The best product management community depends on what you need from it, and for most people reading this, that is a PM job. So start with AllthingsPM for the part no chat group can give you: scored mock interviews built from any job description, and 4,122 real interview questions from 260 companies, each on its own page. Then join one or two free communities for people: Product School's Slack (over 100,000 members, per its own page), Mind the Product's Slack (60,000+), r/ProductManagement on Reddit (about 282,000 members) and a Discord such as GetToPM or Product Map.
AllthingsPM is an AI PM course and PM interview prep platform. Community sizes below come from each community's own page or a public subreddit tracker, checked 29 September 2026.

Sizes checked 29 September 2026 on each community's own page; the Reddit figure is from GummySearch. Communities grow and shrink, so treat these as a snapshot.
The chart shows the gap plainly. Every community gives you answers from other people. Only AllthingsPM gives you a scored rep on a real question, which is what moves your interview performance.
What is AllthingsPM, and why is it ranked first for PMs?
AllthingsPM is not a chat group. It is the practice layer every community member ends up needing: someone in Slack tells you to "practice product sense out loud," and AllthingsPM is where you do it.
Paste any job description into the JD mock interview and the AI interviewer builds the interview around that company, role and level, asks follow-ups, and scores your answer. You can type or speak. If you want a specific question type instead, the mock interview lets you drill product sense, execution, metrics or behavioral rounds.
Around the mocks sits the material that PM communities keep asking for in threads:
- The question bank holds 4,122 real PM interview questions from 260 companies, each with its own page and answer guide, and a page per company such as Google.
- The jobs catalog lists 116 live PM job descriptions from 18 AI companies, each with a ready mock, like this Anthropic growth PM role.
- The AI PM course was built from 604 real PM job postings, with a full chapter on the AI PM interview loop.
- Resume review against a JD, plus 455 PM portfolios to study how working PMs show their work.
The free tier includes one JD mock and one resume review a day. Pro is $20 a month or $120 a year.
Which Slack communities are best for product managers?
Slack is where most established PM communities live. The two big free ones are run by education and events companies, which is why they are well moderated and full of events.
Product School Slack
Product School calls its workspace "the #1 Slack Community for Product Managers" and states over 100,000 members [1]. Its page lists weekly Ask Me Anything sessions with product leaders, 26 local channels by region, channels for resume reviews and job postings, and more than 20,000 answered PM questions [1]. It is free to join.
Its strength is scale and the daily job posts. The trade off with any group this size is noise: your question competes with hundreds of others.
Mind the Product Slack
Mind the Product's Slack states 60,000+ product managers and is free [2]. Channels include #advice, #careers, #feedback and #producttank, the last tied to its ProductTank meetups [2]. It has written house rules focused on civility and active participation, which keeps the tone useful.
It is the best Slack for experienced PMs who want to debate real work problems rather than interview tactics.
Friends of Lenny's Newsletter
This Slack is open only to paid subscribers of Lenny's Newsletter [3]. The community page lists discussions about product, growth and career, mentorship programs, book clubs, live AMAs, hands-on workshops, and monthly meetups on five continents [3]. The paywall keeps the signal high.
How AllthingsPM does this: Slack threads tell you what an interviewer might ask; AllthingsPM lets you answer it and get scored. When a job post lands in a Slack channel, paste it into the JD mock and you have a practice interview for that exact role in a minute. If the post names a company we cover, open its company page to see the questions it has asked before.
Is Reddit a good product management community?
Yes, for candid answers. r/ProductManagement has about 282,000 members, growing by roughly 55,000 a year, according to GummySearch [4]. The most common posts are advice requests, career questions and debates about how AI is changing the role [4].
Reddit's advantage is anonymity. People say what they earn, why they were rejected, and what their manager actually expects, which is rare on LinkedIn or a named Slack. If you are in India, the smaller r/ProductManagement_IN (about 12,000 members, per the same tracker) focuses on the local market [4].
The weakness is structure. Threads are hard to search, the best answers are buried, and advice is often contradictory. You read ten opinions on how to answer "How would you improve Spotify?" and still have not said an answer out loud.
