Overview

About Passion Digital

Passion Digital is a 30-person London search agency in Holborn, founded in 2012, that divides its work between SEO and paid media, including Google Ads, paid social, programmatic and Amazon ads. It works mostly with B2B, professional services, property, finance and charity clients who want organic and paid search managed together.

Passion Digital was founded in London in 2012 by Mike Grindy and works from Holborn Tower in WC1. The team numbers about 30 specialists, led by Managing Directors Owen Osztotis and Cecilia de la Viesca, with separate heads of organic search and paid media. The agency now sits within Stellar, a performance network built around the Pixis AI platform, while continuing to trade under its own name.

The agency calls itself search-led, and Clutch data backs that up with an even 50/50 split between SEO and PPC. On the organic side it covers technical audits, site migrations, content, local and international SEO, and AI search work such as tracking how brands appear in large language model answers. Paid media spans Google Ads and Shopping, programmatic and connected TV, Amazon and retail media, and paid social across Meta, LinkedIn, TikTok, Reddit and YouTube. Running both under one roof lets the team shift budget between organic and paid keywords.

Its client base leans towards B2B and considered purchases. Knight Frank, Octopus Investments, Shoosmiths, OneTrust and Mazda appear on its site, and Clutch reviewers include serviced apartment firm SilverDoor and charity Action Medical Research. The agency reports a 1,420% rise in lead volume for Knight Frank and a 425% increase in paid leads for Cloud Gateway; those figures are self-published. It won at the UK Paid Media Awards in 2024 and the UK Search Awards in 2022 and 2023.

Thirty-three Clutch reviews average 4.7, with praise for knowledge, responsiveness and value. Recurring criticisms are a slow start while the team learns a new sector, and fewer check-ins once accounts mature. For a mid-market London SEO and PPC agency, Passion Digital is credible and well reviewed; its size is the main limit for very large accounts.
