  Hey HN, I am Leo Jiang, founder of Gro. I built this to solve the problem of fragmented sales stacks where teams waste hours between lead databases and outreach tools. Gro is a unified AI sales agent that combines a 1b+ contact database with AI propensity scoring and automated outreach across Email and LinkedIn. By putting prospecting and engagement into one workspace, we eliminate manual data hunting so sales reps can focus on closing deals. I would love your thoughts on our approach to automated B2B growth.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
