Our Story
Gauntlet was founded in 2018 by Tarun Chitra, CEO, and Rei Chiang, CTO. The company was developed from Tarun’s years of creating computational simulations in physics, bimolecular systems, applied math, and eventually crypto. Rei built marketplace simulations for self-driving vehicles and spent five years in the HFT industry as a portfolio manager and quant trader. In 2017—after speaking with crypto exchanges and base layer protocols—Tarun and Rei saw an untapped product opportunity to build a platform that could stress test and evaluate smart contracts and protocols. Armed with this insight, they raised capital and started Gauntlet. Full story here

Tarun is an alumni of D. E. Shaw Research (DESRES), Vatic Labs, an HFT firm, and Cornell. He fell into the blockchain world in 2011, when he was working on ASICs at DESRES and observed Bitcoin ASIC mining rigs substantially delay DESRES’s ASIC production. He has spent the last seven years working on simulation-based R&D at the intersection of high-performance computing and AI and is applying this knowledge to the blockchain ecosystem.
