AI-native software & analytics · London
Infinity Square Labs builds software with AI agents that plan, write, test and review code every day, under human direction and sign-off. We put document intelligence and on-device processing into our own products, and we turn business data into decisions you can defend.
What we do
Agents build. Models understand. Analytics measure. Each feeds the next, which is the infinity in our name.
We run teams of AI agents that take a specification, write the code, write the tests, review each other's work and raise what they can't resolve. People set direction, review findings and approve every release.
Models that read real documents: finding the signature lines, dates and parties in a contract nobody formatted for a machine, extracting what matters, and running where the data already is, often entirely in the browser.
Data platforms, forecasts and dashboards built to answer a specific decision, with every metric defined and owned. We show the likely range of outcomes rather than a single confident guess.
How we build
Every working day our agents pick up the next batch from the plan, build it, test it end to end and hand it to a separate reviewing agent that tries to break it. Findings become tickets. Nothing reaches production without a person reading the result and approving the release.
Products
We run our own products, so every method we recommend is one we depend on. Most of them process your files on your device and never upload them.
Upload a contract and the fields are already placed: AiresDocs reads the document, finds every signature, date and name line and assigns it to the right person. Sign from any phone in 48 languages, with a tamper-evident certificate on every agreement.
Merge, split, compress, edit, OCR and sign PDFs in the browser. Nothing is uploaded.
pdfmagpie.comCompress, resize, crop and convert images, including iPhone HEIC, privately on your device.
pixwrench.comTake-home pay, mortgage, loan, VAT and savings calculators for the UK, US, Canada, Australia and Germany.
moneyotter.comA free crypto tax report from your exchange CSVs, calculated in your browser.
cryptotaxowl.comSnowball, avalanche, consolidation and payoff calculators, every figure engine-verified.
debtwren.comPrinciples
The useful question about an AI system is not whether it is impressive but whether you can trust what it did. We design for that question.
Models are measured on documents and data they have never seen, with precision and recall reported as numbers. When a result is illustrative we say so.
Where a job can run on your device, it does. Where it can't, we collect only what the product needs and encrypt what is sensitive.
Agents propose and build; people decide. Every release, every data model and every recommendation has a named human who stands behind it.
Strict content security policies, reviewed dependencies, signed audit trails and independent review before anything reaches a customer.
