Terra API Tech Stack

Health data integration API for wearables and AI applications

Software Development London 11–50 employees Founded 2021 Privately Held

Terra API operates a health-data integration layer targeting developers and AI agents, built on AWS + GCP with Python, Swift, and Kotlin SDKs. The tech stack reflects dual demands: mobile-first device connectivity (Flutter, React Native, Swift, Kotlin) and backend data engineering (Python, Go, Graph API adoption). Pain-point clustering—normalizing heterogeneous health streams, ingesting at scale, extracting predictive signals—reveals the core friction: wearable ecosystems are fragmented, and real-time biometric normalization remains computationally expensive.

About Terra API

Terra API provides wearable data interoperability for developers building health and fitness applications. The product surface spans three layers: lightweight SDKs for mobile device data access (iOS/Android), real-time streaming pipelines for continuous biometric ingest, and higher-order analytics (predictive modeling, dynamic playbooks, research briefs) that extract actionable insights from multi-source health data. Founded in 2021 and based in London with ~40 employees, the company is engineering-heavy (5 engineers, 1 data scientist, 1 researcher) and actively scaling infrastructure to support millions of users. Hiring has decelerated in the past month, with most open roles at mid-level.
