How Duo Security went Zero to $1B ARR in Ann Arbor | Dug Song, Jon Oberheide
The Peel with Turner Novak
What Changed Inside Cisco After Acquisition
They reflect on challenges: customer proximity, long sales cycles, and leveraging Cisco's massive go‑to‑market.
Dug Song and Jon Oberheide are the co-founders of Duo Security.
If you’ve never heard of Duo, it might be one of the most underrated software stories of all-time.
Starting in 2010, they burned only $14 million to hit $100m in ARR, were acquired by Cisco for $2.35 billion in 2018, and now rumored to be doing over $1 billion in ARR inside Cisco 16 years later.
We talk about how they built one of the most capital efficient SaaS companies ever from Ann Arbor, Michigan, and how their focus on the customer and company culture helped them win in a crowded cybersecurity market.
We talk growing up in the early hacking culture of the 90s, why most security tools are painful to use, sizing their market, solving for non-consumption of a product, and how Duo flipped the model by designing for end users instead of security teams.
We talk about staying in Michigan instead of moving to Silicon Valley, and why staying out of the tech bubble helped them execute.
We break down the mechanics of scaling from zero to $100 million in ARR, everything they learned integrating with Cisco, and why more founders should build outside of San Francisco.
A quick thank you ex-Duo employees Zack Urlocker, Ash Devata, and Katie Kilroy for their help brainstorming topics for the conversation.
