Mesodian

What it is

Mesodian is a web app for people who have not invested before. It puts short lessons, a scored view of each company, ready-made portfolios and a broker-linked tracker in one place, and it bills in euros. There are more than 50 learning modules with quizzes and a glossary. Each company gets five scores out of 100, built from what the site calls "88+ metrics": Quality, Growth, Value, Sentiment and Risk. On Risk a higher number means lower risk. Around them sit a screener, comparisons, a news and alerts feed, and insider, 13F and congressional-trade data.

Two features take it beyond research. More than 80 "ready-made ideas" are model portfolios labelled "Curated by Mesodian AI", with names such as AI Infrastructure, Internet Momentum and Political Trades & Gov Contracts, each carrying an "AI Score" the page defines as conviction strength. On Premium, a portfolio or rule can be connected to your own broker and rebalanced automatically.

The publisher is Mesodian, a business name on the Irish Companies Registration Office's register, number 794867, with a Galway address. The register's public mirror counted it as one month in business on 4 November 2026. The Terms were last updated on 15 September 2026, and the home page's "Featured on" strip names launch directories such as Product Hunt and SaaSHub.

Pricing

Three plans, all monthly, all in euros, checked on 4 November 2026. Free costs nothing and needs no card: every lesson, the overall score on every company, three full five-score breakdowns a month and one watchlist. Research at EUR 9.99 opens the full scores, the screener, comparisons, insider and institutional activity, political trading and sentiment. Premium at EUR 14.99 adds broker connections, live portfolio monitoring, a risk centre, "50+ automated trading strategies", automated trade execution, smart alerts, forecasts and a scenario engine.

No annual price is published. The Terms allow annual billing and promotional "founding-user" pricing, and say cancelling stops renewal without refunding the current period, apart from statutory consumer rights.

Data & coverage

The site names no market list and no data vendor. Every example on its pages is US-listed: NVDA, PLTR and Astera Labs, and SPY, GLD, TLT and QQQ on the ETF side. The insider, 13F and congressional data are US filings by nature, and the app's own note on institutional flow says the 13F data "is up to 45 days old". Logos load from Financial Modeling Prep's image host, which shows where the pictures come from and nothing about the prices.

The site states no quote latency either. The Terms say third-party information "may be delayed, incomplete or inaccurate", and the latency on this card reads delayed on that basis, not because a delay was measured.

Integrations

Broker connections run through SnapTrade, which the Terms and the privacy policy both name. The home page lists 27, from US brokers such as Schwab, Fidelity, Robinhood and Interactive Brokers to Trading 212, DEGIRO, AJ Bell, Wealthsimple and India's Upstox, plus the crypto exchanges Binance, Coinbase and Kraken. Whether a given broker allows trading or only reads holdings is SnapTrade's and the broker's matter, not Mesodian's. There is no API, the public pages document no export, and the site links no mobile app.

Limitations

• The model portfolios come with one-month returns and a conviction score on the home page. "AI Infrastructure +24.8% 1M, 94 Score" is the first thing the Discover panel shows, and the page does not say whether the figures are live or illustrative. The Terms say a portfolio's presentation is not a personal recommendation. A one-month return on an AI-picked basket is still the number a beginner will read first.
• Automated execution means orders without a click each time. The Terms say transactions "may occur without you manually approving each individual transaction", that disabling an Automated Portfolio may not cancel orders already sent, and that rebalancing can create taxable events. The pages name no regulatory authorisation for the service.
• Congressional trades are framed as foresight. The app's own glossary says lawmakers "see policy early, so their buying and selling can hint at what is coming". A House report is due the earlier of 30 days from notification or 45 days from the trade, so the hint arrives late.
• The score is not explained. The site names the five scores and the count of inputs, but not which metrics feed each score or how they are weighted.
• The publisher is new and thinly identified. A business-name registration does not say who owns it, the site names no founder or team, and the Terms' address has no town.
• Web only and priced in euros. The site links no iOS or Android app and shows no USD or GBP price.

Alternatives

Stockopedia is the established version of a ranked score on every stock, with its methodology published and UK coverage, at several times the price. Quiver Quantitative is where congressional and lobbying data is the product rather than one tab. A reader who wants a tracker with no trading attached is better served by getquin or the open-source Ghostfolio, and Composer is the place to look if automated, rule-based trading is the actual goal.
