SingleSource Technologies develops software for investment teams and advisers working on mergers and acquisitions.
SingleSource Technologies presents SiSo software for investment teams and advisers working on mergers and acquisitions. Its current product pages describe M&A OS, a suite of customisable applications spanning the deal lifecycle, and SiSo Diligence, a legal due-diligence reporting and collaboration product. This is deal-workflow software rather than a consolidated wealth-accounting platform.
M&A OS covers pipeline and screening, diligence, execution, and post-closing integration and value creation. The vendor describes tailoring the system to a team’s deal playbook, including how it assesses opportunities, synthesises findings and tracks post-closing activity. A buyer should demonstrate its own approval steps, documents and reporting requirements during a pilot rather than assume every existing process is supported out of the box.
SiSo Diligence lets legal teams compile findings and recommendations, centralise workstreams and review information through interactive dashboards. Published outputs include traditional reports, online reporting and a hybrid format, with Word report functionality. The product also describes generating workflows from diligence findings, tracking financial-model inputs and building post-merger integration plans.
The company calls its centralised store of diligence findings and deal data Institutional Memory: the intended use is to retain information that can inform future transactions. Its AI-related product claims describe assistance with the process, not a substitute for responsible legal and investment judgment. Teams should establish source-review responsibilities, permissions, retention and confidentiality controls before using live transaction documents.
For family offices, the relevant potential use is supporting an internal direct-investment or acquisition team and its legal advisers. That is a use-case assessment, not evidence of a named family-office customer or a claim that the system provides portfolio accounting, custody or investment advice.
The website footer names SiSo Technologies LLC-FZ. A dated 2024 privacy policy identifies SISO Holdings Ltd as parent and controller and gives an Abu Dhabi postal address; that document alone does not establish the current contracting entity or headquarters for every product. It names Luke Kyleman as CTO and data-protection officer at that date, so his present role requires confirmation before treating him as a current leadership contact.
The M&A page offers a tailored proof of concept, and the diligence page advertises pilots on live deals. Request a demonstration or contact info@sisotechnologies.com to confirm product scope, implementation, integrations, support, security documentation and commercial terms. Prices, headcount and a founding year were not established from the reviewed sources. Certification logos alone are not an independent security-certification check.
