Xiaodan Zhuang
Xiaodan Zhuang, who also goes by Dennis, is the co-founder and CEO of Greptime, a company building GreptimeDB, an open-source observability database written in Rust that unifies metrics, logs, and traces. Before starting Greptime in 2022, he spent roughly 18 years in software infrastructure, including leading the intelligent monitoring team at Ant Group where he built ultra-large-scale time-series platforms for AIOps, plus earlier stints at Taobao/Alibaba and LeanCloud. He is a long-time open-source contributor (GitHub handle killme2008) behind projects like Aviator and xmemcached, and a self-described car enthusiast who races on tracks.
Evan Kaplan
Evan Kaplan is the CEO of InfluxData, the company behind InfluxDB - the world's most popular open-source time series database with over 1.3 million developers. With nearly 20 years in CEO roles across multiple companies, he took InfluxData from a scrappy open-source project of 3,000 users to a platform handling billions of data points per second for 1,900+ enterprise customers. His path to the C-suite ran not through computer science but through environmental science degrees and years spent as a mountain guide in his late 20s - an unconventional origin story that shows up in how he thinks about resilience and long-term endurance.

A serial entrepreneur with MIT roots, he previously co-founded Sensobi (acquired by GroupMe/Microsoft) and iobeam before building TimescaleDB into a developer-beloved unicorn with $184M raised, 50,000+ developers, and enterprise customers like Akamai, Cisco, GE, IBM, Microsoft, Uber, and Walmart.
