This is Where the Bold Come to Build
The Leaders
We Are Hands On
SOSV SF’s General Partners Po Bronson, Pae Wu and Mohan Iyer lead an expert team with a proven track record: SOSV SF’s companies have raised over $3 billion, have built factories over 400,000 square feet in size, and generated revenues in the tens of millions. We know how to do this. To build a portfolio this size, it’s meant supporting 100+ Series A’s, B’s, and C’s. That network is brought to bear on every new startup we fund.
Why Choose SF?
57% of Global Capital Deploys Here
Silicon Valley dominates venture capital. Startups in this small region of just 8 million people pull in 57% of all dollars deployed. The entire rest of the world splits 43%. We recommend to founders that, no matter where they come from, and no matter where they might build their future factories and supply chains, they anchor here.
Our 25,000 square foot facility has 5 lab areas – the main BSL1 lab, two BSL2 suites, an Analytical Chemistry lab, a Food Production lab, and a general-purpose Production Suite for scaled systems. Our offices offer lovely views of the San Francisco Bay ship traffic. We are located in the giant American Industrial Center a few blocks south of UCSF and the Chase Center. We are on a CalTrain stop and the T muni line.
We don’t require you to be here full time. Our founders have come from 40 countries. After we first invest, we do want you to be here in person for at least two week-long bootcamps, a few months apart. We want you to get to know investors here. You will always have an office here you can use.
Your First Investor Matters
Your VC Is a Critical Part of Your Team
The most common mistake founders make is that they optimize for valuation, rather than value creation. Two stacks of $500,000 are equivalent, but the two investors behind each stack are never of equal value. We specialize in being the hardest-working investor on your cap table. During those first six months of building your startup, no investor creates more real value than us.
We don’t spray and pray. Unlike most investors, we invest our most precious asset – our human capital – alongside our financial capital. Speed is a startups’ best weapon and our goal is simple: accelerate your company. We help you move faster by opening doors to customers and investors, supporting fundraising, and advising on the hundreds of small, but critical decisions that determine whether a startup takes off. Every company is supported by a dedicated team of 3–4 investors, including General Partners and Partners with experience in your sector. We meet with you weekly for focused, hands-on collaboration in person or over Zoom. Let us in, and let us help.

Our Origin
First-of-a-Kind DNA
SOSV SF is the birthplace of the legendary accelerator, IndieBio. Launched in 2015, IndieBio was the first venture-backed biotech accelerator in Silicon Valley with labs on site for scientists. IndieBio took the world by storm, entrusting a generation of post-docs to become startup founders. Today, SOSV SF retains this “first of a kind” DNA. As an investing team, we are dedicated to funding highly technical founders with the creativity and fortitude to break from conventional wisdom and take original approaches to solving the world’s problems.
Over time, we’ve learned a few things that guide us. One is that we do not index on only a certain archetype of founder. We have seen very heterogeneous founders create enormous value. We will take risks – we will run the experiment. We built a fund model that doesn’t avoid inherent risk, it reduces the dollar cost of that risk. This allows us to back startups that others won’t.
