The Diamond Group

Based in Wilmington, North Carolina, The Diamond Group is a small marketing agency (team of 1-10) built specifically around custom home builders, home service companies, and solar companies. Rather than serving a broad client base, the agency states it works with a defined set of industries and positions itself as an alternative to hiring an in-house marketing team, aiming to align sales, marketing, and operations into a single system rather than delivering isolated campaigns or tactics. The agency's core offering is the Momentum™ Revenue Growth System, a structured process that reviews a client's current operations, brand presence, marketing channels, target market and personas, and long-term vision before building a growth strategy. Declared services include SEO, content marketing, marketing strategy, web design, branding, and social media marketing, delivered alongside paid advertising campaigns across Google, Meta, and display channels aimed at generating qualified leads and booked consultations. On the sales and operations side, the agency describes setting up CRM systems (including HubSpot), building lead nurture sequences, and streamlining sales processes to help convert prospects into signed contracts. Work is framed around research-based decision-making rather than trend-following, with an emphasis on tying marketing activity directly to revenue outcomes for builders and contractors.
