Industry considerations
Legaltech SaaS considerations
What a founder weighs before building SaaS for lawyers and legal teams: who buys, the professional rules, data questions and the sales cycle.
This page sets out what building SaaS for lawyers and legal teams asks of a founder, in general terms.
The perimeter below reads one New York statute and United States federal rules, and the rules of other states are outside this page.
What WE's teams can and cannot build
- WE is a long-horizon business incubation and consulting firm that steers a dedicated, fully remote team building the company with its founder.
- The team builds software: architecture, an agile build in short cycles and a pilot environment where early customers can use the product.
- The team does not run a live service, because WE builds to pilot scale.
- The team does not store or process restricted or regulated data in WE systems.
- WE gives no assurance that a product will pass a particular audit or hold a particular certification.
- WE does not give legal, tax, accounting, insurance or compliance advice.
- WE coordinates a founder’s own counsel and other specialists, and the founder engages them directly.
Who buys and who decides
The buyer is often a law firm or an in-house legal department, and the lawyers who carry professional obligations are rarely the only people who decide. Name who bears the professional obligation, who owns the budget and who reviews technology before the first demo.
The regulatory and standards perimeter
-
Practicing law without a license
New YorkAs of October 10, 2026
New York’s Judiciary Law, section 478, makes it unlawful for a natural person to practice or appear as an attorney-at-law for another person in a court of record without first being licensed and admitted to practice law. Whether a product’s output counts as legal services is a question for counsel in each state where the product is offered.
-
Confidentiality of information
US federal, USPTO practiceAs of October 10, 2026
The rules of professional conduct at 37 CFR 11.106 require a practitioner to make reasonable efforts to prevent the inadvertent or unauthorized disclosure of information relating to a representation. Other jurisdictions have comparable rules, which this page does not cover.

Supervising non-lawyer assistance
US federal, USPTO practiceAs of October 10, 2026
The same rules, at 37 CFR 11.503, require a practitioner with supervisory authority to make reasonable efforts to ensure that a non-practitioner assistant’s conduct is compatible with the practitioner’s obligations. A buyer may ask a software vendor how its handling of information supports that duty.
-
Waiver of privilege by disclosure
US federalAs of October 10, 2026
Federal Rule of Evidence 502 limits waiver of the attorney-client privilege and work-product protection, and says a disclosure made in a federal proceeding or to a federal office or agency does not operate as a waiver if it was inadvertent, reasonable steps were taken to prevent it and the holder acted promptly to correct it.
Questions about data handling
- Does the product receive information relating to a representation, and where is it stored and who can reach it?
- What can the buyer tell its own reviewers about how the vendor handles that information?
- Could any output look like legal advice to a person who is not a lawyer, and in which jurisdictions is the product offered?
- If a document is shared by mistake, what steps does the product give the buyer to limit the effect?
The sales cycle
A lawyer who buys software carries professional obligations about confidentiality and about supervising non-lawyer assistance, so a buyer’s review is likely to focus on how information is handled. Plan for that review as a stage of the sale.
