Who I Work With
Funded Startups
You built the product and raised the money. Now you need someone to sell it.
- You have engineers shipping features, but nobody owns distribution
- Every month without a real GTM motion is burning runway
- You need a marketer who builds from zero, not one who "optimizes"

Traditional Businesses
You have been in the game for years. You know AI is changing everything. You just do not have the time or the team to figure it out.
- You keep hearing about AI tools, but nobody has shown you what actually applies to your business
- Your competitors are starting to move faster, and you are not sure why
- You do not need a tech company. You need someone who speaks your language and builds it for you

Services
Marketing
I build and run your entire marketing function. Strategy, positioning, content, outbound, paid, the team to execute it. Whether you need a full GTM launch from scratch or a broken funnel rebuilt, I come in, figure out what is not working, and build what should be.
AI Systems
I automate the complex processes that slow your business down. Outbound pipelines, client onboarding, document processing, lead scoring, internal operations. My own cold email system converts at 10%, three to five times the industry average. That is the kind of system I build for you.
Marketing + AI
Most companies need both, and most consultants only do one. I build the marketing strategy and then automate the execution with AI, while also implementing it across other parts of the business. The result is a system that keeps working when I am not.
