A New Way to IPO

Our multi-sided digital platform provides the first simplified, transparent and cost-effective way to help growing companies raise capital on regulated stock exchanges

What We Offer

A listing on a regulated exchange offers a growing company access to capital, a liquid market in its shares, and serves as an attestation of its management and their vision. But unlike the innovative and forward-thinking companies that use an IPO to raise capital, the IPO process itself remains rooted in outmoded and inefficient business practices that reflect a bygone era. Built up piecemeal over the years it has become an overly elaborate fandango in which the interests of the end users of the market, issuers and investors, are often compromised by the conflicts of interest that afflict their advisors.

Not surprisingly many companies have been attracted to alternative ways of raising new capital that appear less complex, expensive and opaque. But too often these other options result in a situation where the interests of founder and investor are misaligned.

SquareBook changes all this. We provide a modern platform that demystifies the IPO process by giving back control to the company issuing its shares. Advisors still have their part to play, but our platform’s unique approach to using modern technology to connect issuers and investors means that decisions about investor selection, pricing, and share allocations are free from the conflicts of interest that compromise the existing process. And our policy of engaging retail as well as institutional investors means we have access to a wider pool of capital and deliver a better outcome.

Our platform has been designed specifically to meet the needs of growing companies. With SquareBook companies get an IPO process that suits their individual needs, find investors whose interests align with their own, all in a simpler, cost effective and efficient way.

Who We're For

SquareBook connects issuers with all participants in the IPO process. Our platform expands the capital pool by opening primary markets to a wider audience. This streamlined approach reduces friction, ensures regulatory compliance, and improves outcomes and efficiencies for all participants.

Growing Firms

We provide an expanded capital pool by including high quality private and smaller institutional investor participation. Firms and founders get better visibility and early interaction with investors through our innovative ecosystem, with real-time transaction insights to investor interest and feedback.

Our approach, which fundamentally aligns the interests of the issuer with those of the investors, will deliver better pricing, shareholder engagement, and a more stable shareholder base.

Retail Investors

Previously only available to large institutional investors, the retail investor now has the same access to information, investment opportunities and pricing in IPO transactions where issuers welcome retail participation.

SquareBook’s suite of products facilitate a media-rich information flow between investors and issuers.

Private investors can filter IPO opportunities based on their needs-based profiles.

Institutional Investors

SquareBook provides a single source of access to IPO opportunities in a fair, efficient and regulation-compliant environment. We remove barriers to entry, enabling all institutional investors – large or small – to participate in primary market IPOs.

The platform integrates with existing IT workflows (via the industry standard FIX protocol), helping investors to meet compliance requirements such as pre-trade approval, and reducing error rates.

Allocations are based on issuer requirements rather than advisor relationships, and all investors receive equal access to issuer communications and broadcasts via our platform.


Advisors and syndicates benefit from improved efficiencies and regulatory compliance as outdated manual processes are replaced with the SquareBook rules-based technology. Real-time insight into the book-building process improves efficiency. The allocation process also helps to demonstrate impartiality and justify final decisions.

The platform also enables sponsors to ensure all analysts engaged in a transaction - connected and independent - have equal access to all relevant information.

Advisors benefit from increased deal flow as SquareBook makes it easier and cheaper for firms to go public.
