Our Team

Bill Meara is Chairman & CEO of HALO Cyber, where he is leading the company's mission to simplify how businesses manage cybersecurity, compliance, risk, and cyber insurance through one integrated platform.

A longtime entrepreneur, operator, investor, and advisor, Bill has spent his career building, scaling, and investing in businesses across cybersecurity, insurance, technology, media, and private equity.

Prior to HALO Cyber, Bill served as President & CEO of Acrisure Cyber Services, helping build and lead the cybersecurity and technology business within one of the world's fastest-growing insurance and fintech organizations. During his time with Acrisure, the broader company scaled from approximately $38 million to more than $4 billion in revenue, completed hundreds of acquisitions globally, and expanded its international footprint.

Bill also serves as an Operating Partner at ABRY Partners, where he works alongside management teams and investors across technology, media, communications, and business services. His work has included leading a $100 million investment in Kevin Hart's media platform and helping develop strategic partnerships across the ABRY portfolio.

Before entering cybersecurity and insurance, Bill built and led multiple media and technology companies. He co-founded Vector Media and Fuel Outdoor and later served as Chairman & CEO of Access Sports Media (ASM). During his seven-year tenure at ASM, revenue increased approximately 500% and EBITDA approximately 800% as the company developed a network spanning professional and minor-league sports venues across North America. His career has included partnerships and commercial relationships with organizations including Live Nation, Ticketmaster, CAA, UTA, Wasserman, Endeavor, Google, Apple, Nike, Coca-Cola, HBO, Universal Pictures, AT&T, and CBS.

Across his career, Bill has operated on both sides of the table — as a founder and CEO building companies, and as an investor and advisor helping leadership teams create enterprise value.

At HALO Cyber, he brings those experiences together to address one of the most significant challenges facing modern businesses: understanding cyber risk, strengthening security and compliance, and securing the right insurance coverage without navigating a fragmented ecosystem of vendors and solutions.

Bill has also served on the Board of Big Brothers Big Sisters and as a senior advisor to technology and media organizations. He is a longtime supporter of lacrosse, including programs at Canterbury School and Trinity College.

Matthew Belkin, a Boston-based operating executive and P&L leader, has successfully built and scaled technology-enabled and services businesses in both private equity-backed and public company environments. He collaborates with CEOs, boards, and investors to drive growth and expand margins. Additionally, he enhances operational rigor across full P&L ownership, M&A integration, and go-to-market leadership in cybersecurity, FinTech-adjacent services, and live entertainment. His thought-leadership has been featured by publications such as The Wall Street Journal and Insurance Insider.

Most recently, he served as Chief Operating Officer and Head of Cyber Services at Acrisure, where he built and scaled the firm’s IT and cybersecurity services platform for mid-market businesses. Recruited by Abry Partners, he led a 200+ person organization and owned full P&L accountability for a $50M+ business — growing the division from $2M to $50M+ ARR in three years through a mix of organic growth and acquisition integration. During his tenure, the business delivered 18% organic growth, deployed $75M+ of capital, and integrated four acquisitions to improve scalability and operating efficiency. He also launched Simple Cyber, an SMB-focused cybersecurity product, and built a revenue engine that won marquee clients including the PGA Tour and Oak View Group.

Matthew previously spent nearly two decades at Live Nation Entertainment, including eight years as Vice President of Product Management within Media & Sponsorship. He led product and monetization across digital media and sponsorship platforms, generating $50M+ in contribution margin, launching new revenue streams such as a digital out-of-home media network, and rolling out RFID/cashless payment experiences at festivals that unlocked $15M+ in incremental sponsor revenue. Earlier roles spanned enterprise revenue strategy, national sales leadership, and strategic partnerships, supported by a strong operating cadence and forecasting discipline.

Matthew serves on the advisory board of eXpanded eXistence (eXeX), an AI-powered surgical intelligence platform recognized by Time as a Best Invention of 2024, and he volunteers with community meal programs supporting families at Boston Children's Hospital. He holds an MBA from Babson College and a BBA from American University.
