Why use Voucher Magpie?
Every Sialph code here comes from Sialph itself or its official affiliate programme, never copied from another voucher site. When you shop through our links, Sialph may pay us a commission. It never changes your price. We give 50% of that commission to the charity, club or school you choose, at no extra cost to you.
About Sialph
Sialph is a UK venture-building business run by Simon Phillips and operated by Sialph Limited, a company registered in London. It is aimed at founders, start-ups and established small businesses rather than consumers, and mixes paid advisory work with a directory of partner tools and finance options. Sialph states that it is not regulated by the Financial Conduct Authority, does not give investment or financial advice, and may earn commission when users take up partner services.
Its own services include an Initial Consultation, the Startup Sprint (a short, hands-on accelerator for early-stage tech founders, currently open to UK businesses only) and a four-hour Micro-Accelerator for Startups. Founders can also join the Sialph Venture Circle, a members' network where businesses submit monthly progress updates and 'deal memos', and the team looks for introductions to funders, partners, buyers and workspace.
The shop also lists more than a hundred partner products, from accounting and payments platforms to advertising, recruitment, e-signature and AI tools, plus business finance routes such as invoice, asset, bridging and revenue-based finance. Many listings are free referrals with a partner discount or credit attached, such as a Bolt Business ride discount or Reddit advertising credit. Refunds on Sialph's own services follow a limited policy, so check what's included before you pay.
