COVID-19 has accelerated the digitization of commerce globally. In the US, e-commerce penetration increased from 16% at the end of 2019 to 27% in April 2020. While most of the news covering the pandemic’s impact on commerce has highlighted the growth in business to consumer (B2C) e-commerce, little has been said about how business to business (B2B) commerce has changed.

Across the globe, as the novel coronavirus moves us from communal spaces into the confinement of our homes, our social experiences are forced to adapt. Beyond the social networks we already know and use, we are finding new ways to integrate social into our online lives. At Y Combinator, we are considering what this might mean for the future of e-commerce.

This batch marks the completion of my first year as President of YC — and what an amazing year it’s been. During the last batch we moved Y Combinator into a beautiful office in San Francisco’s Dogpatch neighborhood. This batch we took over a massive building next door, too — more than tripling the space available to us.

Earlier today Michael shared an update with the YC community, outlining a shift to his role within YC moving forward. After 8 years as the Managing Director/CEO of the YC accelerator, I’ve decided now is the right time to hand over my leadership responsibilities.

Tim Brady and I go back a long way. Tim was already at Yahoo! when my company was acquired in 1997. Of course, Tim was there. In fact, he was Yahoo!’s first employee and ran a group called “production” until he eventually became Chief Product Officer. Tim was, in many ways, the conscience of Yahoo! He kept us focused on the customer experience in an era when it was too easy to toss that aside in a search for revenue.

Scaling a startup is hard. Scaling a startup bank is even harder. Scaling a consumer-focused financial platform—that is also now the primary bank account for millions of UK consumers—in the midst of a once in a century pandemic is close to impossible. In April 2020, British banking startup Monzo’s revenue fell by almost 50%. But the company will end 2021 with revenues close to 2x its pre-pandemic peak, in spite of continued low interest rates, reduced travel, and depressed pandemic spending.

A frequent question we get at YC is “when do I start thinking about the FDA?” Obviously, there is no single answer to such a complex question, but here are some basic rules of thumb for how to think about it: It makes sense for every founder considering a bio product to get a basic FDA education from day one. Choosing the proper regulatory pathway is nuanced; research and experts can help.

YC was founded around the idea that technologists should be at the center of tech innovation. It seems obvious today, but it wasn’t always that way. We believe that technology startups should include a technical founder because it is critical that a CTO have a seat at the table where key decisions regarding the future of the startup are made. When it comes to deciding what to do with technology, technical founders know what the options are and what kinds of problems are hard and which are easy.

In the early stages of working on a startup, there is little time to spend on areas other than product development and talking to users. However, as you start to hire people and build a team, there are HR fundamentals worth investing in. Having basic HR practices in place can help your startup scale quickly and may eliminate unforeseen and often costly problems down the road.

If you build something because you need it, chances are good others need it too. RevenueCat (YC S18) is an excellent example of this. While adding in-app subscriptions to an iOS application, RevenueCat’s co-founders realized they were spending a ton of time building out the behind-the-scenes plumbing. It was necessary work, but it meant way less time for the features they actually wanted to create.

A huge part of that equation, as anyone who has woken up at 2 a.m. to throw the blanket off could tell you, is temperature.
