Executive Summary

Loon was an Alphabet-backed moonshot that built and operated stratospheric balloon networks to deliver LTE internet to rural and underserved populations — a genuinely important problem and a technically impressive solution. The traction claims are real and verified: a commercial launch in Kenya in July 2020, emergency connectivity for hundreds of thousands in Puerto Rico and Peru, and a world-record 312-day balloon flight. However, there is one overriding fact that dominates this entire report: **Loon is a defunct company**. Alphabet officially shut it down in January 2021, with CEO Alastair Westgarth explicitly citing an inability to reduce costs to a sustainable level. Evaluating Loon as an active investment opportunity is not applicable — this report is best read as a post-mortem on a failed but instructive deep-tech venture, with lessons for anyone considering the stratospheric connectivity space.
