Evolving FSQ Open Source Places
October 8, 2025 by Vikram Gundeti

In November 2024, we took a bold step in open-sourcing our Places dataset with a hypothesis that a community driven approach is the only way to create a sustainable and robust places dataset that can serve the needs of diverse problem domains. Our thesis has been validated with the tremendous progress we have been able to make in improving this open dataset since its inception.

Increased adoption: Our S3 listing is downloaded from more than 5000 unique IPs every month, a steady increase from 500 unique IPs when we first launched. More than 250k queries are executed on our Snowflake listing every month. And we have 3000+ monthly downloads of our dataset on HuggingFace.
Accelerated data improvements: We continuously refined our dataset adding more than a million places since launch with a monthly high of 160k+ new places just in September. More than 27 million edits have been proposed by our Placemaker community in the last year out of which close to 17 million have been resolved.
Diversified Placemaker community: We have been able to diversify our community from just the users of our apps to a broader user base with around 2000 Placemaker sign-ups from the open-source community using our Placemaker tools. We have also seen business owners gravitating towards our Placemaker Tools to update their own listings.

Today, we’re taking the next step in that journey with updates that will strengthen our collaborative ecosystem and unlock even greater potential for data improvement.
The Power of Placemaker Tools
At the heart of our community-driven approach are our Placemaker Tools, which enable anyone to contribute to and improve the OS Places dataset. Through these tools, contributors can:

Add new places: Submit businesses, landmarks, and points of interest missing from the dataset
Update existing information: update addresses, phone numbers, business hours, and other details
Verify and validate: Confirm the accuracy of place information through community consensus
Enhance place details: Add categories, attributes, and rich contextual information
Report closures: Flag businesses that have permanently closed or relocated

These tools have proven that when given accessible ways to contribute, people eagerly improve the data that powers their favorite applications. The 27 million edits proposed through Placemaker Tools demonstrate the power of community-driven data maintenance at scale. As we evolve our approach, Placemaker Tools remain central to our strategy. By creating stronger connections between dataset consumers and the improvement ecosystem, we can channel community efforts where they matter most, whether that’s improving coverage in underserved regions, updating time-sensitive information, or enriching place details for specific use cases.
Unveiling the Next Chapter
Our October release transitions FSQ OS Places from public S3 bucket access to our new Places portal. Users can register, generate an access token, and retrieve the data through an Iceberg catalog. The data remains completely free with proper attribution under our Apache 2.0 license.
Why This Evolution Matters
Over the past year, we’ve seen incredible adoption of our dataset across diverse industries and use cases. But despite the widespread adoption of our OS Places dataset, the end users of applications built on this dataset rarely know it is even sourced from Foursquare or that they have an opportunity to improve it using our Placemaker Tools. In our current anonymous distribution model, there’s no path from “using an app with great location data” to “helping improve that location data.”
A root cause here is a lack of awareness. When users discover that their favorite applications are powered by a community-driven dataset, many become eager contributors through our Placemaker Tools. This creates a virtuous cycle: better data enables better applications, which reach more users, who contribute more improvements, creating even better data.
That is why we’re introducing this new approach to build connections with the direct consumers of our dataset and work together to spread awareness of FSQ OS Places and empower their user communities to contribute through Placemaker Tools.
What This Means for You
Accessing the dataset
FSQ OS Places will now be accessible through three primary channels:

New Places Portal: Visit our new portal to create your free account and generate an access token. Use the access token to retrieve OS Places data from our Iceberg catalog.
Snowflake: Access OS Places data from the Snowflake marketplace with the same ease as before.
HuggingFace: Get approved for access to the OS Places data through HuggingFace by providing your contact information.

Attributing to Foursquare
The data remains completely free with proper attribution under the Apache 2.0 license. To ensure required attribution, we recommend the following:

If using/distributing the dataset in flat file form as-is or after making changes/modifications: include this NOTICE.txt file, which may be modified to include an additional notice of your changes/modifications, if any.
If using/distributing the data in API form as-is or after making changes/modifications: include a copy of the content from this NOTICE.txt file prominently in your developer documentation for such API, which may be modified to include an additional notice of your changes/modifications, if any.

