Tirza Hollenhorst
CEO * Founder
Tirza’s work spans the full arc of organizational life. As a fractional executive, she joins leadership teams at inflection points — CEO transitions, strategic pivots, rapid scaling — and delivers the outcomes that matter: at Clarify Health, zero attrition through a 20% reduction in force and a full strategic pivot, with $20M in additional revenue in the year following; at Blue Planet Energy, a complete product and market reset that achieved profitability with no new investment, followed by a successful CEO succession. She doesn’t advise from the outside. She leads from the inside, and she leaves the organization stronger than she found it.
Across two decades of engagements at Siemens, Airbus, Johnson & Johnson, Meta, and AMD and through her work with the Government Innovation Fellowship. Tirza has built the learning communities, leadership programs, and innovation ecosystems that sustain. Her programs produce measurable results: 80% increases in engagement, 100% promotion rates, patent filings, and new ventures. More importantly, they produce organizations that continue to grow, adapt, and perform long after the formal engagement concludes. Her work is grounded in the behavioral science of habit change, the psychology of motivation, and the neuroscience of learning — which is why it lasts. Tirza is a sought-after keynote speaker on the future of work, AI and organizational design, and what it takes to build institutions that are genuinely built to last.
- I build the people systems, operating capacity, and cultural infrastructure organizations need to perform through rapid change.
- I move fluently between strategy and execution, from shaping a three-year vision with leadership to building the practical systems that make it real.
- I lead from inside the organization during critical inflection points, including CEO transitions, strategic pivots, rapid scaling, and restructuring.
- I create leadership programs, learning communities, and innovation ecosystems that produce measurable results and continue to strengthen the organization after the engagement ends.
Philip Horváth
Chief Catalyst · 30+ Years Enterprise Transformation · Author
philip horváth works at the problem most leadership development avoids. Not the strategy. Not the technology. Not the change management framework. The human. His central claim: you cannot change what people do without developing who they are. Most programs skip that layer. He calls it half the map. He works the complete map.
He works with leaders and organizations at the exact point where transformation stalls. Not because the vision is wrong. Because the people carrying it have not yet developed the capacity to see it through. At Siemens, he built and ran an intrapreneurs bootcamp that compounded across a decade. New ventures launched. Leaders promoted at rates that outpaced organizational norms. A culture of creative ownership that outlasted any single program cycle. He does not deliver insight and leave. He builds the human capacity that carries the work forward after he is gone.
Over more than 30 years of engagements at Siemens, Airbus, T-Mobile, Vodafone, Infineon, Meta, and Bundesagentur für Arbeit, philip has built the leadership architectures, programs, and organizational cultures that hold. His work is grounded in the behavioral science of identity change, the psychology of vertical development, and the neuroscience of adult learning, which is why the results last. He brings two decades of California-metabolized leadership practice (the Bay Area lineage of conscious leadership, somatic work, and organizational transformation) integrated with the structural rigor that European corporate culture demands and rewards. Most practitioners bring one or the other. philip brings both.
philip is the founder of LUMAN and the creator of the 21 Intelligences Framework. His forthcoming book, The Relational Age, makes the case for why relational intelligence is the defining leadership capacity for the century ahead. He is a sought-after keynote speaker on leadership in complexity, AI and human capacity, and what it actually takes to develop leaders for the world that is arriving. He is based in Berlin and Los Angeles.
- I develop the human capacity behind transformation, helping leaders shift the identity, perception, and relational intelligence required to create new outcomes.
- I bridge deep human development with practical organizational execution, turning philosophy, adult development, and behavioral change into usable leadership architectures.
- I build programs and cultures that create lasting capability, including intrapreneurship, innovation leadership, and transformation work that continues beyond the formal engagement.
- I bring a rare transatlantic synthesis: California-rooted conscious leadership, somatic practice, and transformation work integrated with the rigor and pragmatism of European corporate environments.
Philip's research spans the full range of human development traditions — from the rigorously scientific to the rigorously ancient. Both are serious inquiries into the same territory.
