SF IRL - Dec 1st, 2025
A curated newsletter showcasing the top tech & startup events in San Francisco

Hi SF IRL! There's a ton of vibrance and energy coming back into the city and at SF IRL, we are excited to be a part of it. Excited to come with you all with some great events for Issue #172. Hope you had a great Thanksgiving and wishing you an amazing December.
I'm Jonathan, the creator of SF IRL. I've been a Bay Area resident all my life and moved into San Francisco about 4 years ago. My full-time job is at Brex where I meet founders and VCs while trying to create a community in the city. My vision for SF IRL is simple. Showcase the best tech + startup events in SF and to connect all of our builders and investors together. We are a growing community having over 9000+ subscribers. As we keep growing, if you enjoy reading these, please share this with your friends so we can hit 10,000 readers. As always, SF IRL is one of my many side projects. If you like to be involved in helping, please shoot me an email!

Dec 4th, 2025 - Fireside Chat with Jonathan Arena (Co-Founder, New Generation)
Location: San Francisco
Time: 6-8pm
What: Product is changing faster than the job descriptions that used to define it. Designers are shipping end-to-end, engineers are talking to customers, and AI tools are collapsing entire workflows. So what does great product design look like now?
Lightfield is hosting an intimate fireside chat with Jonathan Arena, co-founder of New Generation - the startup building AI-powered storefronts that put “a brain behind every pixel on the web.” Jonathan previously led Consumer Product Design at Patreon, designed core photo + community experiences at Facebook used by billions, led design for the Portal AI hardware OS, and managed design for Cruise’s driverless rider experience.
He’ll be sharing lessons from building beloved consumer products, how AI is reshaping interface design, and what it means to craft products that feel magical in an AI-native world.
I’ve made a form to connect the best founders raising with my list of VCs. If you are a founder raising your next round and want to potentially be featured to investors in the SF IRL network, please fill out this form.
I’m launching a newsletter that will feature the top founders looking to hire, founders looking for their cofounder, and operators that are looking for their next role. If you are interested in being featured, fill this form here.
