What PEI does

PEI Group is a membership-focused business intelligence company headquartered in London that informs and connects investment professionals across global specialist financial markets. Founded in 2001 and operating with 501-1,000 employees across seven offices (London, Hong Kong, New York, Sydney, Tokyo, Los Angeles, Singapore), PEI serves asset managers, institutional investors, family offices, investment banks, law firms, consultancies and advisors, with a member base that includes Blackstone, Brookfield, Bain Capital, EQT, Ares Management, Oaktree, Kirkland & Ellis and EY. The company delivers market insight, data and journalism through a portfolio of specialist brands powered by a digital publishing, analytics and database platform, supplemented by professional networks and events that enable knowledge sharing, profile building and relationship development.

The company's core technology stack is a digital publishing, analytics and database platform supporting multiple specialist brands. In March 2026 PEI acquired Scientific Infra & Private Assets (SIPA), the leading global index, benchmark and rating provider for private infrastructure and private equity markets, which produces what the company describes as the only indices and benchmarks that genuinely reflect the risk and performance of private markets as an asset class. This was followed in May 2026 by the launch of a next-generation private infrastructure platform targeting advanced analytics and benchmarking for private markets decision making.

PEI operates a recurring subscription membership model, monetizing access to intelligence, data, analytics, professional networks and events for senior investment professionals. Revenue mechanics are enterprise-tier and pricing is not publicly disclosed. The company is privately held with no disclosed parent or institutional investor, and growth is being driven by M&A (SIPA), product expansion (the new infrastructure platform), and global footprint maintenance across EMEA, North America and APAC.

Direct peers

• With Intelligence (formerly Acuris): Closest direct comparable: a private, subscription-driven business intelligence and events business serving institutional investors, asset managers and the alternatives ecosystem, with overlapping product formats (data, events, networking) and buyer personas.
• PitchBook (Morningstar): Provider of private-market data, intelligence and research on PE/VC deals, funds and investors — overlaps directly with PEI's private-equity intelligence offering and competes for the same asset-manager and advisor budgets.
• Preqin (BlackRock): Global leader in alternative-assets data and analytics across private equity, private debt, real estate and infrastructure; directly competes with PEI/SIPA's benchmarking and fundraising-data products.
• Institutional Investor: Long-standing trade media, events and research brand serving institutional investors and asset managers; directly overlaps with PEI's journalism, awards and convening offerings.
• IJGlobal: Data and intelligence provider focused on infrastructure and project finance deals — closely aligned with PEI's Infrastructure Investor franchise and infrastructure benchmarking push.

Broad incumbents

• MSCI: Global index and analytics provider that has been expanding into private-asset benchmarks and risk analytics; overlaps with SIPA's index proposition and competes for institutional benchmarking budgets.
• S&P Global Market Intelligence: Large-scale financial data, research and analytics platform covering public and private markets; competes for enterprise intelligence spend at the same institutional buyer set as PEI.
• Bloomberg: Dominant terminal-based financial data, news and analytics provider extending into private-markets coverage; the principal incumbent competing for the same institutional member wallet.

Emerging players

• Mercer (alternative-investments research): Consultancy-led alternatives research and benchmarking practice serving institutional allocators; competes in private-markets benchmarking adjacent to SIPA's index proposition.

Others

• ION Group (DiligenceVault, Wall Street Systems): Financial data infrastructure and analytics provider serving capital-markets participants; an adjacent ecosystem enabler rather than a direct competitor, but increasingly relevant as private-markets data infrastructure consolidates.
