Case Study: First Hawaiian Bank achieves faster activation and higher audience addressability with Amperity

Innovating advertising for faster, smarter campaigns

First Hawaiian Bank was struggling with long lead times and low accuracy for paid campaign activation — a 26‑day upload process and reliance on outdated identifiers produced only 40–60% match rates. To modernize their identity strategy and improve first‑party audience addressability, they partnered with Amperity, leveraging Amperity’s unified customer data foundation and a co‑developed connector to The Trade Desk.

Amperity co‑developed The Trade Desk direct connector using Unified ID 2.0, letting First Hawaiian Bank activate precise customer segments faster and suppress irrelevant audiences. The work drove measurable gains: >90% match rates, +92% faster activation, and +94% average audience addressability across multiple segments — while avoiding another vendor relationship and positioning First Hawaiian Bank as an industry pioneer.
