What is Captain Data?
Captain Data provides a single, powerful API designed for developers and revenue teams to access and automate buyer intent data. It's built to eliminate the complexity of integrating multiple, fragile data sources, allowing you to build smarter sales tools, train more effective AI agents, and supercharge your revenue engine with reliable, real-time insights.
Key Features
🔎 Unified Profile Discovery & Enrichment Our Buyers Profile API is your definitive source for B2B data. Instead of juggling multiple providers, you can make a single API call to discover and enrich company and contact profiles from over 30 web sources, including LinkedIn and Sales Navigator. This process uses a sophisticated "waterfall" model to ensure you receive the most accurate and complete data available.
📡 Real-Time Buyer Signal Detection Go beyond static profiles by tapping into dynamic buyer intent. The Signals API allows you to detect meaningful interactions in real time, such as who is liking relevant posts, which companies are hiring for specific roles, or when a key contact changes jobs. These signals provide the critical context needed to engage with prospects at the perfect moment.
🤖 Scalable LinkedIn Engagement Automate outreach on LinkedIn with confidence. Our Engagement API lets you programmatically send connection requests, messages, follow profiles, and interact with posts at scale. Crucially, it includes a "Smart Limits" feature that intelligently manages activity to work within LinkedIn's usage policies, ensuring your operations are both stable and reliable.
⚙️ Automated Data Workflows Connect data extraction and engagement into seamless, automated processes. You can use pre-built workflow templates or build your own to chain actions together—for example, extracting a list of leads from Sales Navigator, enriching their profiles with verified emails, and then sending the data directly to your CRM or sales engagement platform.
