What Selesti does

Selesti is a UK-based digital marketing and web design agency operating under the legal entity The Definitive Agency Ltd (company number 12256648), founded in 2005 and headquartered in Norwich with a regional office in London at 199 Bishopsgate. The firm delivers consultancy, design and build, and digital marketing services to a client base spanning financial services (Barclays, AXA, Zoopla), insurance (Lexham Insurance), healthcare (King Edward VII's Hospital), retail (Jewson, Duracell, Pets at Home), sports (Norwich City FC, Aviva), hospitality (Soho House), and mid-market consumer brands (Funkin Cocktails, Winsor Bishop, Learning Resources). Selesti employs between 11 and 50 staff and holds a distinctive dual certification as both a B Corporation and Google Premier Partner — a combination the company claims makes it the world's only B Corp Google Premier Partner, alongside memberships in 1% for the Planet and the Slave-Free Alliance.

The agency's core offerings span Magento eCommerce builds and migrations (notably Magento 1 to Magento 2), WordPress/CMS implementations, custom mobile application development, technical SEO and penalty recovery, paid search management on Google Ads, social media marketing, content strategy and earned media/link building. Technical capabilities rest on certified Magento developer expertise, an Agile two-week sprint delivery methodology with an MVP approach, enterprise SEO tooling (SEMrush, Majestic, Linkdex, ScreamingFrog), and bespoke CRM/ERP integration work. The firm has accumulated more than 60 industry recognitions over 14+ years including European Search Awards, Drum B2B Brave Awards, BIMA, and Interactive Media Awards.

Selesti's business model combines project-based design and build work — typically fixed-price for eCommerce builds and website redesigns — with recurring retainer-based digital marketing services (SEO, PPC, social media, content) and ad-hoc consultancy/training engagements. Pricing is bespoke and quote-based with no publicly disclosed tiers and multi-year contract cadences on enterprise accounts. The go-to-market motion is sales-led and relationship-driven, combining direct outreach from the Norwich and London offices, co-branded masterclass events at Norwich City FC's Carrow Road stadium, and inbound lead generation through the company's Knowledge Hub content platform and case-study marketing. Distribution is UK-domestic only, with the London office providing access to enterprise accounts and the Norwich headquarters anchoring regional mid-market clients and ESG-aligned growth following B Corp certification.
