Sergio R.

I’m a Chartered Accountant specializing in startups, crypto, and Swiss & international taxation. My focus is on clients who need more than bookkeeping — they need a strategic partner to ensure compliance, optimize tax exposure, and bring financial clarity. I specialize in working with crypto and digital companies, tech / AI / robotics startups, and trading firms, including proprietary trading firms and HFT environments. Services: • Advanced tax planning & structuring (personal & business) • Crypto accounting & taxation (portfolio tracking, compliance, reporting) • Startup advisory (entity setup, financial models, reporting) • High-level accounting & financial analysis I work with clients who value precision, discretion, and efficiency, and who are looking for a trusted advisor to handle complex financial matters. If you need top-tier accounting and tax expertise to match the pace of your business, let’s connect.
