A former European executive for Google and LinkedIn has joined WealthOS, the London-headquartered wealthtech SaaS provider, as Chairman.
Following a career spanning more than 30 years, John Herlihy brings to WealthOS a wealth of experience in leading European growth strategies for some of the world’s biggest online companies.
After spending many years in California leading teams for Adobe, Oracle and First Data, John returned to his native Ireland in 2005 to scale Google’s EMEA operations. He spent a decade building Google’s multi-billion dollar revenue engine through a 3,500-strong team. John then spent a further six years at LinkedIn as VP for EMEA and LATAM. Today, John holds numerous Non-Executive Directorships at high-growth European tech companies, including OpenAI (Ireland).
Founded in 2019 by Anton Padmasiri and Chamat Arambewela, WealthOS is a cloud-native, middle- and back-office SaaS provider. Its technology enables global wealth management businesses to confidently accelerate their adoption of digital tools - tools that improve not only how they work, but the experience they offer to their end-clients. The firm’s distinctive modular operating system creates 3x faster product development and reduces operational expenses by 40%.
John Herlihy, Chairman of WealthOS, comments: “What has impressed me most about WealthOS is the team’s innate ability to understand finance and technology equally. Anton and Chamat have deep, genuine domain expertise - a quality that I recognised from my first meeting with them. Many fintech founders have a great tech solution and are chasing a problem. That was never the case here. WealthOS has identified a fundamental problem in the plumbing that underpins the global wealth management market, and they’re building a modern, fintech-led way that not only resolves that issue, but removes complexity and creates enviable competitive advantage.”
Having joined WealthOS initially as an angel investor, John has become chairman at a pivotal moment in the company’s trajectory. Last month, WealthOS completed one of the largest migrations out of global wealth technology firm, FNZ, alongside its strategic partner, Quai Digital, a digital savings and investment platform services provider. The migration of 126,000 accounts was completed just seven months after Quai Digital won instruction from its client, The Children’s ISA. WealthOS technology powered the migration to Quai Digital’s operating platform in an all-in-one transition process - breaking from the industry’s more standard phased approach. The physical migration of data, cash and assets took just four weeks. This was WealthOS’s second successful migration in partnership with Quai Digital. By year-end, the partners expect to have migrated assets worth in excess of £400 million on behalf of Quai’s clients.
Anton Padmasiri, Founder & CEO of WealthOS adds: “Since John joined WealthOS, his depth of experience has had an immediate impact across our organisation. John is one of the rare executives who truly understands company scaling, he knows the critical breakpoints as companies grow and how to navigate them gracefully. Having operated at the highest levels of the technology industry throughout his career, John brings the pattern recognition and strategic perspective that only comes from guiding companies through transformative growth. 2025 has been a transformative year for WealthOS, one in which we’ve validated our vision and delivered exceptional value to our first customers. With John now stepping into the chair role, I’m confident that 2026 will be even more successful as we scale to meet the opportunity ahead.”
