Why LexiSync

Built by engineers who worked
inside four law firms.

Not researched from the outside. Not designed from a survey. Four firms commissioned bespoke tools for how they actually practice — and those tools are still running in those firms today. They became this platform.

It began as bespoke work, not as a product.

A personal injury firm was sending medical records out to a third-party service, paying by the page and waiting three days for a chronology. They asked whether it could be done differently. It could — seven reports came back in sixty-three seconds for eight cents. The outsourcing ended that week.

A family law practice was spending half a day per client turning an intake form into court documents, re-typing the same details three times along the way. They asked for the same thing. Now the intake form produces the documents.

That happened four times, at four firms, over a year — each one designed, built, and put into production inside the practice it was for. At some point it stopped being four separate projects and started being one platform. The firms had already decided the pieces were worth having; they were using them every day.

The features weren’t chosen from a roadmap. They were the things four working firms asked for by name, and kept using after they got them.

Built with Kristen Tarrin.

Name partner, McLaughlin Tarrin Law, LLC · Family law since 2006

Colorado courts appoint Kristen as a Child and Family Investigator, Child Legal Representative, Guardian ad Litem, and Counsel for Youth — the roles where a judge, not a client, picks the attorney and then relies on what she reports back. Her work is read by judges and taken apart line by line by opposing counsel.

Hers was the first firm on LexiSync, and the family law side was scoped with her. She has spent a year running live matters on it, which is why it follows the way the work is actually done — not the way a software company imagines it.

Kristen holds equity in LexiSync, and her firm runs on it. Both seemed worth saying.

Three things you can only get this way.

01
The unglamorous problems got solved
Software designed from a distance solves the problems that are easy to describe. Working inside a firm, you find the ones nobody thinks to mention — the third re-typing of the same address, the format the court will reject, the file that only one paralegal knows how to assemble.
02
Two practice areas, not ten
The firms were personal injury and family law, so that is what this is built for. Covering every practice area would have meant understanding none of them, and small firms can tell the difference within about five minutes of a demo.
03
There is no handoff
The people who designed it wrote the code, integrated it, and run it in the cloud. No offshore team, no account manager relaying your question to someone who might answer it. When you ask why something works a particular way, you get the answer from whoever decided it.

Two engineers. No one in between.

Co-founder
David Segala, Ph.D.

Sixteen years building machine learning that had to survive review before anyone would act on it. Eight years with the Navy, in and out of uniform: as a civilian leading machine learning and analytics for a Naval command, including evaluating technology deployed on US ships, and at the same time as a Navy Reserve intelligence officer. A PhD in applied mechanics that produced a new machine learning algorithm derived from first principles, twenty-plus peer-reviewed papers, and a patent.

Then four small law firms, working inside each one on the tools that became LexiSync. The review standard came with him: every finding in LexiSync cites the page it came from.

Co-founder, Engineering
Chris Casciano

Building software since 1991, and for most of the last two decades protecting confidential data inside customer systems: data loss prevention, public key infrastructure, PCI compliance, and encryption that took raw cardholder data out of retail point-of-sale. He ran a certificate-authority engineering program.

In 2000 he worked on bedside clinical documentation for neonatal and pediatric intensive care — protected health information captured and synced securely, with nothing re-entered by hand. At LexiSync he leads engineering: the document generation engine, the cloud architecture, and every decision about how a privileged file is stored, encrypted, and logged.

What this isn’t.

A small firm evaluating software deserves to know the edges before it signs, not after.

Forty-five minutes, on your practice.

Bring a document, a set of records, or just the part of your week you most resent. If LexiSync isn’t the right fit, we’ll tell you on the call rather than after you’ve signed.
