Free advertising built on what you already have: your audience.
The vision is a platform where you post your profile, browse matches by audience and niche, agree to a swap, and send through built-in email infrastructure. Any business with subscribers can use it. Zero friction and free always!
Right now, I'm matching newsletters and startups by hand. Fill out the form at stackd.tools, I find someone whose audience overlaps yours, confirm with both parties, and I handle everything from there.
Most powerful AI tools live as GitHub repos that people never use because setup is a dealbreaker. Stackd removes that entirely. Plug in your Claude API key once and toggle tools on instantly. Web monitoring, Gmail integration, calendar sync, and daily digest live now. Persistent memory with infinite context across all chats coming next as the first paid feature. The vision is a marketplace where any developer can publish a tool and any user can enable it with one click.
