Sales tax has gotten harder, very quickly. A growing ecommerce brand can owe tax in dozens of states. A SaaS company can have nexus in 20+ jurisdictions before their 50th hire. And telecom providers? They juggle hundreds of jurisdiction-specific taxes, surcharges, and fees, all with constant regulatory changes. Every industry has its own maze of rules, and getting it wrong is expensive.
We’ve spent over 30 years in the trenches of indirect tax, founding two successful tax companies and delivering solutions for thousands of businesses. We’ve seen every edge case, every regulatory curveball, and every limitation of legacy systems. So we built CereTax — the first cloud-native, AI-powered platform designed by sales tax experts to handle the complexity of today’s business environment.

Michele knows product inside and out. From driving digital transformation at Verizon to shaping tax tech at Avalara, she’s spent her career building tools that actually make life easier.

Kelsey VanArtsdalen lives and breathes sales tax and somehow makes it look easy. With over a decade in the space and a track record of simplifying the most complex implementations, she’s a go-to expert for all things compliance. When she’s not solving tax headaches at CereTax, she’s likely chasing adventures (or her pup) somewhere far from a spreadsheet.

Eric Schaefer, JD, CPA speaks fluent sales tax and Python. With a deep background in telecom tax, regulatory complexity, and process automation, he’s the go-to for making messy compliance problems feel solvable.
Kelly Davis is "The Sales Tax Guy" for a reason. With deep roots in the NetSuite ecosystem and a knack for solving tough compliance problems, he’s helped hundreds of businesses get sales tax under control and actually enjoy the process (yes, really). If it involves tax tech, partnerships, or cool socks, Kelly’s in his element.
Michael Yokay has lived telecom from every angle—regulatory, revenue, and the real-world mess in between. Now he’s helping companies automate the sales tax part without the headaches. He’s seen it all, fixed most of it, and probably has a telecom story that’ll make your jaw drop.
André Jones is a Senior GIS Analyst at CereTax, where he transforms tangled jurisdictional data into clean, audit-proof clarity. He’s got a knack for tax maps, metadata, and making sourcing logic sound (almost) fun. Ask him about rooftop accuracy—or his latest playlist.
Mike has been building and scaling tax technology for decades, including founding SureTax before it was acquired by Wolters Kluwer. With CereTax, he’s rewriting the rules of sales tax automation—pairing modern tech with real tax expertise to finally fix what legacy systems couldn’t. Fearless about complexity and relentless about customer success, Mike leads CereTax with the belief that sales tax should never slow a business down.
The smartest minds in tax, tech, and growth saw what we were building—and wanted in. Our investors fuel our mission to finally fix sales tax for good.
