Fractional CTO & AI Operating Partner

Fractional CTO and AI Operating Partner for ambitious startups.

Co-founder and CTO of a company acquired for ~$50M, with 25+ years building software companies. I help funded startups improve engineering execution, product velocity, and operational leverage through AI-native systems.

Operating systems

Where companies get stuck

Execution failures I see repeatedly at growth stage.

Engineering velocity stalls

Teams ship slowly despite headcount. Process accumulates faster than output.

AI without leverage

Initiatives consume budget and attention but fail to change how the organization executes.

Roadmap chaos

Priorities shift weekly. Product and engineering misalign under pressure.

Post-raise scaling strain

Capital arrives before operating systems exist to absorb it.

Technical leadership gaps

Founders carry architecture, hiring, and execution without a peer-level technical operator.

Operational bloat

Coordination overhead grows. Management layers multiply. Throughput does not.

What I do

Strategic technical leadership, not a services menu.

I work at the intersection of engineering, product, and operations. Engagements are outcome-oriented and designed for founders who need a peer-level operator, not another vendor.

Fractional CTO Leadership

Executive technical leadership for founders navigating scale, hiring, architecture, and board-level technical narrative.

AI Operational Systems

Internal systems that reduce coordination overhead and turn AI from experiment into execution infrastructure.

Engineering Acceleration

Improve velocity, reduce friction, and build technical execution systems that scale with the business.

Product & Roadmap Strategy

Align product direction with engineering capacity. Restore clarity to what ships and why.

Organizational Optimization

Reduce management overhead, clarify ownership, and increase organizational throughput.

Technical Due Diligence

Investor-grade assessment of engineering, product, and AI readiness for M&A and fundraising.

AI Workflow Transformation

Redesign how teams plan, build, and operate using AI-native workflows, not bolt-on tools.

AI operating systems

Execution infrastructure, not AI theater.

Internal AI systems designed to reduce coordination overhead, accelerate execution, and improve organizational throughput. Not gimmicky agents or autonomous employee replacements. Operational leverage built into how the company runs.

Engineering workflows

AI-assisted development, review, and delivery systems.

Product operations

Roadmap coordination, spec generation, and decision support.

Knowledge systems

Institutional memory that compounds instead of fragmenting.

Operational automation

Coordination tasks removed from human bottlenecks.

GTM & content systems

AI-native growth and content operating systems: distribution infrastructure, not content services.

Selected work

What I have built and led.

Companies, platforms, and execution environments I have co-founded, scaled, or helped redesign. Each reflects a specific operational challenge and the work required to move it forward.

The through-line across these engagements is consistent: improve how organizations execute, integrate AI into real workflows, and build infrastructure that compounds rather than decays under scale.

Founder Outcome

Co-Founder & CTO: Scale Through ~$50M Acquisition

Co-founded and scaled a company as co-founder and CTO through a successful ~$50M acquisition, with operator credibility earned by building and exiting from the inside.

Co-founded and served as CTO of a software company from inception through a ~$50M acquisition, building execution systems, product discipline, and operational infrastructure that created durable enterprise value.

Execution Infrastructure

AI-Native Organizational Execution Platform

AI-native execution infrastructure designed to embed durable AI workers directly into how teams plan, build, and operate: inside work, not adjacent to it.

AI-native execution infrastructure embedding persistent AI participants into product, engineering, and operational workflows, compressing coordination and increasing organizational throughput.

  • Coordination compression
  • Workflow orchestration
  • AI-native operations
  • Execution acceleration

Growth Infrastructure

AI-Native Growth & Content Operating System

Operational content infrastructure designed to scale distribution, compress GTM coordination overhead, and embed AI directly into acquisition workflows.

A vertically integrated operational platform where fulfillment, content, SEO, paid media, and workflow orchestration functioned as one coordinated execution layer: GTM infrastructure, not a content agency.

  • GTM orchestration
  • Content throughput
  • SEO systems
  • Operational leverage

Regulated Operations

Workflow-Native Financial Operations Platform

Durable workflow infrastructure for regulated environments, integrating human-in-the-loop AI participation without compromising operational reliability.

AI-assisted operational workflows embedded inside a compliance-critical financial platform, where reliability, orchestration, and human judgment must coexist.

  • Compliance orchestration
  • Human-in-the-loop AI
  • Workflow-native architecture
  • Operational reliability

Infrastructure

Multi-Tenant AI Infrastructure Platform

Durable multi-tenant infrastructure for AI execution, designed for reliability, isolation, and operational scale rather than demo-grade deployments.

Multi-region execution infrastructure supporting durable AI workloads, tenant isolation, and operational reliability at scale. Foundational proof of technical and systems depth.

  • Multi-region scale
  • Tenant isolation
  • Execution reliability
  • Infrastructure maturity
Read case study

As co-founder and CTO, led a company through a successful ~$50M acquisition. Since then, has built AI-native systems spanning engineering, product, and GTM, bridging technical depth with distribution and operational sophistication.

Insights

Thinking on execution, AI leverage, and technical leadership.

AI Systems

AI Operational Leverage

Why most AI initiatives fail to change how companies execute, and what actually creates leverage.

I work with a limited number of companies at a time.

Typically partnering with funded startups and growth-stage companies navigating scale, technical leadership challenges, or AI transformation.
