Overview
What Crosby is
Crosby focuses on reducing the legal delay between a sales agreement arriving and reaching signature. Its public materials emphasize recurring commercial documents such as master service agreements, data processing agreements, non-disclosure agreements, SaaS and vendor contracts, and technology or data-rights terms.
The workflow combines automation with professional judgment. Custom legal agents process agreements against the client's preferences and contract history, while lawyers review difficult issues, exceptions, and negotiation strategy. Crosby says it is a registered law firm with malpractice insurance and stands behind the delivered work.
This distinction matters when comparing Crosby with legal AI software. A company is engaging a law firm and its technology-enabled service rather than merely licensing an assistant for its own lawyers. Scope, jurisdiction, attorney-client relationship, conflicts, confidentiality, service levels, and responsibility should therefore be confirmed in the engagement documents.
Use cases
Who Crosby is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Lean in-house legal teams
Add capacity for repeat commercial agreements while keeping internal counsel focused on novel, high-risk, and strategic issues.
Companies with repeatable playbooks
Apply established fallback positions, approval rules, risk thresholds, and prior negotiation patterns across new deals.
Slack-centered deal desks
Submit agreements and receive legal coordination where sales teams already work, while maintaining visibility for in-house counsel.
Capabilities
Core Crosby features
AI-assisted contract review
Legal agents identify clauses, compare terms with the client's position, draft redlines, and prepare issues for lawyer review.
Lawyers in the loop
Barred attorneys apply judgment to difficult language, commercial tradeoffs, escalations, and counterparty negotiations.
Client-specific playbooks
Encodes preferred language, fallback positions, approval paths, and risk tolerances instead of applying one generic contract standard.
Contract knowledge layer
Crosby's case studies describe a client-specific system called Crosbrain that stores prior agreements, decisions, counterparty positions, and internal context.
Embedded intake
Accepts a document or legal question through Slack, email, or a trigger from a contract-lifecycle-management system.
Negotiation support
Provides revised documents, issue guidance, escalation, and legal-to-legal coordination rather than stopping at a risk summary.
Fixed document pricing
Bills by document at an agreed rate rather than using an open-ended hourly model.
Law-firm accountability
Crosby says it is a registered law firm, carries malpractice insurance, takes liability for its work, and is not merely selling software.
Process
How the Crosby workflow works
Step 1
Confirm the engagement
Define covered entities, jurisdictions, document types, conflicts process, service levels, privileged communications, data handling, and who can instruct the firm.
Step 2
Build the legal playbook
Document preferred clauses, fallback language, commercial tradeoffs, approval thresholds, and issues that always require in-house escalation.
Step 3
Connect the intake channel
Route contracts through Slack, email, or the team's contract-management trigger with the deal context Crosby needs.
Step 4
Let agents prepare the review
Crosby's system analyzes the document, compares it with client rules and precedent, and drafts redlines or issue summaries.
Step 5
Apply attorney judgment
Crosby lawyers review difficult points, resolve exceptions, and coordinate with internal counsel or the counterparty where necessary.
Step 6
Capture the decision
Save the negotiated language, approvals, and reasoning so the client's playbook and institutional contract history improve over time.
Cost
Crosby pricing and free plan
Crosby advertises upfront, fixed rates by document rather than hourly billing, but does not publish dollar amounts. Pricing therefore requires a direct proposal and should be evaluated against document complexity, turnaround commitments, negotiation coverage, volume, and the attorney services included.

Assessment
Crosby strengths and limitations
Where it stands out
- Combines automation with actual attorney review and responsibility
- Designed around the commercial-contract bottleneck that directly affects sales cycles
- Works inside Slack, email, and connected contract workflows
- Learns company-specific positions and precedent instead of applying only a generic checklist
- Fixed document rates provide more predictability than open-ended hourly billing
- Can add repeat-contract capacity without requiring a company to build its own legal AI stack
- Crosby publicly states that it is a registered firm with malpractice insurance
What to consider
- No public dollar pricing is available, so cost comparison requires a sales and legal engagement process
- Public materials concentrate on commercial contracting; litigation, tax, employment, regulatory, patent, and other practices should not be assumed
- Turnaround and outcome figures on Crosby's site are company-published case studies and may not generalize to every contract
- The usefulness of automation depends on a well-defined playbook, clean contract history, and prompt access to business approvers
- Complex or novel matters still require attorney judgment and may not fit a rapid standardized workflow
- Companies should verify bar coverage, conflicts, privilege, malpractice terms, data processing, subprocessors, retention, and cross-border handling in the engagement
- Crosby's public privacy notice is dated September 2024 and describes an earlier service that did not provide legal advice, so current engagement documents should govern the present law-firm relationship
- A managed law-firm service offers less self-service control than legal AI software operated entirely by an internal team

Crosby FAQs
Is Crosby a law firm or an AI software tool?
Crosby describes itself as a vertically integrated AI-native law firm, not merely software. It says barred lawyers review the work, the firm carries malpractice insurance, and it takes liability for its legal service.
What contracts does Crosby handle?
Its public materials focus on commercial agreements for growing companies, including MSAs, DPAs, NDAs, SaaS, vendor, licensing, and data-rights terms. Confirm the exact practice scope in the engagement letter.
How much does Crosby cost?
Crosby advertises fixed rates by document rather than hourly billing but does not publish the dollar amount. Companies need a quote based on their document mix, volume, complexity, and required service level.
Does a lawyer review Crosby's work?
Yes. Crosby says legal agents process agreements while barred attorneys weigh in on difficult issues and ensure accuracy. Clients should still confirm the assigned lawyers, supervision, jurisdiction, and escalation rules.
How do teams send contracts to Crosby?
Crosby accepts documents and legal questions through Slack, email, or a trigger from a contract-lifecycle-management workflow.
How fast is Crosby?
Crosby publishes examples ranging from under an hour to several hours for commercial reviews, but those are company-reported medians and case studies rather than a universal guarantee. The applicable service level should be written into the engagement.
Can Crosby replace in-house counsel?
It can absorb repeat commercial-contract volume and coordination, but internal legal and business owners still need to set policy, approve risk, handle company-specific judgment, and oversee matters outside Crosby's agreed scope.
Bottom line
Our Crosby verdict
Crosby is compelling for a fast-growing company whose revenue contracts repeatedly bottleneck in a small legal team. Its law-firm model adds accountability that a self-serve AI reviewer cannot provide, while its agents and client memory can make repeat work faster. The tradeoff is limited public pricing and the need for a careful engagement review before confidential contracts and legal decisions move into the service.
