Colorado's PR market is anchored in Denver but increasingly reflects a statewide technology economy that has grown substantially over the past decade. Denver is one of the fastest-growing major metros in the United States, and its PR landscape mirrors that growth: technology and SaaS, outdoor and lifestyle brands, cannabis (Colorado was first), healthcare, real estate, and a strong nonprofit and public affairs sector tied to state government.
Boulder adds a distinct layer — a startup and venture ecosystem with disproportionate density relative to its size, producing tech, consumer, and wellness brands that regularly need communications support.

Public Affairs: State government, energy policy, water rights, and healthcare policy create steady public affairs PR work in Denver, particularly for firms with Colorado legislative relationships.
Frequently Asked Questions
Which is the leading PR firm in Denver? There is no single dominant independent the way Houston has Pierpont or DPW PR. Denver's market is fragmented across strong boutiques and specialty firms. SideCar PR leads in real estate communications; Sigler and Novitas lead in corporate and financial communications.
What sectors drive PR demand in Colorado? Technology and SaaS, real estate and development, outdoor and lifestyle brands, cannabis, healthcare, nonprofit and public affairs, and the growing financial services and fintech sector in Denver.
Is Boulder a separate PR market from Denver? For practical purposes, Boulder is a satellite of Denver — most Boulder startup clients use Denver agencies or national firms. A handful of boutique agencies operate in Boulder itself for the startup and wellness brand market.
Do national firms serve Colorado clients? Yes. Edelman, Weber Shandwick, and the major network agencies serve large Colorado clients from national platforms. For local media relationships and state government affairs, Colorado-based independents typically deliver stronger results.
