What ISEG Limited does

ISEG Limited (International Stock Exchange Group) is a London-based private fintech founded in 2016 that invests in and builds platform-based software applications to create efficiencies in capital markets. The company operates the Startup Stock Exchange (SSX) - a regulated marketplace running on the Dutch Caribbean Securities Exchange (DCSX) - where startups and small businesses sell ownership shares directly to qualified global investors. Its proprietary trading platform, rebuilt to be compliant with Central Bank Rules and Regulations, handles deposits, in-platform KYC, and securities trading for SSX-listed issuers, supported by strategic partners ESE Group (SSX operator), Allied SX (global trading infrastructure), and DCSX itself. IS EG reports thousands of registered brokerage clients and floats approximately four IPOs per quarter, while distributing local trading-platform presence across 50+ countries spanning Africa, Asia, Europe, Australia, the Americas, and South America.

The Capital Superhighway is ISEG's umbrella brand bundling investor reporting, news announcements, stock digitization, shareholder register management, and ongoing listed-company promotion, designed to take companies from early-stage funding through to blue chip. Surrounding the core exchange, the portfolio includes Director Check (an AI engine indexing 1.9 million directors for tenure, results, and personal-stock-sale verification), Fraud@ (phishing-email protection), BeShizzle (website-compliance checking), MobileNDA (digitized NDAs), MaximumOne (a single-page business-plan feeder to SSX), IPO Bidder (institution-to-company matching), Mobile IPO, the INC incubation platform, the Program for Equity, the TPEC multi-currency Private Equity Card, CRB corporate-registry tools, and the I Learn I Agree terms-and-conditions platform.

ISEG generates revenue across multiple streams: transaction fees on its proprietary trading platform, recurring brokerage subscriptions, professional services for listing preparation, and transaction-based income from IPO allocations. Distribution is direct-sales-led through the trading platform and SSX listings, with digital content marketing (iseg.co and Vimeo videos) and direct inquiry funnels for listing agents, advisors, investors, and listed companies. The hybrid customer segmentation treats early-stage companies and qualified global investors as primary segments, with listed companies as a secondary segment served by ongoing investor-relations and shareholder-management tooling.

Direct peers

• Republic: Republic is a multi-asset private-investment platform offering startup equity, crypto, and secondary-market trading access to retail and accredited investors. Its retail-investor focus, regulated broker-dealer, and secondary-market functionality closely mirror ISEG's brokerage + SSX model.
• Aquis Exchange: Aquis Exchange is an EU-regulated multilateral trading facility and exchange challenger targeting smaller-cap and growth listings. Comparable to ISEG as an emerging, technology-led exchange seeking to compete with incumbents by servicing issuers underserved by large venues.
• WeFunder: WeFunder is a leading US Regulation Crowdfunding platform offering retail investors regulated access to startup equity. It mirrors ISEG's targeting of early-stage, retail-investor inclusion in private capital markets via a regulated platform.
• Crowdcube: Crowdcube operates a regulated equity-crowdfunding platform that lets startups and growth companies raise capital from retail and qualified investors, with a secondary market for trading holdings. Like ISEG, it combines issuer services, investor onboarding, and regulated secondary trading on a single platform serving early-stage companies.
• EquityZen: EquityZen provides a private-securities marketplace that connects shareholders of late-stage private companies with accredited investors seeking liquidity. Comparable to ISEG in facilitating regulated secondary trading of pre-IPO and early-stage equity, though EquityZen is more US-focused and pre-IPO-skewed.
• Seedrs (now Republic Europe): Seedrs is a regulated investment platform enabling private companies to raise equity from retail and professional investors, with a secondary market for share trading. It is a direct UK-headquartered analogue to ISEG's SSX listing and brokerage model for early-stage issuers.
• StartEngine: StartEngine is a US equity-crowdfunding and private-investment platform with a regulated secondary market for trading shares of crowdfunded companies. Comparable to ISEG's model of combining issuer fundraising with brokerage and secondary trading access.
• SharesPost (now part of Forge): Forge (formerly SharesPost) operates a regulated secondary-market platform for private-company shares, serving accredited investors and issuing companies. It is comparable to ISEG's brokerage and SSX secondary-trading functionality for companies before they reach public markets.
• tZERO: tZERO is a regulated blockchain-securities alternative trading system that tokenizes and trades private-company equity. It mirrors ISEG's combination of broker-dealer, exchange, and digitisation capabilities for early-stage and pre-IPO securities, with a stronger crypto-asset angle.

Broad incumbents

• London Stock Exchange Group (AIM): LSEG operates the London Stock Exchange including AIM, the leading global market for small and growth companies, plus related brokerage and trading infrastructure. It represents the established incumbent in the niche ISEG targets with SSX — competing for the same growth-company listings, though at materially larger scale.
