Case Studies

Our client impact in action

One question, one expert, booked in seconds

Lux Research's clients waited to reach the analysts who wrote the research: 75% of inquiries took more than seven days to schedule. FullStack built Luxer, an AI assistant that answers from Lux's own library with citations, maps the topic to the right expert, and books the meeting. Now 35% schedule inside 48 hours.

A governed data layer under the marketing surface

A Fortune 500 hospitality leader's guest experience ran on a backend-for-frontend layer with duplicated content and no data governance, leaving downstream AI nothing trustworthy to reason from. FullStack rearchitected it as a governed data access layer, migrating Hero Offers, Reserve Offers and Marketing Rooms, and built the pipelines now feeding retrainable models and guest-facing AI.

Agentic routing that escalates instead of guessing

A regulatory compliance provider needed call review at a scale humans couldn't reach. FullStack built an agentic system that sorts each sentence by issue type, routes it to the right model without a human prompt, and surfaces a ranked report. Reviewers went from 500 sentences per call to 5, at 93% accuracy — parity with human auditors.

A live workflow in 6–8 weeks *

Process mapped in one to two weeks, then one workflow running on real cases — not a demo on our data.

Measured from a Week 0 baseline

We record what the workflow costs in time and money before anything changes. Without that number, nothing afterwards is provable to your CFO.

We build the systems, not the campaigns

We're not an ad agency. No media buying, no creative, no campaign management. We build what your marketing runs on and hand it back to your team.

Not every workflow qualifies

Agent-ready work has volume, repetition, reachable data and low judgment density. If a process fails those tests, the mapping will say so — that's a useful answer, not a failed engagement.
