SINAI Technologies Achieves 150%+ Increase in Employee Engagement with HR Software, 15Five

The Customer’s Core Challenge

SINAI Technologies, an AI-powered platform for carbon management, operates in one of the most specialized and competitive talent markets: climate tech. Recognizing the critical importance of retaining highly skilled professionals, Dominique Geroulis, Head of People Operations at SINAI, identified an opportunity to strengthen engagement and build a more connected employee experience.

The challenges:

• High-cost recruiting made retention pivotal. Hiring experts in SINAI’s niche field was expensive, making employee retention a top priority.
• No clear path for growth. Without a consistent framework for feedback or development, employees lacked visibility into career progression.
• Low engagement scores reflected structural gaps. Scores revealed that employees weren’t feeling supported or developed, signaling the need for more intentional people systems.

While employee engagement scores indicated room for improvement, Dominique understood that the underlying issue wasn’t culture, it was structure. Recruiting and onboarding experts in this niche field came with significant costs, making retention a strategic priority. Before adopting 15Five, SINAI lacked a consistent framework for employee feedback and career growth, which made it harder for team members to see a clear path forward.

Dominique set out to change that by creating a more intentional people strategy centered on communication, trust, and development to ensure SINAI could continue attracting and retaining top climate talent.

The Solution

SINAI chose 15Five to transform its company culture and address these challenges. The solution centered on a proactive, data-driven approach to employee feedback.

Dominique implemented quarterly engagement surveys using 15Five's dashboard and people analytics to track trends and identify areas for improvement. This regular cadence and focus on transparency, sharing scores and action plans with the entire company was a breakthrough.

The "A-Ha!" Moment

The visual and user-friendly nature of 15Five's dashboard was a significant "a-ha!" moment for Dominique. The ability to present a visually appealing dashboard in leadership meetings, which showed the progress of engagement scores and a breakdown of the teams, empowered her to influence strategic decisions and strengthen leadership alignment around people priorities.

This visual, data-driven approach replaced cumbersome spreadsheets, allowing leadership to pinpoint precisely where to focus their efforts without relying on guesswork.

What Sinai Said about 15Five

“Partnering with 15Five has given us the tools and insights to take meaningful action, strengthen our culture, and empower our people to thrive. It’s not just about measuring engagement—it’s about empowering people to grow, connect, and contribute to something bigger. That’s what’s helping us strengthen our culture and drive real impact. 

— Dominique Geroulis, Head of People Operations at SINAI Technologies
