Proof Digital

Proof Digital works with B2B manufacturers and construction firms building lead pipelines, CPA firms looking to grow visibility, B2C ecommerce and omnichannel retailers, and nonprofits, from its Indianapolis office and a team distributed worldwide. Founder Stacie Porter Bilger spent two decades before launching the agency working inside Chambers of Commerce and startup-support organizations like the Indiana Venture Center, which shapes the agency's focus on business development alongside marketing execution.

Services run from brand development and strategy through lead generation tactics, local SEO, organic search, paid media (PPC/SEM), and web development. The agency positions these as integrated deliverables rather than standalone projects, aiming each piece toward sales funnel growth for the client's specific business model, whether that's a manufacturer needing B2B leads or an ecommerce operation managing omnichannel demand.

Work is organized around industry-specific goals: accelerating visibility for CPA firms, supporting B2C and manufacturing businesses across multiple sales channels, and building out lead generation systems for construction and manufacturing clients pursuing B2B contracts. Proof Digital also maintains a suite of AI-related digital marketing resources as part of its service offering, reflecting an ongoing effort to fold newer tools into standard SEO, paid media, and web development work rather than treating them as separate specialties.
