Josh Elkes Took the Scenic Route to the Signature

Before Josh Elkes built software for agreements, his songs reached a producer by way of a garage sale. An acquaintance passed Neil Dorfsman a CD of Elkes’s early recordings in upstate New York. Dorfsman got in touch. Clifford Carter joined the project. A young songwriter acquired collaborators whose credits belonged in the liner notes of records he might reasonably have admired.

There is something pleasing about that route into the music business: a recording changes hands, someone listens, a working relationship begins. The unplanned introduction is doing all the work. Years later, Elkes would devote his attention to what happens after people decide they want to work together. A song can travel remarkably lightly. Permission to use it tends to bring luggage.

Today, the San Francisco founder leads Harbour and SuperDoc, working on contracts and the machinery of digital documents. His public biography still contains the music. It also contains long-distance running, cultural institutions and nonprofit work. These pursuits give his business career an unusually legible context. He has spent time making things, arranging partnerships around them and helping organizations get their work into other people’s hands.

A record, then the rights

The musical career left an actual artifact. His self-titled EP appeared in 2013, with Elkes credited on vocals and acoustic guitar and among its producers. Dorfsman recorded and mixed it; Carter played keyboards; Ted Jensen mastered it at Sterling Sound. That is a substantial company of collaborators for an early release. The credits record a team effort, down to the percussion and backing vocals.

Elkes performed around New York, including at the Living Room, Rockwood Music Hall, City Winery and Pianos. His music remains available to hear. It gives the later phrase “creator economy” a useful human scale: a person writing songs, rehearsing with musicians and appearing in rooms where somebody has to persuade an audience to listen.

His professional work also took him inside media businesses. At Getty Images he worked in strategic development; his career included Downtown Music and Viacom. Those are businesses in which creative material travels through commercial relationships. The image or recording may be immediately understandable. The rights around it require considerably more care. Elkes encountered that administrative world from inside the business of content.

The musician and the licensing executive had different jobs, but both were concerned with work reaching an audience. Listening to a recording is easy. Arranging for a business to use creative work introduces questions about ownership, permission and agreement. That distance between a promising idea and an executable partnership became the territory of his next business.

An introduction at the ballet

Harbour’s founding partnership began at a San Francisco Ballet event. Elkes and Eric Doversberger were there with their wives. Their conversation found its way to the cumbersome business of legal workflows. A ballet audience is an agreeable place to meet a future technology co-founder. It is also a reminder that professional networks sometimes form while everyone is supposed to be looking at something else.

Doversberger brought more than a decade of experience in Google’s people analytics team, including data visualization and reporting systems. Elkes brought the content background. The combination gave Harbour two perspectives on the same problem: the business relationship that needs an agreement, and the information that must move through a system once that relationship exists.

Harbour lets organizations handle agreements through shareable links and embedded workflows. The idea is easy to appreciate without becoming enthusiastic about contract administration. When a business needs many people to sign, approve or supply information, each unnecessary step becomes somebody’s recurring task. A reusable workflow makes the next agreement less of a fresh administrative expedition.

That focus later brought another music-business connection into the operating team. Chris Crawford joined as chief operating officer after being an early investor and adviser. He had co-founded Loudr, which Spotify acquired in 2018. In announcing his arrival, Crawford described Harbour as a way to help creative, business affairs and legal professionals clear rights and enable partnerships at scale. Elkes was building with people who recognized the work behind the paperwork.

“We founded Harbour to help the world create together.”

Josh Elkes, October 2023

In October 2023, Elkes announced Harbour’s $15 million Series A, led by Adyen co-founder Arnout Schuijff. His announcement described a team of 12 and plans to expand sales, product and engineering. The funding was a company milestone. The purpose he attached to it was more revealing: making collaborative contracting available to more customers. Even when discussing capital, he returned to people trying to make something together.

