About

Postmark is a transactional email delivery service founded in 2009 by Wildbit and subsequently acquired by ActiveCampaign, providing developers and product teams with a dedicated sending infrastructure purpose-built for the reliability and inbox delivery performance requirements of application-generated transactional email — password resets, account confirmations, purchase receipts, invoice delivery, and notification emails where delivery failure or delays directly impact the user experience and can prevent customers from completing essential account actions. Postmark's founding philosophy was that transactional email deserved a dedicated sending infrastructure and reputation that was never shared with bulk marketing email — a deliberate architectural decision that has defined its positioning in the developer email infrastructure market.

About

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.
