Influencer marketing that actually makes sense
The best influencer campaigns do not start with follower counts. They start with the right creator, the right audience and the right message.
We help brands plan, negotiate and deliver creator partnerships that feel natural, perform properly and protect the trust between creator and audience.
Whether you need a YouTube integration, dedicated review, Instagram campaign, TikTok partnership, podcast sponsorship or long-term ambassador deal, we help build the campaign around the outcome that matters.
What Colossal Influence does
Influencer marketing campaigns
We help brands build campaigns around audience fit, creator credibility and clear commercial goals.
That can include creator sourcing, outreach, negotiation, briefing, content review, reporting and ongoing campaign management.
Our campaign history includes work with Chelsea FC, Amazon Prime Video and MyProtein / THG, a long-running LELO relationship spanning 30 creator campaigns, and repeat creator partnerships with brands including FlexiSpot and Beducated.

YouTube sponsorships
YouTube is one of the strongest platforms for influencer marketing because audiences build long-term trust with creators.
We help brands secure YouTube integrations, dedicated videos, pinned comments, description links, Shorts, community posts and wider multi-platform sponsorship packages.
Influencer talent management
We represent a select roster of creators and help them manage sponsorships, brand partnerships and long-term commercial opportunities.
We focus on deals that fit the creator, protect the audience relationship and build sustainable income.

If you need expert guidance before spending budget, we can help with creator shortlists, pricing, campaign structure, usage rights, contracts, sponsorship packages and long-term influencer strategy.
Why brands work with us
Colossal Influence understands both sides of the creator economy.
Brands need creators who fit the campaign, communicate professionally and deliver content their audience will actually care about.
Creators need fair deals, clear briefs and partnerships that do not damage the trust they have built with their audience.
We sit in the middle, helping both sides build better campaigns.
We look beyond surface-level numbers and consider audience demographics, average views, engagement quality, comment sentiment, brand safety, platform fit, past performance and commercial value.
Our creator roster
Colossal Influence works with creators across commentary, entertainment, lifestyle, gaming, beauty, fashion, fitness, nostalgia, true crime, ASMR and sports.
Our roster includes creators with strong audience relationships, distinctive content and clear commercial potential.
