In the heart of the historic working-class and Latino Mission district in San Francisco, the door of a ground-floor unit next to a trendy coffee shop keeps opening. A private shuttle that ferries tech workers to their Silicon Valley headquarters farther south passes by every morning. The 796 sq.ft. (74-square-meter) apartment, recently renovated and furnished, is thoughtfully laid out, from the small open kitchen to the built-in closets. But it gets very little light. Of its two bedrooms, one has no windows. And it costs $4,750 a month.

This as-told-to essay is based on a conversation with Bridget Griswold, the 25-year-old CEO of Lean In, who lives in San Francisco. It's been edited for length and clarity.

I fell in love with technology at Brown University, where I studied computer science and business. I worked with two female professors to build a robot. I interned at a semiconductor manufacturing company and also loved design and art.

Product management felt like a really wonderful combination of all those interests, and that was my role at Meta a year after graduating from college. My team and I redesigned the Instagram search grid, so now when you search for large Instagram accounts, you're routed to the search results page rather than directly to those accounts. I'm very proud of that.

While at Meta, an incredible female mentor connected me to Sheryl Sandberg. Meeting her felt so surreal and is what led me to start my role as CEO at Lean In in March. It feels like a once-in-a-lifetime opportunity to do mission-driven work.

I was a swimmer as a kid, and as my swim coach used to say: "You get out of swimming what you put into it." I think that applies to many things in life: The more you put in, the more you get out.

Here's a day in my life.

I wake up to my needy, angelic cat around 7:30 a.m.

The second I wake up, I pet my crying and whining cat. She's an angel but very needy.

I'm not a breakfast person, but I need coffee immediately. I have many cups of coffee throughout the day. One of the first things I do is make some at home.

I always tidy up my apartment while brushing my teeth

The most productive two minutes of my day are when I brush my teeth. I clean and tidy my apartment at the same time.

I'm probably not super focused on brushing my teeth, which is maybe a problem, but I'm also making my bed, emptying the dishwasher, feeding my cat, or starting the coffee maker.

I always move really quickly; I don't like to sit still. Brushing my teeth and standing still would make me antsy, so I like to get something else done at the same time.

I'm still adjusting to West Coast hours

I moved from New York City to San Francisco in August.

In New York, I went to Solidcore classes before work every day. Working on the West Coast, the workday starts earlier than on the East Coast, so I'm still learning whether I like to work out in the morning or after work.

When I take the bus to the office three days a week, I often use that time to catch up on personal housekeeping tasks like scheduling appointments or texting back my friends who live on the East Coast.

I come to the office around 8 a.m. or 8:30 a.m.

A majority of my in-person time is spent in meetings. As CEO, I enjoy being involved in all aspects of the team.

I'll meet with our content and research team — we spend a lot of time digging into data, such as some really exciting new research on trad wives in the manosphere. I also often meet with our product and tech team, as well as many of our partners, to help grow our programs.

We have lunch in the office — my favorite is a salad-plus-smoothie combo — and it's a really wonderful time to connect with the team.

I also love connecting with our Lean In community. One thing we're focused on is closing early gender gaps in AI usage. Our flagship program, Circles, consists of groups of 8 to 12 women who meet regularly to support each other in their careers — we have over 170,000 members. It's a perfect forum to hold each other accountable for upskilling in AI.

Every week, I send AI tips to our network leaders. A recent one encouraged the use of AI notetakers, as women are more likely to take notes during meetings and miss out on participating.

Lean In is in over 180 countries, and it's really heartwarming to see that our commitment to our mission has a positive impact on women's careers. Getting to speak with them is really energizing and rewarding.

I rehearse for meetings by talking to myself on walks

Another habit of mine I've been told is weird is how I prepare for big meetings.

If I have a presentation or interview coming up, I'll set up a Zoom and practice speaking to myself. Talking for a long time is sort of an unnatural act, and the first time you do it is probably not going to be your best.

Sometimes, I'll even go on a walk and wear headphones, pretending like I'm in a meeting or on a phone call, but I'm actually talking to myself and practicing.

When there's a bug, I usually fix the code myself

Because of my background in computer science, I spend a lot of my time finding bugs or things I believe we should change on our platform. I'll code and fix those on my own. Thankfully, with AI, it's so much faster to code now than it was a few years ago.

