Coming into this interview I wasn’t even sure what “AI Transformation” was, let alone why so many companies pay for it. Here’s the deal: Tenex, the company founded by Alex Lieberman & Arman Hezarkhani, goes into companies hunting for ways to save or making them money using AI. Once they find that, it becomes a no brainer for companies to hire them to build it. But Tenex does more than AI Transformation. They also run a dev shop where their developers use AI to build super fast for clients. Alex Lieberman and Arman Hezarkhani are the co-founders of Tenex, a company blending high-performance engineering with AI transformation consulting. Their model aligns incentives around output rather than time, helping enterprises and startups build software faster and integrate AI across people, processes, and tools. Together, they’re building what they call the “McKinsey for AI”—a hybrid of dev shop, consultancy, and innovation lab helping companies thrive in the post-AI era.

“Why did you launch yet another voice dictation app?” I asked Dan Shipper, founder of Every. I thought he’d tell me that there was some kind of research that showed people needed another one. Nah. It came down to his team’s taste and personal preference. They just wanted something different. So a single creator on the team built it. AI makes it easier for more people to create apps. So what’s the differentiator? From what I got in this interview — over and over — it’s the creator’s taste. Dan Shipper is the founder and CEO of Every, a hybrid media and software company creating AI-powered tools for productivity and creativity. The company publishes one of the most widely read newsletters on technology and builds products like Monologue (AI dictation), Spiral (AI ghostwriting), and Cora (AI email assistant).

YC President Garry Tan told me the reason is simple: AI transformed software from a “nice to have” into an urgent necessity. “Before it was like, ‘Yeah, I know I need to replace my software.’…Today it’s becoming, ‘Oh. I see a demo. It’s really impressive… I need it right now. When can you start?'” Garry Tan is President and CEO of Y Combinator, the world’s most successful startup accelerator.
