About Aaron Jacobson

Head of B2B Growth Marketing at SpaceXSI (formerly X)

I’m a growth marketing and product leader with 11 years in marketing and product and 7 in finance and analytics, at startups and large companies.

Today I lead B2B growth marketing at SpaceXSI, formed when X merged with xAI and was acquired by SpaceX. The goal is to grow B2B actives and revenue, profitably, across lifecycle, paid media, and the web. I managed two direct reports for over a year. The org is now flat, and I work with ads engineering, data, product, sales, finance, and design. Scope, results, and how I use AI →

Programs I’ve led or been part of have driven over $1B in profit impact. I’ve also founded small businesses and worked on economics and product strategy for blockchain startups. I do my best work building something new or making an existing system faster and simpler.
