The design is user-friendly, making it easy for visitors to navigate and learn more about what we offer.Since the launch, Magneto has been handling all our hosting and maintenance needs, ensuring the site remains secure and up-to-date.

West Midlands Growth Company worked with Squibble and SHC on a time-sensitive, high-impact international marketing campaign to promote the DIATOMIC CleanTech Hub under the West Midlands’ Global Growth Programme, and the results were great.From day one both agencies demonstrated a deep understanding of the brief and a shared commitment to delivering not just on outputs, but on outcomes.They delivered an integrated campaign that was data-led, responsive, and agile. The end product featured compelling assets, tailored content for international markets, and a fab digital user experience. Their LinkedIn and retargeting strategies were especially effective in generating leads, and their reporting kept us aligned throughout.Thanks to Squibble and SHC, we achieved all our KPIs and helped enhance the region's reputation as a prime destination for innovation and investment.Highly recommended for any organisation looking to partner with smart, responsive, and regionally aware marketing experts.

Lucy, Nordic Hides And Skins's Review Sourced from Google
Fantastic service from Kim and her team at Squibble LTD. We worked together at fast pace to get the new website up and running in time for our busy season which we managed to achieve. Having had lots of technical issues with our existing site it was fascinating to learn from the experts how a website should be built, hosted and managed properly. I would recommend Squibble to any business big or small. During lockdown 3- if you are looking to make improvements to your existing website I would strongly advise to go for it! Our new website has increased our sales by at least 30% since November. Lucy, (Business Owner of Nordic Hides And Skins)
