Hi, I'm Sib
Since 2018, I've spent most of my time as co-founder and chief product officer of Branch, a venture-backed startup that makes office furniture, work products and ergonomic tools for people and teams. We've helped half a million people and thousands of teams across North America create workspaces that improve productivity and well-being without breaking the bank. Regular side quests include writing, investing, teaching and reading as much as I can. I live in Brooklyn.
Before Branch, I helped incubate new ventures at Redfin, co-founded a community for pre-idea founders figuring out what's next, traveled the world as a digital nomad and wrote a drawer novel about post-scarcity and AI, among other adventures. I graduated from Yale with a BA in Ethics, Politics and Economics.
More about me
Branch
Why build a better office furniture company? We use our desk, chair and office accessories for more hours than most products in our lives. Beyond the value of thoughtful design in objects we use every day, choosing the right chair and desk—and using them the right way—has a tremendous impact on our well-being.
Our mission at Branch has two phases. The first phase is launching a complete line of inspiring office products to make a great day of work more accessible to everyone. The second phase is pairing physical and digital experiences to radically expand the ways in which a workspace can support productivity and well-being. We're now in phase two.
Day to day, I focus on consumer growth and our digital + smart product roadmap.

Investing
I write small checks into startups as an individual and scout for Bain Capital Ventures. I try to stick to areas that I understand: commerce, proptech and consumer brands, along with supporting my unreasonably talented friends in anything they build.
Active investments include:
- Commerce: Highbeam (neobank for brands), Upscale (creative generation + DSP for connected TV), Heavi AI (managed marketplace for heavy trucking), Intelligems (AB testing and personalization), Fermat (personalized ecommerce at scale), Workmagic (incrementality testing), Clerq (pay by bank)
- Proptech: Boom Pay (modern rental financial services), Inspectify (property inspections)
- Brands: Tin Can (new school landline for kids), Rose (keeping your home healthy)
- General: Spark (a better way to help seniors find Medicare), Inherent (recursively self-improving to discover new knowledge), Every (applied AI lab for work and thought), Spara (conversational AI that closes), Fonzi (recruiting for the AI age), UnitZero.ai

- Since 2025, I've taught a course at Yale called Becoming A Founder, which is not-so-secretly a class on how to find and follow intrinsic motivation.
- In 2018, I was a Venture Fellow at Notation Capital, where I researched frontier tech and explored ideas in real estate, AR/VR, the gig economy and publishing.
- In 2017, I co-founded Recess Labs, a community in NYC for technologists exploring new ideas. In the year I ran the program, we partnered with Company, fka Grand Central Tech to serve 30 fellows across two batches. Alums of Recess have collectively raised well into nine figures of venture funding and built iconic products; other alums have become incredible coaches, writers, investors and open source maintainers. Most importantly, I met some of my best friends through this community.
- From summer 2016 through spring 2017, I traveled around Europe, Asia and North America. Highlights include joining a road trip from London to Mongolia as part of the largest team ever fielded for the Mongol Rally and writing a drawer novel.
- From 2013 to 2016, I was the first hire on the New Ventures team at Redfin. I worked on partnerships, corp dev and new business lines, including: our acquisition of Walk Score, writing the business plan for Redfin Now, and leading our exploration of VR.
- I studied Ethics, Politics and Economics at Yale. While there, I learned about investing over three years interning for David Swensen and the team at the Yale Endowment.
