12 best founder communities to join in 2026, sorted by what you need

The 12 at a glance

Every row was checked on the community's own pages on 11 November 2026. Member counts and other numbers a community publishes about itself are labelled as theirs.

Foundinity: if what you need is a cofounder

Communities give you people to talk to. That's worth a lot: someone who has priced a SaaS product before, a thread of honest feedback on your landing page, a Tuesday evening with founders who understand why you look tired. What they don't do is sort anyone for you. If you join a community hoping to find a cofounder, you're reading posts and going to events, then judging every person yourself.

Foundinity is built for that one job. You state what you need in a cofounder, and answer an assessment about how you work: commitment, working style, ambition, personality, goals, values, alongside your skills and interests. A multi-trait algorithm built on established psychological compatibility models ranks the people you see, so you start with compatible people rather than everyone who happens to be in the room. Each match shows where the two of you align and where you differ. Once you match, a 10-day clock starts, and you book the intro call where you matched. Your profile is visible only to compatible members.

Skills tell you who can do the job. The rest tells you who you can actually build with for years. Use the communities below for advice and company, and use Foundinity for the search. It's free to get started; Plus is $5 a week or $15 a month. More on how it works.

How we picked and checked these 12

We read the founder community lists that rank for this search today. Most are long, include tools and newsletters that aren't communities, and don't say whether anyone still posts. We wanted a shorter list you could act on this week, so each community here had to meet three tests on 11 November 2026:

1. It's open to people at the start. Someone with an idea or an early product can join or attend. 2. It's active. We looked for recent posts, upcoming events or a stated next cohort on the community's own pages. 3. Its cost is clear. If the community publishes a price, we give it. If it doesn't, we say so.

Some well-known names didn't make it:

• Elpha, a community for women in tech: its site didn't load on 11 November 2026 because its security certificate had expired.
• Female Founder Collective's 10th House: applications were closed, with a waitlist.
• WIP, a maker accountability group: members are invited by existing members, and its Pro page doesn't show a price.
• Hampton: you need more than $3 million in annual revenue, $3 million raised or a prior exit above $10 million, so it's a group for later, not for the search for a first cofounder.
• Indie Hackers' groups, including its partner-seeking group: Indie Hackers retired groups in 2026. The main forum is still active and is on the list.

The list is grouped by what you get. Numbers 1 to 4 are free online communities. Numbers 5 to 7 are in-person events. Numbers 8 to 11 are paid or selective. Number 12 is for women founders.

What do you want from a founder community?

Start with this, because the right community for feedback on a landing page is the wrong one for meeting people in your city.

Free online communities

1. Indie Hackers

What it is. A forum for people building profitable online businesses, usually without investors. Members post what they're building, what it earns and what went wrong, and ask each other for feedback.

Cost. Its sign-up page shows no fee; you join with a Google account.

How active. Very. On 11 November 2026 the newest posts were 6 hours old, and the front page had a member's "What are you building this week?" thread.

Good for. Specific questions about pricing, marketing, launches and small-business tools, and for posting your own numbers to get comments on them.

What to know. Indie Hackers retired its groups feature in 2026, including the group where members looked for partners; old group links return an error page. Partner-seeking now happens in ordinary posts, if at all.

For finding a cofounder. Posting your progress in public is a slow way to meet a cofounder, but it does work: the people who reply to your numbers already care about the same kind of business.

2. Hacker News

What it is. A discussion site for technical people, run by Y Combinator. It's mostly links and comment threads. Two parts matter to founders: Ask HN, for questions, and Show HN, for things you've made.

Cost. Free.

How active. On 11 November 2026, the monthly "Ask HN: What are you working on? (November 2026)" thread had 290 points and 1,038 comments after two days. Other Ask HN threads ranged from a handful of comments to over a hundred.

Good for. Blunt feedback from engineers on a product people can try, and a launch audience for technical products.

What to know. Show HN has strict rules: it's for "something you've made that other people can play with", not landing pages, sign-up pages, newsletters or fundraisers, and you mustn't ask friends to upvote. The general guidelines say "Please don't use HN primarily for promotion."

For finding a cofounder. The monthly "What are you working on?" thread is a good place to see who is building what and reply to people whose work you like.

