Semperfli

What Semperfli does

Semperfli (legal entity: Semperfli Fly Tying Materials Ltd.) is a UK-headquartered manufacturer of advanced fly tying materials, founded in 2010 and operating from Selby. The company designs and produces a broad catalog of threads, dubbing, synthetic fibres, flash materials, predator fibres, wires, beads, foam bodies, and related components used by fly tyers to construct artificial fishing flies. Its technical differentiators centre on proprietary GSP (gel-spun polyethylene) thread chemistry (marketed as Nano Silk, available in seven deniers from 10D to 300D), computerized pressure dyeing for repeatable colour consistency, and non-tarnishing wire coating. The product line is complemented by distributed third-party brands, most notably Japanese hook and tool maker Tiemco.

The company monetises through a hybrid go-to-market: direct-to-consumer e-commerce at semperfli.net (priced in GBP, USD, EUR, and CAD), a dedicated USA B2B trade portal (semperfliusb2b.com), bulk/wholesale contracts for commercial tyers and factories, and a worldwide authorized dealer and distributor network. Unit pricing is modest (most SKUs $3–$10, with collection and dispenser boxes reaching up to ~$77), implying a high-volume, low-AOV consumables model. UK manufacturing origin yields tariff advantages into the US, Canada (under the UK-Canada trade agreement), and Europe, supporting direct cross-border DTC reach into 40+ countries.

Semperfli serves a hybrid segment mix spanning hobbyist and professional SMB fly tyers, commercial tyers, fly tying instructors, international competition anglers, specialist retailers, and fishing guides. The company has earned external validation through the 2022 Queen's Award for Enterprise: International Trade and the 2023 AFFTA Best Fly Tying Material award. Customer-facing channels combine content marketing (extensive technique blog), email, organic social, a sponsored Pro Team of anglers, and a regional pop-up roadshow programme across the UK. The company is privately held, bootstrapped (no funding rounds disclosed), with Andy Kitchener listed as Director and a headcount in the 51–100 range.
