Capsule CRM is a simple, easy-to-use customer relationship management tool built for small businesses, developed by Zestia Limited, a privately held software company based in Manchester, UK. Founded in 2009, Capsule focuses on straightforward contact management, sales pipelines, and light project tracking rather than the complexity of enterprise CRM suites. The product has built a loyal small-business following, consistently earning high satisfaction ratings on review platforms for ease of use, though it is intentionally lighter on advanced automation, reporting, and native two-way email sync than larger competitors. Support is offered exclusively via email, with no phone or live chat channel on any plan.
