Prysm

What Prysm does

Prysm is a privately held Swiss fiduciary (fiduciaire) founded in 2004 by Michel Thomas in Lausanne, Vaud canton. The firm delivers three integrated service lines: Tax Strategy Services (tax returns, simulations, medium/long-term planning, estate and relocation advisory, and tax negotiations with cantonal authorities), Payroll & HR Services (outsourced salary processing, HR administration, employment law advisory, work permits, and pension administration supported by a secure online employee portal), and Accounting & Finance Services (bookkeeping, year-end closing, VAT compliance, financial analysis, and new business formation support). Tax specialists are embedded across all three service areas to align compliance with tax optimization for clients with complex or international situations.

The firm operates without a disclosed proprietary technology platform, relying instead on professional expertise, a bilingual French/English web presence, content marketing through educational tax articles, and word-of-mouth referrals reinforced by long-tenured enterprise client testimonials (notably Nespresso's CEO endorsing Prysm after a 15-year relationship). Prysm serves 180+ businesses across diverse industries including Nestlé subsidiaries, Skechers, Coface, Fyffes International, and Reitzel Group, with a stated focus on companies and individuals facing complex or international tax situations within Switzerland.

Commercially, Prysm operates a sales-led, relationship-driven GTM with customized per-engagement pricing, no publicly disclosed fee schedules, and direct client consultation from its single Lausanne headquarters at Grand-Pont 8. The firm has been bootstrapped since inception with no external funding rounds, no disclosed M&A activity, and a stable four-person leadership team (Thomas, Nilson, Thiberge, Yarminyan) that has largely been in place since 2008. The ownership structure appears to be founder-controlled, consistent with the traditional Swiss fiduciary practice model.

Broad incumbents

• PwC Switzerland: Big 4 firm providing tax, legal, HR, and payroll advisory across Swiss cantons. Comparable as an alternative provider for Prysm's enterprise clients needing cross-border tax and payroll services, with much broader geographic and capability coverage.
• BDO Switzerland: Global mid-tier audit and advisory firm with a significant Swiss presence offering tax, accounting, and payroll services. Comparable as a direct competitor for Prysm's enterprise clients seeking cross-border and Vaud tax expertise, though at much larger scale and broader service portfolio.
• KPMG Switzerland: Big 4 firm with a major Lausanne and Geneva presence serving large multinational clients in Switzerland. Comparable for high-end international tax work that overlaps with Prysm's enterprise segment, though at significantly larger scale and broader portfolio.
• Deloitte Switzerland: Big 4 firm with extensive Swiss tax and payroll practice serving multinational subsidiaries. Comparable as competitor for Prysm's enterprise client mandates involving international mobility and Swiss compliance.
• EY Switzerland: Big 4 firm offering tax, people advisory, and transaction services in Switzerland. Comparable for international tax planning, expatriate taxation, and payroll — areas where Prysm serves enterprise clients such as Nespresso and Fyffes.

Direct peers

• Mazars in Switzerland: International audit, tax, and advisory firm operating in Switzerland with a similar mid-market focus. Comparable because it serves multinational subsidiaries and complex international tax situations across Swiss cantons — directly competing with Prysm's niche.
• OBT AG: Swiss-based fiduciary, tax, and audit firm serving SMEs and mid-market clients across German-speaking Switzerland. Comparable as a similarly positioned Swiss fiduciaire with multi-disciplinary service lines and regional specialization.
• Grant Thornton Switzerland: Global mid-tier accounting network with Swiss operations providing tax, audit, and advisory services. Comparable in serving internationally active SMEs and subsidiaries of multinationals with cross-border tax complexity.
• Baker Tilly Switzerland: Mid-tier accounting and advisory network with Swiss offices offering tax compliance, accounting, and HR/payroll outsourcing. Closely comparable to Prysm in service mix, target segment (mid-market enterprises and international subsidiaries), and Swiss market focus.

Regional players

• Trianon SA: Swiss fiduciary and tax advisory firm focused on the Lake Geneva region (Vaud/Geneva). Comparable as a regional fiduciaire serving similar client profiles — businesses and high-net-worth individuals with complex international tax situations in French-speaking Switzerland.
