A product millions loved.
No engine to scale.
Trim had 2M+ users and a strong product suite: subscription cancellation, bill negotiation, and high-yield savings. But marketing ran in-house with no systematic paid media infrastructure. Down-funnel CPA sat at $22 to $25 with no path lower.

No tracking

No full-funnel attribution in place. No way to measure down-funnel CPA or optimize beyond surface-level metrics.

Legacy landing page

Unoptimized multi-step flow with redundant form fields, poor mobile experience, and no A/B testing framework.

Ad hoc creative

No structured creative pipeline. No systematic testing cadence. Performance creative was an afterthought.

Minimal affiliates

Affiliate channel barely stood up. No publisher-level monitoring, no premium placement negotiation.


Full-stack acquisition.
Built from zero.
  • Phase 01
    Full-Funnel Instrumentation
    Before any spend went live, Growthr instrumented the entire funnel: land, click, signup, Free Trial, Bank Account Connect, paid subscription. Every event verified across Google Ads, Facebook, and internal analytics. Down-funnel CPA optimization from day one.
  • Phase 02
    Site Rebuild and Conversion Architecture
    New Webflow landing page replaced the legacy multi-step flow with an email-gate to OAuth bank-connect sequence. Redundant fields removed, CTA hierarchy simplified, mobile rebuilt from scratch. A/B tests run through Google Optimize, tracked via Heap Analytics.
  • Phase 03
    Weekly Creative Sprints
    New UGC-style video and static concepts every 7 days, evaluated on down-funnel CPA, not CTR. Losers paused immediately, winners iterated. Phone-shot UGC hooks with benefit-first captions consistently outperformed polished brand creative. CTR on winning formats ran 3x above static baselines.
  • Phase 04
    Scale and Cohort Optimization
    Daily bid reviews against CPA targets. Optimization event shifted progressively from Free Trial to Bank Account Connect as data matured. 91.3% of BAC users converted to paid trial, making it the north-star metric. Budget split by age, HHI, device type, and OS.

Four engines.
One acquisition machine.

Google Search Search

Non-brand intent capture on subscription cancel, bill negotiation, and related queries. Broad match with aggressive negative matching. Mobile vs. desktop device-split optimization.

$4.06 best CPA on signup event

Meta Social

Interest and lookalike prospecting, CBO structure, Special Ads Category compliance for financial products. Android-only campaigns and desktop/mobile split testing.

$13 top creative CPA

Affiliates CPA

CPA-based payouts across Fluent, SheIsMedia, AragonAds, Chime, Varo, TapJoy, and Brigit. Premium placement negotiation. Publisher-level fraud monitoring.

$4/BAC TapJoy peak efficiency

Email / CRM Lifecycle

BAC drip with 71% open rate and 36% CTR. Abandoned Cart sequence with 97%+ CVR from first open. Lifecycle architecture built around bill negotiation and bank-connect milestones.

18.3% BAC drip CVR

Metrics that drove
an acquisition

From $5K/month to $50K+/week at peak, ROAS held above 100% throughout. Every dollar of spend was traceable to a down-funnel event. 30+ ad batches, audience segments, and bidding structures were built and handed off as a durable operational asset.