Our team is busy, and my goal is to enable everyone to have as much impact and move as quickly as possible. If I can help unblock the tech team or resolve an issue rather than add it to their plate, I'm always more than happy to do so.

I leave work around 6 p.m.

I continue to work until I go to bed pretty much every night.

It's nice to have that time at home, when I'm not running around between meetings, to focus, give feedback on documents the team has sent, write, respond to emails, and brainstorm my own ideas.

I take breaks to tidy up my apartment and make dinner. Living in New York got me out of the habit of cooking, so I'm taking the initiative to cook more meals, like rice bowls. I would say about half the time I order takeout, like pho, and the other half I cook, which is progress for me.

If my work doesn't require intense focus, I'll do it from the couch and put a happy TV show on, which right now is "Schitt's Creek." I think it's a nice balance between relaxation and getting things done.

I usually get in bed around 10:30 p.m.

I've been trying to make a habit of reading every night instead of going on my phone, which has been a really positive change. I like anything I read to be a distraction. I'm currently reading "Big Little Lies" and enjoying it.

It's nice to spend 30 minutes reading something like fantasy that's completely different from what I think about at work. That way, I'm not spinning on all the things I need to do or coming up with new ideas that can't get done in my sleep anyway.

Weekends are for the beach and farmers market

My boyfriend works in Los Angeles and flies up to San Francisco every weekend. We've made a tradition of going to the Fort Mason Farmers Market on Sundays for fresh produce to cook an at-home meal that night.

I also enjoy seeing friends over the weekend. My preference is to go on a long walk or go to the beach. I also enjoy fitting in some work — emails, deep-focus work, or reading — throughout the weekend.

• A sign instructing San Francisco gym-goers not to vibe code between sets went viral.
• The sign was an "AI-generated fake," according to the gym.
• Amid tech's vibe-coding obsession and fitness boom, it's no surprise the image has gotten heat.

Don't hog the leg press while prompting Claude.

A screen with the logo of Fitness SF, a Bay Area chain of gyms, went viral among techies on X and Instagram on Monday. The image instructed gym-goers to refrain from writing code or prompting AI during their workouts. "Be present. Lift harder. Ship later," the image reads.

Troy Macfarland, Fitness SF's director of marketing, said, however, that the image was an "AI-generated fake." The gym does have etiquette signs that mention phone usage and being courteous, he wrote, but none mention vibe coding.

"This person altered our actual images displayed on the screen," Macfarland wrote. "I will give an 'A' for creativity to him."

It's not clear whether the image was generated with AI, Photoshop, or some other tool. Ian Brash, whose post with the image got almost 7,000 likes, did not respond to a request for comment.

In San Francisco's AI mania, it's no surprise a sign like that blew up on X. Techies weighed in, cracking their own jokes about how tied they were to their coding agents.

One X user told Fitness SF to give their copywriter a raise. A Cognition engineer said that vibe coding between sets was encouraged at his company's gym.

"Vibe coding at the gym?" one X user wrote. "You're worried about the wrong weights."

One reaction image often appears in the comment sections of posts like this one. It shows a muscled man, holding a giant nuclear bomb in his hands, jumping into the city of San Francisco. One VC posted it with the message: "Even I have limits."

Claude Code and cardio

The sign tapped into two of the buzziest subcultures in tech.

First, there's AI coding. Ever since the launch of Claude Code and OpenAI's Codex, engineers have been tied to their phones (or walking around with half-open laptops) to continue building. Some techies told Business Insider that their love of vibe coding created distance between them and their girlfriends.

Then there's the gym. Tech bros are getting fit, pumping themselves full of peptides and getting shredded at early-morning Equinox sessions. A developer at the gym used to be an anomaly; now, it's the norm.

Some techies seemed skeptical from the start. One X user quoted the post, writing that there was "no way this is real."

Another user responded that they didn't know about that specific sign, but they did know about the underlying issue. "This is a real problem at the Equinox in San Francisco," they wrote.

Exclusive: Nvidia, Microsoft and Cisco taskforce urges ministers to offer areas greater benefits from tech infrastructure amid fears of US-style opposition

AI companies have told ministers they have 12 months to head off public opposition to datacentres in the UK or risk US-style protests that could threaten their construction.

Successive dry summers and rising energy bills are increasing public scrutiny of plans for the huge computer warehouses that are used to train and run AI models, says a submission to the Labour government from a group including the AI infrastructure companies Nvidia, Microsoft and Cisco.
