About
Stantem needed a lead generation and management platform for the US real estate market. We built a SaaS web application where users search 150M+ properties, build targeted lead lists and run email outreach to property owners, powered by custom data pipelines, a unified lead database and Stripe subscriptions.
Challenge, approach, and impact
Unified Lead Database
Built data collection pipelines that gather US property and owner data into one deduplicated, normalized database of 150M+ records, with validation and regular updates, so every lead has one consistent record.
Lead Search & List Building
Users filter the entire US market by location, property attributes and owner data, compare and prioritize properties with custom analysis algorithms, and save targeted lead lists for outreach.
Map View for 150M+ Properties
Built a fast Map View with filtering by map bounds, optimized queries and streamlined data loading, so users can explore all 150M+ properties visually without delays.
Email Outreach Campaigns
Added email campaign functionality with a rich text editor (TinyMCE), letting users compose, format and send campaigns to their lead lists directly from the platform.
Stripe Subscriptions & Billing
Integrated Stripe for subscription management with multiple tariff plans, discounts and automated payments, making the platform revenue-ready and able to serve many independent customer accounts.
User Accounts & Secure Access
Implemented user registration, authentication and personal accounts, so each customer works securely with their own lead lists, campaigns and subscription.
Data Comparison and Analysis Algorithms
Developing dedicated algorithms for object comparison and analysis within the web application to enhance data processing capabilities and provide users with valuable insights.
