I lead go-to-market for
B2B technology companies,
transforming how they
sell, scale, and win.

CRO and GTM executive with 20+ years building data-driven revenue organizations. CISSP-certified. Former CTO. From $0 to $75M ARR across cybersecurity, AI platforms, enterprise SaaS, and technical services. I bring the technical credibility, AI fluency, and operational rigor that complex markets demand.

GTM transformation and revenue scaling

I've taken companies from zero revenue to $75M ARR and delivered $10M to $35M improvements at established organizations. This isn't incremental optimization. It's building the revenue architecture, hiring and coaching the team, then driving execution until the numbers compound. I design the GTM motion, align it across product, sales, and customer success, and lead the team through the hard middle of scaling. That includes international expansion into new markets. I've opened operations in China and the Middle East, and I've led GTM for both US-headquartered and foreign-owned companies including Swedish and Canadian organizations.

Technical buyer credibility

CISSP-certified, former CTO, and fluent in the language of CISOs, CTOs, and platform engineering teams. I sell to the buyers that generalist sales leaders struggle with, because I've been on their side of the table. In cybersecurity, AI, and enterprise SaaS, technical credibility isn't a nice-to-have. It's the difference between a 6-month sales cycle and a 14-month one.

AI-powered revenue operations

I don't just sell AI products. I run GTM operations on AI infrastructure. Pipeline intelligence, agent-assisted execution, competitive analysis, meeting synthesis, forecasting. At Calliope AI, I built the GTM motion for a secure AI development platform while using AI tooling across every revenue function. This is how GTM teams will operate in two years. I operate this way now.

Founder-to-scale GTM architecture

The hardest transition in B2B technology is moving from founder-led sales to a structured, repeatable GTM motion. I've done this multiple times: at Tehama ($0 to $27M ARR, category creation), at Broadwing (52% revenue growth and 32% ACV increase), and now at Calliope AI (10+ enterprise design partners, $140K ACV validated). I know what breaks during this transition and how to prevent it.

The SPORT5 framework

Most revenue operations teams treat GTM models and revenue flow models as interchangeable. They're not. Your GTM model is a strategic choice: PLG, sales-led, hybrid, partner-led. Your revenue flow model is how that strategy actually operates: stages, conversion rates, velocity metrics, handoff logic, measurement.

SPORT5 codifies this distinction into five pillars that give RevOps teams a clear blueprint, so they're building infrastructure that matches how revenue actually flows through the business, not systems that wag the strategy around.
