How We Work Let's TalkLed by Jamie Marshall.
15+ years of development experience. Billions in media spend executed. Some of the world's biggest marketing operations, delivered.
Jamie Marshall began his career in small publishing firms, where he developed technology for the entertainment industry in Hollywood, CA before moving to WPP - the worlds largest media agency. Under the operating group Mediacom he worked in data analytics and strategy development for many fortune 500 brands including Playstation, AB inBev and Volkswagen Audi. He was part of the launch of Ring Doorbells in partnership with Bain Capital - which sold out in 6 months with orders for another year. He helped develop the go to market initiative for Pokemon Go which became a global phenomona.
Jamie has built professional DMP, and delivery operations in AWS, serverless, and big data systems like spark and glue for many agencies. He brings with him a number of practices and strategies that allow him to develop fast while keeping projects on track as they scale and without burning time on infrasturcture that never goes to market.
What is the secret to success? It's those 15+ years in software engineering and data science that allow him to look into operations and market performance, producing solutions that give companies market advantages. For companies under 50M, he's seen growth and integration at emerging companies so often there is a strong roadmap. He has a keen sense of what technology and operating procedures drive growth at your size, and can fit the proper tech stacks to your goals.
His work spans the full spectrum of modern marketing and technology: architecting big data analytics systems for global agencies, building AI-powered tooling for call center operations, designing acquisition strategies for iconic consumer brands, and helping smaller businesses streamline, compete, and win.
Brands & Agencies We've Worked With
What We Build
We design and build analytics systems that ingest millions of rows, normalize fragmented data sources, and surface real-time insight through dashboards and APIs. Built on AWS Glue, Athena, DynamoDB, and Parquet — fast enough to actually drive decisions.
We've executed billions in media spend across TV, Advanced TV, and digital channels. We build the measurement infrastructure that tells you which dollar is working — and the models that tell you where the next one should go.
From AI-powered sales call review (using AWS Connect + OpenAI) that flags brand-damaging conversations with 80% accuracy, to custom ML pipelines and LLM integrations — we build AI systems that solve real operational problems, not demos.
End-to-end product development using modern serverless architecture on AWS. We've taken full analytics platforms from zero to production in under 60 days. No bloated R&D cycles — just working software in production, fast.
Signature Work
Built a full analytics platform for a major media client tracking over $10M in linear TV spend. Designed to surface performance gaps in real time, enabling buyers to shift dollars within hours rather than weeks. Delivered under budget using serverless AWS infrastructure and AI-assisted development workflows.
Designed and deployed a call center intelligence layer using AWS Connect and OpenAI that automatically flags the riskiest agent calls for supervisor review. Reduced time management spent manually listening to calls by an order of magnitude and identified brand-damaging conversations at 80% accuracy.
At MediaCom, built automated reporting infrastructure across $3B+ in annual digital media spend for global clients. Replaced multi-day manual reporting cycles with automated pipelines delivering daily — enabling faster optimization and better campaign ROI across the board.
Led the full technology transformation at Bandz Inc — from legacy industrial control systems (C++, IEC 61131-3) through AWS cloud migration. Improved production uptime, reduced operational overhead, and introduced data-driven operations management to a traditionally analog environment.
Jamie took a complex multi-source data problem we'd been struggling with for two years and had a working pipeline in production inside of a month. We stopped guessing about our media performance the day it launched.
