DataTalks.Club is the largest online community for data and AI practitioners, with almost 100,000 Slack members and more than 130,000 newsletter subscribers. Since September 2020 we’ve produced free courses, a weekly newsletter, a podcast, workshops, and in-person meetups. Everything is free for the community, and it stays that way because companies sponsor it.
Sponsors keep this community free
I’m Alexey Grigorev, and I’ve been running DataTalks.Club since I founded it in September 2020.
Companies regularly write to ask how we might work together, and I usually reply with a long, detailed email walking through the options. So I’ve written that email once and put it here, where you can read it on your own time and work out whether we’re a good fit before we even get on a call.
Our courses have no tuition, the newsletter costs nothing to subscribe to, and the podcast has no paywall. That’s by design, because most of our members are learning on their own time, often outside of work hours, and putting up a paywall would shut out exactly the people we built this for. But a community of this size takes real work to run. We produce course content, host weekly events, moderate tens of thousands of Slack conversations, edit a podcast, and send a newsletter every Monday.
That’s what sponsors pay for. Every euro goes back into the community as more courses, better tooling, and more events. The trade is straightforward: companies get access to an audience that’s genuinely hard to reach through normal channels, and 100,000 people get an education they don’t have to pay for.
About the community
We started in September 2020 as a Slack group for people who wanted to talk about data. Six years later we’re the largest online community in this space, and we’ve built a full education programme around it.
We run five free cohort-based courses a year, all open-source and all awarding certificates on completion: Data Engineering Zoomcamp, MLOps Zoomcamp, LLM Zoomcamp, Machine Learning Zoomcamp, and AI Dev Tools Zoomcamp. Together they draw more than 60,000 registered learners a year.
We’ve run over 20 cohorts since the first Machine Learning Zoomcamp in 2021, and more than 150,000 people have registered for one of our courses. Because the materials live permanently on GitHub and the lectures stay on YouTube, each cohort keeps attracting new learners long after it wraps up.
Our weekly newsletter goes out every Monday to more than 130,000 subscribers, covering community news, upcoming events, new course modules, and the articles we’d recommend that week.
We’ve been recording the podcast since February 2021 and have published more than 200 episodes across 24 seasons, which adds up to over 200 conversations with practitioners and engineering leaders about how they actually do the work.
On YouTube we have over 600 videos and 81,000 subscribers, where we publish course lectures, workshops, podcast episodes, and live launch streams, all free to watch.
Our Slack community has almost 100,000 members who show up every day, with dedicated channels for each course, for job hunting, and for the questions people are too embarrassed to ask at work.
We also run a book club where members discuss a book with its author, plus regular in-person events for the Berlin data community.
All of that output is what gives sponsors something real to attach their name to. We’re not a mailing list that occasionally sends an ad. We’re an education programme with an audience that keeps showing up because the material is genuinely useful to them.

Sponsorship formats
Weekly newsletter
Our newsletter goes out every Monday to more than 130,000 subscribers. It’s the most direct way to put something in front of the whole community in a single send, and it’s where most sponsorships start.
A sponsored primary slot at the top of the weekly newsletter
There are three placement types:
- Primary slot. The top of the newsletter, above everything else, with your headline usually becoming the subject line of the issue. This is our most visible placement and the right choice for a major launch, a course, an e-book, or a guide. Expect 700 to 1,500 clicks.
- Secondary slot. Positioned in the middle of the newsletter alongside community content, and well suited to events, webinars, conferences, and community initiatives. Expect 250 to 300 clicks.
- Stand-alone email. A dedicated send to the entire list with no other sponsors or content, on a date and time you choose. This works best for launches and lead-generation campaigns. Expect 700 to 2,000 clicks.
Every placement includes a content template we build together, plus a report with opens, clicks, and click-through rate once it’s run.
Free courses (Zoomcamps)
This is our deepest format, and the one sponsors come back for year after year.
We run five free courses a year, each with thousands of registered learners:
| Course | Starts | Learners per cohort |
|---|---|---|
| Data Engineering Zoomcamp | January | 20,000+ |
| MLOps Zoomcamp | May | 10,000+ |
| LLM Zoomcamp | June | 10,000+ |
| Machine Learning Zoomcamp | September | 10,000+ |
| AI Dev Tools Zoomcamp | November | 10,000+ |
A sponsored module inside a Zoomcamp course
There are three levels of integration:
- Mention. Your logo on the course page, a mention in the launch stream, a shout-out in the official Telegram channel, and encouragement for students to try your product. Optionally, a demo video of up to 10 minutes. Typically 5,000 to 10,000 views.
