Limbo

Limbo is a direct-to-consumer digital weight-loss and metabolic-health program operated by Vitals in View, Inc., with subsidiaries in the UK (company no. 15047668) and Ireland (company no. 725671). Members wear a body-worn "energy sensor" that reads metabolic signals, and a companion app turns those readings into personalized, nudge-based guidance intended to change eating habits without calorie counting. The company is Seedcamp-backed, raised a seed round in September 2022, and is mid-rebrand from Limbo (limborevolution.com) to Viv (viv.co), with the marketing site now served from content.viv.co. Limbo publishes no public API, developer portal, SDK, or /.well-known/ discovery surface; this profile captures its identity and probed security posture only.

Limbo is profiled on the APIs.io network. Tagged areas include Company, Health, Digital Health, Metabolic Health, and Weight Loss.

Limbo’s developer surface includes engineering blog, signup flow, YouTube channel, and 8 more developer resources.
