Stackup raises $4.2m to launch banking integration and simplify crypto business operations

Why is Stackup’s $4.2 million seed funding round seen as a critical step for crypto businesses needing unified operations?

Culver City-headquartered crypto infrastructure startup Stackup announced on June 21, 2025, that it has raised $4.2 million in seed funding, a move that supports its vision of eliminating operational fragmentation for businesses in the Web3 ecosystem. The investment round was led by 1kx, a venture capital firm known for backing early-stage crypto projects, with additional participation from institutional investors including Y Combinator, Goodwater Capital, Soma Capital, Amino Capital, and Digital Currency Group (DCG).

The funding coincides with the launch of Stackup’s latest product enhancement—direct banking integration—that aims to streamline operational workflows by connecting fiat and crypto financial systems. The expansion is expected to increase enterprise adoption of Stackup’s platform by enabling crypto-native businesses to run their operations on a unified system that blends traditional ACH capabilities with on-chain functionality.

Founded in 2021, Stackup initially gained traction by contributing wallet infrastructure to major players such as Coinbase and TrustWallet, experiences that laid the groundwork for its broader business-facing platform. Since then, it has pivoted toward providing full-stack digital asset management tools for companies navigating the challenges of multi-chain environments.

What are the operational pain points Stackup aims to solve for crypto-native companies managing fiat and blockchain systems?

Crypto businesses often face operational silos—juggling between traditional banking platforms for fiat transactions and decentralized wallets for digital asset activity. Stackup’s newly launched direct ACH integration addresses this gap by allowing users to initiate non-custodial fiat-to-crypto transfers within their current financial workflows. The integration supports direct connectivity between a company’s bank account and its Stackup-managed wallet, removing the need to engage third-party custodians or external platforms.

This development gives crypto enterprises the ability to conduct ACH transfers without relinquishing control over their assets, a critical feature in an industry that prioritizes decentralization and ownership transparency. The offering is designed for use cases ranging from payroll processing and vendor payments to treasury operations and institutional transactions.

Institutional investors are framing the integration as a pragmatic step toward real-world usability, noting that operational friction has been one of the chief barriers to crypto adoption at scale. By enabling businesses to merge both legacy and blockchain-based systems under a single interface, Stackup is positioning itself as a platform of record for crypto treasury and payment operations.

How does Stackup’s expanded blockchain support simplify decentralized financial operations for enterprises?

In addition to fiat integration, Stackup has added multi-chain functionality that allows enterprises to manage operations across major blockchain ecosystems. The platform now supports Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, and Binance Smart Chain (BSC)—a significant enhancement over prior versions that required businesses to manually bridge assets or operate multiple wallets across each chain.

With Stackup’s current platform, businesses can execute cross-chain transfers without relying on third-party bridges, which have often introduced security vulnerabilities. This allows for faster transaction execution, centralized audit trails, and reduced exposure to protocol-level risk.

Industry observers suggest that this level of interoperability is critical for Web3-native businesses operating in decentralized finance (DeFi), NFT infrastructure, or cross-border crypto payments, where asset mobility across chains is a daily requirement. By consolidating these actions under a unified dashboard, Stackup is helping businesses scale their operations while lowering operational complexity.

What role did Stackup’s earlier work with Coinbase and TrustWallet play in building its enterprise-grade platform?

Stackup’s founding team has deep roots in the Web3 wallet infrastructure space. Prior to launching its own platform, the company was involved in building secure and scalable wallet services for Coinbase and TrustWallet, both widely regarded as industry benchmarks for user-facing digital asset custody.

This background gave Stackup early exposure to the technical and compliance challenges associated with wallet development at scale—experience that has translated into its current platform, which offers multi-user controls, advanced permissions, and audit capabilities suitable for enterprise-grade usage.

Stackup’s model centralizes operational control while preserving decentralized asset architecture. Businesses maintain ownership of their wallets while being able to oversee, track, and optimize operations from a single point of command. This hybrid model is seen as ideal for companies that need a regulated-facing interface for interacting with on-chain systems without compromising on security.

How are investors and analysts evaluating Stackup’s market positioning in crypto enterprise infrastructure?

While crypto infrastructure startups have seen mixed sentiment amid broader market volatility, Stackup’s focus on operational tooling rather than token speculation has drawn attention from venture investors looking for product-led growth opportunities. Analysts view the firm’s bank-to-wallet ACH transfers and multi-chain command interface as solving long-term business pain points rather than chasing short-term hype cycles.

From a product-market fit standpoint, Stackup is emerging in a competitive but under-addressed niche: enterprise crypto financial management. Unlike custodial exchanges or DeFi protocols, Stackup’s platform is designed specifically for operational backend control—an area where even well-funded crypto firms often lack in-house expertise.

Analysts expect continued traction in this sector, particularly as mid-sized and institutional crypto businesses mature and seek to establish internal treasury systems, compliance workflows, and multi-user governance tools. Stackup’s recent funding provides the capital to expand platform integrations, enhance automation features, and scale go-to-market efforts.

What is the long-term outlook for Stackup as it continues developing crypto business infrastructure?

With $4.2 million in new funding, Stackup plans to accelerate platform development and scale its customer base within the enterprise Web3 segment. Key priorities include expanding direct bank integrations, increasing supported blockchain protocols, and adding workflow automation for recurring transactions, reporting, and governance.

The crypto infrastructure firm is also exploring strategic partnerships with financial institutions and enterprise blockchain providers, signaling a broader ambition to become a foundational layer in the crypto-to-fiat operational stack.

As regulatory frameworks begin to clarify and adoption among institutional players increases, Stackup’s approach to compliance-conscious, non-custodial operations could help it emerge as a preferred provider for digital asset businesses worldwide.
