$1.5B founder explains AI’s job shifts and founder playbook

Decagon builds conversational AI agents for large brands, automating customer support interactions across chat and phone while integrating with customer data and taking actions like bookings.

Zhang frames AI’s impact in three company modes: growth amplification, experience/quality improvement, and cost savings (often reducing outsourced agencies rather than internal headcount).

He argues job “extinction” is less about disappearing work and more about tasks shifting from direct output (e.g., pure copywriting) to supervising, designing, and improving AI—creating roles like “conversation/AI architect.”

For builders and candidates, he emphasizes customer-driven idea discovery, revenue as the clearest B2B signal, and two standout traits for the AI era: analytical thinking and strong communication (to instruct and debug AI).

Key Takeaways

AI adoption splits into three buyer archetypes.

Zhang sees customers using AI agents to (1) scale faster without proportional hiring, (2) improve customer experience regardless of cost, or (3) cut costs—often by downsizing outsourced agencies first.

The most threatened jobs are “straight output” roles.

If a role’s value is primarily producing text or other standardized outputs (e. ...

Work doesn’t vanish; it moves up the complexity ladder.

Tier-1 repetitive interactions (password resets, basic booking changes) get automated, while humans shift to tier-2/3 cases, relationship management, and AI oversight such as QA, data collection, and escalation handling.

A new career path is emerging: conversation/AI architect.

Companies need people who can design agent behavior, review failure cases, and iteratively improve instructions and knowledge—often evolving from CX managers, knowledge-base owners, or chatbot managers.

Analytical reasoning is a core “AI-era” employability skill.

To improve an agent, operators must break down a bad conversation into steps, inspect reasoning/knowledge/tool use, and propose precise changes—essentially debugging workflows rather than just handling tickets.

Clear communication becomes a technical advantage even for non-engineers.

Decagon trains users to “teach” agents in plain English; ambiguous or contradictory instructions degrade performance, so writing crisp, consistent guidance becomes a high-leverage skill.

For AI startup ideas, customer discovery + willingness-to-pay beats building first.

Zhang recommends gathering signal early by deeply understanding ROI, budgets, and decision processes; in B2B, revenue (or credible price anchoring and commitment) is the strongest validation.

Notable Quotes

For people with non-technical backgrounds that want to get into it, I think right now is a golden time.

Jesse Zhang

There’s no sort of… need anymore for someone that just writes the copy.

Jesse Zhang

Humans kind of… [become] guiding that technology.

Jesse Zhang

Everything is about really getting signal on what to build and what’s useful… in B2B… the purest signal is… are you getting revenue?

Jesse Zhang

You have to find your own way… it’s actually super easy to over-index on what other people have done.

What do you think are the jobs that have the highest risk of extinction?

Jobs where [beep]

Marina Mogilko

Meet Jesse Zhang, twenty-seven years old and already co-founder of a $1.5 billion AI company. His startup, Decagon, powers conversations for brands like Hertz, Duolingo, and Notion. In just two years, his team has grown to nearly two hundred, so he is hiring. But the question is, how and who? You're seeing some of the companies actually laying off agencies that they're using, right? What do you feel like the percentage of these companies is?

Jesse Zhang

Within those categories that I listed, maybe one-third, one-third, one-third.

Marina Mogilko

So it is happening, and you see it. In this episode, we explore the future of work, from the jobs most at risk in the AI era, and we're gonna talk about new career paths that are opening up and the skills that will define the next generation of leaders.

Jesse Zhang

For people with non-technical backgrounds that want to get into it, I think right now is a golden time.

Marina Mogilko

And when you interview people for a company, can you name some skills that you're looking for? Welcome to Silicon Valley Girl, everyone. Jesse, you founded a company that helps corporations build AI agents to automate processes inside those corporations, and one of your customers said working with you is like having sixty-five people working on a particular pro- problem. Do you see it as creating more opportunities or, like, taking jobs from people who were doing these tasks?

Jesse Zhang

Yeah, no, hap- happy to give some context. So you mentioned kinda using AI agents to automate things. We, we focus specifically on conversations with end users, right? So as an example, let's say, uh, you know, we work with a hotel chain, and as you can imagine, a lot of the customers that go and stay in the hotels and, and so on, they'll have a lot of inquiries, like, "I wanna book a room," or, "I want to upgrade my room," or, "I have questions about my loyalty points." Um, these are classic... You know, you can think of these as customer service or customer support inquiries that come in, and the AI agent's job is to have a conversation with them. This can be over the phone. It can be over live chat, and the AI agent can have the full conversation. It might need to go look up information about you, right? It might need to figure out, like, what are your past stays, or it might need to figure out, like, what loyalty tier you are. So it might- it can go in and look up information. It can take actions as well, so it can go and, and book a room for you, and, and so on. So in a nutshell, that's what we do, and so those are the... You know, you mentioned automating processes.

Marina Mogilko

Mm-hmm.

Jesse Zhang

That's, that's kinda what we do. Uh, it's, it's more about automating these conversations. Um, so back to your question about how we view the innovation, the, the, and sort of impact on these organizations. It really depends on what the organization is looking to get out of, get out of AI agents, and different organizations are in different stages. Uh, some people are in heavy growth mode, right? So the AI agent is more of an amplification of what they currently do. There's, there's no one that's replacing per se, but it's, it's making, it's making their operation just much faster and, and making it so that it's a lot less operationally intensive for them to grow, right? If they grew five X in the last year, maybe they don't need to, you know, five X their support team. So that, that's one, uh, thing that we see. Other organizations that we talk to are more focused on, um, the quality of the experience. Maybe they just don't care about cost, so they don't really care how many... Uh, they're not, you know, replacing anyone. They're, they're more just kind of like, "Okay, we think that having the AI agent here will make the customers a lot happier with us because, you know, they can get answers instantly. They can get what they wanted, you know, within a few seconds, rather than waiting on hold." And so that's what we're seeing, and th- those are kind of different profiles. And, of course, there is also a third, uh, category of company, where maybe they're just in cost-saving mode, and so what they're using AI for is kind of, you know, making their operations more efficient and, uh, either reassigning those folks to other, uh, jobs or, more realistically, sometimes they're using, like, outsourced, um, you know, agencies, and they can downsize those, right?
