Tello

Tello (Tello Applications, Inc.) was a customer-feedback and customer-service ratings startup founded in 2010 in Palo Alto, California by Joe Beninato and backed by 500 Global. It offered a free web and mobile application that let consumers rate and comment on their in-person service experiences at businesses (including feedback on specific employees), and sold businesses paid dashboard access to monitor how their staff were rated. The company has since shut down; no live product, developer program, or public API surface remains, so this record is retained as a defunct-company profile rather than an active provider for enrichment.

Tello is profiled on the APIs.io network. Tagged areas include Company, Customer Feedback, Customer Service, Reviews and Ratings, and SaaS.
