51Talk

51Talk is an online English-language education platform that connects learners with certified teachers through one-on-one live video lessons. Founded in 2011 and listed on the NYSE, the company operates across 90+ countries with a large base of accredited teachers, delivering a structured curriculum and ready-made teaching materials for both children and adult learners. Following a strategic shift, 51Talk focuses on international markets outside mainland China, including the Philippines and the broader Southeast Asia region, and recruits teachers globally. It is a consumer education company backed by DCM Ventures; as of this profile it publishes no public developer API, SDK, or documentation surface, so this repo carries only identity and domain-security signals.

51Talk is profiled on the APIs.io network. Tagged areas include Company, Consumer, Education, EdTech, and Online Learning.

Regulatory Posture applies to this provider. Its tags matched the Education & Research 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/.
