Some £20,000 of savings and loans initially took the deodorant from concept to reality: Kennedy worked with a cosmetics scientist, coming up with 40 deodorant formulations: “Testing started off very crudely — lots of sniffing our armpits and measuring damp patches with napkins – now we have external sniff tests and a bacteria incubator to prove it is effective for 24 hours vs benchmarks.” Fussy launched on Kickstarter in October 2020. That campaign pre-sold £100,000 of deodorant in 30 days, “with no marketing spend,” Kennedy points out. A £470,000 pre-seed round, partly via a beauty accelerator platform, led to him quitting corporate life to work on Fussy full-time.
