I build the machine, then I run it.

I'm a builder and operator who uses AI to do the work of a team. Give me a problem in marketing, revenue operations, sales, systems, or software, and I'll ship the thing that solves it.

I founded a company and sold it. Then I ran marketing, RevOps, and sales by myself for a business with five product lines.

"Most marketing leaders at companies our size would take 6 to 9 months to stand up this much infrastructure. You did it in under 4."

Previous client CEO

What I've done

2024 to present Kingsfoil Health

Founder

A health insurance brokerage for startups and small companies, built because the benefits market only ever shows founders one option. We shop across level-funded, partially self-funded, and PEO structures, manage claims year round, and disclose our commissions in writing before anyone signs.

2025 to 2026 Startup Science

Head of Marketing & Sales

Ran the entire marketing function alone across five product lines, then built and led a two-person team. Marketing, revenue operations, sales, and the tooling underneath all of it.

  • Grew organic search impressions 521% in one month, from 16K to 102K. Average position moved from 10.3 to 5.6.
  • Published 170+ SEO articles that outranked Y Combinator, Forbes, and HubSpot on target terms, and earned a #2 ranking on both ChatGPT and Perplexity for the category's core buyer query.
  • Ran all marketing for a Regulation CF community raise that brought in $307,950. Wrote the pitch page, built the investor email drips, ran the webinar program.
  • Built an in-house cold outbound engine sending ~29,700 emails a month across 135 inboxes, with a custom AI personalization layer that replaced a $600+/month tool.
  • Built the paid stack from scratch (roughly 35 Google and 14 LinkedIn campaigns, plus Microsoft, Reddit, Quora, and retargeting) and held 6 to 8% CTR, above benchmark.
  • Built the revenue operations backbone in HubSpot from nothing: pipelines, dashboards, forecasting, a data model per product line. Led the integration of an acquired company into the parent brand.
  • Built custom tools in Claude Code (ad campaign generators, a lead enrichment pipeline, self-sending reports) that replaced paid software and covered the work of extra headcount.
2020 to 2025 The Startup Stack acquired by Startup Science

Founder & CEO

Founded and led a two-sided B2B SaaS marketplace connecting founders with vetted software deals. Grew it to a self-sustaining six-figure business. Bootstrapped, never raised.

  • Grew partnerships from 70 to 250+, including 90+ revenue-share agreements.
  • Coordinated $560K+ in custom SaaS deals and reached $60K ARR as the only full-time employee.
  • Held 1,200+ sales calls at a 90% retention rate.
  • Built a 10,000+ subscriber audience with no paid marketing, and moved the platform from no-code to custom code without the technical debt.
  • Ran every function (sales, ops, finance, product, support) and managed the product through multiple pivots.
2019 to 2020 Everee

Business Development Rep, then Jr. Account Executive

First sales hire at a fintech startup. Built the sales motion from zero: scripts, sequences, templates, reporting.

  • Generated $430K in pipeline (90% outbound) from 89 SAOs, closing $20K ARR.
  • Ran 50+ demos as the highest-performing rep, and built the team's Salesforce reports and funnel dashboard.
  • Built partner-channel relationships that produced 43+ referrals.

My expertise

A fractional CMO, a GTM engineer, or the person who builds the systems underneath both.

Marketing & demand generation
Full-funnel, run end to end. Paid across Google, Microsoft, LinkedIn, Reddit and Quora. SEO and AI-search visibility. Cold outbound at scale. Lifecycle, landing pages, newsletter, content systems.
Revenue operations & attribution
My deepest specialty. HubSpot architecture from scratch, ICP data models, lead scoring and routing, attribution, dashboards, forecasting.
AI systems & tooling
This runs underneath the other five. Custom tools built in Claude Code, agentic workflows, AI-assisted production at volume, and build-versus-buy calls. I have replaced paid software with custom builds where the economics made sense. The same work, set up for a whole company, is Cadence, an AI operating system for startups.
Software & technical building
Full-stack web apps (React, TypeScript, Node), data pipelines in Python handling 1M+ rows, internal knowledge bases with search and auth, and production websites from design through deploy.
Sales leadership & enablement
Carried a quota and managed to one. Pipeline discipline, stage definitions, rep dashboards, forecasting, win/loss loops, sequences and playbooks, clean handoff between sales and marketing.
Operations & systems
SOPs and knowledge bases, so the work isn't trapped in one person's head. Vendor selection and management. Acquisition integration, start to finish.

How I like to work

  1. Diagnostic first. A free marketing diagnostic that finds the highest-value work before anyone commits to a big build.
  2. Build and handoff. I build to a working state and document it, so it runs without me. Durable capability rather than dependency.
  3. Always measurable. Every engagement ties to a measurable outcome where one exists.
  4. Flexible engagements. Fractional leadership, a full-time role, a project build, or hands-on execution. We scope it to the problem and worry about the label later.
