jsdf, LLC is operated by Jason Shah

jsdf, LLC is a software development and consulting company, run by Jason Shah. My main areas of focus are:

  • Building products: I use AI and LLMs to both accelerate and scale development as well as to improve the product offering and user experience.
  • CTO-level consulting: I provide product strategy, roadmap, architecture development, and technical leadership.
  • M&A Technical Due Diligence: I help buyers evaluate the product, process, security posture, and risk behind software, SaaS, and software-enabled services companies.

I spent 14 years as the CTO of Mediafly, an enterprise sales SaaS, as we grew from 9 to 250 employees, and led a team of 100 product, engineering, designers, and contractors there.

We conducted 8 acquisitions during my time, and I was intimately involved in many parts of the acquisition cycle.

I've also helped my wife acquire four dental practices, and help her operate them as interrim COO.

I am a Chicago-area native, and live in Lake View with my wife and two kids.

If you want to reach me, please feel free to contact me, or put time on my calendar.