How AllthingsPM does this: take the question from the thread, find it in the question bank, read the answer guide, then run it as a mock interview. You turn a Reddit argument into a scored rep. Our guide to free PM mock interview options lists more ways to practice at no cost.
Which Discord servers are best for product managers?
Discord PM communities are smaller and more informal than Slack, which suits people breaking into the field. Directory sites list only a handful of PM Discords, and most are free [5].
GetToPM Discord
GetToPM runs a free Discord aimed at people transitioning into PM, especially from non-traditional backgrounds [6]. It allows anonymous participation so members can ask "silly questions," and it matches members for peer mock interviews or lets them watch live sessions [6]. It is one of the few communities built around interview prep.
Product Map Discord
Product Map states 15,000+ active members on its Discord and 50+ top contributors, with 60+ curated product topics and collaborative guides [7]. Joining the Discord is free; paid tiers unlock more resources [7]. It is a good pick if you want a global, friendly place to find peers.
How AllthingsPM does this: peer mocks are valuable, but they depend on a partner showing up and knowing how to score you. AllthingsPM gives you a mock any hour, with consistent scoring, so you arrive at a peer session already sharp. See our comparison of peer mock interview communities for PMs for how to combine the two.
What about communities for specific groups of PMs?
Some communities serve a narrower audience well.
Women In Product describes itself as a one-stop shop for advancing a career in product, with an annual conference, virtual and local meetups, book clubs, a podcast called Product Rising, local chapters and a dedicated community platform [8]. It also runs "The Human Edge," an eight-week leadership cohort for mid-career women [8].
Mind the Product's ProductTank meetups extend its Slack into in-person events in many cities [2], and Lenny's community runs city meetups for paid members [3]. If you learn better in a room, these are worth the trip.
How AllthingsPM does this: meetups and chapters give you mentors; AllthingsPM gives you the reps a mentor will tell you to do. Our book summaries and podcast summaries also cover the frameworks those meetups discuss, so you can catch up before you go.
How do you get the most out of a product management community?
Joining is easy. Getting value is a habit. A simple routine:
- Pick one community, not five. Notifications from five Slacks become noise. Choose one Slack or Discord plus Reddit for reading.
- Introduce yourself with a specific ask. "Career switcher from analytics, targeting AI PM roles at Series B startups" gets better replies than "Hi all."
- Give before you ask. Answer one question a week in an area you know. People remember helpful names when referrals come up.
- Use job channels as a practice queue. Every posting in Product School's job channel or Mind the Product's #careers is a free mock waiting to happen in the JD mock.
- Close the loop with scored practice. After a thread teaches you a framework, answer a real question on AllthingsPM and check your score. Advice you never rehearse does not show up in an interview.
How AllthingsPM does this: the routine above works because AllthingsPM handles steps 4 and 5 without needing anyone else online. Pair it with resume review against a JD before you ask a community member for a referral, so your resume matches the role you are asking about.
Why AllthingsPM is the better choice for a product management community
A product management community answers the question "who can I talk to?" AllthingsPM answers the harder one: "how do I get better, fast, at the interview in front of me?"
Communities do some things well, and we would not pretend otherwise. Product School and Mind the Product have huge free Slacks with job posts and AMAs. Lenny's community has high signal for paid subscribers. Reddit gives honest, anonymous answers, and GetToPM offers peer mocks for career switchers.
But none of them scores your answers, builds an interview from the job description you care about, or gives you 4,122 real questions with one page and answer guide each. That is what AllthingsPM does, alongside 116 live AI PM job descriptions with a mock each, an AI PM course built from 604 real postings, resume review against a JD, 111 book summaries and 455 PM portfolios, all in one account.
It also costs less than most paid communities and coaching: free for one JD mock a day, and $20 a month for unlimited mocks. Use a free community for people and morale. Use AllthingsPM for the reps that convert into offers.
If you only have an hour this week, spend it on one scored mock interview rather than scrolling a channel. For more options, see our ranking of the best PM mock interview platforms.
