Digital asset management startup Stackup has raised $4.2 million in seed funding to help crypto businesses streamline their operations. The round was led by 1kx, with additional backing from Y Combinator, Goodwater Capital, Soma Capital, Amino Capital, and Digital Currency Group.
Founded by former SpaceX mission manager John Rising, Stackup initially provided wallet infrastructure to giants like Coinbase and TrustWallet. The company has since shifted its focus to building an end-to-end digital asset management platform for businesses in the crypto space.
With the new funding, Stackup has launched a direct banking integration feature, bridging the gap between traditional finance and blockchain systems. This enables non-custodial ACH transfers directly between connected bank accounts and crypto wallets, fitting seamlessly into existing business payment flows.
The platform also now supports a wider range of blockchains, including Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, and Binance Smart Chain, expanding its utility for Web3-native enterprises.
CEO John Rising says, “This funding gives us the ability to eliminate operational inefficiencies that have historically hindered the adoption and growth of this industry. We’re empowering businesses to streamline their financial operations and workflows, allowing them to focus on growth without compromising on security or control of their assets.”