- Workshop. A hands-on session inside a course module, live-streamed as part of the curriculum, where students apply the module’s concepts using your product. Includes a dedicated homework assignment with three questions, and optionally a raffle for participants. Typically 5,000 to 10,000 views.
- Full module. Our deepest integration: your tool is used to teach an entire topic across 5 to 10 lessons, with a 6 or 7 question homework assignment built around your product, plus office hours with participants. Open-source tools only. Typically 10,000 to 50,000 total views.
Course sponsorships work better than most formats for four reasons:
- High-intent adoption. Learners install your tool and follow step-by-step labs with it. They don’t click an ad, they actually use the product.
- Scale. 10,000 to 20,000 registered learners per cohort.
- Social proof. Learners post what they build on LinkedIn and X, which multiplies the reach well beyond the course.
- Evergreen. The content stays on GitHub and YouTube permanently, and modules we recorded years ago are still bringing in new users today.
Stand-alone workshops
These are live, hands-on code-along sessions led by your speaker and streamed on our YouTube channel to 81,000 subscribers. If you want to show your tool solving a real problem in real time, this is the fastest way to do it.
Live hands-on workshops are streamed on our YouTube channel
Here’s what’s included:
- Promotion across every channel we have: Luma, Slack, social media, and the website
- Collaborative planning so the topic fits our audience and doesn’t read like a product demo
- A live stream on our main YouTube channel
- Lead collection from attendees who opt in to share their details
- A recording that stays on YouTube permanently
- An optional dry run before going live
Workshops typically get 2,000 to 7,000 views, with around 100 people joining live. I can host the session myself if you’d prefer a familiar face guiding the audience through it.
Podcast
A focused conversation with me, published on YouTube and every major podcast platform. The listeners are data, ML, AI, and software engineering practitioners.
Podcast episodes are published on YouTube and podcast platforms
We’ve been recording since February 2021 and have published over 200 episodes. A sponsored episode includes topic planning aligned with what the community actually cares about, promotion through the newsletter and social channels, and a permanent episode page with your link. Episodes typically get 1,000+ listens.
Guest post
A practical article on the DataTalks.Club blog, built around a topic that helps data and AI practitioners solve a real problem.
Guest posts live permanently on the DataTalks.Club blog
You get editorial planning and topic review, publication on our blog, and promotion through the newsletter and social channels. We keep the article up permanently with your link. Our website gets 60,000 to 100,000 monthly visits.
In-person events in Berlin
We co-host evenings for data, ML, and AI practitioners who want to learn something new, meet peers, and talk to the people building the tools they use. Our Berlin meetup group has around 9,000 members, and 100+ people typically show up in person.
Berlin meetups bring 100+ data and AI practitioners together in person
There are two formats:
- Co-hosted meetup. We organize an evening together with your team, with practical talks, a panel or Q&A, and networking time. We handle promotion through Meetup and community channels, registration, attendee communication, and check-in. Optional sponsor table, swag, or giveaway.
- In-person workshop. A hands-on session where participants learn a concrete skill, build something with it, and connect what they learned to your product. I lead it, with live guidance and Q&A, plus optional recording.
My personal social media
Personal recommendations from me, shared on both LinkedIn and X:
- LinkedIn: 67,000 followers, 10,000 to 45,000 impressions per post
- X: 29,000 followers, 2,000 to 10,000 impressions per post
Personal recommendations on LinkedIn and X
Formats include videos about a product or event, posts with custom media and a recommendation, and giveaways. These read as personal recommendations because that’s what they are. I write them myself.
Something else
Some of our best collaborations weren’t on any menu. We’ve run swag giveaways, hackathons, course design collaborations, roundtable discussions, and sponsored community lunches. If you have something in mind that doesn’t fit neatly into one of the formats above, tell us and we’ll be honest about whether we think it’ll work.
Sponsor feedback
At Prefect, we sponsored multiple conferences such as PyCon and KubeCon. At startup price, you pay $10k-$15k USD to have a booth for 2-3 days. We got around 200-300 people stop by the booth, a lot of which are existing users. We maybe got 4-5 real new users.
Compare this to MLOps Zoomcamp where we had around 300-400 homework submissions. There are also a lot of people who just watch the courses without doing the homework. Some of these people are in brand name institutions too. I’ve seen people from Micron, IBM, Accenture taking the course to name a few.
