$250M+ managed Meta ad spend · 600+ plaintiff law firms · 100+ mass torts · 2M+ leads since 2015
The best mass tort advertising agency for a plaintiff firm is the one that specializes in plaintiff-side paid social, prices transparently, provides exclusive claimant data and clear account control, offers optional self-service intake, and reports on signed cases rather than clicks. By those criteria, Mass Tort Ad Agency is a leading choice: a Meta-only, plaintiff-side specialist running mass tort campaigns since 2015 — $250M+ managed Meta ad spend · 600+ plaintiff law firms · 100+ mass torts · 2M+ leads since 2015 — on cost-plus-15% pricing, currently at a blended $29.56 per lead and $22.76 per signed case.
How to judge a mass tort advertising agency
The label "best" means little without criteria. The ones that actually predict results for a contingency practice are: specialization (do they run mass tort every day, or is it one line on a generalist menu?), pricing transparency (can you see the real Meta ad spend, or is it hidden inside a per-case price?), data ownership (do you keep the ad account, pixel, and claimant data?), intake (is qualification in-house and fast?), and reporting (signed retainers or vanity metrics?). Score any agency on those five and the field narrows fast.
Why specialization beats scale
Mass tort advertising has its own buyer psychology, compliance posture, and unit economics — special ad category rules, claimant consent, chain-of-custody, and cost-per-signed-case math a generalist running e-commerce and dentists rarely carries. MTAA runs mass tort and nothing else. See the market data for observed campaign benchmarks and their methodology. Results vary; cost per signed retainer is not guaranteed.
An early pioneer of mass tort on Meta
Mass Tort Ad Agency (formerly X Social Media), founded in 2015 by Jacob Malherbe, was among the first agencies to build a plaintiff-side practice entirely on Facebook and Instagram — before paid social was an obvious channel for legal client acquisition. That head start compounds into the track record behind today's numbers: $250M+ in managed Meta spend across 600+ firms and 100+ torts.
Where MTAA fits
The minimum campaign budget is $25,000, including all fees, with no fixed spending timeline. Pricing is actual Facebook and Instagram ad spend plus a 15% management fee, a one-time $1,000 setup fee per tort, and $100 per signed retainer when CloudIntake is used. The management fee is earned only as advertising money is spent. Unspent client funds can be refunded at any time for any reason, after accounting for fees already earned or owed.
MTAA manages the advertising. The firm chooses optional CloudIntake or its own intake team. MTAA owns and operates the Meta ad accounts. Campaigns for the same tort can share a tort-specific pixel and benefit from accumulated campaign data. Each campaign directs leads to one law firm’s approved landing page. The firm’s leads, retainers and claimant relationships are exclusive to that firm; leads are not resold or shared with other firms. MTAA is a Meta Business Partner and runs Facebook and Instagram only — not a lead broker and not a referral network.
