Chesterfield Digital Marketing Agency Supports Over 150 Businesses Since Launch

David and Abbie Coslett, Co-Founders of Hello Social Avenue, have hired a full-time team for their social-first digital marketing agency after a period of significant business growth and client wins, which saw business turnover grow by 74%.

The duo, who got married in 2021, started the business from their kitchen table in January 2023, utilising their previous experience working in digital marketing and social media careers. They offer a range of marketing services for businesses, including content marketing, digital marketing strategy, social media support, video production and editing, and marketing training and courses.

They were fortunate to receive two grants towards their initial business startup costs, to help with purchasing equipment for the studio, based in Chesterfield’s Clowne Business Centre.

Within three months of launching, customer demand for Hello Social Avenue’s services grew exponentially, and the agency owners hired two full-time members of staff, a Head of Client Success and a Videographer. They were later joined by a Business Development Manager and Social Media Videographer, who will support the agency’s roster of clients, including Bolsover District Council, ActionCoach Sheffield, Anderson Entertainment, Stancliffe Homes, and Dalton Roofing.

Before entering the world of marketing, David worked in the music industry, performing gigs up and down the country as a singer and songwriter, launching an EP album that reached number seven on the iTunes charts. He attributes much of his musical success to digital marketing, and spent a large proportion of his time as an artist building a community, nurturing relationships and growing a social media presence.

Co-Founder, David Coslett, explains,

“One of my most important marketing questions came from playing in an empty room. I’d hired venues that were far too big because I assumed the audience would come, and they didn’t. I realised I needed to build audience interest, scale slowly and build a community of fans that loved the music, and that’s when everything changed. I lived and breathed marketing when I was working in music, which sets me apart. I was actually doing it and seeing it was working.”

“Hello Social Avenue started with a vision to remove the guesswork from marketing, and it’s grown into a business built on trust, results and relationships. Our turnover increased by 74% in 2025, and we are honoured to have supported over 150 businesses through strategy, content, events, and training."

“As we continue to evolve, one thing has become clear, the next stage of the business isn’t about doing more ourselves. It’s about bringing in the right people to do it better.”

David and Abbie have big plans for their business in 2026. They are launching a new CRM platform for service-based businesses to simplify their marketing, and will be hosting several online and in-person events to support more people with their digital marketing and social media.

Their next event is a Marketing Mixer that will take place in May, with guest speakers Katy Leeson, Growth Mentor and ex Managing Director of Social Chain, and Ben Hacker, Co-Founder of Content Jungle. To top it off, they’ve recently been ranked #65 in the Elite Business Top 100 SME Businesses for 2026.
