The New Standard in IPOs

Addressing the costs, complexity and conflicts of interest in the traditional IPO book building process

Our Mission

We’re here to help grow the equity IPO market in the UK, across Europe and, ultimately, globally, by supporting the development of a fairer and more cost-efficient IPO book building process. SquareBook contributes in two ways: by improving the quality of the process which matches issuers to investors, and by helping reduce barriers to entry that affect both issuers and investors. Our core proposition is to better align the interests of issuers and successful share applicants through using innovative technology.

Our Launch

In 2015 we bought a software company serving firms working in the primary market, then developed our business model by working in step with the FCA’s own investigation into Corporate and Investment Banking and Occasional Paper 15. We successfully applied to be part of cohort 3 of the FCA’s Project Innovate and will have regulatory authorisation to conduct a live IPO. SquareBook’s launch coincides with the introduction of new COBS 11A rules; our platform manages and complies with the new IPO process.

Our Approach

We recognise that the underlying themes of recent regulatory initiatives in financial services - transparency, fair play, efficiency and improved competition - could and should be extended to the IPO book building process. We acknowledge the direction of travel by regulators, and also developed SquareBook’s innovative book building functionality to better align the interests of issuers and investors. We’re positioned to take advantage of opportunities to streamline and improve the efficiency of the equity IPO market.

Our Values

How we operate and what we do is driven not by our rules but by our culture, which embodies the highest standards of ethics and compliance. We believe this is the best way of building a sustainable business in the long term, and is the best foundation for SquareBook, our employees, our clients and our customers to succeed. SquareBook's founders, Mark and Joe, have already agreed to contribute 10% net profits to charitable causes.
