Hustle

Hustle is an employee-owned text, video, and voice communications platform that lets organizations engage audiences at scale from a single interface. It combines broadcast texting, peer-to-peer 1:1 conversational texting, video messaging (Hustle Clips, Personalized Clips, and Hustle Stories), and an outbound dialer, and is used by nonprofits, educational institutions, commercial businesses, political campaigns, government agencies, and labor unions to reach people over the channels they already use. The Hustle Public API (v3) exposes a RESTful, OAuth2 client-credentials interface for managing agents, groups, leads, custom fields, tags, organizations, CRM integrations, message delivery status, and webhook registrations. Hustle was added to the API Evangelist network as a portfolio company of GV and Insight Partners and enriched from its public developer surface.

Hustle publishes 10 APIs on the APIs.io network, including Access Token API, Agents API, Custom Fields API, and 7 more. Tagged areas include Company, Enterprise, Messaging, SMS, and Peer-to-Peer Texting.

The Hustle catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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.
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/. This rating is computed from github.com/api-evangelist/hustle: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
