ESN Partners

What ESN Partners does

ESN Partners is a privately-held chartered accounting and business advisory firm headquartered in Sydney, Australia, operating from two locations (Sydney CBD and Woolooware). Founded in 2011, the firm employs approximately nine to ten professionals across partner, consultant, manager, senior accountant, accountant, and practice administration roles, with three named partners (Evan O'Rourke, Abby Pinn, and Scott Brown) and dedicated specialist coverage including SMSF management.

The firm delivers six integrated service lines: Tax and Compliance, Business Structuring and Setup, Growth and Advisory, Succession and Personal Planning, Transaction and Due Diligence, and Integrated Support (which coordinates with external legal and financial specialists). Engagements are delivered as direct professional services mandates rather than as a packaged technology platform, with positioning centered on partner-led strategic advisory rather than commodity bookkeeping.

ESN Partners targets three SMB customer segments: founders and startups requiring structuring and setup support, established business owners needing growth and tax advisory, and investors and family groups focused on succession, intergenerational planning, and transaction support. Publicly referenced client work spans fashion apparel (Attaquer) and fashion education (Orana Fashion Business College). Revenue is generated through fee-based professional services engagements; no subscription, transactional, or platform revenue mechanics are indicated, and there are no disclosed funding rounds, M&A activity, or AI/technology capabilities.

Core offering

ESN Partners is a Sydney-based chartered accounting and business advisory firm that delivers strategic accounting services across the full lifecycle of a business — from startup structuring and tax compliance through growth advisory, succession planning, and transaction due diligence. Clients engage directly with senior advisors (partners and consultants) for ongoing, relationship-based advisory rather than transactional compliance work. The firm serves founders, business owners, investors, and family groups primarily in New South Wales, Australia.

Product overview

ESN Partners is a professional services firm offering a unified suite of accounting and business advisory services. The firm provides six interconnected service lines: Tax and Compliance (smart planning and accurate lodgements), Business Structuring and Setup (foundations for growth), Growth and Advisory (expansion and funding guidance), Succession and Personal Planning (intergenerational continuity), Transaction and Due Diligence (M&A support), and Integrated Support (cross-functional coordination). These services are delivered through a team-based model where clients work directly with senior advisors rather than a software product platform.