The long way across Haiti

Running supplies another strand of the biography. Elkes ran his first marathon in New York in 2011. By early 2015 he was taking part in Run Across Haiti, a fundraising journey of 230 miles from Cap-Haïtien to Jacmel. The distance alone makes an ordinary marathon sound almost conveniently scheduled.

The introduction came through Ethan Zohn, founder of Grassroot Soccer, who connected him with Team Tassy founder Ian Rosenberger. Elkes met Rosenberger in December; by February he was in Haiti. The undertaking supported an organization focused on helping people move out of poverty through sustainable employment. His explanation of joining centered on that practical emphasis on opportunity and independence.

“Seeing a whole new country and getting to see something new with every step I took was incredible,” he said afterward. The observation is about attention as much as distance. Moving through a place on foot changes the unit of experience: each turn and roadside encounter belongs to the journey. The undertaking also joined two activities already important to him, running and nonprofit partnerships.

Those commitments extended into formal roles. His public professional profile lists service with Team Tassy, the San Francisco Chamber Orchestra and OnePurpose School, as well as involvement with Lincoln Center and the Guggenheim. The list moves between employment, education and access to the arts. It gives his working life a wider field of relationships than the usual sequence of job titles.

The chamber orchestra role is especially apt for a recording musician. The organization provides admission-free concerts and educational programming across the Bay Area. OnePurpose, meanwhile, was a public charter school serving San Francisco’s Bayview neighborhood. These were specific institutional commitments, with audiences and students attached. Putting them beside the software work changes the picture a little: the founder’s network includes people concerned with who gets to participate, who gets access and what an organization must arrange before either can happen.

Permission to let a book travel

One quieter project brings the threads together particularly well. Elkes helped fund the creation of the Did You Know? collection of digital science books for young readers. The collection was designed for translation and for use by educational and nonprofit organizations. Its credits acknowledge his financial support alongside Adam Julian Goldstein and the organizations that helped bring the books into circulation.

The project pairs accessible reading material with the Goldstein License, which addresses how that material can be shared. Under its terms, creators retain copyright while qualifying educational and nonprofit uses can reach readers without charging them for access. The ambition includes distribution across languages. A book can be written beautifully and still need a practical route to the child who will read it.

This is a useful companion to Elkes’s commercial work. Both concern the terms on which creative material moves. The children’s books also show how specific that question can become. Someone must fund the writing, organize the production and establish permissions that distributing organizations understand. The modest machinery behind access deserves some attention of its own.

Now the document has to keep up

SuperDoc moves Elkes closer to the document itself. Harbour was publicly demonstrating the editor in January 2025. His current professional profile names him as co-founder and CEO of both businesses. SuperDoc provides an open-source document editor and tools for developers working with Word-compatible DOCX files, in browsers and on servers.

That work has acquired new relevance as AI systems begin editing documents. A suggested sentence is only one part of the job. The surrounding file contains formatting, comments, references and tracked changes. In his public posts, Elkes has repeatedly focused on preserving those details so that the resulting document remains something a person can review and continue working on.

In January 2026, he highlighted a SuperDoc extension that brings DOCX editing into VS Code, alongside AI agents. In February, he discussed Jamie Tso’s demonstration of edits across several documents, with tracked changes available for review. These are concrete examples of the direction he is pursuing: people and software working on the same files, with an understandable record of what changed.

By September, he was celebrating a narrower achievement with the pleasure of someone who runs against a clock. A team demonstration loaded the same footnote-heavy, 400-page document in about 12 seconds in an earlier version and under two in the newer one. Those were results from a controlled local test, rather than a promise for every file. Elkes connected the incremental work of shaving seconds to running.

The garage-sale CD and the editable Word file belong to different chapters of his career. Each involves work passing from one person to another and remaining useful when it arrives. Elkes has been the musician waiting to be heard, the executive arranging content partnerships and the founder attending to the mechanics of agreement. His current task is smaller than a grand theory of creativity, and more exacting: make the next handoff work.
