Will Robbins

Hi, I’m Will!

I’m investing and building at Contrary, a venture fund backed by founders from Tesla, Reddit, Twitch, and more. I’m also an ambassador for Sequoia Capital.

You can learn more about me through TwitterLinkedInGitHub, and email.

I sometimes write about things that interest me.

Broadly speaking, that includes startups, investing, software, psychology, evolutionary biology, ethics, AI/ML, and these important questions.

In my free time I discover new music (check out one of my 50+ public playlists), travel (I’ve set foot in all but 2 states), and read.

Check out Contrary Radio, my series of conversations with founders from companies like Airbnb and OkCupid.

I love unsolicited feedback. Please anonymously send me some!

Projects

V.F.S. Volume 1 – my first ever mixtape. Inspired by ODESZA’s NO.SLEEP mixes.

Twitter-Tools – a Twitter API wrapper that makes basic analytics and data munging easier

Brick Breaker Free – in high school I taught myself Android and wrote Brick Breaker Free, a clone of the classic game Breakout. It was downloaded over 100k times. (Has since been taken offline for having an ancient Google-non-compliant ad library…)

Techwurk.org – I cofounded Techwurk in high school to connect charities with students interested in web design. Through my school’s “startup incubator” program, I successfully pitched the idea to a panel of investors, and won a grant to help expand the business.

Perspective – a Chrome extension that parses a web page looking for textual representations of dollar amounts. It then manipulates the DOM to replace each dollar value with a phrase representing potential charitable impact. For example, a page saying “buy now for $4.99!” would be changed to something like “buy now for enough money to donate an anti-malarial mosquito net!” This small project was inspired by FlipWord.

Neural Network Text Generator – a recurrent neural network architecture to generate coherent English based on a seed phrase (independent final project for PSYC 489 so ask me for source).

Interest Matcher – a location-based web app that facilitates the discovery of events on campus. Chill shared a lot of functionality with Yik Yak, but it is not anonymous. I built it with and handful of other students in Fall 2015. Now it’s offline and unmaintained — ask me for source if interested.
