The accepted story says the crisis hits at 40, and by 50 people start thinking about retirement. Sagit Lampert flipped the order. At 40 she told her boss she was resigning, and stayed. Only in the decade that followed did she make her career change over 50: from 16 years at Citi to the CEO's chair of an AI startup.

Today she is 52, lives in Ramat Gan "but feels like Tel Aviv", is married and a mother of two teenagers. Two months ago, as she puts it, she had a new baby: AVINA, a young InsurTech startup she leads as CEO.

At 40, She Had Already Resigned

Right when she wanted a change, and had even told her boss she was leaving, Citibank, a bank of 230,000 employees, decided to open its second innovation lab in Israel. "And that opened a new and fascinating world for me," she says. From banking and finance, she moved into learning a new technology field and building initiatives from scratch.

What was built there is a hands-on lesson in open innovation: a development and innovation center for financial technologies, the first accelerator in Israel in the field, international competitions for entrepreneurs, and partnerships with leading organizations. "We built the fintech community from the ground up and basically established the term fintech in Israel."

And the crisis at 40? "It vanished as if it had never been. I was in a euphoria of building, and wasn't thinking about leaving at all. If anything, I felt I was only just starting."

There is a lesson here worth pausing on. Sometimes the answer to burnout is not leaving the organization, but finding the startup inside it. When I asked her at the end of the interview, corporate or startup, she answered: "It depends. There are corporates that encourage internal innovation, and then it's a startup in the safest place there is."

A Golden Cage and Feeling Like a Dinosaur

But even an innovation lab ages. "I left Citibank after 16 years with a sense of having exhausted it, and that I was starting to become a dinosaur inside that organization," she says. "I needed to get out of my comfort zone."

That is the moment a golden cage stops being comfortable. The comfort that keeps good people in place is exactly what she felt she had to get out of.

What makes her story especially honest is that she did not leave with a plan. "Honestly, I didn't really know what I wanted. I didn't plan to be an entrepreneur or self-employed, but I understood I had to do something else." For three years she advised various organizations on business development, and only then decided to join AVINA AI.

And her tip for the Sagit of 40 is short and sharp: "Don't work anywhere for more than 5 years, max!"

Career Change Over 50 and the Advantage of Poise

AVINA offers a smart AI-based insurance agent that knows the insurance world and can renew car policies, run control processes and handle the tasks that weigh on the team. This is exactly where AI takes over manual execution, and human value moves to whoever orchestrates the system and builds trust with clients.

What does a 52-year-old CEO have that a 25-year-old founder doesn't? "I think my advantage over a 25-year-old entrepreneur is the experience and a broad network, but mostly I come with poise, with a feeling that no matter what, things will happen the way they need to happen."

She doesn't pretend to be a serial entrepreneur. "Even though this is the first time I'm leading a startup, knowing the business jargon and the titles I've accumulated over the years help me in meetings with clients and investors." This is where 16 years in a corporation stop being a cage and become an asset. The experience is not erased, it simply gets a new job.

And facing the pace of AI? "The pace of life itself is crazy, with or without AI, and I love that pace. I couldn't have it any other way."

Uncertainty as Fuel, Trance as an Engine

I asked her what the secret is to keeping a junior's hunger while sitting in the CEO's seat. "There is no secret. It's exactly this challenge that keeps me alive. All the ends are open, there's no single right answer, there's so much unknown and uncertainty."

She doesn't dress it up. "It's a crazy roller coaster, and when I was younger I probably wouldn't have been ready to handle it. Sometimes I feel the floor is really falling out from under me." Then comes the sentence that sums up the whole story: "The moment everything is routine and clear, I die inside."

Holding that takes an engine. Hers is a combination that only sounds odd at first glance: "Yoga brings me back to center, sport clears my head, and trance is the place where I'm not responsible for anything and just let my body move. That's the fuel!" In Life ROI terms, this is not a side hobby. It is the part of the equation that makes the price of uncertainty bearable.

What Sagit Is Looking For From the Community

Sagit wants to connect with interesting people in insurance or agentic AI. And she offers something in the other direction too: "I still have connections in many corporates, and if anyone needs an introduction, help or advice, I'd be more than happy to help."

If you work in insurance or agentic AI, or you need a door into a corporation, now is the time to write to her, and to continue the conversation with people like her in the Lost in Y community of managers and founders.
