Crypto finance platform Stackup has secured $4.2 million in seed funding, led by 1kx, with participation from Y Combinator, Goodwater Capital, Soma Capital, Amino Capital, and Digital Currency Group. The raise will support Stackup’s mission to streamline operational complexities for businesses dealing with both fiat and crypto, while accelerating new product development.
This announcement coincides with the rollout of a direct banking integration, designed to eliminate the fragmentation between traditional finance systems and crypto wallets. The feature allows businesses to connect their bank accounts directly to their Stackup wallet, enabling non-custodial ACH transfers without relying on intermediaries.
Crypto businesses have long struggled with maintaining parallel systems—traditional banking for fiat operations and crypto tools for on-chain activity. Stackup aims to bring these systems under one roof. By enabling seamless, secure transfers within existing payment workflows, it eliminates the need for third-party custody and reduces operational friction.
“Our mission at Stackup is to provide businesses with the tools they need to manage their digital assets with the same level of efficiency and control they expect from traditional financial systems,” said John Rising, co-founder and CEO of Stackup.
The company also announced expanded blockchain compatibility, now supporting Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, and BSC. This addresses a persistent challenge for multi-chain businesses, which previously needed to operate across various wallets and bridges—often leading to time-consuming and risky asset transfers.
“Crypto businesses have largely struggled to address their operational needs due to the unique burden of managing assets on multiple chains,” said Nichanan Kesonpat of 1kx. “Stackup is addressing those critical pain points and enabling businesses to take control of their funds in one seamless, secure, and scalable platform.”
With the fresh capital, Stackup plans to invest in platform development, focusing on adding more automation, improving UI/UX, and expanding integrations with both crypto and banking tools. The company is also preparing to roll out new analytics and reporting tools to support businesses managing high volumes of crypto transactions.
In addition, the team aims to grow its customer base among mid-to-large-sized crypto businesses while preparing for regulatory developments by adding compliance-ready features to the platform.
Founded in 2021, Stackup first established itself by building wallet infrastructure for major players like Coinbase and TrustWallet. That early experience laid the groundwork for its current platform, which helps businesses take control of digital assets through a unified dashboard.
Stackup offers centralized visibility over decentralized activity—without compromising security. With an emphasis on real-time control, automation, and transparency, the company is focused on reducing complexity in crypto operations while giving businesses confidence in how they manage their funds.
In addition to lead investor 1kx, the seed round included participation from several notable backers: Y Combinator, Goodwater Capital, Soma Capital, Amino Capital, and Digital Currency Group. These firms bring not only capital but deep experience in Web3 infrastructure, fintech, and startup scaling.
