Holidu Tech Stack

Metasearch platform for holiday rental discovery and host monetization

IT Services and IT Consulting Munich, Bayern 501–1,000 employees Founded 2014 Privately Held

Holidu operates a vacation rental metasearch engine connecting guests to hosts across Europe. The tech stack reflects a dual-layer architecture: Salesforce + HubSpot for guest-side commerce and CRM, paired with Java/Kotlin backend services (Spring Boot, Elasticsearch, PostgreSQL) for search, matching, and discovery. Active projects cluster heavily in lead generation, host onboarding (HSD module rollout), and revenue forecasting—indicating a sales-driven scaling phase focused on partner acquisition and booking volume. The hiring mix underscores this: 65 sales roles against 6 engineering, with notable gaps in analytics (insufficient marketing analytics noted as pain point) and pricing optimization logic.
