As answered by people managing ProsperStack and Eventum.run.
ProsperStack's answer
Our vision is to be the ultimate subscriber acquisition and retention machine. It takes a team of experts to build the perfect solution to your subscriber churn. Luckily, we've got expertise in every area of the subscription economy.
Eventum.run's answer:
The author works on a data analytics platform similar to Splunk, where every customer demo needs a believable case running on data that looks alive. The team generated demo data with Splunk Eventgen, but the workflow never felt convenient, so around 2023 he started building his own generator. It grew into Eventum, now used by his SIEM team and data engineers daily.
ProsperStack's answer
Eventum.run's answer:
Most data generators produce random values at a flat rate. Eventum also models behavior: traffic follows cron schedules, intervals or statistical time patterns with peaks, bursts and quiet periods, and templates persist state between events - three scopes of state plus a finite state machine mode for multi-step scenarios like user sessions.
ProsperStack's answer
High volume subscription businesses that allow customers to cancel online.
Eventum.run's answer:
Data engineers, SIEM and detection engineers, and developers who need realistic data for testing pipelines, live demos, seeding databases or load testing - teams that would otherwise write throwaway generator scripts.
ProsperStack's answer
ProsperStack is tech-stack agnostic. We offer more integrations than anyone on the market, including custom API integrations, so you can use all your favorite tools to reduce customer churn.
Eventum.run's answer:
Libraries like Faker give you fake values - Eventum gives you the whole pipeline: scheduling, templating, state, and parallel delivery to ClickHouse, OpenSearch, Kafka, files or any HTTP endpoint. And it ships with Eventum Studio, a web UI where you preview and debug events before anything goes live.
Eventum.run's answer:
Python (FastAPI, Pydantic, Jinja2) for the engine, CLI and REST API; React + TypeScript for the Eventum Studio web UI. Ships as a pip package and Docker image.
