top founder networks and communities, compared honestly

who each one is for, how you get in, what it costs, and how to pick one for your stage

start here

You quit your job, or you leave school, and you start a company. You land your first customer, you lose your second, and at 1am it's just you and the decision about whether to let someone go. And then what? A friend texts "so how's the startup?" and you write "good". Your partner is patient, your parents are proud, and none of them know what this is like. What you want now is other founders: people who have been through the same things, so you don't have to explain everything from the start. But finding the right ones is hard. One group wants $3M in revenue before it will talk to you, one costs more than your first hire, and one is a Slack that went quiet in spring. Here is the whole map: who each one is for, what it costs as of October 2026, and where the catch is.

start with what you need, not with the name

People talk about founder networking as if it were one activity. It's five, and every network here is good at one or two and poor at the rest. Decide which you're short of before you apply or pay.

• Peer support. A few people at your stage you can tell the truth to. The paid forum groups exist for this; little else does it well.
• Intros. One specific buyer, investor or hire. Program alumni networks and the intro tools are strongest here.
• Learning. How someone got through what you're stuck on. The free communities, if you ask a specific question.
• Cofounders and hires. The matching tools, Hacker News, and the programs that take people before they have a team.
• Investors. Program networks first, then the intro tools, then events.

Kathleen Lucente put one more distinction well in Fast Company's Executive Board this October: "A network is a list of people who take your call. A community sends you things unprompted." Everything below starts as the first kind, and becomes the second only if you give first.

free founder communities: ambient, reddit, indie hackers, hacker news and the slack groups

These cost nothing. ambient checks that you're a founder before you're in; the others let anyone in, which makes them the right place for a specific question and the wrong place for anything that looks like promotion.

ambient

ambient is a private society of founders who build each other. Every founder hits a wall outside their skill, the engineer stuck on sales copy, and the usual advice is to beg for a warm intro, sit through a coffee chat, or pay someone. ambient's answer is founders doing an hour of real work for each other, and you get in by helping, not by paying or pitching. It's free, for verified founders, and it all happens by text. You bring one problem at a time and get a warm intro from a founder who knows the person, or up to an hour of written help on your draft, and you give the same kind of help to others. The trade-off is no events and no group chat.

reddit for founders: r/startups, r/Entrepreneur and r/SaaS

Reddit is the biggest free startup community, and it's good at one thing: questions and answers with strangers who have no reason to flatter you. r/startups, around two million members, is the general room. r/Entrepreneur is more than twice that size and broader, with more small businesses than startups. r/SaaS, over 600,000 members, is where software founders compare pricing, churn and tooling. All three ban self-promotion and mean it, so you don't go to Reddit to be found. You go to ask one specific question, get five honest answers, and give a few back.

indie hackers

Indie Hackers is the community for people building profitable software without raising money. People post revenue numbers, pricing experiments and what failed, which is rare in public. In 2026 the groups feature was retired, so it's one forum again, and a paid IH+ tier ($198 a year) lets you post from day one. If you're bootstrapping a SaaS, it's still the best free room online. If you're raising a seed round, you'll feel out of place.

hacker news

Hacker News isn't a community you join so much as a place you read. Show HN is for "something you've made that other people can play with", not a landing page, and a good one gets a few hundred technical people trying your product. The monthly "Ask HN: Who is hiring?" thread is still a good free place to find an early engineer. Don't expect warmth. Do expect the most useful critical comment you'll get all month.

the slack and discord groups that are still alive in 2026

Here's the uncomfortable part of every list of the best startup communities on Slack: most of the groups on it are quiet, paid, or gone. Buildspace shut down, Small Bets closed to new members, Launch House became a fund. The ones still running well are small, niche and gated: MicroConf Connect for bootstrapped SaaS founders ($499 a year), WIP for makers who ship in public ($199 a year), Ramen Club for founders building with AI (£25 a month), and the Slack for paid Lenny's Newsletter subscribers. The one free, active founder Discord we could confirm is Furlough. Before joining any, check the dates on the last ten messages in the busiest channel; if they're spread over weeks, leave.

program networks: the ones you can't just join

A lot of what people mean by "founder network" is really an alumni network, and you can't join one on its own: you get in by being accepted into the program, which usually means giving up equity, moving for a few months, or both.

• Y Combinator. Three months, no fees. $125,000 for 7%, plus $375,000 on an uncapped SAFE that converts later. YC calls its alumni community "probably the most powerful community in the startup world": more than 7,000 founders, a private platform called Bookface, and, by YC's own account, companies often get their first 40 to 50 paying customers from it.
• Techstars. Also three months, in many cities: $220,000 for 5% plus an uncapped SAFE, no fee. More than 11,000 founders since 2007, strongest in its own cities.
• South Park Commons. For technologists between things, before there's a company: six months in San Francisco, New York or Bangalore, no fee, no equity, next to about 175 other members.
• Antler and Entrepreneur First. Both take individuals before there's an idea and help you find a cofounder first. Antler's US residency is up to three months in New York, San Francisco or Austin, no fee, with an initial investment Antler puts at $500,000 to $1M. EF is 12 weeks in London or Bangalore, then 12 in San Francisco, with a living grant and up to $250,000 once a company forms.
• Founder Institute. The one you pay to attend: an entrance fee by chapter ($1,599 in New York) plus a 2.5% warrant, for ten sessions and a Funding Day in 200-plus cities. FI says roughly 30% of applicants are admitted.

paid, vetted peer groups: ypo, eo, vistage, hampton, chief and founders network

These are what people mean by "CEO peer group" or "founder peer group": eight to sixteen people who run companies, meeting monthly, in confidence, usually with a trained moderator, and most have a revenue bar. In Startup Snapshot's 2023 survey of founders, The Untold Toll, 72% said the journey had affected their mental health, and 81% said they don't openly share their stress and fears, which is what a confidential room of peers is for. They're poor at "I need customers": nearly all ban selling to other members.

