About ML Alpha
What Is ML Alpha
ML Alpha is an investment platform that runs machine learning models over US stock data and hands the results to ordinary investors. The idea comes from two friends, Mark Thebault and Carlos Hervas, who started it during the 2022 market slump. Mark wanted good stocks without grinding through company filings one by one, and machine learning on bulk financial data gave him a shortcut. The product they built takes that same shortcut public.
The platform leans on a simple premise borrowed from Jim Simons and his Medallion Fund: systematic, data-driven stock picking can beat the market, and the talent to build those systems lives far outside hedge funds. ML Alpha tries to open that door. You get AI scores, an AI screener and a portfolio marketplace in one subscription, and the community supplies the human layer on top.
The catch is scope. This is a research and decision tool for the US market, not a brokerage. It does not execute trades, and the AI scores are statistical signals, not guarantees. A free plan exists, but the deeper data access and unlimited backtesting sit behind the paid tiers.

Key features
AI Stock Screener
The Screener covers over 5,000 US publicly traded companies with more than 25 years of historical data. You filter on fundamental and technical factors, and each result carries a description, financial charts and statements. Machine learning predictions sit alongside the raw numbers, so a screen can mix classic value or momentum rules with the model's view.
AI Top Picks and ML Alpha Scores
AI Top Picks turns the platform's ML Alpha Scores into a shortlist tied to your stated investment goals. Instead of starting from a blank screener, you get a set of stocks the model rates highest for your objectives. The scores are the headline number here, and they come with verified past performance rather than a black-box claim.
AI Financial Expert
The AI Financial Expert is a generative AI helper that explains a company's financial state in plain language. You ask about a stock and it walks through the numbers, so you can check the health of a company without reading every line of a 10-K. It pairs with the screener, which means the analysis points back to the data you were already looking at.
Data Science Studio
The Data Science Studio lets advanced users build their own machine learning models through a point-and-click interface, with no coding required. You pick the data and the prediction target, then the platform handles the training. It ships with the curated ML-ready datasets ML Alpha uses for its own models, so you start from the same material.
Backtesting and Benchmarking
You can backtest any screening approach against historical data to see how it would have behaved. The platform compares a strategy's performance against the market benchmark, which answers the question most stock tools sidestep: did this rule actually beat the index, or just feel clever? The free plan includes 15 backtesting credits per month, and paid tiers raise that limit.
Portfolio Marketplace
The Marketplace is where the community layer lives. Investors and data scientists list portfolios, and subscribers pay to follow them live, with notifications whenever the owner changes a holding. Sellers set their own price, and the platform's example math lands at $10 per month per follower. A Portfolio Leaderboard ranks performance so you can see who is worth following.
Custom Meta Model
The meta model scores stocks on five criteria: short, mid and long-term performance, dividend growth, and volatility. You adjust how much weight each one carries, so a dividend hunter and a momentum trader can dial in very different models from the same engine. It is the part of the platform that rewards people who know what they want from the market.
Pros and cons
Pros
- Free plan is real, with up to 25 AI Top Picks, 15 backtesting credits a month and three portfolios, no credit card
- Curated ML-ready datasets let data scientists train and submit models without building a data pipeline first
- Marketplace lets anyone with a track record earn from their research, with a leaderboard to sort the results
- Backtesting against 25+ years of history answers whether a strategy beat the market, which most screeners skip
- One subscription covers screening, AI insights, model building and following, so there's no stack of separate tools
Cons
- Covers the US stock market only, so investors holding non-US shares get little value
- No brokerage link, you research here and place trades somewhere else
- The AI scores carry past-performance verification but no guarantee of future returns, and the site markets performance heavily
- API availability is not documented publicly, which leaves developers unsure how to pull data out
