Linear (sometimes listed as Linear Design) was founded by Luke Heinecke (CEO) in Sandy, Utah, and operates as a specialist PPC and conversion rate optimization agency rather than a generalist full-service shop. The origin story is positioned around an in-house CMO who was tired of standard agency experiences and built Linear to operate the way a dedicated internal team would, with flat-fee pricing, no long-term contracts, no extra billing for ad spend increases, and full client ownership of ad accounts and creative assets. The agency combines its in-house team of specialists with a proprietary AI layer called Pixis, which surfaces patterns and budget recommendations across Meta, Google, and LinkedIn that account managers review before deploying. Every client is assigned a dedicated account manager who works directly with the brand, replacing the typical strategist-to-junior-executor handoff. Published client logos include Coca-Cola, DHL, Domino’s, Betabrand, Klar, and Vector, alongside more than 20 detailed case studies across SaaS, healthcare, legal, home services, and ecommerce verticals such as Nextbite, Penji, BairesDev, Ahara, EnviroKlenz, Paver Supply Warehouse, and Laree Co.
