The Problem

Marketing Changes Quarterly. Most Expert Databases Don’t.

Algorithms update monthly. Platform policies shift overnight. Campaign strategies that worked two years ago are obsolete today. Yet most expert witness services source retired professionals whose marketing knowledge stopped accumulating the day they left the field.

Stale Marketing Knowledge
An expert testifying about SEO who doesn’t understand current algorithm changes, or an advertising expert citing pre-iOS 14 attribution models, creates risk for your case — not credibility.
Credentials Without Clarity
Marketing is jargon-heavy. A qualified expert who can’t translate CTR, ROAS, or programmatic buying into plain language for a jury fails where it matters most — the stand.
Generalist Matching
Broad referral services treat “marketing” as one category. But the expert you need for a consumer survey in a Lanham Act case is a completely different person than the expert for an M&A dispute over marketing ROI projections.
Unvetted Daubert Risk
An expert excluded under a Daubert challenge doesn’t just weaken your case — it can end it. Methodology and reliability must be verified before the shortlist is built, not after.
Marketing Subspecialties

Litigation Types

Where Marketing Expertise Becomes Case-Decisive

Marketing expert testimony is relevant across a surprising range of commercial litigation. Each case type demands different subspecialty knowledge — and a different expert.

Trademark confusion, trade dress infringement, digital brand dilution, SEO/SEM keyword disputes, and reasonable royalty calculations for marketing IP.
Business Valuation & Damages
Marketing asset valuation, customer acquisition cost analysis, lost profits from marketing disruption, and brand equity damages quantification.
Employment & Non-Compete
Trade secrets in marketing strategies, customer list valuation, non-compete scope in marketing roles, and departing employee IP claims.
Regulatory & Compliance
FTC, FDA promotional standards, TCPA, CAN-SPAM, GDPR/CCPA in marketing contexts, and industry-specific advertising regulations.
How It Works

From First Call to Courtroom-Ready
in Five Steps

A structured engagement designed to deliver qualified, case-specific marketing expert candidates on litigation timelines.

01
Confidential Case Briefing
A 30-minute consultation to understand the marketing issues at the center of your case, your timeline, and whether you need a testifying expert, consulting expert, or both.
Protected under NDA. Conflict check completed before any substantive discussion begins. This consultation is complimentary.
02
Subspecialty-Matched Shortlist
Within 48 hours, we deliver 2–3 hand-selected marketing experts with full CVs, testimony history, and a written rationale explaining why each candidate’s specific marketing subspecialty maps to the claims in your case.
Every candidate is pre-screened for Daubert admissibility, conflict-cleared against all named parties, and assessed for communication under cross-examination.
03
Interview & Selection
Your team interviews the shortlisted experts directly. We facilitate introductions, but the final selection is always yours. You choose the marketing expert who best fits your case theory and communication style.
04
Engagement & Terms
We help finalize scope, deliverables, and billing structure. The retention agreement is executed directly between your firm and the expert. There is no markup on the expert’s hourly rate — ever.
Your search fee covers the match. The expert bills you directly at their standard rate. This eliminates cross-examination vulnerability around referral service markups.
05
Optional: Case Coordination
For firms that want end-to-end support, we manage the engagement lifecycle — scheduling, report deadlines, deposition prep logistics, and replacement sourcing if case dynamics change. A dedicated case manager keeps your marketing expert on track so your team focuses on strategy.
Why CLLC

What We Maintain So You Don’t Have To

Every litigation matter creates a new search problem — different subspecialty, different conflicts, different timeline. We solve it faster because we maintain the intelligence layer that no single contact can provide.

Conflict Intelligence
We track which marketing experts are conflicted against which parties across active matters. When you need someone with no ties to Meta, Google, or a specific competitor — we answer in hours, not days.
Availability Tracking
We know which experts are currently retained, which are approaching trial, and which have bandwidth. Your first-choice expert may be unavailable — we know that before you waste a week finding out.
Subspecialty Depth
The SEO expert you need for a non-compete case is a different person than the consumer survey expert you need for Lanham Act. We match at the subspecialty level across nine distinct marketing disciplines.
Performance Data
Over time, we accumulate data on how each expert performs — Daubert challenge survival, deposition composure, report quality, firm satisfaction. Our matching improves with every engagement.
Rotation Without Risk
Reusing the same expert across multiple cases invites “hired gun” attacks under cross-examination. We maintain the bench depth to rotate experts strategically while keeping quality consistent.
No Hourly Markup
The expert bills your firm directly at their standard rate. Zero markup. This eliminates the discoverable fee structure that opposing counsel uses to attack expert objectivity under Rule 26.

Frequently Asked

Questions Legal Teams Ask Before Engaging

Yes. Marketing is all we do. That specialization is what allows us to match at the subspecialty level — the difference between an SEO expert and a consumer survey expert matters enormously in litigation, and we understand those distinctions because it’s our entire focus. If your case requires a non-marketing expert (economics, engineering, medical), we’re happy to refer you to a service that covers those disciplines.
Within 48 business hours of our initial case briefing. For urgent matters, we can expedite to 24 hours. Each shortlist includes 2–3 candidates with full CVs, testimony history, and a written rationale explaining why each expert’s specific marketing subspecialty maps to your case.
Every marketing expert is evaluated against Daubert’s core criteria: testable methodology, peer review and publication, known or potential error rate, and general acceptance in the relevant marketing discipline. We review their full testimony history for prior admissibility challenges or exclusions. Experts who don’t clear this screening never appear on a shortlist.
Your initial case briefing is complimentary. The search fee is a flat per-engagement charge quoted during that consultation, based on complexity and timeline. There is no markup on the expert’s hourly rate — they bill your firm directly at their standard rate. All fees are disclosed and agreed upon before any work begins.
Yes. We source testifying marketing experts who prepare reports and take the stand under oath, as well as non-testifying consulting experts who advise your team on case strategy and cross-examination preparation — without discovery exposure under Federal Rule of Civil Procedure 26(b)(4)(D).
This is one of the core reasons firms use us. We maintain conflict and availability intelligence across our network. If your ideal expert is conflicted or retained by the other side, we identify qualified alternatives in the same subspecialty — often candidates who aren’t findable through public directories because they don’t actively market their expert witness availability.
Case dynamics change. If a replacement is needed before expert disclosure deadlines, we activate our network immediately and deliver a new shortlist on an expedited basis. Firms on a Case Coordination retainer receive replacement sourcing at no additional search fee.
