Case Study: Voyager Labs achieves over 35% EC2 cost savings and hands‑free RI management with Zesty

Voyager Labs saves more than 35% on their EC2 costs, hands-free

Voyager Labs, a leader in AI-driven human behavior analytics, faced rapidly rising AWS costs as hundreds of isolated customer environments left them running thousands of On‑Demand EC2 instances. Manual forecasting and purchasing of Reserved Instances (RIs) was time-consuming and error-prone due to RI complexities (Standard/Convertible, Cross‑AZ, Tenancy, Upfront), so Voyager Labs engaged Zesty for automatic lifecycle management of RIs to streamline cost optimization.

Zesty deployed its real‑time AI engine and commitment manager to continuously buy and sell RIs (with guaranteed buy‑back for over‑provisioning), giving Voyager Labs instant visibility and hands‑free optimization. As a result of Zesty’s solution, Voyager Labs cut EC2 costs by more than 35%—saving over $50K a month—and eliminated manual RI forecasting, freeing engineers to focus on product development.
