The company provides an integrated software solution for corporate carbon accounting, ESG reporting, and net-zero planning, serving over 200 companies predominantly in the DACH region and broader Europe. Plan A was one of the early European entrants in the corporate sustainability software market.\n\nThe platform covers the full ESG lifecycle, from data collection and carbon footprint calculation to materiality assessments, ESG scoring, and regulatory report generation. Plan A supports multiple reporting frameworks including GHG Protocol, CDP, GRI, and the EU taxonomy. Its module for double materiality assessment is particularly relevant for companies navigating the CSRD requirements that mandate identifying both financial and impact materiality.\n\nPlan A targets mid-size to large enterprises in Europe that need a comprehensive ESG platform rather than a point solution. It competes with Greenly, Normative, and Sweep in the European market. The company differentiates through its breadth of ESG coverage beyond just carbon, its consultancy network of sustainability experts, and its early mover advantage in the EU regulatory compliance space.
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.
