Key Features

• Direct API Speed: Queries Signal's backend GraphQL API directly without running heavy headless browsers, delivering lightning-fast scraping at near-zero execution cost.
• Strict Zero-Guessing Guarantee: Extracts only explicit, verified values directly from the investor's profile. Missing attributes remain blank rather than fabricated.
• Clean Title and Firm Separation: Isolates the investor's clean job title (such as Founding Partner, Managing Partner, General Partner) without concatenating the firm name, which is provided in its own dedicated column.
• Compact Financial Formatting: Check size ranges and sweet spots are formatted in standard real estate and venture capital notation (such as $100K - $5.0M and $1M).
• Geographic Granularity: Automatically separates locations into distinct City and State columns for easy filtering and CRM mapping.
• Dual Output Formats: Generates an Apify Dataset alongside downloadable, styled Excel (OUTPUT.xlsx) and CSV (OUTPUT.csv) files in the default Key-Value Store.
