Doug Tallmadge spent five years helping build Starlink at SpaceX. Now he builds AI agents for marketing teams. To him, the leap from aerospace engineering to marketing wasn’t much of a leap at all.
A rocket launch and a marketing launch both begin with an ambitious idea that has to survive an enormous amount of coordination. There are deadlines, dependencies and dozens of people responsible for getting one small piece exactly right. And somewhere in the middle of both is a spreadsheet trying to hold the whole thing together.
Doug saw that overlap while helping grow Starlink’s beta program from its first 50 users to its first half-million. His job extended well beyond engineering as the team worked through regulatory approvals, hardware inventory and customer communication. In Starlink’s earliest days, Doug personally emailed some of its first users.
So when ChatGPT arrived in November 2022, Doug wasn’t only interested in what AI could build. He was interested in whether it could help large teams get complicated work out the door faster. He and his co-founders incorporated a company within days, quit their jobs and began testing AI agents across different parts of the enterprise.
Marketing wasn’t the original plan. It was where they found the greatest urgency.
One large aerospace company told Doug that Gradial’s technology could save tens of thousands of hours a year, but adopting it still felt too risky. Marketing teams had the opposite response. They wanted to know whether Gradial could integrate over the weekend.
That was the signal. Gradial was only five people, with paying customers and promising opportunities in several directions. The team chose marketing because those customers weren’t discussing what AI might eventually do. They already had work piling up and wanted help doing it.
Doug may have traded rocket launches for marketing launches, but the problem that interests him hasn’t changed much. He’s still trying to move something complicated from an idea into execution.
Conversation Nibbles
An appetizer before the entrée
Rocket launches and marketing launches have a lot in common: Both rely on a clear vision, coordinated teams, detailed checklists and exact execution.
Urgency tells you more than interest: An aerospace company saw Gradial’s value but resisted the risk. Marketing teams wanted it running immediately.
A promising opportunity can still be a distraction: Gradial had paying customers across the enterprise, but a five-person team couldn’t build in every direction.
Your calendar should keep changing: Doug believes a founder’s job changes every three to six months, and their time should change with it.
Fundraising eventually becomes less about the founder: Early investors buy into the team and its vision. Later-stage investors need momentum.
Founder advice: Change your mind quickly when the information changes, without letting ego slow you down.
