Consulting & Custom Work
Optimatika brings deep expertise in mathematical optimisation and high-performance JVM computing to your project. We work with you directly — no layers of project managers or junior consultants.
Optimisation modelling
We help you formulate optimisation problems correctly, choose the right constraints, and select the solver that fits your requirements. Whether you're starting from scratch or need to improve an existing model, we can get you there faster.
Using ojAlgo's ExpressionsBasedModel, we design solver-agnostic models — the formulation is not tied to the engine that solves it, so moving to more solving power later never means rewriting the model. No vendor lock-in. We maintain integrations to most of the solvers worth considering, so the advice is not tied to one of them either.
Model review and performance work
Why a model is slow is usually not why people think it is. Investigation, profiling, reformulation and tuning — on models built with ojAlgo or on the systems around them.
Financial systems
Portfolio optimisation, risk management, Black–Litterman implementation, market simulation. We have years of experience building quantitative tools for financial services — ojAlgo was born from this work.
JVM performance
Numerical computing performance tuning, JVM selection, vectorisation, benchmarking. If you're doing heavy computation on the JVM and need it to go faster, we can help.
Fixed-scope engagements
Two sizes, priced before anything starts.
| What it is | Price | |
|---|---|---|
| One day | A single problem looked at properly — a model reviewed, a bottleneck found, an approach validated before you build on it | EUR 1 200 |
| One week | Enough time to change something — reformulate, integrate, benchmark, or build a working prototype | EUR 6 000 |
Prices exclude VAT.
These are timeboxes, not deliverable guarantees. You are buying a day, or a week, of undivided attention on your problem — not a promise that any particular outcome is reachable in that time. We will tell you before we start if we think the box is the wrong size.
Each one ends with something written: what we found, what we would do about it, and what we would not bother doing. That holds its value whether or not you engage us further.
They are arranged by enquiry rather than bought online, because a short conversation is what makes the box the right size.
Larger projects
Anything beyond a week is scoped and quoted individually. Longer full-time commitments are discounted — the day rate above is for short, self-contained work, where the cost is mostly in loading the context.
Everything is quoted before any work starts — you will not receive an invoice you did not agree to in advance.

Already have a subscription? Raise it on the channel you already have — an issue in ojAlgo-extensions reaches us directly, and we will scope it from there. Note that answering questions is included in your subscription; this page is for the work that is not.
