Esendex is a UK-based business messaging platform offering SMS, voice, and digital messaging solutions for customer communication, alerts, and operational workflows.
Esendex is a business messaging company headquartered in Nottingham, United Kingdom that has provided SMS and voice messaging services to businesses since 2000, serving thousands of UK and European organizations across healthcare, local government, financial services, utilities, and retail with business messaging capabilities for appointment reminders, payment alerts, service notifications, staff communication, and customer engagement campaigns. The company's longevity in the UK business SMS market — over two decades of continuous operation — reflects a stable focus on the mid-market and enterprise business messaging segment rather than the developer API market, with a product emphasis on usability for non-technical users and dedicated account management relationships rather than self-serve API-first onboarding.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
