PairSoft names Brian Rigney as Chief Executive Officer

PairSoft has appointed Brian Rigney as Chief Executive Officer, bringing in a software and fintech executive who has previously held four chief executive roles.

Rigney takes the top job as PairSoft looks to strengthen its position in procurement and accounts payable software for finance teams. Its products are designed to work within existing enterprise resource planning systems rather than alongside them as separate tools.

His appointment puts an executive with experience across enterprise software, digital commerce and financial technology at the head of a business focused on back-office automation. PairSoft sells invoice automation, procurement and payments software to enterprise and mid-market customers, with integrations across systems including Oracle, Microsoft Dynamics, Sage Intacct, Blackbaud, NetSuite, Plex and Infor SyteLine.

Before joining PairSoft, Rigney was Chief Executive Officer of CAI Software, an ERP platform for middle-market manufacturers, producers and distributors. Earlier, he served as Chief Executive Officer of FASTR, a digital experience and conversion rate optimisation platform for enterprise commerce teams.

He also founded a fintech payments start-up, adding entrepreneurial experience to a career otherwise rooted in larger software businesses. That mix may prove relevant for PairSoft as software companies serving finance departments face pressure to balance product development with tighter commercial execution.

Investor backing

PairSoft investor TA Associates backed the appointment and pointed to Rigney's record of scaling software businesses. TA has invested in PairSoft since 2025 and is a longstanding private equity investor in technology, business services, financial services and healthcare.

Harry Taylor, Managing Director at TA Associates, said Rigney was a strong fit for the company's next phase.

"We are thrilled to welcome Brian as the new CEO of PairSoft," said Harry Taylor, Managing Director at TA Associates.

"Brian's proven ability to scale enterprise software businesses, build world-class teams, and drive customer-centric innovation makes him the ideal leader to accelerate PairSoft's global growth and expand the value the company delivers to its customers," Taylor said.

The appointment comes as software suppliers to finance departments compete on how deeply their products are embedded in core accounting and ERP systems. Procurement and accounts payable software vendors have increasingly argued that tighter integration can reduce manual work and avoid the process gaps that emerge when teams rely on separate applications.

PairSoft has made that case with its own offering, arguing that finance teams often face workarounds when using products that are not native to the ERP systems running key processes. Its focus on the office of the Chief Financial Officer places it in a segment where software buying decisions are often tied to cost control, auditability and process consistency.

Market pressure

The leadership change also comes as software vendors push artificial intelligence features into finance workflows. Procurement and accounts payable are areas where suppliers have promoted AI tools for tasks such as invoice handling, approvals and exception management, though customers have often taken a cautious approach where compliance and controls are involved.

Rigney referred to that broader shift in his comments on taking the role.

"I am excited to join PairSoft at such a pivotal moment for the market where AI solutions and the SaaS model are converging to redefine how businesses operate," said Brian Rigney, Chief Executive Officer at PairSoft.

He also highlighted the company's existing customer base and its focus on finance leaders.

"PairSoft has an exceptional track record for customer centricity and understanding the real pain points of finance teams and CFOs. I look forward to working with this talented team to build on this strong foundation, expand our reach, and deliver even greater value to the loyal and ever-growing customer base we serve," Rigney said.

For PairSoft, the challenge now is to turn a leadership change into sustained growth in the crowded finance automation software market. Vendors in this sector must persuade customers not only that automation can reduce administrative work, but also that the software can operate reliably within complex ERP estates that often include multiple business units, legacy systems and strict internal controls.

Rigney's background may help on both fronts. CAI Software gave him exposure to ERP customers in industrial and distribution markets, while FASTR and his fintech start-up added experience in digital commerce and payments. Those areas increasingly overlap in finance software, where procurement, invoicing, approval workflows and payment execution are becoming more connected.

TA Associates, which has raised USD 65 billion in capital to date, has invested in more than 560 companies since its founding. Its support for PairSoft suggests it sees room for further expansion in software for the finance function built around existing ERP infrastructure.

With deep integrations into finance ERPs including Oracle, Microsoft Dynamics, Sage Intacct, Blackbaud, NetSuite, Plex and Infor SyteLine, PairSoft is positioning itself around software that works inside the systems finance teams already use.
