Mentimeter | Professional Services | 370 | $46M | Sweden | Ably Realtime | Ably Pub/Sub | API Management | 2019 | n/a |
In 2019, Mentimeter adopted Ably Pub/Sub in a Pub/Sub deployment to power realtime audience engagement features for presentations and virtual events. The adoption of Ably Pub/Sub provided a publish subscribe realtime messaging backbone for live polls, quizzes, Q&A and leaderboards.
The implementation established a global realtime layer that handled connection spikes reaching tens of thousands of participants, with Ably Pub/Sub responsible for high volume fanout, connection multiplexing and low latency message delivery across sessions. Functional capabilities implemented included live polling, timed quizzes, interactive Q&A flows and leaderboard updates, each integrated into Mentimeter’s presentation runtime.
Operational scope was global with headquarters in Sweden, and the migration was executed in under a month. The project shifted operational responsibility for realtime infrastructure away from product engineering, freeing engineers from realtime ops and enabling faster product innovation and iterative feature development.
Mentimeter reported that the Ably Pub/Sub deployment addressed prior reliability and scale issues and delivered a 3x increase in connection capacity, stabilizing large scale event participation and supporting continued growth of live audience engagement features.

NASCAR | Leisure and Hospitality | 2500 | $362M | United States | Ably Realtime | Ably Pub/Sub | API Management | 2023 | n/a |
In 2023, NASCAR implemented Ably Pub/Sub in the Pub/Sub category to broadcast subsampled in-car telemetry and dashboard data to Drive app users as a second screen experience across events in the United States. The deployment was explicitly focused on delivering extremely high-frequency telemetry streams and absorbing sudden audience spikes during live racing events.
Ably Pub/Sub was configured to support high-throughput pub/sub streams with source-side subsampling to control message volume and connection orchestration to handle large concurrent client populations. Functional capabilities implemented included real-time message delivery, subscription management, and scalable connection handling consistent with Pub/Sub operational patterns for live telemetry distribution.
The platform integrated with NASCAR's Drive app and telemetry pipelines to push subsampled in-car and dashboard feeds directly to fans during races. Operational coverage centered on United States events, and the environment demonstrated reliable delivery at scale with more than 370M messages during the 2024 Daytona 500 and peaks exceeding 56K simultaneous connections.
Governance and rollout emphasized stream-level configuration, automated capacity scaling, and operational playbooks for live-event incident response. The implementation removed manual capacity provisioning and enabled richer real-time fan features by providing predictable, scalable pub/sub delivery for high-frequency automotive telemetry.

Split Software | Professional Services | 100 | $10M | United States | Ably Realtime | Ably Pub/Sub | API Management | 2019 | n/a |
In 2019 Split Software implemented Ably Pub/Sub to push feature-flag events in realtime to client apps, shifting polling-based delivery to an event-driven model to meet sub-second delivery requirements for critical customers. The deployment uses Ably Pub/Sub, Apps Category . The work was scoped to the United States region and focused on reliable event propagation to mobile and web clients for Split Software feature management.
Ably Pub/Sub was configured as a high-throughput pubsub layer with dedicated channels and topic segmentation for feature-flag events, and the implementation emphasized SLO-driven delivery semantics. The Ably Pub/Sub configuration supported publication, fan-out, and ordered delivery patterns typical of event-driven feature flagging, supporting 1 trillion+ events per month and <300ms latencies for SLOs.
Integrations centered on client SDKs and the existing feature evaluation pipeline, enabling realtime event delivery to client apps and removing the need for polling-based refresh workflows. Operational coverage was regional within the United States, and message routing and channel partitioning were used to manage latency and throughput for critical customers.
Governance focused on operational reliability and SLO monitoring for event delivery, with engineering and operations teams aligning on incident procedures and message retention policies. The implementation produced reliable, low-latency propagation of feature-flag events and reduced infrastructure and operational overhead as part of the rollout.