Beyond MLOps Zoomcamp, the DataTalks.Club Slack channel is very big on democratizing high quality information to people trying to break into industry. Sponsoring the initiative feels more like it goes to a good cause in comparison to conferences.

Collaborating with DataTalks.Club for the Data Engineering Zoomcamp on data ingestion went way better than we thought. We didn’t just hit our target audience; we attracted a mix of beginners and experts from diverse backgrounds.
The workshop got over 10,000 views on YouTube. Plus, the participants really put the word out, doing a lot of the marketing legwork for us. Just last week, we were featured in two podcasts, and the number of people trying out dlt doubled. Our Slack community also saw a 25% increase in a month, largely thanks to the workshop.
This workshop wasn’t just another content we did, it changed the game regarding dlt’s exposure to our data audience. Besides addressing the professionals who took the course, DTC put dlt on the radars of other SaaS vendors who started integrating dlt into their products.

We sponsored Module 7 of Machine Learning Zoomcamp, which covers production-ready machine learning using BentoML. Over 165 students attempted the homework, and many used BentoML in their midterm and final projects. Some units in the module had over 1,000 views, and we also noticed a lot of positive social media posts about BentoML.
Compared to other sponsorship opportunities we evaluated, ML Zoomcamp aligned more with BentoML’s developer-focused approach.

The Valohai team was looking to connect with more data scientists and ML pioneers. That is when we came across DataTalks.Club community.
Thanks to Alexey, who was really easy to talk to and very fast to respond, our ebook has found the right audience through the newsletter and Alexey’s personal recommendations on LinkedIn.
This was one of the most fruitful collaborations in terms of lead acquisition.
Henrik Skogström, Head of Growth, Valohai
When we kicked off a project which required some talented Data Scientists to come and help one of our clients, NASA, the challenge was speed. We were in a rush and we needed quick access to an engaged community. We found DataTalks.Club, collaborated with Alexey to create content through 3 channels: the community Slack, email newsletter and his personal LinkedIn feed.
Outcome: the lowest candidate acquisition cost we’ve seen across all channels this year.
Nathan Jefferson, ex-Topcoder, Founder of IMBALANCE
DataTalks.Club stands as one of the strongest AIIA communities, with a wide range of seasoned and aspiring data enthusiasts. DataTalks.Club continually delivers excellent content and consistently drives highly engaged people to AIIA events and research.

Community feedback
Sponsor testimonials tell you we’re pleasant to work with. What matters more, though, is whether the audience actually values what we put out. Here’s what learners have written about us on their own blogs, without being asked or paid.
I love the zoomcamp in really different aspects. All aspects were well managed for building the best community, the best learning experience with well connected and like-minded people around the world. I have never seen such a connected and active community for a while and it made me motivated. Data Talks Club builds an incredible community with people that are interested in data, where everyone is open to sharing thoughts, helping each other and creating connections over the globe.
Irem Ertürk, Data Engineering Zoomcamp by Data Talks Club
Credit to the course instructors here because they did make the concepts understandable to someone like me. DataTalks club maintains an active community where they will answer any doubts you have regarding the course and also data engineering in general. The slack community is always active.
Work-In-Progress Data Engineer, I participated in the Data Engineering zoomcamp
The course covers a broad range of topics quite relevant to data engineering and is well-organized. So far, I’ve been enjoying quite a lot. Kudos to the organizing team.
Mahdi Moosa, Musings on the Data Engineering Zoomcamp
That’s the difference between renting an audience and being part of a community. Our members write about our courses because they got something real out of them, and that goodwill is what your sponsorship attaches to.
Companies that have sponsored us
AI Infrastructure Alliance, Aiven, Anaconda, Arize AI, Astronomer, Atlan, BentoML, Bruin, dltHub, Double Cloud, dstack, Exasol, Iterative, JetBrains, Kestra, Mage, Nebius, NVIDIA, Prefect, Qwak, Saturn Cloud, Scale AI, Snorkel AI, Snowflake, Snowplow, SODA, Tecton, Temporal.io, Toloka, Valohai, Weights & Biases, WhyLabs, and WikiMedia.
Many of them have come back more than once.
How it works
Every sponsorship follows the same five steps:
- You email us with what you’re trying to achieve, whether that’s adoption, leads, hiring, or awareness for a launch.
- We recommend a format. Sometimes that means suggesting a cheaper option because we think it’ll actually work better than the one you asked about. We’d rather you get a good result and come back than overspend once.
- We build the content together. You send a draft or a brief, we edit it so it reads like something our community wants to engage with, and you approve the final version.
