What SI Capital does
SI Capital Ltd is a UK boutique stockbroking and wealth management firm headquartered in Godalming, Surrey, with a regional office in Mayfair, London. Founded in 2004 by Renato Rufus, the firm is FCA-authorised and a Member Firm of the London Stock Exchange, serving three primary client groups: private individuals and high-net-worth clients, small-cap companies listed or planning to list on the London Stock Exchange (particularly the AIM market), and intermediary/professional investors. The firm operates with a relationship-driven, high-touch model delivered through face-to-face meetings, telephone consultations, and a 24/7 client portal launched in November 2024.
The firm's product surface spans private client services — Discretionary Portfolio Management, ISA Services, SIPPs and SSASs, Inheritance Tax Portfolios (using Business Relief-qualifying AIM shares), Estate Planning, IPO and Placing access (minimum £5,000 ticket), and Advisory Stockbroking — alongside Corporate Broking (IPO flotations, equity and debt fundraisings, share price monitoring) and an Intermediary/ETF-based Managed Portfolio Service. Corporate research is delivered through a partnership with Progressive Equity Research rather than an in-house team. Leadership includes a CIO with 40+ years of experience (ex-Goldman Sachs, ex-Caxton Associates) and corporate broking staff with 30+ years each.
Revenue is generated through a mix of recurring advisory and management fees (private client mandates, MPS), transaction-based commissions (share dealing, IPO/placing participation), and episodic corporate advisory and success fees (IPO flotations, primary/secondary fundraisings). Pricing is bespoke and quote-based rather than published; no fee schedules are publicly disclosed. Distribution is exclusively direct: all services are delivered by SI Capital's investment managers, brokers, and corporate team through offices in Godalming and Mayfair, supported by telephone, virtual consultations, and the client portal — with no third-party resellers or marketplace channels.
