About
Wynter is a B2B message testing platform that helps product marketers, demand generation teams, and founders validate whether their messaging resonates with their specific target audience before publishing it. The platform maintains panels of verified B2B professionals segmented by job title, seniority, company size, and industry, allowing teams to get feedback on landing page copy, ad headlines, email subject lines, and value propositions from the exact personas they are trying to reach. This specificity is what differentiates Wynter from general consumer survey panels where respondents may not represent the B2B buyer personas relevant to enterprise software.
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.
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.
