoinGecko data showed SEI trading around $0.069, up roughly 11% over seven days, with a market capitalization near $465 million; the token peaked above $0.37 in mid-2025.
As tokenized securities gain traction in private markets and alternative assets, Ironlight says the new funding will accelerate development of its marketplace and settlement capabilities to support broader institutional adoption.
