David Durand

He spent two decades writing the standards that quietly run the web. Then he built Tizra so publishers would never have to think about them.

The work right now

A platform for content that refuses to sit in a drawer.

Dave Durand runs Tizra out of Providence, Rhode Island, where the company builds the digital plumbing that lets associations and scholarly publishers sell, organize, and actually deliver their content. The customer list reads like a roll call of institutions you'd trust with your health and your homework: the American Dental Association, the American Hospital Association, and dozens of other groups sitting on libraries of high-value material.

The pitch is simple and a little subversive. Most publishers spend a fortune producing content and then bury it where nobody can find it. Tizra's job is to make that content searchable, sellable, and connected - an eStore, a digital library, and an open hub that snaps into the AMS, CRM, and LMS tools a modern association already runs. Durand calls himself the visionary behind the platform. The people who use it would just say their content finally works.

What makes him unusual for a software CEO is the resume underneath the title. Before he was selling subscriptions for publishers, he was helping invent the formats those publishers would one day publish in. He has been working with markup languages and hypertext since 1984 - a date worth sitting with, because the World Wide Web did not yet exist.

// how David Durand describes the job
The long way here

He met hypertext before most people met a computer.

The detail that explains Durand is this one: as a faculty member's kid, he got to use FRESS - one of the earliest hypertext systems, built at Brown - while he was still in high school. Most teenagers in that era were lucky to see a terminal. He was clicking through linked documents on a vector display.

That early exposure stuck. In 1989, he and Steven DeRose did something gloriously nerdy and historically generous: they built an emulator to recreate FRESS's original graphics so they could demo a 1960s machine, live, at the ACM Hypertext Conference. It is the kind of move that tells you everything - the man who would later sell content platforms cared enough about the roots of the field to rebuild a museum piece from scratch.

From there the path runs through the standards bodies that built the readable web. He took part in the Text Encoding Initiative, in XML, in HyTime, in XLink, and in WebDAV. In 1994 he and DeRose published Making Hypermedia Work: A User's Guide to HyTime - the first in-depth guide to a standard that tried to describe how time, links, and media should fit together. The web that arrived a few years later borrowed liberally from that thinking.

Along the way he served as Chief Scientist at Brown's Scholarly Technology Group and taught as an Adjunct Associate Professor in the university's Computer Science department. He earned a PhD in document engineering and collaborative editing - the academic version of the exact problem Tizra would later solve commercially: how do many people work on, structure, and find their way through complex documents?

Then came industry. He led software architecture at Ingenta and served as CTO at Dynamic Diagrams, sharpening the question that had followed him since FRESS. In 2006 he and Abe Dane - a consumer-publishing veteran with bylines across national magazines and stints at Popular Mechanics, Hearst, and MIT - turned that question into a company.

Things worth knowing

The footnotes that aren't boring.

01 / FRESS

A teenager on a hypertext machine

Faculty-kid access let him use one of the first hypertext systems in high school - decades before browsers made links ordinary.

02 / THE QUIRE

He sings shellfish

Off the clock, Durand sings with Providence's Quahog Quire, named after Rhode Island's beloved hard-shell clam.

03 / SOLDER

Vintage electronics, by hand

When he's not in code, he restores and tinkers with old electronics - the analog cousin of debugging.

04 / HYTIME

A book before the web grew up

His 1994 HyTime guide predates the mainstream web - a manual for ideas the web would later adopt.

05 / THE PHD

He studied the exact problem he'd later sell

His doctorate on document engineering and collaborative editing became Tizra's commercial mission.

06 / THE CLIENTS

Trusted by the big institutions

The American Dental Association and American Hospital Association run their content on what he built.

Content should be found, not buried.