3. r/startups and r/Entrepreneur

What they are. Two of Reddit's largest subreddits for founders. r/startups leans toward tech startups; r/Entrepreneur covers any kind of business.

Cost. Free.

How active. We couldn't check. Reddit blocks the tools we use to verify pages, so we haven't confirmed recent activity or the current rules ourselves.

Good for. Asking a quick question to a large audience and reading how other founders handled the same problem.

What to know. Each subreddit sets its own rules on self-promotion, and moderators remove posts that break them. Read the rules in the sidebar before you post anything about your own product.

For finding a cofounder. Read the threads where people describe their search. They're a frank record of what goes wrong.

4. Product Hunt

What it is. A site where makers launch products and people vote on them, plus a forum section where makers talk about building and launching.

Cost. Free.

How active. On 11 November 2026, the forums had threads posted 4 and 5 hours earlier, a featured post about a new launch guide from the day before, and an announced hackathon on 20 November.

Good for. Launch day, and talking to other makers about distribution, pricing and tools.

What to know. Product Hunt rebuilt its launch guide recently, saying the submission flow, scheduling rules and how points work had changed. Read it before you launch.

For finding a cofounder. Makers who launch often are easy to find and easy to judge, because their products are public.

In person: meetups and events

The Starling Bank survey of 500 people, run by Censuswide and reported in April 2026, gives a sense of how much this matters: 17% met their cofounder through a professional association or community event, 16% in a coworking space and 15% at a dedicated networking event (Startups.co.uk). Respondents could give more than one answer.

5. Startup Grind

What it is. A global network of local chapters that run talks, workshops, pitch practice and networking evenings, plus an annual conference in Silicon Valley.

Cost. Varies by event and chapter. Its homepage doesn't list a membership fee, and one event it listed this week had free tickets.

How active. On 11 November 2026 its homepage listed upcoming chapter events in Dallas, Boston, New York, Colombo, Penang, Kansas City and other cities between 11 and 17 November. The next conference is on 27 and 28 April 2027. By its own count, it has more than 300 chapters.

Good for. Meeting founders and investors in your own city on a regular evening.

What to know. Quality depends on the local organisers, so go to two or three events before you judge your chapter.

For finding a cofounder. Regular attendance matters more than any single event. You get to know people over months, which is how you learn whether someone follows through.

6. Techstars Startup Weekend

What it is. Techstars describes it as "a three-day event for aspiring founders to pitch their ideas", form teams and start a company, in "54 hours".

Cost. Set per event. The Techstars page doesn't list a price, so check the event's own registration page.

How active. On 11 November 2026, Techstars' event search listed 11 Startup Weekends and one Startup Week between 13 November and 12 December 2026, including Saarbrücken, Iowa City, Sevilla, Recife and Muscat. By Techstars' own count, more than 7,000 events have run in over 150 countries.

Good for. Working with strangers under time pressure, which shows you how people behave when it counts.

What to know. The listed dates run over three or four days, usually across a weekend, and each event has its own registration page. The people on your team matter more than the idea you pitch, because three days of work shows you more about someone than a dozen coffees.

For finding a cofounder. It's the closest thing to a short trial project with someone you've just met. If a teammate impressed you, suggest a second project.

7. Meetup and Luma

What they are. Two event platforms where local founder groups post their evenings, talks and coworking days. Meetup is organised around groups; Luma is organised around individual events and calendars.

Cost. Free to join and RSVP on both. Meetup's help centre says members on the free plan can join unlimited groups and events, but need its paid Meetup+ plan to see the list of other attendees. On Luma, hosts can charge for tickets; the basic plan is free for hosts too.

How active. It depends entirely on your city. Search each platform for "startup", "founders" and "indie hackers" plus your city, and look at how many people went to the last few events.

Good for. A regular, low-cost way to meet founders near you.

What to know. Check who runs a group and who went last time before you commit an evening. You want a group where most people are building something, not mostly selling to those who are.

For finding a cofounder. Pick one or two groups and keep going back. People remember a face they've seen four times.

Paid and selective communities

Paying gets you two things free communities can't give: vetted members and a smaller group where people answer. Whether that's worth the fee depends on your stage.

