What Mason Wilhelm does
Mason Wilhelm is a privately held executive search and leadership advisory firm headquartered in Sydney, Australia, with physical offices also in Melbourne and partner locations in London and Atlanta. Founded in 2019 by senior practitioners from leading global search and consulting firms (including Bain & Company, Russell Reynolds Associates, Derwent, Johnson Partners, and TritonExec), the firm serves boards, CEOs, and investors at enterprise clients across Australia, the United Kingdom, and the United States. Its practice is structured around four mandates: Executive Search, Board Search & Assessment, CEO Succession, and Leadership Assessment & Development, with sector depth across financial services, consumer and retail, industrial and healthcare, defence, aviation, and private equity.
The firm's central differentiator is Saigan, a proprietary intelligence platform built, owned, and refined in-house since 2024. Saigan combines a single data lake, 40+ specialised AI agents, and integrations with CapIQ, IBISWorld, and BoardEx to produce 48-hour market mapping turnaround, 50+ function, industry, and behavioural metrics per candidate, predictive stability and flight-risk scoring, and live client portals with transparent evidence trails. The firm publicly reports a greater than 98% 24-month placement retention rate, 15 days from brief to qualified longlist, and multi-dimensional digital-twin modelling of executive markets. Public artefacts include the Retail Executive Intelligence Dashboard, an interactive HTML capability overview (Mason Wilhelm × 1805), and a 13-page prospectus.
Mason Wilhelm generates revenue through retained, bespoke professional-services engagements on executive search, board, succession, and leadership assessment mandates, with each engagement led end-to-end by a named Partner and no publicly disclosed pricing. The go-to-market motion is partner-led enterprise field sales with no gatekeepers, supported by thought leadership on LinkedIn and downloadable capability artefacts on the firm website. Geographic distribution across Sydney, Melbourne, London, and Atlanta provides deliberate Asia-Pacific, UK, and US time-zone coverage for cross-border mandates.
