When Tony Stubblebine took over as CEO of Medium in 2022, the platform was burning $2.5 million a month, bleeding subscribers, and was overrun with content that left founder Evan Williams cringing. 

Tony pitched Ev a turnaround built on small teams with access to data, customers, and the freedom to rebuild Medium like a startup from the inside out.

He wasn’t just another executive parachuting in — Tony had worked with him as head of engineering, later as a power user and publishing partner, and eventually, the person who convinced Ev that he could get things on track.

In this episode of Fund/Build/Scale, Tony explains how Medium became profitable for the first time, why the platform banned AI-generated content from its partner program, and how his long history as a user and advisor uniquely prepared him to lead the company through a delicate transformation.

(3:41) “ I have a long track record of being associated with Medium for just strange reasons.”

(7:16) “ Maybe I'm crazy, but I thought on day one, ‘oh, this is a guaranteed win.’”

(9:52) “ I think CEOs are delusional, and some amount of delusion is probably healthy.”

(12:34) “ Precision is not possible without a combination of data science and user research or words.”

(14:30) Creating customer feedback loops in a 13-year-old company

(19:49) “ I would almost say there's no product to manage yet because we’re making it, and we’re making it together.”

(20:17) The two mandates Evan Williams gave Tony when he hired him as CEO

(24:23) “I  knew even if we could grow subscribers, it would be on the back of this content that we weren't proud of.”

(25:45) Why Medium banned AI-generated content from its partner program: “ We're a pro-human product.”

(30:11) “ We love human moderation. We love our trust and safety team.”

(36:28) “ We're trying to be a place where a different set of writers will win on Medium than will win on these other platforms.”

(40:46) “ One hundred percent: Medium is for experience, not for influencers.”

(42:35) “ I really like to be a champion for what I would call ‘white hat content marketing.’”

(46:45) “ It's wild to me that the art of blogging has not been perfected this many decades into it.”

(48:17) “ It's impossible to understand how many niches there are.”

What makes a founder dangerous?

Not credentials. Not their pedigree. And it's not who they know.

What kind of founder spends five years building a product before going to market?

One who's trying to solve a very hard problem.

Vince Gaydarzhiev is the founder of Alcatraz, a deep tech startup that uses facial authentication. The platform isn’t used to lock people out of single offices or consumer gadgets; its customers are buying global enterprise security, where compliance is strict, trust is earned, and failure isn't an option.

In this episode, Vince shares the emotional, strategic, and technical realities of building a company at the intersection of AI, hardware, and enterprise infrastructure. From working nights on prototypes with a tiny team to navigating founder isolation and breaking into risk-averse markets with no Silicon Valley network, Vince takes us inside the long game of building something real.

We cover:

If you're building something technically ambitious or thinking about launching a startup in AI, hardware, or security, listen in.

(2:35) Where the idea for Alcatraz came from and why Vince decided to take the leap

(5:51) His process for validating the concept with investors, customers, and security teams

(9:37) “I  was surprised that this thing didn't exist yet.”

(11:48) Why it took five years to develop a “globally scalable” minimum viable product

(13:29) How much has his TAM estimate changed since entering the market?

(17:55) The pitch Vince used to recruit employees away from Apple and other top companies

(20:05) “ In 2016, investors were investing into companies purely on a deck.”

(22:18) “ I had zero network. It was my first time.”

(24:42) “ Many people mentally cannot take ‘nos’ in bulk. They get depressed, they feel it's personal.”

(26:50) Why the name “Alcatraz?”

(28:12) “ It's really tough to work with people that you don't like. Very tough. It's never gonna work out.”

(30:24) The one question Vince would have to ask the CEO if he were interviewing at an early-stage startup