Connecting With The Community
This new approach creates direct connections between you, the dataset consumers, and our Placemaker community. When we know which applications are powered by FSQ OS Places, we can help you surface improvement opportunities to your end users, empowering them to become contributors who enhance the data that powers their favorite applications.
When we understand what matters to you — accurate business closures, comprehensive category coverage, and more — we can channel the community’s efforts where they will have the greatest impact. Your needs inform community priorities, their contributions power your applications, and your users become their fellow contributors. The cycle strengthens itself. Join our Placemaker Discord to connect directly with the community and collaborate on data improvements.
Transition Support
We are committed to ensuring a smooth transition for everyone. You can access the OS Places data from the past releases through our public S3 bucket but all future releases (starting from October 2025) will only be accessible through the three supported channels.
The September 2025 release is already available through our new portal, giving you immediate access to our latest data while you plan your transition. If you have production workloads built on top of our public S3 dataset, please join our open source slack and reach out to us at os-places@foursquare.com and we will work with you to ensure continuity of business operations.
The Road Ahead
This next chapter strengthens everything that makes FSQ OS Places powerful: community collaboration, open access, and continuous improvement. By understanding real-world usage patterns, we can identify data gaps and connect users directly with Placemaker Tools. Every application becomes a gateway for new contributors, and every contribution amplifies the value for all users.
Together, we’re building not just a dataset, but a sustainable ecosystem where location data gets better every day through the collective efforts of a global community.
Visit the new Places Portal to get started.

In November 2024, Foursquare initiated a significant evolution by open-sourcing its Places dataset based on the hypothesis that a community-driven methodology is essential for establishing a sustainable and robust data foundation capable of serving diverse problem domains. This hypothesis has been validated by substantial community engagement since its inception, evidenced by increased adoption, including monthly downloads from over 5000 unique IP addresses, and the execution of more than 250,000 queries on the Snowflake listing monthly. Furthermore, the community has driven substantial data improvements, with over a million places added and approximately 27 million edits proposed by the Placemaker community over the last year, of which nearly 17 million have been resolved.

The foundation of this community-driven approach rests on Placemaker Tools, which empower contributors to actively improve the dataset through various functions. These tools allow community members to add missing places, update existing information such as addresses and business hours, verify place accuracy through consensus, enrich details with attributes, and report closures. This process demonstrates the efficacy of accessible contribution mechanisms in achieving large-scale, high-quality data maintenance. The sheer volume of proposed edits underlines the power of this community in ensuring the data reflects real-world accuracy.

The subsequent evolution focuses on strengthening the collaborative ecosystem and addressing a critical gap: the lack of awareness among end-users regarding the dataset's origin or opportunities for contribution. The previous anonymous distribution model lacked a clear pathway connecting the act of using location data to the process of improving that data. Therefore, the new strategy seeks to foster a virtuous cycle where increased distribution awareness drives greater community contribution, which in turn results in better data for applications. This requires building direct connections between the dataset consumers and the Placemaker community to effectively channel collaborative efforts toward crucial areas like improving coverage in underserved regions or updating time-sensitive information.

To facilitate this connection and enhancement, Foursquare is transitioning the distribution model. The October release pivots the FSQ OS Places dataset from public S3 bucket access to a new Places portal that utilizes an Iceberg catalog, allowing registered users to access the data via generated access tokens. The data remains free under the Apache 2.0 license, with specific requirements for attribution, including including NOTICE.txt files or corresponding content in developer documentation when distributing the dataset or its API.

Access to the dataset is now supported through three primary channels: the new Places Portal for registration and token retrieval, the Snowflake marketplace, and access via HuggingFace. This change ensures that users are made aware of how they can participate in the ongoing refinement of the data. This evolution is designed to amplify the value of the dataset by empowering users to become active contributors, thereby creating a self-sustaining ecosystem where location data continuously improves through collective, informed efforts.
