Your firm,
running itself.
Built by a solo attorney (Tulane Law ’16) who lived the billing gaps, the dropped follow-ups, and the deadlines buried in email.
Never forget a client follow-up again. Never lose billable time to admin. Never miss a deadline buried in an email.
Cardboard Legal is the Chief of Staff your firm can't afford to hire — and doesn't need to.
Most solo and small firms don't have an operations problem.
They have a bandwidth problem.
A good COO can double a small firm's profitability without touching a single brief. Most solo attorneys will never be able to afford one. We fixed that.
"Client emails pile up and follow-ups get dropped"
Every client communication tracked. Automatic follow-up drafts when clients go quiet. Nothing falls through.
"Billing hours lost because you forgot to log them"
Desktop observer watches what you work on, suggests time entries for your approval. Attorneys report recapturing hours previously lost to admin.
"Invoices sent weeks late, collections a mess"
Aged receivables dashboard, automatic payment reminders, collection risk scoring per client. Know which clients need a call.
"Deadlines buried in emails, missed court dates"
Scans your calendar and inbox for deadline language. Court dates, opposing counsel notices, informal deadlines — all surfaced for review.
"Intake is ad hoc. Promising leads call once and never hear back."
Every inquiry captured and followed up automatically. Get a reminder when a promising lead goes cold. One click to convert to a matter when they sign. No more “I meant to call them back.”
"No visibility into how the practice is actually performing"
COO dashboard: matters at risk, collection forecast, unbilled time, dormant leads worth reactivating. The view you never had time to build.
Not AI for legal research.
AI for running a law practice.
Harvey, Legora, and Claude are intelligence tools. They make you better at legal reasoning. Cardboard Legal makes your practice better at running — intake discipline, billing capture, collections follow-through, client communication continuity.
The attorneys we've talked to don't need better legal theory. They need to stop losing 30% of their revenue to admin chaos and billing gaps.

Common questions
Your firm shouldn't need a COO.
It should just run.
Pilot is open now. Small cohort — we're taking fewer than 20 firms before we open broadly. You'll work directly with the founders and your feedback shapes the product.
