Introduction<\/strong><\/p>\n

On June 14, during our annual professional conference, we officially introduced LEO Gantt<\/strong>.<\/p>\n

LEO Gantt is a cloud-based project scheduling engine designed for working with timelines, tasks, dependencies, and assignments inside Microsoft 365.<\/p>\n

It is a proprietary product developed by Leo Consulting<\/strong> \u2014 the leading project management implementation company in Ukraine, with hundreds of delivered projects, 16 industry conferences, and a nationwide professional community.<\/p>\n

Development of LEO Gantt began on February 2, 2024, and its first public release was announced on June 14, 2025, reflecting a focused, strategic development process.<\/p>\n

Why We Built Our Own Scheduling Engine<\/strong><\/p>\n

When we started developing LEO PPM in 2022, the choice of a scheduling tool was straightforward.<\/p>\n

At that time, Project for the Web (now Planner Premium) was the only fully cloud-native scheduling solution available in the Microsoft ecosystem.<\/p>\n

\"\"<\/p>\n

Planner Premium is a reasonable tool for a specific class of projects \u2014 short, low-complexity initiatives with limited dependency logic.<\/p>\n

However, after hundreds of real implementations, one thing became consistently clear:<\/p>\n

Modern cloud schedulers are optimised for lightweight execution, not for controlled delivery.<\/p>\n

Microsoft continues to invest in Planner Premium, but its strategic direction is clearly focused on AI-driven user experience, not on expanding classical project management capabilities such as dependency logic, baselines, resource effort tracking, or portfolio-grade predictability.<\/p>\n

By 2023, it was evident that waiting for these capabilities to emerge was no longer a viable strategy.<\/p>\n

If predictability matters, scheduling cannot remain a compromise.<\/p>\n

After thorough market and architectural analysis, we decided to develop our own scheduling engine to meet the specific needs of complex, dependency-heavy projects and ensure predictable delivery.<\/p>\n

On February 2, 2024, development of LEO Gantt began.<\/p>\n

From Concept to Product<\/strong><\/p>\n

Eighteen months later, on June 14, 2025, at the Strategic Project Conference, we presented a new version of LEO PPM powered by LEO Gantt.<\/p>\n

Our goal was clearly defined from the beginning:<\/p>\n