8. Founders Network

What it is. In its own words, "a global startup mentoring community for tech founders": an online forum, city chapters, events and peer mentoring. Membership is invite-only; you request an invitation, and a committee reviews applications each month.

Cost. Annual dues, based on the revenue or funding of your current or past companies. No prices are shown on its homepage.

How active. It says it runs more than 100 in-person and virtual events a year and lists 41 chapters, from San Francisco and New York to Berlin, London, Tokyo and a virtual chapter. These are its own figures.

Good for. Confidential advice from founders a step or two ahead, and introductions.

What to know. Its Launch tier is for the idea stage, pre-revenue to $10,000 in revenue, and its description includes "Find co-founders, build an MVP and validate with customers." Its fnWomen group has held virtual networking socials for women founders in the community.

For finding a cofounder. Useful if you're already committed to a tech startup and want vetted peers around you while you search.

9. MicroConf Connect

What it is. A private Slack community from MicroConf for bootstrapped and independent SaaS founders, with topic channels, live expert sessions, a talk library and a member directory.

Cost. $49 a month or $499 a year, with a 30-day refund window. You don't pay until you're approved.

How active. Applications take about five minutes and are reviewed within three business days, according to its page.

Good for. SaaS founders who want to talk about pricing, marketing and hiring with people who have run similar businesses.

What to know. It's for people building B2B SaaS at any stage, including employed people seriously working toward a launch. Investors looking for deals and service providers mainly looking for clients aren't accepted.

For finding a cofounder. Strong if you're set on bootstrapped SaaS, because everyone in the room has chosen the same model.

10. Ramen Club

What it is. A paid Slack community for founders building internet businesses with AI, such as SaaS, AI tools, marketplaces and apps. The old Indie Worldwide address now redirects to it.

Cost. £65 every three months or £170 once for lifetime access, with a 30-day money-back guarantee.

How active. Two live classes and a demo day each month, all recorded, plus introductions to other members every two weeks. It says it has more than 500 founders.

Good for. Learning with others while you build, and getting answers in Slack.

What to know. It isn't aimed at ecommerce or direct-to-consumer brands, and it recommends some product-building experience before you join.

For finding a cofounder. The fortnightly introductions put you in front of new members regularly, which helps if you're open to meeting people.

11. ODF (formerly On Deck)

What it is. The old On Deck address now redirects to ODF, which runs a founder fellowship: "an intense one-week in-person experience focused on meeting collaborators, exploring ideas, and gaining conviction", followed by an alumni community.

Cost. No fee is shown on its homepage. Check during the application.

How active. The next cohort, ODF28, starts in Q1 2027. ODF says each cohort has 80 to 100 people, more than half of them technical.

Good for. Spending a concentrated week with other people at your stage, in person.

What to know. The week takes place in San Francisco, so plan for travel and time off.

For finding a cofounder. Meeting collaborators is the stated point of the week. It's selective, and it's one week, so treat it as a strong start rather than the whole search.

For women founders

12. Women Founders Network

What it is. A US nonprofit that says it exists "to provide access to capital, visibility, and mentorship to female founders". It runs startup webinars, networking events, an annual Fast Pitch competition and a private Facebook group.

Cost. Fees aren't shown on its homepage.

How active. Its homepage doesn't list event dates; it links to an upcoming events page. It says it has more than 4,500 network members, by its own count.

Good for. Women founders who want to practise pitching and meet peers and advisers.

What to know. Its programmes centre on early-stage, women-led companies and pitching to investors.

For finding a cofounder. Its events bring together women at a similar stage, which is a good start for an introduction.

Two other options we checked: Female Founder Collective's 10th House, for women building businesses from $0 to $5 million in revenue, had applications closed with a waitlist. Founders Network's fnWomen group is open to women in Founders Network.

Free vs paid founder communities: what the money buys

The free communities on this list are larger, and they're public. That's good for feedback and launches: thousands of people see your post. It's less good for personal advice, because you rarely know who is answering.

Paid communities trade size for trust. Founders Network and MicroConf Connect both screen members. In a group where everyone has been checked, people share real numbers and real problems, and you know who you're talking to.

