Overview
About Cosy
Alright, community heroes, listen up. You're out here trying to build an actual vibe in your Slack workspace, but between the endless "hellos," the awkward intros, and trying to figure out who knows what, you're burning the candle at both ends. Enter Cosy. Think of it as your ultimate Slack sidekick, a native bot designed to automate all the tedious stuff so you can focus on the magic. Built specifically for community managers, Cosy turns your standard Slack into a buzzing, connected community hub without you needing to be online 24/7. It handles the grunt work: automating personalized welcome DMs for new joiners, making cool intros between members, and even surfacing the most fire content so nothing gets lost. It gives your community a searchable directory right inside Slack, so people can actually find each other. The best part? It works while you sleep. Whether you're running a tight-knit crew of 50 or a massive server with hundreds, Cosy is here to take the manual labor off your plate, boost engagement on autopilot, and finally give you back those precious hours every week. It's like having a super-organized, never-tired co-manager that lives in your Slack.
About SureThing.io
SureThing is an autonomous AI agent that remembers who you are and works on your behalf 24/7. Unlike AI chatbots that wait for instructions, SureThing operates proactively: it monitors your inbox, drafts replies in your voice, manages your schedule, tracks ongoing projects, and takes action across connected apps while you're focused elsewhere.
Its persistent memory sets it apart — SureThing remembers your preferences, your patterns, your contacts, and your goals across every session. It doesn't lose context, doesn't repeat mistakes, and adapts continuously to how you work.
SureThing is built for reliability over demos. SOC 2 certified and Google CASA Tier 2 compliant, it is designed for users who need an agent they can actually trust with real work — not one that breaks the moment it leaves the slide deck.
Early adopters include a technical director who contributed code to OpenClaw and calls SureThing "the Mac of AI agents," and solo founders executing full go-to-market launches alone.