• YPO. The global one, with over 38,000 members: under 45, roughly $16M+ in revenue, and 50 full-time employees or 15 with a $2.75M payroll. Dues are $4,790 a year plus a $4,790 initiation fee, plus chapter dues.
• EO. Nearly 20,000 members in 220-plus chapters. You need $1M+ in revenue, or $2M+ raised if you're venture-backed. Your chapter interviews you and places you in a Forum, a confidential monthly group of six to ten with a trained peer moderator. Dues are $2,630 a year plus a $3,500 initiation fee, plus chapter dues.
• EO Accelerator. For the stage before EO: $250,000 to $999,999 in revenue, $1,750 a year plus local fees, four learning days a year plus a monthly accountability group, and you graduate into EO at $1M.
• Vistage. The biggest, with over 45,000 members. The Chief Executive program needs $5M+ in revenue: a monthly full day with 12 to 16 CEOs from non-competing companies, plus a monthly one-to-one with your Chair, a former CEO. Vistage doesn't publish prices.
• Hampton. For founders and CEOs with $3M+ in revenue or raised, or a $10M+ exit, in one of its 18 chapter cities: a monthly three-hour meeting with eight other founders and a professional facilitator, plus a City Lead who makes intros. It costs $15,000 a year plus a $2,500 joining fee as of November 2026, and there's a strict no-solicitation policy. For a venture-backed founder past $3M searching for a private network for founders, this is the closest fit.
• Chief. For women in senior leadership, including founders, with 15-plus years of leadership experience and either a founder role at a mid-market or larger company or $2M+ in revenue or funding: a Core Group of peers, coaching and clubhouses in four cities, on a 12-month commitment. The price isn't on its web pages, and it isn't for people looking to solicit business.
• Founders Network. The accessible paid option for early-stage tech founders: three tiers by stage, from $899 a year at idea stage to $2,999 past $1M in revenue. A member nominates you, a committee of members reviews applications monthly, and most of it runs online: a forum of 600-plus founders, monthly roundtables, chapter meetups. If you've been searching for a Founders Network review, the fair summary is small, online-first, genuinely founders-only and inexpensive.

intro and matching tools that work like networks

These aren't communities, but founders use them for the same jobs.

• Boardy. An AI that makes introductions by text, iMessage, WhatsApp or email. You tell it who you need and it introduces you to someone it has already talked to, once both of you say yes. It's free, and by its own count had made over 279,000 introductions as of 18 October 2026. Its founder told EO Magazine (a San Francisco startup publication, not the peer group) in September 2026 that about 20% turn into a meeting both people find useful. The catches, from its own FAQ: a daily cap on intros, a cap on intros to potential customers, and no guarantees.
• Happenstance. Connects your Gmail, calendar, LinkedIn and X, then shows who in your own network can make the intro you need. Free with usage limits; Pro is $24 a month billed yearly. It finds the paths you already have and can't add new ones.
• Cosign. New in late September 2026 from Erik Torenberg: a curated professional network for the startup world, built on endorsements rather than self-written profiles. You join by being cosigned or by applying; it's too new to judge, and its site doesn't state a price.
• CoffeeSpace. A cofounder-matching app: profiles, mutual interest, then chat. Free for founders, with 30,000-plus users by its own count; YC's Co-Founder Matching does the same job, free, and is larger.

local: founder dinners, meetups and your city's luma calendar

The best founder conversations still happen in person, in rooms of ten. In most US cities the calendar now lives on Luma, which lists events in 32 cities. 1 Million Cups, run by the Kauffman Foundation, is the most reliable free founder room outside the big hubs: every Wednesday morning in more than 100 US communities, and every session ends with "What can we, as a community, do to help you?"

Chris Heivly of Techstars, who has run plenty of meetups, warns that most are built for people raising money, and if you're not raising, you walk in and quietly realise the room wasn't designed for you. Founder dinners are the better version: eight to ten founders, one table, no pitching. The best are invite-only, hosted by a founder or a fund, and you find them by asking founders you know which ones they go to.

how to choose

By cost. Free: ambient, Reddit, Indie Hackers, Hacker News, Startup School, Co-Founder Matching, Boardy, Happenstance's free tier and 1 Million Cups. Under $3,000 a year before local fees: Founders Network and EO Accelerator. More once you add initiation fees and chapter dues: EO and YPO. $15,000 a year plus a $2,500 joining fee: Hampton. Not published: Vistage and Chief.

By time. ambient is about an hour when another founder needs you, and a text when you need one. A forum group is a half-day a month plus a retreat or two, and only works if you never skip. Reddit is fifteen minutes while the coffee brews.
