Solutions

Analytics platforms, built end to end.

We take on the full stack of a data product: sourcing and cleaning the data, modeling it, and shipping the experience that makes it useful. Sports is our proving ground. The methods apply anywhere data is fragmented and decisions are hard.

What we deliver

Four capabilities, one team.

Most engagements combine two or more of these. Each one is something we run in production on our own platforms.

Analytics platforms

Public or private products that turn a stream of raw records into rankings, dashboards, and pages people search for.

  • Product strategy and information architecture
  • Server-rendered, SEO-ready web applications in Next.js
  • Scalable PostgreSQL data models and APIs
  • Design systems and accessible, responsive interfaces

Data engineering & pipelines

Ingestion from fragmented sources, with the identity resolution and validation needed to make the result trustworthy.

  • Importers and integrations with tournament platforms and partner systems
  • Entity matching across seasons, organizations, and name changes
  • Idempotent, observable pipelines with audit trails
  • Data quality monitoring and contributor review workflows

Predictive modeling & ratings

Rating systems and probability models that are explainable to experts and useful to everyone else.

  • Elo-style and Bayesian rating engines tuned to your domain
  • Win-probability and outcome models with calibration
  • Public accuracy tracking and methodology documentation
  • Per-segment analytics such as division, age group, or region

AI integration

Large language models applied where they add leverage: extraction, matching, summarization, and content operations.

  • LLM-powered document and roster extraction
  • Agentic workflows for editorial and support operations
  • Evaluation harnesses so model output stays accountable
  • Cost-aware architecture across providers and models

How we engage

From first conversation to a running platform.

  1. 01

    Discover

    We map your data sources, users, and the decisions the product must support.

  2. 02

    Prototype

    A working slice on real data within weeks, so the model and the product can be judged early.

  3. 03

    Build

    Production engineering: pipelines, models, interfaces, and the observability to run them.

  4. 04

    Operate

    We can run the platform for you, or hand it over with documentation and training.

Technology

A stack chosen for speed, scale, and cost.

We standardize on a small set of proven tools so we can spend our effort on the data and the product, not the plumbing.

  • TypeScript
  • Next.js
  • React
  • PostgreSQL
  • Cloudflare
  • Serverless & edge compute
  • LLM APIs (Anthropic, OpenAI)
  • Python for modeling
