Passionate

We are passionate about what we do — each and every one of us. That passion drives the quality of our work and the depth of our client relationships.

Innovators

We are never content with the status quo. We continuously refine our methodology and reimagine how technology and AI can amplify human coaching.

We listen deeply to understand your unique challenges. We pride ourselves on serving clients with rigor, insight, and a commitment to exceeding expectations.

We measure our success on your results. Lasting transformation and measurable business impact — that's what we deliver.

High-Touch, High-Tech

Years of Experience

Founded on 25+ years of proven coaching methodology. Our commitment: help organizations and leaders achieve breakthrough results at scale.

Our Process

The foundation behind every engagement

Every Skyline G engagement — from 1:1 executive coaching to scaled programs — is built on this proven four-step framework.

01

Assess Opportunities

Comprehensive evaluation using our proprietary 360 and diagnostic tools identifies strengths, growth areas, and the exact competencies to develop.

02

Prioritize Objectives

Leaders, managers, and coaches align on the highest-impact goals — ensuring every session is focused and connected to real business outcomes.

03

Apply New Learning

Real-world application reinforced through 1:1 coaching sessions and our Leadership Skills AI Coach supporting leaders between every session.

04

Measure Results

Quantitative and qualitative metrics track progress and ROI. Non-confidential data is shared with sponsors for full transparency throughout.

What We Believe

Three core values that guide everything we do.

Our values aren't marketing language — they're embedded in how we select coaches, design programs, measure results, and serve clients.

Human First

Technology amplifies human insight; it doesn't replace it. The best leadership development combines the irreplaceable qualities of expert coaches — intuition, discernment, nuanced observation — with data and AI. We will never deliver coaching without a human at the center.

Data Informed

We don't guess. Every coaching engagement is grounded in precise assessment data. We measure progress rigorously. We track outcomes across thousands of leaders to continuously improve our methodology. What we say works, we can prove it works.

Results Obsessed

We exist to change behavior and create measurable impact — not to feel good in the moment. A 2-day workshop might be fun; we're interested in lasting transformation. Every hour invested in our programs should translate to observable business results.

Our Founders

The leadership team behind Skyline G.

Skyline G was founded by a clinical psychologist and a data scientist united by one goal: build the most effective human-led, AI-amplified leadership development company in the world.

Thuy Sindell, PhD — Co-Founder and President, Executive Coaching Division at Skyline G
Founder & President, Executive Coaching Division

Executive coach, entrepreneur, and author with 25+ years of coaching experience spanning Fortune 500 companies, high-growth startups, and organizations across technology, financial services, healthcare, and beyond. Thuy manages a global network of 120+ coaches, facilitators, and consultants — and her methodology is embedded into every Skyline G engagement.

She is also the founder of two software startups. Hit the Ground Running, a pioneering employee performance platform, was acquired by Kenexa (now IBM). Her second company, Knowledge Genie, brought expert knowledge to digital audiences at scale. This technology DNA is what ultimately powered the creation of Skyline G's proprietary Leadership Skills AI Coach — built on 25+ years of Thuy's methodologies and coaching knowledge.

"The most powerful coaching moment isn't in the data — it's in the pause, the hesitation, the thing the leader almost says but doesn't. That's where transformation lives."

A Partnership Built on Shared Mission

Thuy and Milo's partnership represents the heart of Skyline G: psychology meets technology. Neither leads without the other. Coaching decisions are informed by data.
