Lightning Fibre has raised £2,185 for Wayfinder Woman Trust which runs a drop-in centre and safe-space for women at its Eastbourne location.
The charity, run by women, for women, helps those who are feeling anxious and uncertain about themselves or their future.
CEO and Founder, Ben Ferriman, handed over the cheque following several months of fundraising.
Since Summer 2023, Lightning Fibre has run a Pop Up art trail event, as part of the Hailsham Festival, and joined the 2022 Pier2Peer walk, where staff walked from Eastbourne to Hastings Pier in support of the charity.
Ferriman said: "We are happy to support great charities like Wayfinder Woman that work to improve the lives of women in need within our local community."
