Rain Raises $58 Million Series B to Build the Future of Global Money Infrastructure
August 31, 2025
byFenoms Startup Research

Rain, a fast-growing fintech startup building financial infrastructure for the digital economy, has successfully raised $58,000,000 in its Series B funding round. The round was backed by a stellar lineup of global investors, including Sapphire Ventures, Dragonfly, Galaxy Ventures, Endeavor Catalyst, Samsung Next, Lightspeed, and Norwest.
Founded by Farooq M., Rain is building a “full stack for the full flow of money”, designed to help businesses unlock the benefits of stablecoin-backed payments and global financial accessibility. With this new injection of capital, Rain plans to accelerate product development, expand global partnerships, and scale its financial infrastructure platform for enterprises and institutions worldwide.
The Product: Full-Stack Financial Infrastructure
At its core, Rain is reimagining the financial system for a world that is increasingly digital-first. Traditional payment rails are slow, fragmented, and costly—especially when it comes to cross-border transactions and settlement. Rain solves this problem by offering a full-stack infrastructure platform that enables:
- Stablecoin-backed payments that combine blockchain efficiency with the stability of fiat.
- Faster cross-border transfers, eliminating the bottlenecks of traditional banking.
- Lower transaction costs, especially for enterprises scaling across geographies.
- A developer-first approach, making integration seamless for businesses looking to adopt Web3-powered financial services.
Rain’s platform empowers enterprises to unlock speed, flexibility, and reach while ensuring compliance and security at scale.
Why This Matters Now
Global payments remain one of the most broken aspects of financial services. According to McKinsey’s Global Payments Report, international transaction costs alone account for over $120 billion annually, largely due to outdated rails and intermediaries. Settlement times can still take days, slowing down commerce in a world where digital transactions happen in seconds.
At the same time, the adoption of stablecoins has exploded, with transaction volumes surpassing $7 trillion in 2022 alone (CoinMetrics). Stablecoins are quickly becoming the backbone of digital finance, offering businesses a reliable, transparent, and faster alternative to traditional currencies.
Rain’s strategy is to sit at the intersection of these shifts, making stablecoin-powered financial infrastructure enterprise-ready.
Here’s the ultra value drop for founders: the biggest opportunities often emerge where systems are universally painful but rarely challenged. Payments is a centuries-old problem—slow, opaque, and costly—but because it underpins everything, many startups shy away from it. Rain leaned in, tackling one of the hardest infrastructures to rebuild. The lesson? Don’t just look for emerging problems; look for old, entrenched ones that technology can finally solve at scale. These are markets where demand isn’t optional, where the pain is felt daily, and where incumbents are often too entrenched or too slow to adapt. For founders, Rain is a reminder that the boldest wins often come from rethinking the “boring but broken” backbones of our economy.
Industry Outlook: The Digital Money Revolution
The global financial landscape is being transformed by digital assets and blockchain-backed solutions. Key trends fueling Rain’s growth include:
- Cross-Border Growth: The global cross-border payments market is expected to hit $250 trillion by 2027, with enterprises demanding faster and cheaper alternatives.
- Stablecoin Momentum: Stablecoins already account for the majority of blockchain transaction volume, signaling mainstream adoption.
- Institutional Adoption: Large banks and financial institutions are now exploring stablecoin settlements and tokenized assets.
- Regulatory Clarity: More governments are providing frameworks for digital asset payments, opening the door for compliant, enterprise-grade solutions.
Rain’s positioning as a compliant, enterprise-focused infrastructure layer makes it one of the best-placed players to capture this massive shift.
The Investor Edge
The caliber of Rain’s Series B investors highlights the strategic importance of its platform:
- Sapphire Ventures: Known for backing enterprise leaders in fintech and SaaS.
- Dragonfly & Galaxy Ventures: Leaders in blockchain and digital asset investments.
- Samsung Next: Signaling strategic interest from global technology giants.
- Lightspeed & Norwest: Renowned VCs with a track record of scaling category-defining companies.
Together, this investor mix brings not just capital but deep networks across fintech, blockchain, and enterprise technology.
What’s Next for Rain
With $58 million secured, Rain plans to:
- Expand product capabilities, particularly around stablecoin-based settlement.
- Build deeper partnerships with enterprises, banks, and financial institutions.
- Invest in regulatory compliance to scale responsibly across jurisdictions.
- Expand global operations, focusing on emerging markets where traditional banking rails are weakest.
Rain’s ultimate goal is to build the default infrastructure for the flow of money in the digital age.
Final Thoughts
Rain’s $58 million Series B funding isn’t just another fintech milestone—it’s a signal of how quickly financial infrastructure is being reimagined. By offering enterprises the ability to leverage stablecoin-backed payments at scale, Rain is addressing one of the most fundamental bottlenecks in the global economy.
For founders, the insight is powerful: markets that seem too big, too slow, or too entrenched often hide the greatest opportunities. By tackling something as foundational as payments, Rain shows that solving old problems with new tools can create category-defining companies.
