About

At XMTP Labs, we're reimagining the future of decentralized, secure, and portable messaging. We believe that privacy is an inalienable and universal right.

We're committed to creating a powerful communication protocol that is truly open to all. In our vision, users not only own and control their own identity and data, but also benefit economically from their participation, all while breaking free from single-entity control. Our mission at XMTP Labs is to build a secure, open, and decentralized communication protocol that connects creators, communities, applications, and users. If this mission speaks to you, let's build the future of messaging together.

We’re backed by some of the best investors in tech and crypto: a16z Crypto, Offline Ventures, Sound Ventures, Distributed Global, Redpoint, IDEO CoLab and many more key ecosystem investors and operators. See the full list here.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
