Who we are 

Picnic is reinventing meals at work. We partner with top local restaurants and deliver lunches to companies from 20 to more than 10,000 employees. This allows us to deliver high-quality, individually packaged meals without fees or tips. The result is a joyful experience for employees, teams, and entire organizations. Companies can design their employee food offerings, ranging from simple lunches to sophisticated meal programs. We are obsessing about each company, each customer, each restaurant, and each individual order. Picnic creates a more sustainable model for restaurants, helping local heroes to succeed.

Picnic's early business signals have been exceptionally strong. It has been adopted organically by companies from Banking to Manufacturing, from Tech to Government. Customers are discovering and advocating for the product before any marketing. Since launch, we have grown exponentially and are now entering the 10 100 scale phase as we expand across major North American markets.

Picnic owns the full stack that powers workplace food delivery: client applications for employees, company managers, kitchen operations, and courier operations. AI-powered services are tying them together. This vertical ownership allows us to tightly integrate ordering, logistics, and operations to deliver reliable, cost-efficient services at scale. We are solving one of the most comprehensive, and therefore complex, meal delivery problems. We need YOU to help us build it at scale!
