We're making consent & independence the new normal.

We believe that consensual service providers and clients should be able to operate safely, privately and independently—and still benefit from reliable community standards, legal protections and non-exploitative digital solutions.

We know that the vast majority of individuals are law-abiding, yet everyone suffers from outdated stigmatizing stereotypes and a punitive culture that falsely claims that all participants are criminals or victims.

We also know that the marginalization of sex work and lack of protections for sex workers creates opportunity for abusive and exploitative bad actors. Non-consensual individuals are trafficked, and consensual workers find themselves in coercive or abusive working conditions because they’re unsupported in independent work or unable or afraid to work independently.

With horizontl, we’re upending the current system. The consenting majority gain technology and policy, under a socially responsible business model, that support safety, trust and inclusion—and combat the dangers of working in vulnerable isolation. Bad actors are pushed to the margins and more easily targeted by law enforcement, and interventions and resources can focus on helping victims.

The horizontl team.

Our team is committed to reimagining how business and technology can work better to serve people and communities.

Together we have years of hands-on business, technical, product and community experience and knowledge that we’re applying horizontl's new approaches to mission-driven business, community-led policy, cryptographic data protection, and decentralized system architecture.




Kate spent more than a decade helping launch and scale adtech and other big-data startups.

There she saw firsthand the ascent of business and technology designed to monetize and extract value from everything and everyone—and indifferent, and often actively hostile, to norms of democracy, community, and individual rights. Through anti-human trafficking work she came to see that sex workers are at the fore of suffering the consequences of this system and its unaccountable, authoritarian approach to data surveillance, use, and governance.

Following the passage FOSTA/SESTA in the US, she developed the idea for horizontl out of research into how technology, business and governance could converge in a purpose-built solution to protect consensual sex workers and take on exploitation and trafficking—and introduce a non-extractive, community-first tech model.

Protected identity is at the heart of horizontl.

Identity is a bind for sex workers and clients.

Everyone wants real identity data privacy. But everyone also wants the trust that can only come with knowing someone else’s real identity-based history of professional, non-abusive behavior.

Service providers and clients with resources and experience often develop their own ways to build trust in some degree of privacy, but it's inefficient and based on limited relevant information. And those without the resources or experience for careful vetting can find it nearly impossible to establish any degree of trust before making a booking.

At horizontl, we’re building the balance between private identity and accountable behavior.

Safe, trusted connection shouldn’t be a luxury.

For-purpose, for-profit:
The business of horizontl

Sex workers have always been used by other people to make lots of money. Middlemen charge exorbitant fees for the most basic (and often unreliable) services, and the wealth of a community of individuals is siphoned off and away rather than reinvested in products and services that improve working conditions for everyone.

With horizontl, we're creating a self-sustaining business (that isn't dependent on charity or handouts) with a mission and mandate to reinvest in solutions and services that benefit sex workers.

We plan to make money by charging a modest fee for identity and booking contracts services. With the introduction of privacy-protecting payments, we'll charge a small commission to handle those financial services. [A note on payments: Because of the complexity and limitations of existing regulation in conjunction with our proposed new approach to privacy-protecting payments, payment processing will be introduced in the future but won’t be part of the earliest horizontl product.]

With a business structure that locks in purpose, horizontl must develop new solutions and improve existing ones to serve our mission of "increasing workplace safety, improving financial security, and normalizing rights and protections for independent, consensual sex workers in order to reduce opportunities for exploitation and trafficking".

Once profitable, horizontl plans to create a fund for allocation by the sex worker community to external organizations and projects they support.
