Breeze real estate marketplace app on mobile devices showing property listings and map search

PropTech MVP Built in 6 Months, Client Raised €2.2M

We built Breeze — a real estate marketplace with smart matching algorithms, multi-platform integration, and geodata optimization that reduced API costs by 2x-5x. The client successfully raised €2.2M seed funding after launching the MVP we delivered in 6 months.

Geodata APIs can be expensive at scale. We engineered a caching and prediction system that cut API costs by up to 5x while making the app 40% faster.

🎯The Challenge

Finding apartments in Germany's competitive rental market is notoriously difficult. Tenants spend weeks searching across fragmented platforms, while landlords struggle to manage listings across multiple sites and filter through hundreds of unqualified inquiries.

Breeze needed to build a revolutionary platform that would streamline this process with smart matching algorithms, but faced a critical technical challenge: geodata APIs (for distances, points of interest, and travel time) were expensive and slow — each user request would multiply costs exponentially as the platform scaled.

💡Our Solution

We built native iOS and Android apps using our mobile app development expertise with React Native, alongside a responsive web platform. The dual-role system allows users to operate as tenants or landlords seamlessly.

To solve the geodata cost problem, we engineered smart caching strategies, batched API requests from 7 to 1 per apartment, introduced a map grid clustering concept, and built a prediction algorithm that calculates transportation time with 10-15% accuracy in just 50ms — compared to 7 seconds without optimization. This reduced API bills by 2x-5x while improving app performance by 40%.

Transformation Overview

Before

Traditional Process

Fragmented search experience
Tenants manually searched multiple platforms, wasting hours on duplicate listings
Manual listing management
Landlords posted to each platform separately, creating inconsistent information
High API costs at scale
Each property required 7 separate geodata API calls, making scaling prohibitively expensive
Slow location calculations
Travel time queries took 7+ seconds per request without caching
Generic matching
No intelligent matching between tenant needs and property features
After

Digital Solution

Unified discovery platform
Single app with map-based search and smart recommendations
Optimized API usage
Smart batching reduced requests from 7 to 1, cutting costs by 2x-5x
Lightning-fast predictions
Custom algorithm calculates travel time in 50ms with 10-15% accuracy
Smart matching algorithm
Intelligent matching system connecting qualified tenants with ideal properties
Professional using mobile app to search for apartments with map-based property discovery

🤖

Smart Matching Algorithm

Advanced algorithm matches tenant preferences with property features, scoring compatibility and surfacing best matches first based on location, budget, amenities, and lifestyle requirements.

📍

Smart Location Search

Map-based discovery with custom radius settings, POI proximity analysis (schools, public transit, shopping centers), and accurate commute time calculations to workplace or preferred destinations.

💬

Integrated Messaging

Real-time chat between tenants and landlords with automated responses, document sharing capabilities, viewing request scheduling, and application status tracking—all within the app.

📊

Landlord Analytics Dashboard

Comprehensive performance tracking with listing view metrics, applicant quality scores, response rate analysis, market positioning insights, and competitive pricing recommendations.

🔔

Intelligent Notifications

Smart push alerts for new property matches, viewing requests, application status updates, price drops on saved properties, and emerging market opportunities tailored to user preferences.

Application Process Flow

01
🎯

Discovery & Planning

Defined dual-role system architecture and API optimization strategy

We conducted comprehensive discovery workshops with the Breeze team to understand the German rental market dynamics, user personas (tenants vs landlords), and technical challenges. Mapped out the dual-role system architecture where users can switch between tenant and landlord modes seamlessly, and identified the geodata API cost problem as a critical optimization target.

02
📱

Native Mobile Development

Built iOS and Android apps with React Native for fast time-to-market

Developed native mobile applications using React Native to share code across iOS and Android while maintaining native performance. Implemented map-based property search, instant messaging, user profiles, and push notifications. The cross-platform approach reduced development time by 40% compared to native iOS and Android separately.

03
🗺️

Geodata Optimization

Engineered smart caching and prediction algorithms to reduce API costs

Built a sophisticated geodata optimization system including: request batching to reduce 7 calls to 1 per apartment, map grid clustering to group nearby requests, intelligent caching layer, and a custom prediction algorithm for transportation time that achieves 10-15% accuracy in just 50ms. This reduced third-party API costs by 2x-5x while improving performance by 40%.

04
🔗

Multi-Platform Integration

Connected with ImmoScout24, eBay Kleinanzeigen, and other German platforms

Integrated with APIs of major German real estate platforms to enable automatic listing distribution. Landlords can post once on Breeze and have their property appear on ImmoScout24, eBay Kleinanzeigen, ImmoWelt, and other sites simultaneously. Built synchronization logic to handle updates, deletions, and applicant tracking across platforms.

Launch & Funding Success

Platform launched and client raised €2.2M seed funding

Successfully launched iOS and Android apps on App Store and Google Play. The platform quickly gained traction with 20,000+ daily active tenants and 1,000+ apartments listed daily. The technical excellence and market validation helped Breeze raise €2.2M in seed funding in April 2023, validating the product-market fit and our development approach.

Technology Stack

We selected proven technologies optimized for cross-platform mobile development, scalable backend infrastructure, and cost-effective geodata operations.

Development timelines depend on complexity and feature scope. An MVP with basic matching functionality takes 3-4 months. Full-featured platforms with native mobile apps, smart matching algorithms, geodata integration, and admin panels typically require 6-9 months. Our Breeze project was delivered in 6+ months with iOS, Android apps, and web platform ready for launch.

Yes, we specialize in optimizing third-party API usage. For Breeze, we reduced API costs by 2x-5x through smart caching, request batching (from 7 to 1 per apartment), map grid clustering, and building prediction algorithms for transportation time. These optimizations also improved app performance by 40% while maintaining accuracy within 10-15% error rate.

An MVP focuses on core features to validate market demand: basic property listings, search, user accounts, and messaging. It's faster to market (3-4 months) and costs less ($50-100K). A full platform adds smart matching algorithms, advanced filters, payment processing, analytics, admin panels, and native mobile apps. Full development takes 6-12 months but provides a complete competitive solution.