- It runs on a date you’ve agreed to.
- You get the numbers: opens, clicks, views, attendance, submissions, whatever applies to the format.
Our rules
These aren’t negotiable, and they’re the reason sponsored content still works here:
- We never share member data. No sponsor gets access to email addresses or personal information. The only leads that get shared are from people who explicitly opt in during workshops and events.
- Sponsored content is always labelled. Our community knows when something is paid for.
- Relevance comes first. If we don’t think a placement will resonate with our audience, we’ll tell you before you spend money on it.
- Full course modules are for open-source tools only. We’re not going to teach thousands of learners a workflow they can’t run without a licence.
Supporting us as an individual
Not every supporter is a company. If you’re a community member who has got something out of our courses or the newsletter and you’d like to help keep them free, you can support us through GitHub Sponsors. Contributions of any size go towards the same things sponsorship money does: our free events, our educational content, and the infrastructure that keeps the community running.
Talk to us
I’ve covered the formats we run most often here, but this isn’t the full picture. There’s a lot we can do together, and the best collaborations usually end up being some combination of the options above rather than one of them on its own.
So the easiest next step is simply to get in touch:
Alexey Grigorev, founder of DataTalks.Club: alexey@datatalks.club
Email me and I’ll send you our media kit, which goes into more detail on every format, what each one costs, and the numbers behind them. From there we can talk through what you’re trying to achieve and work out which combination makes sense for you.
You don’t need to have it all figured out before you write. Tell me roughly what you’re aiming for and what you have to work with, and I’ll tell you what I’d recommend. If I don’t think we can help, I’ll say that too.
Frequently asked questions
Companies that sell to data engineers, ML engineers, AI engineers, data scientists, and analytics teams. That includes developer tool vendors, cloud and data infrastructure providers, ML and LLM platforms, observability and orchestration tools, open-source projects looking for adoption, conferences and events looking for attendees, and recruiters hiring data talent. If your buyer is a practitioner rather than a procurement department, our audience is a good fit.
Our weekly newsletter (three placement types, including a dedicated stand-alone send), free Zoomcamp courses (a brand mention, a hands-on workshop inside a module, or an entire course module built around your tool), stand-alone live workshops streamed on YouTube, podcast episodes, guest posts on the DataTalks.Club blog, in-person Berlin meetups and workshops, and personal recommendations from Alexey Grigorev on LinkedIn and X. You can combine formats into a single campaign.
Pricing depends on the format and on how many placements you book. Newsletter placements are the most accessible entry point, while full course modules are the deepest and most expensive integration. Email alexey@datatalks.club and we’ll send you our media kit, which lists the current rates for every format along with the numbers behind them, plus a recommendation for what fits your goals and budget.
We never share subscriber email addresses or personal information with sponsors. For workshops and events, attendees can opt in to share their contact details with you, and only those opt-in contacts are passed on. This is a hard rule and it is the reason our audience trusts what we send them.
Yes, always. Sponsored newsletter placements carry a “[Sponsored content]” label, sponsored articles and workshops are identified as such, and course sponsorships are disclosed on the course page. Our community knows when something is paid for, which is exactly why sponsored content still performs well here.
You can send us a draft, and we’ll adapt it. Every placement goes through a content template that we refine together before it runs. Copy that reads like a vendor ad underperforms with this audience, so we push toward the technical, specific version of your message. You approve the final version before it goes out.
After a newsletter placement runs, you get a report with opens, clicks, and click-through rate. For workshops and courses, you get view counts, live attendance, and homework submission numbers where applicable. For podcasts and articles, you get listen and traffic numbers. We share the actual data, including when a campaign underperforms.
Newsletter slots are typically booked two to four weeks out, and popular weeks go earlier. Course sponsorships need the most lead time, since the content has to be built into the curriculum before a cohort starts. Our courses launch in January (Data Engineering), May (MLOps), June (LLM), September (Machine Learning), and November (AI Dev Tools), so plan a couple of months ahead for those.
Yes. Many of our sponsors were Series A or earlier when they first worked with us, and several ran their first developer marketing campaign with us. Newsletter placements and podcast episodes are the usual starting point for smaller budgets. Full course modules are open-source only, which also makes them a fit for young projects building adoption.
Yes, and some of our best collaborations started that way. We’ve done swag giveaways, hackathons and competitions, course design help, roundtable discussions, and sponsored community lunches. If you have an idea for reaching data and AI practitioners, email us and we’ll tell you honestly whether we think it will work.
