Hi. I'm Nate Marcus
I build AI products. This site is one of them.
Ask the agent about my work experience, or drop in a JD (URL or PDF) to understand my suitability for a role and to draft a tailored cover letter.
By using this chat, you consent to have your messages stored for up to 30 days so Nate can review agent behavior and construct evals. Data collected in this way is never used for marketing or solicitation.
About
Context is king.
I'm an AI-pilled product leader with ten-plus years finding opportunity and driving growth across enterprise SaaS and retail e-commerce. I have hands-on experience with production agentic products, DX tooling & PLG pipelines.
Today I lead product and ops at Superpilot, where we're building the first AI-native platform for e-commerce marketing teams. Before that I was a product director at Salesforce Commerce Cloud.
Before that, I spent nearly nine years at EF Education First — started on the ops side, finished running technology, analytics, and e-commerce. I am a history nerd by schooling who stumbled into technology because it was fun.
I run product with a GM mindset: what drives growth? Customer outcomes and ARR are how I measure success, and I like to stay close to GTM through deal support and post-launch CS.
Above all, I love learning and sticky problems. Give me ownership and space to execute, and I'll figure it out.

In progress Heavy Weighs the Crown
2D Unity game expanding on the LLM-as-NPC concept. The player is the newly crowned king. You have a council of 5 LLM advisors - one is trying to depose you...
- Unity Engine
- Game Design
- Agent personas
In progress agent-box
Siri is meh... so I made my own agent running on a local LLM box I built by hand. A privacy-hardened assistant that answers across my own email + calendar + to-do list and more.

Get in touch
Want to talk?
The fastest way to reach "me" (well, the agent version of me) is the chat at the top of the page — it can answer most questions about my work, talk about my fitness for a job description with you, and produce a tailored cover letter you can pass to a hiring team. It can also schedule a meeting on my calendar if you'd rather talk to the actual human Nate.
Or if you prefer there's always LinkedIn. Send me a DM.
