Flex's Marketing Data and Compliance Orchestration: Consent-Gated Tracking Across Web and App

Flex provides financial services to renters and their landlord partners. This engagement served its growth, marketing, website, and product analytics teams, rebuilding how the company tracked and measured user behavior across its web and mobile platforms.

The company was flying blind: no process for shipping website changes or spinning up landing pages, no proper way to track metrics on the site, and no real platform for running ads. The site lived on a slow, clunky WordPress install costing $2,000 a month; marketing integrations (pixels, Amplitude, Singular) were essentially absent; and consent and cookie management had not yet been put in place, which a fintech needs before it can track anything at scale. The team was losing data, unable to understand user and partner behavior, and slow to ship experiments.

Taller rebuilt the foundation across two years: migrating the site from WordPress to Webflow, standing up a dedicated Unbounce stack for paid landing pages, and building an AWS-hosted orchestration layer that tied the marketing vendors together, pulling data from each vendor, normalizing it, and feeding it into Google Tag Manager, which decided which events fired and where they went. All tracking was gated by consent managed through Transcend, and the website and mobile app were linked so the same user stayed consistent across both environments. Along the way the engagement delivered two full rebrands and a fixed request-and-feedback workflow for the marketing team.
