Overview

Horizon Talent is a leading recruitment technology platform based in Stockholm, Sweden. They specialize in talent acquisition and employer branding solutions for businesses across Europe. Since 2011, they have connected high-tier candidates with top organizations through an automated hiring ecosystem. However, they faced significant growth barriers due to soaring development costs.

They hired Prime Horizon as a development partner to provide a high-performing augmentation team at a sustainable cost. Prime Horizon implemented a comprehensive engineering model to handle the platform's complex technical scope. This included managing web crawlers, data engineering pipelines, and backend infrastructure.

The team mastered the candidate pipeline lifecycle through rapid domain onboarding. They refactored existing features and built a scalable architecture for the Applicant Tracking System (ATS). Prime Horizon also optimized the multi-channel advertising engine for platforms like LinkedIn, Snapchat, and Indeed.

The partnership resulted in a more robust platform with advanced recruitment marketing analytics. They successfully integrated localized Swedish job boards like AMS into their advertising engine. The new system supports seamless third-party interview management and background check workflows.

Prime Horizon’s resource model provided multiple developers for the same budget, accelerating feature delivery significantly. Today, Horizon Talent maintains a growing product line with a scalable and cost-effective infrastructure.
