Rantum.
Senior data science & ML that ships. We find the signal others miss, and turn it into product.
Rantum is an independent data science & machine-learning practice. We build the measurement layer companies run on: data platforms, metrics infrastructure, attribution, and predictive models. We specialize in the hard part, turning messy, fragmented, or adversarial data into models, APIs, and products that ship, validated properly rather than just prototyped. That includes deep on-chain expertise: we scaled core data infrastructure at 0x Labs, advised the Uniswap Grants Program, and shipped data work for teams like Art Blocks.
Founded by Andrew Maury. Available for fractional data/ML leadership and select project engagements.
Data & analytics work for teams at
Selected Work
The through-line across everything we build: finding signal in data others can't use, by entity resolution, attribution, detection, and prediction, then shipping it as a live model, API, or product.
ClearTrace ● Live
Neutral, third-party proof of where DEX volume really originates, surfacing hidden, untagged orderflow plus execution quality and MEV across four chains. Live API + dashboard.
Cross-frontend attribution built on deep trace-call data, leveraging our open-source contributions to Dune's Spellbook.
AddressIntel ● Live
Predictive real-estate intelligence that fuses fragmented municipal permit records with multimodal AI to score teardown probability and flippability. Running live as a deal-sourcing service on the San Francisco Peninsula.
DePIN QoS Oracle Prototype
A real-time anomaly-detection oracle that scores the reliability of decentralized GPU compute (Akash, Render, io.net) as a 0–100 Compute Health Score for autonomous AI agents.

The Data & Model Audit
A fixed-scope engagement against one named pipeline, model, or data system. Three weeks, ending in a written report: findings, risk flags, and an ROI-ranked roadmap. It's yours whether or not we work together after.

What we do
Fractional Head of Data / ML
Senior data leadership without the full-time hire: strategy, architecture, and hands-on builds.
Data products & intelligence APIs
Design and ship data products, enrichment/attribution APIs, and predictive intelligence layers, like ClearTrace and AddressIntel.
ML & predictive models
Build, validate, and deploy models with real rigor: point-in-time discipline and honest backtesting.
Data & model audits
Assess pipelines, models, and data quality. Technical due diligence you can act on. Fixed scope: $12,000, 3 weeks.
On-chain & crypto data specialty
Execution analysis, cross-frontend attribution, MEV/labeling, and on-chain analytics. Deep expertise for crypto and fintech teams.
Why Rantum
A rare skill
Turning messy, adversarial, or public data into shipped products, not just analysis decks.
We ship, not just advise
ClearTrace and AddressIntel are live, sophisticated builds. Defensible infrastructure others can't easily replicate.
Rigor
We validate before we ship: backtesting and point-in-time discipline, rare among data freelancers.
Pedigree
Scaled data infrastructure at 0x Labs, advised the Uniswap Grants Program, and shipped data work for Art Blocks, plus open-source contributions to Dune's Spellbook.
Book
The DeFi Data Quick-Start
Reading On-Chain Truth with Dune Analytics. A short, hands-on guide that runs from a first query to a dashboard you can defend. Every query in it works against live on-chain data.
