About us
John and Hazim founded Stackup in 2021.
We were pioneering a new standard for crypto wallets called ERC-4337, and quickly became the leading infrastructure provider. Stackup powered wallets for Coinbase, Trust Wallet, and many others.
But we discovered a deeper problem: the companies building the future of finance could barely manage their own onchain finances. Crypto companies were drowning in manual transactions, wrestling with hardware wallets, and losing precious time to administrative chaos.
So we transformed Stackup into something bigger—a smart account platform that brings modern financial operations onchain.

Our Mission
To empower crypto businesses with the operational excellence they need to scale.
We have modernized financial operations for crypto companies like Brex and Ramp did for traditional businesses.
Today, crypto companies use Stackup to manage millions in assets with the confidence of traditional banking while maintaining complete control.
We believe blockchain will become the backbone of global commerce. Until then, we're making sure operating onchain is your competitive advantage, not your biggest burden.
