    HERO▲382

    Hey HN! I’m Kevin, the founder of HERO. Thank you so much for checking out our launch today. We built HERO because serious work deserves better tools than paper-based documents built with word processors built in the 90s. If your team works on contracts, policies, SOPs, technical specs, or any structured, formal documents, you know the pain: - information buried across multiple files, sections, exhibits, etc. - repeated copy-pasting - outdated definitions - impossible cross-referencing - version chaos - hours wasted searching for the right clause, number, term, or page HERO solves this by…

    Teamhub.com▲237

    Hey HN, We've just launched our team collaboration platform where we're bringing together all the important tools under one app. We've been frustrated in the past with tools which had a huge disconnect between projects and chat. It always inevitably leads to teams using external chat apps for "project management" and then abandoning the main tools altogether. We're creating tools we hope teams will stick with.
