Starnus is an AI-powered outbound sales automation platform built for founders, startups, and B2B sales teams who want to automate prospecting and outreach without juggling multiple expensive tools. With Starnus, you can define your ideal customer profile (ICP) using simple natural language prompts, discover lookalike prospects from millions of verified business records, enrich leads with business and contact data including emails, phone numbers, company size, industry, and revenue, generate personalized multi-channel outreach across email and LinkedIn, automate follow-up sequences based on engagement signals, and track opens, replies, and conversions from a single dashboard. Starnus replaces the need for separate tools for prospecting, data enrichment, email sequencing, and campaign analytics.

Built for solo founders doing outbound for the first time, small B2B teams scaling pipeline without adding headcount, and agencies managing outreach for multiple clients. Starnus integrates with HubSpot, Gmail, Google Sheets, and Slack. Start with a free 14-day trial โ€” no credit card required.

  • The most popular AI coding skills right now
    GStack is Garry Tan's Claude Code setup, and at nearly 110,000 stars it is one of the most popular skill collections out there. Instead of one mode that handles everything, it gives the agent distinct roles, each behind its own slash command. It has product vision, designer, engineering manager, release manager, doc engineer, QA, and post-launch retrospective. It is the same genre as Superpowers, a full workflow,... - Source: dev.to / 23 days ago
  • GStack: Turn Claude Code Into a Full Engineering Team
    That is the design. And it is why GStack โ€” Garry Tan's open-source Claude Code skill setup โ€” has accumulated 82,700 stars and 12,000 forks on GitHub since its March 2026 launch. - Source: dev.to / 2 months ago
  • The YC President Endorsed an AI Memory System With Fake Benchmarks. He Also Shipped His Own. We Read the Code.
    This is not the first time. Tan's previous project, gstack, has amassed over 69,000 GitHub stars. Developer Mo Bitar described it as "a bunch of prompts in a folder." Another founder noted that without the YC title, it would not have made Product Hunt. A developer who examined Tan's AI-generated website code found 78,400 lines including empty CSS files, duplicate assets, and test files shipped to production. - Source: dev.to / 3 months ago
  • CFFBRW went from drag-and-drop to "hey AI, just deploy this for me"
    And I believe any builder should use Gstack from Garry Tan. Old news I know, but for people who live under a rock like I do. - Source: dev.to / 3 months ago
