I'm Rob Weidner. Fractional CTO.
Always finding a better way.
I'm a Fractional CTO based in Austin, Texas, working with founder-led service businesses. I join your leadership team as a part-time CTO, with clear ownership of the technology decisions behind one priority initiative. I set direction, coordinate your builders and vendors, and measure what changes in the business.
“It's fun to take a step back and rip the Band-Aids off the systems and put stuff in that we know will be here for a long time. It's fun to just see it keep growing each week now with you.”
— Zach Dulla, CEO, Indoor Drone Tours
Worked with: a Fortune 100 technology company, a Fortune 100 automaker, two large energy utilities, two of the world's largest philanthropic foundations, and founder-led operators like Indoor Drone Tours, plus Disney, Marvel, Apple TV+, Rivian, and Porsche on the production side.
Some of this work was delivered through agency partners: Claribase, Optimize, and Pretty Simple.
What fractional means here
A fractional CTO is a part-time, fully embedded technology leader. I take responsibility for the agreed technology decisions and help your team carry them through, with scope and availability defined at the start. (Fractional Defined)
What ownership means
- Stack and vendor decisions you can defend
- AI with clear data boundaries
- One profit-linked operating loop with a baseline and a 90-day result
- Your builders still build; I own decisions, adoption, and measurement
Who this is for
Founder-led service businesses (~30–250 people / $10M–$75M) where revenue or tech spend is rising faster than profit.
