PAR Technology Corporation (NYSE: PAR) announced the launch of Guest360, a customer data platform designed to help restaurant brands build unified profiles of their entire guest base, including guests who are not enrolled in loyalty programs.

Guest360 is built to integrate with PAR's existing Punchh loyalty software, which the company says serves more than 200 enterprise restaurant brands. The new product is already live with select Punchh customers, with a broader rollout to all Punchh customers planned through the end of 2026.

The platform uses a feature called Profile Stitching to consolidate guest activity from multiple channels — including point-of-sale, kiosk, drive-thru, mobile app, and delivery — into a single guest profile. According to PAR, most restaurant transactions occur outside loyalty programs, leaving brands with guest data that is often anonymous or fragmented across systems.

Guest360 connects directly to Punchh, allowing restaurants to create audience segments and trigger campaigns such as personalized offers, win-back journeys, and loyalty enrollment without exporting data to a separate marketing platform. The product also includes closed-loop measurement that ties campaign results back to POS transactions and item-level revenue.

"Most restaurants know their loyalty members well, but that's only a fraction of their guests," said Savneet Singh, CEO of PAR Technology. "Guest360 is a customer data platform, natively integrated into the PAR Punchh suite, that unifies every guest interaction into a single profile."

Guest360 also connects to PAR Intelligence, a product that generates audience and campaign recommendations based on data surfaced by Guest360.

PAR said Guest360 was developed in partnership with Punchh customers and a product advisory group. The company plans to exhibit at the FS/TEC conference, booth #311, from September 23–25, 2026, where it will offer in-person demonstrations of Guest360 and PAR Intelligence.
