Agree, a lot of us have great ideas and projects but no capital or contacts for marketing. Wondering if theres a product out there that can completely automate the marketing aspect of it.
Anyway, to answer your question: Autonomous Multi-Channel Agents (e.g., Emma, AgentsVerse) are close to what you asked for. They don't just draft posts; they identify "just-funded" leads, scrape LinkedIn, and run autonomous ad optimizations.
Edited: Just to clarify, I mentioned Emma and AgentsVerse as examples of where marketing automation is heading, not tools I've personally vetted for the specific capabilities listed.
