Since joining Accountability in 2020 as President, Judd Rubin has spearheaded a period of remarkable growth, increasing recurring revenue more than fivefold while maintaining a client retention rate above 99%. His leadership emphasizes a product-led strategy, fostering strong client relationships and delivering solutions that address the unique needs of advertising and marketing agencies.
“My vision from day one was to build a financial platform that truly understands agencies—one that doesn’t need to be reprogrammed to fit their business,” said Accountability founder Terry McMillan. “Judd recognized how rare that is, and he’s been unwavering in preserving that focus while turning it into real, sustained momentum. What we’ve accomplished together is rooted in trust, clarity, and a shared belief that the best way to grow is by solving real customer problems—and making sure those solutions show up in the product. As he has proven, Judd will continue raising the bar, always with our customers’ success at the center.”
Rubin added, “Terry had the foresight to build a platform that supports the unique workflow of agencies. That clarity of purpose is what allows us to compete against the big-box sales behemoths and win. Terry’s vision is the reason we’re not just another ERP with a new coat of paint. Agencies were forced to retrofit generic software built for other industries—configuring and customizing systems just to make them usable. The difference with Accountability is that the nuance is already there, out of the box. That’s what makes it powerful. And it’s not just the product—it’s the people behind it. Everyone on our team has agency and finance experience, and that informs everything we do. We’re never going to deviate from that. This is personal for us. We’re not going to allow generic systems and legacy software to thwart agency growth.”
Accountability provides real-time margin visibility, automated financial workflows, and a global-ready infrastructure, serving agencies in over 30 countries. Clients praise its tailored functionality: “With Judd and his team at Accountability, we found people who shared our ethos of independence and a spirit of entrepreneurship and problem solving that you just don’t get with big software firms,” said Kamran Asghar, Global CEO, Crossmedia. “When you have massive ambitions, and you’re not part of the traditional solution, it’s always great to talk to fellow people who know how to scale businesses in times like this. Judd never shies away from attacking a problem himself and looking at it from the lens of which we operate. With big box solutions, you just don’t get that kind of personal touch and innovative perspective.”
Rebecca Mahadeva, CFO, Excel Sports Management, noted, “We worked with mass market platforms that lacked the understanding of our business. Accountability’s modular approach – with full integration of project costing and general ledger functionality – was a huge benefit out of the box for us. And because of Accountability’s agility, we were able to implement the system cheaper, on a quicker timeline and in a less disruptive way than with their competitors. I have great respect for Judd because what he sold me is exactly what he and his team delivered.”
Alberto Baez, CFO, Cartwright, WPP, added, “I insisted on Accountability, a system we had at Wieden+Kennedy, and I wasn’t willing to compromise for anything less. Judd provides a genuine partnership, not a ‘salesman’ one. He’s straightforward and available whenever we need him. By choosing Accountability, we avoided many growing pains through its tailored functionality that fits our specific environment. The intuitive UI feels purpose-built for our needs. Moreover, it offers exceptional flexibility while preserving the depth and richness required for controls.”
“We’re proud of what we’ve built, but there’s still so much more we can do to help agencies grow with confidence,” Rubin concluded. “By focusing exclusively on one vertical, we’re able to prioritize what matters most: actionable AI-powered insights, smarter resource allocation, and clearer visibility into client profitability. These are the areas we continue to invest in—guided by experience, and by what our customers have consistently asked for. As we grow, it will be my responsibility to ensure that Accountability remains the partner agencies rely on—not just for tools, but for trust, transparency, and the overall health of their business. As an independent, owner-operated company, Accountability answers only to its customers and team—allowing us to prioritize product decisions that directly reflect the needs of the agencies we serve.”
Accountability’s focus on agency-specific solutions and Rubin’s leadership ensure the platform remains a trusted partner for advertising and marketing agencies. With a commitment to innovation and client success, the company is well-positioned to drive global expansion and empower agencies to thrive in a competitive landscape.
