Olo is a SaaS company that builds software for restaurants and food brands to manage and grow their digital ordering and delivery operations. Its products sit at the point where a customer places an order, a restaurant fulfils it, and the business needs to keep the experience consistent across channels. In practice, that means helping restaurant groups handle online ordering, delivery integration, and the operational workflows that sit behind high order volumes, while also supporting the data and reliability requirements that come with taking payments and routing orders accurately.

HQ: Redwood City, United States • Information Security • Identity Management • 1001-5000 employees • Est. 2021 • Trust B • Hiring 71, 5 new
Delinea is an American security company created in 2021 when Thycotic and Centrify were merged under Thoma Bravo ownership, combining two long-established privileged access management vendors. Its products control and record the use of administrative credentials, service accounts and machine identities, which is the category regulators and cyber insurers most consistently require organisations to address. Headquartered in Redwood City, it sells to enterprises and public bodies and competes principally with CyberArk in a market where a single compromised administrator account is usually how a breach escalates.
