Mindstrong

Mindstrong (Mindstrong Health) was a digital mental health company backed by General Catalyst that combined a virtual behavioral-health care team with a research program in "digital biomarkers" — passively measuring cognition and mood from smartphone interaction patterns. The company wound down its consumer care operations around 2023. It never published a public developer API, documentation portal, or API reference; its primary domains no longer serve a live site. The one first-party software artifact located is a Python research library (digital biomarker model fitting) published to PyPI by the company's data science team. This profile is retained in the API Evangelist network as an enriched company record with no public API surface.

Mindstrong is profiled on the APIs.io network. Tagged areas include Company, Mental Health, Digital Health, Behavioral Health, and Digital Biomarkers.

Regulatory Posture applies to this provider. Its tags matched the Health 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/mindstrong: open an issue to ask a question, or submit a pull request to add artifacts.