A simple rule: use free communities to learn and get noticed, and pay only when you have a specific problem a vetted group would help with, such as pricing a SaaS product or preparing to raise. If you don't use a paid community at least once a week, cancel it.

Can you find a cofounder in a founder community?

Yes, sometimes. In the Starling survey above, community events, coworking and networking events each accounted for 15% to 17% of answers. But they come after friends and family (34%), a former workplace (26%) and school or university (25%). Communities are where you meet people. Whether one of them could be your cofounder is a separate question, and the community won't answer it for you.

If you do meet someone promising:

1. Talk about the work before the idea. Ask how they like to work, how much time they can give and what they want in five years. Our questions to ask a potential cofounder are a good start. 2. Watch for the warning signs. Our guide to cofounder red flags covers what to look for in the first few weeks. 3. Build something small together. A few weeks on a real task shows more than months of chat.

If the search is the main reason you're joining communities, Foundinity does the sorting for you, and you can keep the communities for what they're best at.

How to get the most out of a founder community

• Give before you ask. Answer a few questions in your area before you post your own. People reply to names they recognise.
• Post specifics. "We have 40 signups and 2 paying users; here's our pricing page" gets better answers than "Any feedback on my startup?"
• Pick two, not ten. One online and one in person is enough. Spread across ten and you'll be a stranger in all of them.
• Show up regularly. At events, the second and third visit are when conversations turn into relationships.
• Respect the rules on promotion. Hacker News, Reddit and most Slack groups remove posts that read like ads.
• Write down what you learn. Advice from a thread is easy to lose. Keep a note of what you'd test.

Which founder community should you join?

If you're building alone and want feedback, start with Indie Hackers and, once you have something people can try, Show HN. If you want to meet founders in your city, find your Startup Grind chapter or a regular Meetup or Luma group, and try one Startup Weekend. If you're building bootstrapped SaaS, MicroConf Connect is the most focused paid option. If you're building with AI and want structure, look at Ramen Club. If you want vetted tech peers and can pay annual dues, apply to Founders Network. Women founders can add Women Founders Network.

And if the real goal is a cofounder, use Foundinity for that search and keep one or two communities for everything else. Our page on the best places to find a cofounder covers the other routes, and how to find a cofounder goes through the process step by step.

FAQ

What is the best founder community?

It depends on what you need. For free feedback and advice from people building small online businesses, Indie Hackers was the most active forum we checked. For vetted peers, Founders Network and MicroConf Connect screen their members. For meeting people in person, Startup Grind and local Meetup and Luma groups.

What are the best free founder communities?

Indie Hackers, Hacker News, Product Hunt's forums and the r/startups and r/Entrepreneur subreddits are free. Joining groups and RSVPing on Meetup and Luma is free too, though some events charge.

Are paid founder communities worth it?

They can be, if you'll use them. Paying gets you vetted members and smaller groups. MicroConf Connect costs $49 a month or $499 a year; Ramen Club costs £65 a quarter or £170 once; Founders Network sets annual dues by stage.

Where can I meet other founders in person?

Startup Grind chapter events, Techstars Startup Weekends and local founder groups on Meetup and Luma. Coworking spaces are another option: 16% of respondents in the Starling survey met their cofounder in one.

Can I find a cofounder in a founder community?

Some people do. In the Starling survey, 17% met their cofounder through a professional association or community event. Most met through friends and family, work or university. A community gives you people to meet; you still have to judge whether you could work together.

What is the best community for bootstrapped founders?

Indie Hackers for free, open discussion, and MicroConf Connect if you're building SaaS and want a vetted, paid group.

Is Indie Hackers still active?

Yes. On 11 November 2026 its newest posts were a few hours old. It retired its groups feature in 2026, but the main forum is busy.

What happened to On Deck?

The On Deck address now redirects to ODF, which runs a one-week, in-person founder fellowship in San Francisco. Its next cohort, ODF28, starts in Q1 2027.

Are there founder communities for women?

Women Founders Network is a nonprofit with webinars, networking events and a pitch competition. Founders Network has an fnWomen group for women in its community. Female Founder Collective's 10th House had a waitlist when we checked.

How many communities should I join?

Two is enough for most founders: one online, one in person. Being known in two places is worth more than lurking in ten.
