TheirStack

TheirStack is a technographic intelligence platform that maps which technologies companies are using, making it easy to identify high-fit accounts based on tech stack signals. Unlike traditional databases, TheirStack provides continuously updated technology adoption data that reflects real hiring signals, job postings, and web detection — giving you a more accurate and timely view of what tools your prospects are running. With Bitscale, you can connect your TheirStack API key to pull tech stack data for any company domain or LinkedIn URL directly into Grids, powering ICP filtering and tech-aware personalization at scale.
