What Z83 Ag does

Z83 AG is a Swiss fiduciary (Treuhand) and CFO-as-a-Service firm headquartered in Olten, Canton Solothurn, serving startups and SMEs across Switzerland. Founded in June 2020 as Run my Accounts Treuhand Solothurn AG and rebranded to Z83 AG in September 2023, the company employs over 20 qualified professionals — including certified tax experts, certified auditors, CFOs, and accounting specialists — many with University of St. Gallen (HSG) backgrounds. The firm targets a horizontal segment of digital, growth-oriented Swiss SMEs, including a niche practice in crypto-asset accounting, with a secondary offering for solo entrepreneurs and micro-businesses with up to 10 employees delivered in partnership with Infinity.swiss.

The company's service portfolio spans five core pillars: Accounting (bookkeeping, payroll, VAT, financial statements), CFOaaS (process optimization, budgeting, restructuring, valuation, due diligence, succession), Tax (national and international advisory), Audit (via Accosense AG partnership), and IT Consulting (ERP/POS/payment integration). Service delivery is fully digital and paperless, built on Run my Accounts / Infoniqa Business Plus accounting software, Zapier and Make.com workflow automation, DocuSign electronic signatures, and Google Calendar booking. The flagship 2025 product, Z83 × Infinity.swiss, layers AI-powered automated receipt capture and posting on top of Z83's fiduciary oversight for the smallest clients.

Z83 monetizes through a transparent three-tier hourly rate model (CHF 130/h clerical, CHF 160/h qualified accounting, CHF 200/h qualified fiduciary/advisory), billed monthly or quarterly. Approximately 70-80% of service value is delivered by Z83 staff and 20-30% by software. Acquisition is direct and consultative: AI quote generator → free first meeting → digital contract → onboarding, supported by content marketing (German-language blog, SEO), LinkedIn, and event presence (Swiss AI Week, Impact Hub Zurich, Swiss Startup Association). The company is privately held with no disclosed external funding.

Expansion highlights5 records

Direct peers

• KLARA: Swiss tech-enabled accounting and SME platform offering automated bookkeeping, payroll, and integrated Treuhand services. Directly comparable to Z83 in target customer (Swiss SMBs), delivery model (digital + advisory), and pricing approach (subscription + bundled fiduciary).
• Bexio: Leading Swiss cloud accounting SaaS for SMBs, offering bookkeeping, invoicing, payroll and bank reconciliation. Directly comparable to Z83's digital-first accounting offering for the same Swiss SMB and startup target market; differs by being software-first vs. Z83's services-first approach.

Emerging players

• Coresuite: Swiss provider of digital business solutions for SMBs, including integrations with accounting and ERP systems. Comparable as an emerging tech-enabled player in the Swiss SME financial / operational software stack that Z83 helps implement through its IT Consulting service.
• Taxgate: Swiss tax software and advisory platform for individuals and small businesses. Comparable because it bundles tax preparation with advisory support in a digital format, competing with Z83's Tax Services line for digital-native Swiss customers.

Broad incumbents

• Treuhand Suisse: Swiss professional association and large network of fiduciary / Treuhand firms serving SMEs and individuals. Comparable as the dominant traditional incumbent in Z83's core fiduciary market; competes for the same SME/startup clients but typically with less digital delivery.
• Abacus Research: Established Swiss ERP / business software vendor with accounting, payroll, and financial planning modules. Comparable because Swiss Treuhand firms (including partners and competitors of Z83) implement and resell Abacus for SME accounting; represents the broader enterprise-software incumbent side of the market.
• PwC Switzerland: Big-4 professional services firm in Switzerland offering audit, tax, and advisory services. Overlaps with Z83 on Tax Advisory, Audit (Z83 partners with Accosense), and CFO advisory for growth-stage Swiss companies; competes at the higher end of the SMB/startup segment.
• EY Switzerland: Big-4 firm with significant Swiss tax, audit, and transaction advisory practice. Comparable to Z83 for startup and SME clients needing tax structuring, due diligence, and CFO-level advisory; competes at the larger end of Z83's addressable market.
• Infoniqa (Run my Accounts): Swiss provider of business software including the Run my Accounts / Infoniqa Business Plus accounting platform that Z83 uses. Comparable because it serves the same accounting/CFO buyer with overlapping capabilities; Z83 is a partner rather than direct competitor but represents the broader incumbent platform Z83 competes against at the service layer.

Regional players

• MoneyPark: Swiss financial services platform focused on mortgage and financing advisory for individuals and SMEs. Comparable as a Swiss digital financial advisory that competes for similar SME/startup mindshare and CFOaaS-adjacent financing work.
