Jon Grayem is the Co-Founder and Chief Executive Officer of Tabski, the company he founded in 2021 to build the definitive operating system for modern food halls and multi-vendor hospitality venues. Jon conceived and designed the entire Tabski platform, translating over a decade of firsthand operator and payments experience into a purpose-built product that no incumbent POS vendor had attempted. He previously served as President of TableCrunch (ADSZY LLC), a software platform that gave SMBs true marketing attribution by connecting offline card-present transactions — captured through the payment network — back to the email and social media campaigns that drove them. The company was acquired by Inc. 5000 honoree TRNXN. Jon was also a top-tier Channel Partner at Upserve (formerly Swipely, acquired by Lightspeed), ranking among the highest-performing resellers of the restaurant SaaS platform. Earlier in his career, he managed community banking centers for merchant processing — giving him direct, ground-level fluency with how payments, banking, and high-volume merchant operations actually work. A member of CoCard's President's Club, Jon's understanding of where payments, POS, and hospitality operations converge is the foundation on which Tabski was built. He holds a Bachelor of Business Administration from the Trulaske College of Business at the University of Missouri.

Filip Djordjevic is the Co-Founder and Chief Technology Officer of Tabski, where he leads the engineering organization responsible for Tabski's platform architecture, product development, and technical infrastructure. A graduate of the University of Belgrade School of Electrical Engineering, Filip previously founded Techie Farm and subsequently co-founded Apoddo, a software development organization now serving 100+ active client engagements across the United States — including AWS, Estée Lauder, and Memorial Sloan Kettering Cancer Center — with an engineering bench that attracts top-tier talent from companies like Tesla, Amazon, and SpaceX. His background spans full-stack engineering, platform architecture, and the operational scaling of software engineering teams, giving Tabski a technical foundation built for the reliability and throughput demands of high-volume hospitality environments.

He spearheaded Visa's cloud transformation for corporate platforms, modernizing mission-critical enterprise infrastructure across a globally distributed, highly regulated environment. He has led technology integration across 18 acquisitions and divestitures, including both sides of a $2B payments acquisition from pre-acquisition due diligence through multi-year integration, and serving as integration lead for corporate platforms and identity in one of the largest payments network acquisitions in history at $23B. At Tabski, Ninad brings the platform architecture depth, payments security expertise, and enterprise credibility that positions the company to serve large-scale hospitality operators and institutional partners. Beyond Tabski, he serves as CTO of Apoddo and as an Executive Advisory Board member of Myriad Venture Partners, a $100M early-stage venture firm investing in visionary AI, B2B software, and industrial transformation leaders.
