Now onboarding partner firms

We build the tools that take process work off the desk.

Arbitrex builds software for investment banks and private equity firms: bespoke systems, automation of the manual work around them, and AI applied where it genuinely earns its place. The tools on this site are two we built ourselves, and the clearest examples of how we work.

What we do

Software for the work around the deal

Deal teams are not short of data. They are short of process: the connective work between having information and being able to act on it. That is the part we build for.

Bespoke software builds

Internal tools and workflow systems built for one firm, around the way that firm actually works.

Workflow automation

Removing the manual steps around your existing systems rather than replacing them.

AI and agent implementation

Language models put to work where they genuinely help, and kept out of where they do not.

Tools we have built

Two worked examples, not one product

Alongside client work we build our own tools, each aimed at a specific question a deal team actually asks. They are the clearest answer to what we mean by software built around the process rather than around the data, and they are examples of the approach, not the whole of what we do.

For private equity origination teams

Private Equity Origination Engine

Screens the register on your mandate criteria, scores what matches, and tells you when something changes.

“Which companies fit our mandate, and what moved this week?”

Works from: The companies register and filed accounts
Gives you: A live, scored shortlist that keeps itself current

See the demo

For M&A advisers and corporate development

Strategic Fit Engine

Derives a buyer's acquisition logic from its own deal history, then scores the universe against it.

“Who should buy this company, or what should this buyer acquire?”

Works from: A named counterparty, a sector and a geography
Gives you: A ranked, scored and sourced target or acquirer list

Who we are

We have sat on both sides of the process

We have worked in private equity and investment banking. The inefficiencies we build against are ones we sat through, which is why we start by asking where your week actually goes.
