I help founders, CEOs, and leadership teams make and defend consequential decisions before they commit significant capital, people, time, or reputation.

Scale-up leaders rarely lack advice. They have boards, investors, mentors, consultants, experts, internal teams, and increasingly AI. What they often lack is a disciplined decision process that helps them determine what the real decision is, challenge the assumptions carrying it, weigh conflicting evidence, expose tradeoffs, and decide what would cause them to change course.

I lead Consequential Decision Reviews for high-stakes choices involving growth, GTM, AI investment, senior hiring, organizational design, partnerships, market entry, funding, capital allocation, and execution risk.

The result is not simply another recommendation. Leaders gain the clarity and confidence to walk into a board meeting, investor discussion, institutional review, funding round, or executive session and explain:

what decision is actually being made
why it is defensible
what evidence and assumptions support it
what remains uncertain
and what would change the decision

For organizations that want a more durable capability, I build customized Executive Decision Rooms. These are governed thinking environments where consequential decisions are framed, challenged, documented, revisited, and connected over time.

The reasoning behind important decisions no longer disappears into meetings, slide decks, inboxes, or people’s heads. The organization retains a decision memory: what was believed, what evidence was used, what was decided, what changed, and what was learned.

Most competitors can access similar technology, expertise, data, and capital. Far fewer possess a decision process that consistently improves executive judgment. That is the advantage I help scale-ups build.
