Angela Sarno
VP, Marketing
For more than 20 years Angela has enjoyed working in start-up and scale-up companies, with a focus on communication roles in marketing, investor relations, and customer success, with two successful exits (for the same company! Long story.). She has had her hands in several product launches in SaaS including a closed-loop payment processing platform which served higher education customers and a mobile ordering app, and led a product turnaround for a niche market research company. She joined PaymentWorks in 2019 as the director of customer success and is currently responsible for building and delivering the marketing strategy.
What I love about PaymentWorks: The stress people have in trying to always be 100% right at their jobs is too much to bear. We eliminate that stress and allow people to focus on their jobs, not on the fear of making a mistake. We have their backs!
My favorite sport: CrossFit. Yes, I am calling it a sport. And I’d love to talk to you about it. Do you have three hours to spare?

Hayley also has extensive experience in startups, scaling fast-growing companies, sales, and business development for both Enterprise and SMB and has been involved in three successful exits with startups. Hayley’s background is in cybersecurity in the cloud, moving to B2B payments fraud has been a fun and interesting transition that allows her to leverage her cyber background.
What I love about PaymentWorks: Seeing Partners, Prospects, and Investors face light up when they learn what we do and how we do it. There is an amazing light bulb moment and then people realize this product can change the world – how we do business, individuals lives, and the fraud landscape. Also I love our customers and partners – they are our biggest champions, advocates, and are truly invested in making our product better.
My favorite thing to do: I love traveling. I am always up for an adventure to somewhere new. However, my favorite place in the whole world is Vermont. When I’m in Vermont I feel like I am home. I love when I’m there, life slows down. Everything seems easier, and the world is a prettier and a kinder place.

Taylor Nemeth
Vice President, Product
Taylor Nemeth
VP, Product
Taylor began his career in product management at the CBORD Group. While online ordering was still very much in its infancy, he was a principal architect of the first-to-market online ordering app focused on the higher ed market, GET. Taylor was also responsible for growing usage of CBORD’s payment platform from 20 customers to more than 200+ during his tenure, growth primarily fueled by the creation of the GET app.
He was an early employee at PaymentWorks, and has been instrumental in several product developments, including the company’s first-to-market payments security guarantee. He currently leads the Product team, responsible for the overall product vision & strategy.
What I love about PaymentWorks: The vision to go big!! We aren’t looking to find a niche or just grow a sales number by 10% each year… We want to fundamentally change the way companies do business with one another. The aspiration is exciting!
My favorite sport/place/hobby: Both types of football- American and soccer. Thailand. Playing guitar and mountain biking. (Not at the same time!)
Thayer Stewart
Chief Executive Officer
Thayer Stewart
Chief Executive Officer
Thayer has 35 years in B2B payments, starting at American Express, where he invented and then launched the first purchasing card, aka the P-Card, currently running at a trillion dollar annual payment volume. His next stop was Employee Matters, where the focus on payroll operations led to a key insight which was formative in PaymentWorks: with money movement you do not need to take control of funds. Finally with his time at OB10, his exposure to invoicing processing and invoice approval led to the epiphany that was the final key to the foundation of PaymentWorks: the vendor master is the vehicle to achieve payment security. He founded PaymentWorks in 2014 with CTO Alan Greenblatt. Thayer holds a BA from Princeton University.
My favorite thing about PaymentWorks: Building the team we have and seeing people grow and have an impact with their careers and with our customers. I was just the guy with the idea- it’s the people who work here who have made this idea a reality.
My favorite place: Hands down Maine. Spending time there in the summer with my family ranks really high. Oh wait, is it too late to say Paris?
Tom Hopkins
Chief Financial Officer
Tom Hopkins
Chief Financial Officer
Tom most recently worked with Rick Auletta as CFO of Motionsoft and Softgate Systems, resulting in successful turnarounds and sales of both companies. He has also served as CFO for iQ Media Group Inc. and E-Duction, Inc. He was Vice President of Finance at Bank One when it merged with J.P. Morgan, and was founder and CEO of EBL International, Inc., a payroll company focused on small-dollar loans in emerging economies. Tom is a graduate of Penn State University and holds an MBA from Villanova University.
My favorite thing about PaymentWorks: I love simple ideas that deliver outsized results. For most companies, new vendor onboarding is important, but error prone. And changes to vendor profiles introduce significant risk. Companies lose billions of dollars every year to fraudsters posing to be legitimate vendors; it just isn’t possible for every A/P department to be 100% vigilant against fraud. The PaymentWorks platform automates onboarding and updating of vendor records. But more than that, we can indemnify our customers against financial loss. Our proprietary IP and robust data sources provide a firewall between our customers and the fraudsters. It’s rewarding to work at a company that does well by doing good.
My favorite hobby: I like starting home improvement projects. Finishing them is not as fun.
