Scrappy Then, Strategic Now: The Evolution of a Cybersecurity CMO
Most first marketers don’t stay long enough to see scale. Thomas LeDuc did. Six years in, he’s still at Semperis, leading a 35-person marketing team and showing it’s possible to evolve from scrappy to strategic.
Gianna and Charles explore what makes that kind of longevity possible: the mindset shifts, the habits that stuck, and the moments that nearly broke him. This episode is full of clarity, honesty, and the kind of leadership most people don’t talk about.
You’ll hear:
This one will land if you’ve ever had to scale yourself while scaling a team.

About Tom:
Tom LeDuc joined Semperis in 2019 as a scrappy marketer and helped scale the company from a few million ARR to now more than $100M ARR, reaching “centaur status” in 2024. Today, he leads a 35-person team as CMO, overseeing everything from brand and product marketing to demand gen, field programs, and built out the SDR program.
Before Semperis, he held leadership roles at Verodin (acquired by FireEye). He got his start in cybersecurity as a BDR at Securonix and played a big role in building several categories you’ve probably seen on Gartner quadrants.
Outside work, Tom is a dad of two young kiddos, makes indie films, travels a lot, and is very pro-dog.
