What STJ Advisors does

STJ Advisors is an independent equity capital markets (ECM) advisory firm headquartered in London with an Asian headquarters in Tokyo, founded in its current form in 2008 by John St. John, Simon North and David Jennison, and authorised and regulated by the UK Financial Conduct Authority. The firm advises corporate issuers, financial sponsors (private equity), governments and entrepreneurs on a per-transaction basis across IPOs, follow-on offerings, rights issues, block trades, capital increases, equity-linked instruments, SPACs/de-SPACs, private placements, and overarching strategic/exit advisory. STJ positions itself as deliberately unconflicted — independent of integrated investment banks and their product silos — and complementary to bank-led syndicates and M&A advisors, with the core differentiator being investor-side perspective derived from former top-ranked equity research analysts and portfolio managers.

The firm's underlying technology stack is centred on two proprietary assets: the "Atlas" database, which tracks bank and investor activity across global capital markets transactions, and an Investor Mapping Technology that identifies institutional investors across geographies. These underpin a suite of process innovations the firm has pioneered, including Rights Auction, IPO Auction, Early Look meetings, Investor Mapping, and a Strategic Research Advisory service designed to bring buy-side perspectives into pre-transaction positioning and valuation work. The Atlas database, Investor Mapping and Strategic Research Advisory are the explicit data assets that STJ claims give it a structural insight advantage versus pure-banking or M&A-only advisory competitors.

Commercially, STJ operates a professional services, fee-based model with advisory mandates typically negotiated on a transaction-by-transaction basis. Go-to-market is sales-led, relying on senior-professional relationships, repeat engagement from marquee PE sponsors (3i, Advent, Apollo, Bain, Blackstone, KKR, Cinven, Permira, Carlyle, General Atlantic, Hellman & Friedman, Warburg Pincus) and large corporates (Bankia, France Telecom, Solvay, iZettle, Ziggo, NN Group, TDC, Cellnex). The firm claims 1,500+ mandated assignments, €600bn+ in aggregate funds raised, and 30+ jurisdictions covered, with regional partners heading UK/Nordic/France/Benelux, CEEMEA, Spain/Portugal, DACH, Italy and Japan, and a combined deal-execution, strategic-advisory and senior-advisor headcount in the 11-50 range.

Direct peers

• Cenkos Securities: UK-focused corporate finance and stockbroking firm with a small-cap ECM franchise. Closely comparable on mandate type and issuer-segment profile.
• Peel Hunt: London-listed mid-market broker-advisor with a sizable ECM/Advisory franchise. Overlaps directly with STJ on UK and European IPO and follow-on mandates for mid-cap issuers and PE exits.
• Panmure Gordon & Co: UK-headquartered independent broker-advisor with a strong ECM franchise across mid- and small-cap. Highly comparable in business model (independent, advisory-led, UK-anchored) and explicit focus on equity capital markets intermediation.
• Numis (acquired by Deutsche Bank): Was until 2023 the closest pure-play UK ECM competitor to STJ, advising UK and European corporates on IPOs and follow-ons. Now part of Deutsche Bank's investment-bank franchise but historically a direct independent peer.
• Liberum Capital: UK specialist broker focused on equity research, sales, trading and ECM advisory. Comparable boutique scale and a similar client base of mid-market issuers and sponsors.

Broad incumbents

• Lazard: Global independent advisory and asset-management firm with strong ECM and capital-raise capabilities. Adjacent independent model with materially broader footprint and product mix.
• Rothschild & Co: Independent global advisory house with deep ECM and M&A capabilities. Competes with STJ on IPO and rights-issue advisory mandates for European large-cap issuers and governments, but at much greater scale and scope.
• PJT Partners: Independent advisory firm with active ECM and capital-markets advisory practice serving corporates and sponsors. Comparable independent model though with a US-heavy footprint and broader services.
• Evercore: Independent investment-banking advisory firm with global ECM capabilities including IPO advisory and capital markets. Comparable conflict-free positioning though dominated by M&A and US activity.

Emerging players

• Centerview Partners: Independent US M&A and capital-advisory boutique founded by ex-Morgan Stanley bankers. Comparable unconflicted model, increasingly relevant as a peer for STJ's larger global mandates.
