Bring labelled data and call an API. MathFi.ai refines your data, builds a production-grade model, validates it, and hosts and serves it, the same day. No ML infrastructure to run, no data-science team required, and every decision is deterministic: same data in, same answer out. It is at its best on the decisions that cost you most, the rare ones your current models miss.
Which claims are fraudulent. Which customers are about to leave. Which applicants will repay. Years of labelled history sit in your systems, and the patterns are in there.
It has meant specialists you cannot hire fast enough and a quarter of work per model: cleaning, feature engineering, tuning, validation, deployment, monitoring. Most organisations get a handful of models a year through that pipeline, if any.
The predictable fraud gets paid out. The savable customers leave. The good applicants get declined. Not because the signal is missing, but because the route from data to production has been too long to walk more than a few times a year. That is the bottleneck MathFi.ai removes.
MathFi.ai works on any decision that lives in labelled tabular data: risk, retention, operations, quality, safety. But the fastest payback is where the case you care about is rare and each miss is expensive. That is where standard models are weakest and MathFi.ai is strongest, so it is where most teams start.
Surface more fraudulent transactions, claims and applications for review, with fewer honest customers flagged along the way.
Identify the accounts likely to leave while there is still time to keep them, and aim retention spend where it changes the outcome.
Approve more of the customers who will repay and catch more of those who will not, instead of trading one error for the other.
Pay honest claims fast and route the small minority that deserve investigation.
Predict rare breakdowns from operational data before they become downtime.
Flag the rare, high-stakes cases that population-level screening misses.
The flow below is not a roadmap; it is a working day. You provide labelled data in the morning. Feature Refinery cleans it and selects the features that matter. Model Crucible builds the model and validates it on held-back data. MathFi.ai publishes and serves it. By the end of the day your application, or your agent, is calling a live endpoint and getting deterministic decisions back.
A day is possible because of what is underneath. MathFi.ai runs on Cellular Balanced Learning (CBL), a genuinely novel machine-learning architecture our co-founders invented after decades of building production models the slow way. CBL is not a wrapper around open-source libraries; it changes how the model is built. Rather than searching across more than a hundred settings for a good decision boundary, CBL constructs dynamic cell boundaries that adapt to the structure of your data as it trains, and the relationships between them are learned inside the architecture.
That is why a CBL model exposes two hyperparameters where a gradient-boosted model exposes more than a hundred. The tuning decisions a specialist normally makes by hand, learning rate, depth, sampling, regularisation and the rest, are internalised in how CBL is built. The expertise sits in the architecture, not the operator, which is what lets a team without deep ML staff get a strong model, and lets a team that has one skip the tuning marathon.
It also earns its keep on quality. Most business prediction problems suffer from class imbalance: the cases that matter are a small minority of the data, and conventionally trained models sacrifice them for overall accuracy. Because CBL handles imbalance structurally rather than through oversampling patches, the same-day model is also the one with the strongest minority-class recall and precision in our benchmark. And it is a service, not a software project: MathFi.ai hosts and serves the model, with every decision reproducible and auditable.
Read how CBL works in the docs →Most teams have tried at least one route to better predictions, and two things go wrong. The hard models, defeated by feature selection, more than a hundred hyperparameters and overfitting, often never reach production, so the value never lands. The ones that do ship are weakest exactly on the rare, costly cases. That gap, felt most by smaller teams frustrated at how little their current approach returns, is what MathFi.ai is built to close.
Doing this in-house means months of work per model and specialists who are hard to hire and harder to keep. Picking the right features, managing more than a hundred hyperparameters and fighting overfitting means many attempts never reach production at all, and the ones that do patch rare events rather than solve them, with oversampling tricks like SMOTE and class weights. MathFi.ai handles the rare cases structurally, in how the model itself is built.
The large AutoML platforms are expensive and complex to adopt, and at the end of the tuning run they hand you the same gradient-boosted models your team already runs, with the same blind spot on rare events. You pay platform prices for automation of the status quo.
The new generation of tabular foundation models is genuinely interesting, but it is not deterministic. If you cannot reproduce a decision, you cannot audit it, explain it to a regulator, or debug it when it goes wrong. MathFi.ai gives the same decision on the same data, every time.
LLMs are probabilistic by design. That is the right property for language and the wrong one for a decision that has to be trusted: a lending call, a fraud flag, a churn intervention that must be right and repeatable. Use an LLM to talk. Use MathFi.ai to decide.
MathFi.ai runs several competing algorithms and automatically selects the best-performing model for your data, so you are not betting on a single approach, and you are not hand-tuning your way to it.
Fewer missed cases and fewer false alarms at the same time; deterministic and auditable; no data-science team required; and it reaches production the same day.
Under class imbalance, headline accuracy hides failure, so we measure the minority class: the fraud, the default, the failure, the case you actually care about. Here is how MathFi.ai performs against the five libraries most teams already run, each on an identical train and test split.
| Decision | MathFi.ai · F1 % | Best other · F1 % |
|---|---|---|
| Credit approval | 88.50 | 86.21 |
| Consumer default risk | 63.60 | 59.70 |
| Signal integrity / anomaly detection | 97.44 | 91.89 |
| Cardiac risk detection | 84.20 | 82.63 |
| Stroke screening | 27.04 | 20.31 |
Highest minority-class F1 in 6 of 7 datasets, and the highest or joint-highest recall in all 7.
Of rare warranty fraud surfaced for review, against 82 to 84% for the gradient-boosting methods. Every point in that gap is fraud that would otherwise have been paid out.
Higher F1 than a fully tuned XGBoost on credit approval, with 4.24 points more precision at the same recall: fewer good customers wrongly declined.
MathFi.ai benchmark, July 2026. Seven public datasets. Identical train and test splits. Five standard libraries as baselines.
Where a method beats us on a secondary metric, our study says so plainly.
See the full benchmark study, all seven datasets →You know the answers are in your data. Fraud losses, churn, bad debt: you can see the cost lines, but building models has meant hiring a team you cannot find or afford. MathFi.ai gives you a production prediction capability without the department. Bring labelled data; get a served model.
You have the team, and a queue of rare-event problems that resist the standard toolkit. MathFi.ai clears that queue: same-day models with minority-class recall your current stack cannot reach, deterministic outputs your risk committee will accept, and your scientists freed for the work only they can do.
You operate where every decision may need to be explained, to a regulator, an auditor or a customer. Or you are building agents that act on predictions and cannot ship on a model that answers differently on the same input. MathFi.ai is deterministic end to end, so every decision is reproducible on demand.
MathFi.ai models are callable from your agents, copilots and applications through a documented REST API with an OpenAPI spec. Every prediction returns a deterministic, auditable decision your systems can log, replay and explain from the exact inputs the model saw. This is the difference between an agent you demo and an agent you deploy. Native MCP support is on the roadmap; today MathFi.ai is agent-usable through standard API integration.

LinkedInWe are choosing a small number of design partners. Bring a decision your current models get wrong too often, or a prediction you have never been able to build at all. We build a high-performance model on your own data and show you the lift against your own held-back validation data. This is for leaders who want to get past the tooling and straight to impact.
GenAI taught machines to talk. The next decade is teaching machines and agents to decide, and those decisions must be right, repeatable and auditable. MathFi.ai is the deterministic layer that GenAI calls when a decision must hold up: the prediction utility beneath the agentic enterprise.
