In startups, pivots are not tweaks. They are the moments when everything built so far gets questioned, and the founder decides whether to keep going as is or to risk it all on a new path.

The Social Radars is a podcast hosted by Jessica Livingston, co-founder of Y Combinator and author of Founders at Work, and Carolynn Levy, YC’s Chief Legal Officer,. In their Founder Mode series, they explore the choices that define a founder’s path.

On one of those episodes, Jake Heller, co-founder of Casetext, spoke about the weekend that changed everything for his company. After almost ten years of building AI tools for lawyers, he and his co-founder were given early access to a pre-release version of GPT-4. They stayed up the whole weekend testing it. “We had to pivot the business,” Jake said on The Social Radars, “change everything we were doing for the last nine and a half years.”

The conversation shows why that call mattered, how earlier models had failed lawyers with “plausible nonsense,” why GPT-4 felt like the missing piece, and how conviction turned into momentum. Within months, Casetext doubled nine years of revenue and was acquired by Thomson Reuters for $650 million.

Jake also shared stories from much earlier: growing up in Sunnyvale, learning to code in the garage with his dad, watching him build one of the first internet companies in the ’90s. He spoke about trying to code software inside a big law firm only to be told the firm owned it, the push that forced him to leave and start Casetext. He remembered Sam Altman’s blunt YC feedback, “that’s not fast enough”, and why it was exactly what he needed to hear. He talked about testing GPT-3 and GPT-3.5, dismissing them as unusable, then seeing GPT-4 score in the 90th percentile on the bar exam. He recalled the split reaction inside his own team, how he went back into “founder mode,” coding again and experimenting with prompt engineering, and finally, how before the acquisition he printed out an Excel sheet showing what the payout would mean for each employee, a reminder of how decisions ripple across people’s lives.

Some interesting segments from this Social Radars conversation:

> Growing up in Sunnyvale, coding with his dad instead of playing catch.
> His dad, a high-school dropout, building one of the first internet businesses in a garage.
> Building tools inside a big law firm, only to be told the firm owned them.
> Leaving law to start Casetext after that push.
> Sam Altman’s YC feedback: “that’s not fast enough.”
> GPT-3 and GPT-3.5 dismissed as “plausible nonsense.”
> GPT-4 suddenly scoring in the 90th percentile on the bar exam.
> A team divided, half excited, half tired of another pivot.
> Jake going back into founder mode, coding and hacking prompts before the term existed.
> Printing out an Excel sheet of payouts before the acquisition, realizing how life-changing it would be for long-time employees.

When you hear it in his words, it’s clear why this story sits in the Founder Mode series. The pivot didn’t just change Casetext’s roadmap. It changed the company’s pace, its people, and even the founder himself. That is what it looks like when a pivot truly changes everything.

I first met Kasish Yadav in Ahmedabad during one of our Founders Heritage Walks. She was in town for another program but decided to join in. As we walked through the old city lanes, she said, “I want to build something like this in my city.”

At the time, eChai Jaipur wasn’t very frequent. That walk planted a thought, and over the next few months Kasish began to shape it in her own way.

She started hosting panels, putting together founder meetups, and curating spaces where conversations could flow. Some gatherings were formal, with speakers and sessions. Others were dinners at her place, where strangers slowly became friends. Alongside what she was leading, she also joined other groups, women founder circles, local meetups, WhatsApp communities. Some days she was the host. Some days she was just another founder in the room.

That’s how you find your tribe. You don’t wait for it to appear. You show up. You host. You join. You add your energy wherever you can. Slowly, the circles stitch together, and the city that once felt unfamiliar begins to feel like home.

For Kasish, that’s what Jaipur became. Not just a place she moved to, but a place she belonged.

Radhika’s work begins with listening. Every part of what she does, the Elevate sessions that feel like conversations with a friend, the fortnightly check-ins in her relationship coaching, the confidential introductions on WhatsApp and Zoom, the sober curious parties where strangers meet without the crutch of alcohol, rests on how deeply she hears people. What starts as a short call often turns into a space where people share family pressures, past relationships, or the quiet loneliness of being misunderstood.

As a matchmaker, relationship coach, and social health advocate, her work is about creating spaces for meaningful connections, one-on-one, in small groups, and through personal introductions, where people feel safe to open up and build relationships that last. She often says, “I strongly believe that the quality of our questions defines the quality of our conversations which then defines the quality of our relationships and therefore life. Let's start with being kind and curious, asking good questions and truly listening.” That belief runs through everything she designs, from intimate conversations to larger gatherings.

Her business is built around this practice. The introductions matter because the stories behind them are understood. The coaching works because the check-ins reflect what people genuinely feel. The gatherings leave a mark because people sense they can be themselves without pretense.

It leaves behind questions that linger: In our rush to move fast, how often do we pause to listen? What shifts in our work when we treat listening as the center? And as founders, when was the last time we created space where someone could speak freely?

Startup life is filled with notifications. Emails, calls, group chats, bank alerts, they come all day, every day. Most are routine, but a few stand out. These are the ones that make founders smile.

Some are about connections. A reply from a founder you admire. A mentor agreeing to a quick chat. Or a friend from long ago sending a message of encouragement. They may not show up in your metrics, but they change the way the day feels.

Others are about the product. A new customer signing up from a city you’ve never visited. A review that says, we use this every day. Or a photo of your product spotted out in the world. Each one is a reminder that what you’re building is reaching people.

There are also the team moments. A tough bug closed. A long-awaited feature shipped. A late-night Slack message that simply says done. And the practical relief of seeing the payroll notification, salaries paid, on time. Each one carries more weight than the task itself; it’s proof the company is moving forward together.

And then there’s the timeless one: payment received. It never loses its magic. More than money, it’s belief turned real. Among all the notifications, this is the one that makes every founder smile.

As part of The First Welcome in Silicon Valley series, I have been asking founder friends to share their stories of the first welcome they experienced in Silicon Valley. These are the people, the moments, and the gestures that stayed with them.

In this stream, Mala Ramakrishnan, Founder and Managing Partner at Progressive Ventures, shared memories from her earliest days at Stanford. With more than 20 years of operating experience and a deep focus on actionable insights for B2B AI SaaS, Mala has built her career on technology and people, and her first welcomes in the Valley reflect both.

"My first job as a grad student, was driving a golf cart around Stanford campus installing computers in the undergrad dorm rooms. I don't remember the name of the staff who hired me, just his face... and I was ecstatic - driving a golf cart before I was eligible for a driver's license, earning $12 an hour, and doing the thing I loved most in the world at the time - installing computers.

The two people who touched my life most, were Anand Chandrasekaran (who we affectionately call AK) and Dan Turchin, who invited me to write a business plan that got first place from Guy Kawasaki and got me on stage and published in some famous magazines.

The prof who was kindest and I learnt the most from, was Prof Leonidas Guibas who taught Data Structures and Algorithms and kindly let me be his TA for a few quarters, which covered my tuition and helped me truly understand data structures and algorithms that I can clearly explain them even today, after 25 years. He even took us out to eat Indian food in Amber India at the end of the quarter for working in his class. Amber Los Altos is still my favorite Indian restaurant from those memories."

Mala’s story shows that the first welcome can come in many forms. A job, a mentor, a professor’s kindness, even a shared meal that becomes a lifelong memory. These are the moments that stay with us and remind us that the Valley is not only about companies being built. It is also about people creating belonging for each other.
