Thank you @dens for that magical SXSW when Foursquare hit. End of an era.

Plants are trying to talk, if only we'd listen. Now, one startup says it has decoded their language. “We’re listening more than we’re speaking, but listening’s the first step,” Electric Plant CEO Justin Mast told me. techcrunch.com/2026/10/20/pl…

My past work in neuroscience has guided my foray into the fascinating field of plant signaling. Excited to relay that @ElectricPlantCo just announced Bombadil, an AI foundation model I’ve been building for the past 3 years that decodes plant electrical signals in real time.
1/ Today we’re unveiling Bombadil, @electricplantco's foundation model that reads the electrical signals of living plants and turns them into a continuous view of their physiology. Trained on 7M+ hours of plant electrical signal across 125+ species. That makes Bombadil the most species-diverse model of directly recorded electrical biosignals in existence. The animal equivalent would be one model that reads the brainwaves of blue whales, horseshoe crabs and fruit flies.

1/ Hiring your first employee is one of the biggest moments for a founder. But payroll, taxes, benefits, and compliance are far more complicated than they need to be. Now with AI we can make the pain of payroll go away. @Mercury Payroll* launches today!

"None of these systems, however, will survive the coming transition. They need to be remade entirely for the next age."

The biggest bottleneck at work is waiting on each other. Today Town is announcing its $108M Series B, co-led by Forerunner Ventures and Menlo Ventures, to fix it with multiplayer AI assistants for work. Most AI assistants are built for one person. Work doesn't happen alone. I think the moat is multiplayer. Everyone at a company gets a Townie. Townies ask each other questions, share only what their person would share, and do the work. The more a team works together, the more useful Townies get. What's the thing you're always waiting on a teammate for?

People (including me circa four years ago) have been waiting for AI tutors to eat a chunk of education, but it’s increasingly looking like AI is going to eat educational content first.

"Solo Angels" on board so far: - co-founders of two of the most legendary YC companies - CEO of unicorn model company - Former c-level at Goldman - solo founder who sold his company to a unicorn - backer of multiple decacorns This is going to be fun :)
Announcing “Solo Angels” Early access to invest in solo-founded companies Eligibility rules: you’ve made at least two early stage investments this year. Hmu if want in.

This angel has backed multiple unicorns. They just backed a Solo Founder in our current cohort building something insane in bits and atoms. I always love bringing angels in early.

The physical world is full of data we’ve never been able to put to work. Cheap sensors and increasingly capable AI are changing that. The same loop that built the internet’s biggest businesses is starting to take hold in the world around us: more deployments means more data, means better products, means more data, means more deployments. We've already placed bets in companies like @tutorintel @GrittRobotics @Sofarocean @efficient_hq @viamrobotics @IsembardGroup who are racing towards this edge. If you're an entrepreneur building in the space, especially if you're already deploying hardware into the world, you should talk to @rebeccakaden

1/ Starting today you can take actions on your @Mercury business and personal accounts right from your agent (ChatGPT/Claude/etc) via the MCP. Our MCP already let you ask questions about your accounts.* Now it can move money too (with your approval).
