The small team after launch
Two to five people with first users. Usually stuck on: turning users into paying customers, choosing what to focus on, and money to keep going.
Small teams, big plans
A community of early-stage founders. Grow your network, validate your product and find your first users. Meet like-minded founders to share both your wins and your failures with. Joining is free.
For founders
Founders of startups at pre-seed and seed, just before launch or soon after it.
Two to five people with first users. Usually stuck on: turning users into paying customers, choosing what to focus on, and money to keep going.
Builds fast, often with AI. Usually stuck on: talking to customers, sales, and saying what the product does in one sentence.
Knows the market and the problem well. Usually stuck on: building a first version, finding a co-founder, and checking if people would pay.
Built something people like, in the evenings. Usually stuck on: where to launch, how to price, and whether to go all in.

Connections
Tell us about yourself and answer a few questions. Our AI host picks the people most useful for you to meet: founders solving the same problem as you, or people who could help you solve yours.
Launching something? Share it with the community. Members who have the time try it and tell you what works.
Regular networking calls where you share links to your projects and your LinkedIn, Instagram or X, and swap them with other founders.
Share your project and its links in the channels made for it, like #share-your-project, and show it on calls when someone asks. See the house rules.
Look inside
The community lives in Mantle Chat. A channel for every need, and calls with AI notes in the same place. None of it is set in stone: we'll see what works and what doesn't, and shape the community together so it suits all of us.
Builders Club
You don't have to be in every space: tell us which ones fit you, and we add you only there. In each channel, choose what reaches you: every message, only mentions, or nothing. Need a quiet day? Mute a channel for an hour, or until tomorrow morning.
Calendar
Regular meetups every week, and sessions with guest experts. Come to the ones you like, as often as you like. Once you're in, join any event yourself, or pick your topics and we'll let you know when something on them is coming up.
Regular meetups · what the community gives you
A meetup goes ahead when at least two members sign up. We find a time that suits you.
Sessions with guest experts
The exact topic of each expert session is set later, together with the expert. Dates come with it.
Coming soon
Soon you'll be able to suggest your own topics inside the community and pick the ones you'd like to join. For the most wanted ones, we find guests who can cover them well, and put them on the calendar.
Something you're stuck on, or something you want to learn from people who've done it.
Mark the topics you'd join. No scores, no pressure: it just tells us what to plan.
The most wanted topics go on the calendar, with an expert or a member who knows the subject well.
Build it with us
Builders Club is free and run by founders, for founders. Want to do more than join the calls? Write to us and say which part you'd like.
Take one part for three months: Build together, Pitch swap or a table on your topic, about an hour or two a week. Your name and project go on this page, and founders who need what you do meet you first.
Solved something other founders are stuck on, like a first sale, a grant or a launch? Run one short session on it, or pitch at Pitch Night. Build with AI? You could also be in AI at Work, our expert interviews on Shift.
Know something founders need, build a tool for startups or run events for founders? See the page for partners.
Beyond the calls
Joining is free. Feedback from other founders works from the first day. Ways to earn come as the community grows.
Share what you build and ask who would try it. Founders who have the time test it and tell you honestly what works and what doesn't.
#share-your-project#share-your-icp
Free or paid, online or in person: a workshop, a dinner or a trip for the community. For paid ones, you set the price and get paid. We help spread the word.
Hosts who start with us will be the first to run their own communities on Mantle Chat, free or paid, as they choose.
