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 studio, with 6+ years in crypto. We scaled core data infrastructure at 0x Labs, advised the Uniswap Grants Program, and have shipped data work for teams like Art Blocks — and 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.
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 — and 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. Live B2B API.
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 — that'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
Data science at 0x Labs, Uniswap, and Art Blocks, plus open-source contributions to Dune's Spellbook.
Have hard data to make useful?
We're taking on select engagements — fractional data/ML leadership, data products, and models built and validated properly. Let's build something that ships.
