Lead Frontend Engineer - Gatsby
About Gatsby
Gatsby is modernizing how enterprises manage executive relationships and event workflows. Used by leaders in venture capital, finance, enterprise, and nonprofits, Gatsby replaces disjointed planning tools with a streamlined, intelligent event CRM platform that powers everything from personalized invites to real-time guest tracking.
Gatsby customers organized over 1,000 events in 2023 and sent 125,000+ communications through the platform — growing 10x year-over-year. With an ambitious roadmap ahead, we’re expanding from events into broader relationship workflows like recruiting, sales, and executive communications.
