Celsmar
Market data, fundamentals and portfolio in one terminal
Celsmar is a professional, multi-market financial terminal that runs in your browser. A single screen brings together institutional-grade market data, interactive valuation, portfolio management with risk metrics, and AI-assisted analysis. It is built so that any investor can study the markets with professional-grade tools, without the complexity or the cost of traditional platforms.
I built Celsmar because every morning looked the same: one tab for quotes,
another for filings, a spreadsheet for my portfolio, a fourth window for the
macro calendar. None of them agreed with each other, and the moment I looked at
a European company the history got thin. Plenty of years of fundamentals for a
US name, often five for a Spanish or German one.
The first version was just a chart and a quote box. It grew once I realised the
hard part wasn't the interface, it was the data: two sources reporting dividend
yield in different units, prices quoted in pence, a company changing its tax ID
between filings, quarterly numbers that don't add up to the annual ones. Most of
the work since then has gone into normalising that, and into being explicit
about where a number comes from and when it was measured.
Today Celsmar covers US and European equities, ETFs and crypto in one place:
charts, fundamentals going back to 2005 for European companies, screener,
portfolio with multi-currency lots, valuation, macro calendar and an analysis
assistant. Bilingual (ES/EN), light and dark themes, and it works on mobile.
It's live and I'm still shipping. Happy to answer anything, and if you spot a
number you think is wrong, tell me. That's the feedback I want most.
