Milestones

Mumtaz left Coinbase to co-found Helius, a developer tooling and infrastructure firm for the Solana blockchain, with Liam Vovk and Nick Pennie.

Mert Mumtaz joined Coinbase as a software engineer on the platform team, where he developed a deep interest in the Solana blockchain.

Following the collapse of FTX, Mumtaz became a key public advocate for Solana, using his technical expertise to restore confidence in the ecosystem.

Helius announced a $9.5 million Series A funding round led by Foundation Capital, with participation from Solana's co-founders.

A former Helius engineer made public allegations of workplace misconduct against Mumtaz, which he publicly denied.
