About Us

Building Structured Performance Systems
Since 2014

GroSum was founded on a simple belief: performance systems should bring clarity, fairness, and structured decision-making - not confusion and subjectivity.

Our Story

Born from a Simple Frustration

After years of watching organizations struggle with bloated HR platforms that nobody liked using, we built GroSum - a modular performance management platform that teams actually enjoy.

Over the past decade, we've served 200+ companies across 15 countries, from fast-growing startups to large enterprises. We've shipped 235+ product releases, each one driven by real customer feedback.

Over time, GroSum evolved into a modular performance intelligence platform - integrating structured reviews, perception analysis, and continuous feedback into one coherent system. We use intelligent automation where it helps, but structure and governance always come first.

What We Believe

Our Principles

🧩

Modular by Design

Every organization is unique. Our tools work independently or together - pick what fits your needs today.

🤖

Intelligence with Practical Impact

Our AI features are built to solve real problems - writing reviews, finding blind spots - not to add buzzwords to a slide deck.

🤝

White-Glove Service

We don't just hand you software and walk away. Our team helps you set up, configure, and succeed with dedicated support.

⚡

Speed to Value

Go live in days, not months. Our streamlined setup process means you're seeing value from week one, not quarter three.
