Our products

Tools we dreamed into existence

Two focused products. Both open-source. Neither designed by committee.

Live · Open Source
winkNLP
Developer-friendly Natural Language Processing.

A high-performance NLP pipeline — tokenization, sentence boundary detection, negation handling, sentiment analysis, POS tagging, NER, and custom entities — in a single zero-dependency package with full TypeScript support. Runs identically in Node.js and browsers.

winkComposer
Composable Streaming Intelligence.

From IIoT streams to actionable insight — in real time. Composable blocks for signal conditioning, statistics, anomaly detection, and flow control — from Kalman filters to spiking neural networks. Express what you want, not how to build it. AI-native via MCP Server. Purpose-built for SMBs and MSMEs. Runs identically from edge to cloud.

Why we exist

Powerful tools
belong in the open

Rigorous decision science has long been locked behind enterprise contracts, academic paywalls, and consulting retainers. We are changing that — one carefully crafted open-source package at a time.

Open source as mission

Every Graype package is open because rigorous tools should be freely available to anyone willing to use them well. No paywall. No enterprise tier.

First principles, always

We do not reach for a library when an algorithm will do. We do not add a dependency when a proof will do. Precision over convenience, every time.

Thinking in decades

No exit strategy. No VC timeline. We are building tools we intend to maintain and improve for as long as they remain useful — which is to say, for a very long time.

How we sustain the work

Niche consulting.
Serious clients.

Open-source work requires economic oxygen. Ours comes from selective, high-depth consulting engagements with organisations that need genuine quantitative expertise — not headcount.

The arrangement is honest: consulting revenue funds our OSS work. Our OSS work is the proof of capability that earns the consulting engagements. A flywheel we have been spinning for over a decade.

We work with a small number of clients at any time. We say no often. We stay long enough to do the work properly.

The studio

2¼ people who mean it

Small by design. No plans to become a consultancy, a startup, or anything other than a tightly run studio that ships quality work.
