Why 300+ Businesses Exposed a Broken Marketing Model — And the Three-Layer System Built to Fix It
Santa Monica, United States - March 25, 2026 / Joel House /
SANTA MONICA, Calif., March 25, 2026 — Joel House, Founder and CEO of Xpand Digital, a full-service digital marketing agency, has published The Growth Architecture (ISBN: 979-8-295-67501-0), now available in paperback through Barnes & Noble, Amazon, Books-A-Million, and independent bookstores nationwide via Ingram distribution, with international availability through European retailers including Stämpfli Verlag.
The book introduces a structured three-layer framework for building scalable digital growth systems, drawing on House's experience leading marketing strategy that has generated over $96 million in measurable client revenue across more than 300 businesses in 40 industries. The Growth Architecture presents a three-stage model — Foundation, Walls, and Roof — that maps how modern businesses can move from scattered marketing tactics to integrated, self-reinforcing growth systems. The book covers search engine optimization, AI-powered marketing, generative engine optimization, content operations, and agency leadership, offering both strategic frameworks and operational playbooks.
"Most businesses don't have a marketing problem — they have an architecture problem," said House. "They're investing in individual channels without a structure that makes those channels compound. This book is the blueprint I wish I'd had when I started building agencies 15 years ago."
House operates Xpand Digital from Santa Monica, California, where the agency serves clients across legal, music, construction, home services, and e-commerce verticals in the United States, United Kingdom, and Australia. A member of the Forbes Agency Council, House has contributed expert commentary on digital marketing strategy, AI applications in marketing, and agency scaling. The Growth Architecture is his first published book, with a second title, AI For Revenue, currently in production.
The book is available for purchase at Barnes & Noble, Amazon, Books-A-Million, and through bookstores and libraries via Ingram. For bulk orders, review copies, or media inquiries, contact books@joelhouse.com.
