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 Software-as-a-Service.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tello: open an issue to ask a question, or submit a pull request to add artifacts.
