Data, engineered for growth.

I'm Bryan Duffin, a business leader, strategist, data engineer and analyst with 15 years in the work. I bring the systems a business runs on into intelligent models, from ads and CRM to operations, projects and finance, then build the insight and automation on top. Valrune is my independent practice.

[ tactics ]

Some of the tactics I've used inside different strategies. Read any of them for the full story.

[ architect ]Identity resolutionThe same identity-resolution work looked different at two scales. For one business, it unified nearly 50,000 identities from fragmented contact records. For a global enterprise, a probabilistic layer connected 98% of the pipeline value missing from the CRM.read the case

[ insight ]AttributionFor one business, moving attribution into the warehouse lifted the monthly won-deal rate 53.4%. For an enterprise funnel, the same shift moved budget out of reach campaigns and into search, where it actually earns its credit.read the case

[ action ]Value-based biddingA BQML model scores each lead by predicted value across roughly 1,100 learned feature categories, so Google's bidder optimizes toward that value instead of raw lead counts. Switching to value-based bidding grew one business's monthly revenue rate by nearly 60%.read the case
