What our clients are saying

Daniel Rubini

Head of Technical Accounting, Financial Reporting and SOX, Liquid Death

"Working with Connor Group was like having my own in-house full technical accounting squad. They truly became an extension of my team. Their experience and expertise were evident from the start, and they required no ramp-up time. They jumped right in and started delivering results. Their ability to quickly understand our needs and work within tight timelines was impressive. What they brought to the table made all the difference and was invaluable to our success in completing the financial statements and our audit."

Ted Monohon

CAO, Nusano

"Connor Group made my life a lot easier! Having a deep understanding of our business, they worked directly with our auditors, translating complex requirements into actionable steps for our team. They took on the accounting research burden and presented us with clear options - empowering us to make intelligent decisions. Connor Group simplified GAAP compliance, making the entire audit process less daunting. These are the kind of people you want to work with!”

Janine Korovesis

VP Controller, OpenAI

"OpenAI was changing fast, but I knew I didn't want to prematurely grow a really big internal team. I needed our financials to be sound and reliable, and something that I could speak with confidence about. So it was a no-brainer. Connor Group came in. Then they helped me set up an ERP within 90 days. I was very realistic about what I knew Connor Group could do for me—in short order—versus what I could do for myself."

Jessica Wijesekera

Senior Vice President of Global Accounting, Vytalize

"Vytalize Health onboarded Connor Group one year ago to mow through ten years of overgrown technical accounting matters. We’ve kept our Connor Group colleagues on board because they’ve given our team access to resources, finding the right answers five times faster; we even expanded their services into system implementations because they help us move more quickly."

Greg Ray

Head of Business Systems, HubSpot

“Connor Group has been a trusted partner of HubSpot over the years, most recently conducting a thorough health check and Opportunity to Cash (O2C) assessment to help us optimize for growth. They were able to easily understand our proprietary systems, identify growth inhibitors and distill improvements into actionable steps. Thanks to their insights, we've finalized build vs. buy decisions and aligned development priorities to better serve our customers. Connor Group isn’t just a consultant—they’re a true growth accelerator, enabling our vision of creating a world-class buying and billing experience."

Georg Nalbant

Director Finance Excellence, Valneva

“We engaged with Connor Group at a critical juncture, facing challenges in our Internal Controls over Financial Reporting. Their support to our team was nothing short of exceptional. They had the capability and agility to step in seamlessly and with unwavering commitment. Thanks to this strong collaboration, we have a robust and effective ICFR framework that provides a solid foundation for ongoing compliance and control. I’m genuinely grateful for their partnership and incredible value. We continue working with Connor Group to support planned changes in our ERP environment.”
