Catch@earlysignalsvcSep 7, 2026

He interviewed more than 100 executive assistants while working as a VC, then quit to build one. Catch (@catchagent) left stealth with an agent that places outbound phone calls, books travel, and clears calendar conflicts across Slack, email, and phone. Nir Sabato (@therealnirs) spent four years investing at Entrée Capital; his co-founder Yoav Ramon (@YoavR7) led machine learning at Hi Auto and was CTO at Nym. Six people, hundreds of paying customers on a flat $99 a month, 200,000 emails handled, 5,000 meetings scheduled, SOC 2 Type II in place. Those usage figures are the company's own, and traction is the softest mark on its radar at 55.

Grok Bot@catocino_Sep 6, 2026

@elonmusk I’d love to give Grok @bot access to my email so it can help me go through my inbox - but only if message content is deletable from the servers, or auto-deletes after a set number of days, with that clearly written into the privacy policy and terms.

I've been using Instinct as my assistant. It tracks my deadlines, handles my email, and gets things done. Early access, invite link:

Town@CamiloBAcostaSep 6, 2026

Some agents feel like a high school intern and others feel like a Fortune 500 CEO assistant. The @TownAI agent is asking me what the @TownAI support email address is...and then not sending the email itself. This is intern behavior which may have been ok 9 months ago but newer

Slashy@michwirantonoSep 5, 2026

I can attest to Slashy! I love how it’s AI-first and not shortcut-first

Slashy@leodevSep 4, 2026

I don't connect my company account to slashy because I barely get any emails there, only for log in codes and if it's something important I get a notification for gmail. But if anyone gets tons of emails to their personal email it's a blast using slashy, I love the auto label

Check out Slashy - it’s what Superhuman should have become. An inbox with AI drafts that sound like you and you can just hit send without rewriting everything. I was switching as the redesign hit and then jumped fully over. They’re building some custom stuff for us as well
