👋 About Us
NALA is building Payments for the Next Billion. Faster, smarter, and fairer transfers for everyone. Since 2022, we’ve grown our business 120x, grown the team from 9 to 150+, raised $50M+ from top-tier investors, and were named to the Forbes Fintech 50 in 2025.
We operate two core products:
- NALA, our consumer app making cross-border payments cheaper, faster and more reliable for the global diaspora. Allowing users to send money from the UK, US and EU to Africa and Asia.
- Rafiki, our B2B payments infrastructure, is powering global payments.
Our team includes alumni from Wise, Stripe, Monzo, Revolut, and CashApp — operators who’ve scaled world-class products. We act with urgency, think deeply, and put our customers first always.
At NALA, this isn’t just a job. It’s ownership, impact, and the chance to change global payments forever.
