ISH Launches New Fintech Track with Acquisition of ProSpend

ISH today announced the acquisition of ProSpend, a Sydney-headquartered spend management software company. The deal marks the launch of ISH’s new Fintech track, expanding the firm’s portfolio beyond worktech and compliance. It creates a platform for ProSpend to establish itself as a leading solution provider in Australia and New Zealand, while scaling its ambitions across the UK & Ireland.

ProSpend’s all-in-one platform helps finance teams automate expense, invoice and payment workflows, reducing manual administration and improving spend visibility, control and auditability. Trusted by more than 1,000 businesses, including Nike, the World Wildlife Foundation (WWF), and KFC, the company has, in recent years, broadened its position as a leader in the business spend management market, valued at more than $19 billion USD globally and projected to grow at an annual rate of 11.9% by 2030 to reach more than $46 billion.

“Fintech is a natural next step for ISH. ProSpend solves real-world finance challenges with elegant, enterprise-ready software, and we see a clear path to rapid growth across our core markets,” said Adam Reynolds, CEO at ISH. “We’ll bring go-to-market support, capital and our operational expertise to help ProSpend land and expand in the UK, Ireland and Europe, while keeping product focus exactly where customers want it: control, visibility and time back for finance teams.”

Consolidating expense management

Expense and spend management remains one of the most fragmented categories in fintech. Mid-market and enterprise finance teams still juggle multiple point solutions for invoices, expenses, cards, approvals and policy control, creating gaps in visibility, manual effort and compliance risk. ProSpend’s proactive approach—approvals and policy controls before spend occurs—directly addresses those visibility gaps while keeping teams in their current accounting stack. ISH’s Fintech track will target this fragmentation with a structured acquisition and build-out strategy, bringing together best-in-class products and teams to create a unified operating layer for finance.

This disciplined approach mirrors ISH’s proven playbook in its HR track, where selective acquisitions and focused integration have delivered category leadership, sharper go-to-market execution and measurable value for customers. The Fintech track will apply the same operator-led rigour, backing specialist teams, prioritising UX and trust, and compounding growth through complementary M&A.

Deep fintech experience

ISH is led by CEO Adam Reynolds and Chairman Michael Richards, both of whom have a decade-plus track record in financial workflow software. The pair previously scaled Webexpenses from a growth-stage UK innovator into a mature, international platform before exiting to ELMO Software in Australia. That journey, covering product expansion, multi-region go-to-market, enterprise-grade security and successful integration post-acquisition, underpins ISH’s hands-on model. Their experience gives ISH an edge in identifying durable fintech revenue, implementing compliant, scalable infrastructure, and orchestrating acquisitions that add genuine customer and shareholder value. The Fintech track plays directly to this expertise, via financial workflows, controls, and the data plumbing that connects them.

As part of ISH, ProSpend will invest in local hiring, partnerships, and customer success to serve growing demand in ANZ and expand into UK&I markets while maintaining the same platform, support experience, and service levels that the company’s 1000+ existing customers have come to expect.

Sharon Nouh, CEO of ProSpend, adds, “Joining ISH gives us the platform and expertise to realise our next stage of growth. The UK and Europe represent a huge opportunity for us, and with ISH’s backing, we can scale faster, strengthen compliance and security, and invest further in our product and customer success. Most importantly, it allows us to continue our mission of helping finance teams take control of company spend, wherever they operate.”
