The themes of my work include data, machine learning, natural language, disinformation, politics, elections, organizing, and spatial audio.

I consider myself a professional inventor, entrepreneur, software engineer, and data scientist.

I’ve co-founded two nonprofits and one startup, which was acquired.

I have written for The New York Times and The Information.

Facebook Lexicon

In 2008 I built “Google Trends for Facebook” with a colleague.

We were able to predict Obama and McCain favorability ratings 3 days before the Rasmussen tracking polls came out.

We also were able to predict CDC’s hospital flu data better than Google Trends.

In 2008, two friends and I built an SMS-based happiness self-tracking system that would randomly sample a user's mood throughout the day, and provide them with personal well-being analytics.

Facebook Research Polls

From 2008 to 2011 I built Facebook’s research polling platform.

To my knowledge, it is the most powerful polling platform currently in existence.

Facebook Mood and Activity Sharing

From 2012-2013, I built and launched Mood and Activity Sharing on Facebook with a small team.

Mood and Activity Sharing — the smiley button in the status composer — lets Facebook users add a feeling or an activity to their posts with an emoji.

This simple feature made it easier and more acceptable for Facebook users to share a wider range of human emotions.

In 2014, I built and launched one of the first Augmented Reality (AR) applications for iOS.

WineGlass allows users to take a photo of a wine list and browse ratings, reviews, and reasonable prices for each wine.

WineGlass peaked at the #4 Paid App in the App Store.

In 2014, I co-founded and currently serve as board chair for Envelop, a nonprofit whose mission is to unite humanity through profound communal listening experiences.

We achieve our mission through community-supported immersive audio venues, inspiring events, educational programs, and free open-source spatial audio software tools.

We have put on more than 700 immersive listening events at our physical and online venues.

Envelop for Live

In 2009, I started developing open-source software for musicians to control multichannel audio arrays using Ableton Live.

A friend and I wrote the initial version in Pd. The latest version, for Live 10, is written in Max/MSP with Max for Live. I contributed several effects to the most recent version.

In 2014, I co-founded my startup Hustle with Perry Rosenstein and Tyler Brock. Hustle empowers organizations to humanize communication through text messaging.

Hustle has delivered more than 500 million text messages on behalf of progressive and Democratic organizers.

We went from zero to $10m in annual revenue in 4 years.

I served as CEO from 2014 to 2019, and currently serve as Chief Evangelist.

Acquired by Social Capital in 2020.

P2P Texting

Hustle is the result of my 2014 invention of P2P texting, the political and community organizing method now widely used by campaigns and nonprofits.

My invention of P2P texting was heavily influenced by the work of Saul Alinsky, Hahrie Han, and Marshall Ganz.

In one study, P2P texting increased the 2020 Democratic turnout among least likely voters by 19.4 percentage points.

P2P Alliance

In 2018, I co-founded a bipartisan industry trade group for the P2P texting industry.

We petitioned the FCC in 2018 with the support of the NAACP, the National Black Justice Coalition, and the Bay Area Council.

In 2020 the FCC ruled in our favor, and we were granted a key ruling that clarified the regulatory status of P2P texting technology.


In 2020, I built and released the first-ever live stream transcoder to support Higher-Order Ambisonics, an open-source tool called Earshot.

Earshot enables next-generation immersive audio experiences for the web and VR/AR/XR platforms.

Campaign Verify

In 2020, I created and served as a founding board member for Campaign Verify, a non-partisan, nonprofit service for U.S. political campaigns, parties, and PACs to verify their identity.

Campaign Verify helps protect the integrity of elections by serving as a trusted identity broker for U.S. wireless messaging networks and digital communication services.

DJ / Live PA

I have been DJing since 2002. I play House, Disco, Downtempo and Ambient music.

I collect vinyl records — mostly disco and post-disco from the late 70’s and early 80’s. I also enjoy making edits.

I perform a surround-sound Live PA with Ableton and Envelop for Live. I’ve played at FORM Arcosanti several times.


I have been awarded 25 patents, and have several others pending.
