The Design Business Index (DBI) is a merit-based rating system and professional directory founded to address one of the design industry’s biggest challenges: the difficulty of reliably assessing a designer’s true capabilities before a project begins. Through its partnership with the internationally recognized A’ Design Award, DBI combines a rigorous blind review process with transparent evaluation criteria to transform subjective design quality into objective credentials. By featuring only those who have demonstrated excellence under these stringent standards, DBI ensures a carefully curated pool of top talent, where clients can make confident, data-driven decisions about creative partnerships.
Beyond its directory, DBI offers a comprehensive DBI Credibility Suite™ designed to help designers and studios stand out in an overcrowded market. Each DBI-rated professional receives authoritative certificates, digital assets, and rating logos that validate their skills and attest to their proven creative excellence. These tools seamlessly integrate into websites, social media, and marketing materials—reinforcing trust, credibility, and, ultimately, market value. Notably, DBI ratings remain valid for a two-year period, encouraging ongoing professional development and highlighting those who continuously push the boundaries of innovation.
By systematically reducing guesswork and eliminating reliance on subjective portfolio reviews alone, the Design Business Index creates a more efficient, trustworthy, and merit-based environment for both clients and designers. With DBI, top talent rises above the noise, clients gain peace of mind, and the entire global design community benefits from higher standards of creativity, innovation, and professional excellence.
Design Business Index champions design excellence, valuing official recognition from respected international juries over mere popularity. Our criteria focus on transparent, rigorous evaluations by peers, assessing quality, ethics, and innovation. Notably, the prestigious A' Design Award highlights truly exceptional projects, judged by academics, press members, and professionals using a documented scoring system. We exclusively feature professionals and studios that have earned at least one peer-reviewed award, particularly the A' Design Award, ensuring that our listings represent meritocratic accomplishment, innovation, and credibility.
