Building Applied AI systems for complex markets
We develop machine learning infrastructure and predictive systems that transform decision-making in data-rich, high-stakes environments.
Intelligence at scale
RationalSphere builds applied machine learning systems for industries where decisions are complex, data is abundant, and stakes are high.
Our approach combines rigorous statistical methodology with production-grade engineering—translating research into systems that operate reliably at scale. We focus on domains where predictive accuracy creates measurable value and where traditional approaches fall short.
We don't chase trends. We solve hard problems.
What we're building
We're developing a portfolio of AI-powered products across verticals where machine learning can fundamentally improve decision quality.
Investment intelligence for residential real estate. Machine learning meets property analysis.
Visit CasaBuddy.aiAlternative data signals for retail investors. Sentiment analysis, flow detection, and earnings surprise prediction.
Retail and restaurant site selection intelligence. Foot traffic prediction, demographic fit, and competition analysis.
Compound-target binding prediction for drug discovery. Models affinity, selectivity, and ADMET properties before synthesis.
Multi-drug regimen optimization. Predicts synergies, antagonisms, and toxicity profiles for combination therapies.
Who we are
Our team brings together passionate data scientists, machine learning researchers, and engineers who thrive on solving problems others avoid.
We combine deep technical expertise with practical product sense—building systems that are not just theoretically sound but genuinely useful. Our backgrounds span quantitative research, distributed systems, and product development at scale.
We value rigor, intellectual honesty, and shipping things that work.
