Hard problems,
working tools
Tythys turns quantitative reasoning, modeling, and scientific thinking into software you can actually use — focused tools, validated against real results, priced for the people who need them.
What Tythys is built on
— and tested against
Every product on this site exercises at least one of these. Every decision — what to build, what to ship, what to refuse — gets measured against them.
Quantitative Reasoning
Numbers that mean something
Turning vague questions into measurable ones. Units, scales, error bars, sanity checks — the discipline of reasoning with numbers instead of about them.
Modeling
Math that mirrors reality
Finding the equations and abstractions that capture how a system actually behaves — beam under load, portfolio under risk, signal under noise.
Scientific Thinking
Hypothesis · test · revise
Treating each tool as an experiment: state the assumption, validate against known results, fail loudly when wrong, ship only what holds up.
Problem-Solving + Software
From insight to interface
Compressing the loop from "I think this is the model" to "anyone can run it" — clean code, validated outputs, a UI that respects the user.
Focused tools for
real problems
Each tool below is one of the four pillars made tangible — quantitative reasoning, modeling, scientific thinking, or problem-solving compressed into something you can run, validate, and rely on.
Vertical SaaS
GatewaySight
API Gateway observability for reliable operations
Monitor gateway health, trace request flow, and detect latency or error spikes early so your team can resolve incidents faster.
Engineering Simulation
EngineerCalc
Beam deflection & structural calculators
Beam deflection, bending stress, support reactions, and safety factors for the four most common load cases. Validated against Roark's Formulas.
Engineering Simulation
PhysicsSim Pro
Structural & fluid simulation for engineers
Affordable web-based physics simulations for small firms — structural loads, fluid dynamics, thermal analysis. No $50K license required.
Quantitative Finance
PortfolioSigma
Monte Carlo portfolio & risk modeling
Options pricing, portfolio optimization, and Monte Carlo retirement simulations — scoped to what can be implemented correctly right now.
EdTech
MathCanvas
Interactive math & physics visualizations
Animated, manipulable explorations of calculus, linear algebra, and physics for universities, tutors, and self-learners.
ML / Analytics
AnomalyLens
Anomaly detection for manufacturing & IoT
ML anomaly detection for small manufacturers — no data science team required. Plug in sensor data, get actionable alerts.
Consulting
Custom Models
Bespoke computation & simulation work
Have a specific calculation or modelling problem? Open to scoped projects where the problem is well-defined and the expected output is clear.
The approach
Each tool follows the same discipline — understand the problem first, implement it correctly, then ship something clean.
Frame the Question
Translate a vague need into a measurable one. What are the inputs, the outputs, the units, the failure modes? Quantitative reasoning before code.
Build the Model
Find or derive the equations. Implement the core in Python — NumPy, SciPy, or plain arithmetic — and check it against textbook cases and known answers.
Test Like a Scientist
Hypothesise, perturb, compare. Edge cases, sanity checks, validation suites. If it disagrees with reality, the model is wrong — not reality.
Ship a Tool, Not a Notebook
Wrap the validated core in a clean interface so someone who needs an answer — not a programming environment — can actually use it.
Founder-led.
Methodically built.
Tythys builds specialized analytical tools grounded in quantitative modeling, scientific reasoning, and applied engineering. Each product is designed for correctness, clarity of interpretation, and practical use—not features built for a slide deck.
Work proceeds in small, verifiable steps: compare against established benchmarks, then ship when it earns its place in real workflows. Long term, the goal is dependable software between heavyweight enterprise platforms and fragile, spreadsheet-bound processes.
