Radiant Elephant is a boutique, owner-led web design, SEO, and advertising agency based in Northampton, Massachusetts, founded 13 years ago by Gabriel Bertolo, a third-generation entrepreneur. Gabriel personally leads every client account with no handoffs to project managers or junior staff, functioning as a dedicated VP of Marketing for each business he works with. The agency specializes in conversion-focused WordPress web design and development, Search Engine Optimization, Generative Engine Optimization (AI SEO), digital advertising (Google Ads and Meta), Conversion Rate Optimization, and brand identity design. Every service is built around one goal: measurable revenue growth. What sets Radiant Elephant apart is a rare combination of deep technical expertise and genuine ownership mentality. Gabriel was an early pioneer in Generative Engine Optimization, helping clients rank inside ChatGPT, Perplexity, and Google AI Overviews at a time when most agencies had not yet taken notice.

With a 90% client retention rate and clients averaging 6+ years with the agency, Radiant Elephant has been featured in Forbes, Entrepreneur, Business Insider, HubSpot, and Shopify.
