London-based FinTech startup Due secures €6.3 million and launches Stablecoin API for borderless payments solution

Due, a borderless payment startup founded by Revolut alumni, has extended its Seed round to €6.3 million to launch their new API platform, enabling businesses to seamlessly access stablecoin payments as blockchain technology reshapes global finance.

The round was led by Speedinvest, as well as participation from Semantic, Fabric Ventures, Strobe Ventures, Polymorphic Capital, and other investors, to further Due’s mission to allow anyone, anywhere to access borderless payment rails. This more than doubles its original €2.8 million raise.

Robert Sargsian, Founder & CEO of Due, says: “Moving money internationally still feels like sending a fax in the age of streaming. With Due, a single API line makes the world one currency zone, delivering real-time settlement at fair FX that’s five to ten times cheaper than legacy wires.”

Founded in 2022, Due empowers businesses with a seamless borderless account: a multi-currency account to send and receive funds directly between local and foreign fiat currencies, as well as stablecoins.

Alongside this, Due offers an embeddable API designed for FinTech companies. Whether Founders are building a payments platform, payroll system, crypto wallet, or neobank, they can reportedly access, send, receive, and settle global fiat and stablecoin transactions with a single integration. The company says their API embeds cross-border financial infrastructure directly into a customer’s platform, allowing them to scale faster, unlock new markets, and deliver a seamless global experience to users.

In both cases, Due offers real-time FX and settlement in 80+ markets with a single integration. This is achieved by stitching together local payment rails, liquidity markets, and blockchain networks into one unified infrastructure.

All transactions are routed through stablecoin and on-chain rails where possible, enabling mid-market FX rates and offering savings up to 90% on routine transactions compared to traditional banking infrastructure. By removing the need for multiple banking relationships, currency accounts, or regulatory setups, Due aims to turn global treasury into a simple endpoint.

Today, over 500 companies use Due to move money globally, including:

• Rainforest Builder (an international reforestation company) uses Due to fund tree‑planting projects, sending USD and settling in GHS, SLE, ZAR and more.
• Several regional neobanks now tap Due’s rails to offer customers virtual EUR and USD wallets, unlocking seamless, low‑cost international remittances.
• Extended (founded by former Revolut team members and now one of the fastest‑growing perpetual exchanges) is building instant, compliant on‑ and off‑ramps for traders in more than 80 countries using Due’s platform.
• A Mexico-based importer pays Chinese suppliers same‑day through stablecoin rails, avoiding costly SWIFT legs.
• Neverless (a crypto investment platform with zero fees, also ex-Revolut) leverages Due to enable instant on-ramp in high-value, emerging markets, such as UAE and Mexico.
• Ledn (a leading digital lending platform) leverages Due’s payouts feature for loan distributions to its customers worldwide.

Olga Shikhantsova, Partner at Speedinvest, says: “Cross-border payments remain one of the most stubbornly broken pieces of global finance – and stablecoins are here to fix it. Due is solving this not with another app, but with infrastructure: a single, compliant API that simplifies transactions across both fiat and stablecoin rails. We backed the team early on and are excited to now lead this round as they scale the platform into a true global standard.”

The fresh capital will be used to extend and scale Due’s Global Stablecoin APIs, enabling faster, broader access to real-time settlement infrastructure. Due aims to increase its coverage to over 100 countries in terms of payments rails and currencies by the end of the year.

Due will also build more payment solutions, including invoices, cards and yield accounts, and hire engineering and compliance talent to support its exponential growth accordingly.
