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 $109.76 per qualified lead and $322.39 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. In the most recent 30-day window, MTAA tracked $983,667 in mass tort ad spend at a blended $109.76 per qualified lead and $322.39 per signed case across 8 active tort campaigns. Those figures update continuously from live data — see the live cost per signed case.
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
MTAA prices at cost plus a flat 15% management fee — you see the actual Meta ad spend and add 15%, with a one-time $1,000 setup per tort and CloudIntake screening billed at $100 per signed retainer. No inflated cost-per-case markups, no resale, no minimum-spend tricks.
Media buying and intake are both in-house, so when a tort heats up the ads and the screening scale on the same day. The firm owns the ad account, pixel, creative, and claimant data. MTAA is a Meta Business Partner and runs Facebook and Instagram only — not a lead broker and not a referral network.
