Factor.fyi – use SQL to visualize financial, crypto and econ datasets

Hey HN, I'm Steve, co-founder of Factor.fyi, a new data platform for querying and visualizing financial datasets using SQL. During the pandemic, I took much more of an active role in managing my portfolio. I wanted to be able to make informed decisions about the investments I was making, and explore financial data in new ways. Market and Econ data are some of the most talked-about and widely-available datasets out there, but I was frustrated by the lack of options to answer questions I had, like, "What would have happened if I had started dollar-cost averaging VTI back in 2013?"[1] Or, "How…

What it does

In the maker’s words, at launch

Hey HN, I'm Steve, co-founder of Factor.fyi, a new data platform for querying and visualizing financial datasets using SQL. During the pandemic, I took much more of an active role in managing my portfolio. I wanted to be able to make informed decisions about the investments I was making, and explore financial data in new ways. Market and Econ data are some of the most talked-about and widely-available datasets out there, but I was frustrated by the lack of options to answer questions I had, like, "What would have happened if I had started dollar-cost averaging VTI back in 2013?"[1] Or, "How many days did BTC and ETH move in the same direction as the S&P500?"[2]. We built Factor to answer these questions. You can use Factor to query disparate datasets in ways that are impossible on any other platform. We currently have 20 datasets [3] that you can use to answer questions you have about the markets and create beautiful visualizations around them. Factor is community-powered and free forever; you can browse our community-built charts here [4]. We'd love to get feedback from the HN community, hear your thoughts on what datasets we can add, and get advice on how we can make the querying experience even easier for those new to SQL.

    FactIQ – a realtime econ+finance database for AI agentsJul 2026 · github.com · ▲7

    Hey HN, we built an Econ+Finance database to let AI agents do investment research. We spend a lot of tokens to organize macro releases and SEC filings into a clean format, so that your agents have more context to do actual analysis. The problem AI agents are great at data analysis. But they become ineffective if most of their context window is spent on gathering and cleaning data, instead of validating hypotheses. Data in the wild is messy and rarely standardized. Definitions and measurements change over time. This problem is compounded by a fragmented data universe. Point solutions exist…

    I built an open-source financial research terminal (SEC data and SQL)Jun 2026 · terminal.tesseractanalytics.ai · ▲5

    I posted this a few weeks ago and the server died under the traffic. Fixed that by adding an in-mem caching layer with Redis/valkey and added CloudFront caching for static content. Also upgraded the server. Also fixed the Firefox bugs, trying again. It's a research tool for US stocks. Financials for ~10k companies pulled from SEC filings. You can chart any metric across companies, filter news by ticker, ask questions in plain English and get a chart back. There's also SQL console against the whole database, which is the part I like to use together with the AI chat (generates an SQL…

    I built an AI that knows my net worth: 3 countries, 6 currenciesJul 2026 · demo.joinbrisa.com · ▲6

    I'm Canadian, live abroad, and my money is scattered across two countries, multiple currencies, banks, brokerages, real estate, and some private equity. No app could hold all of it, and none could answer a simple question like "what's my actual USD exposure?" Brisa pulls everything together (Plaid + manual accounts + real estate + PE, all multi-currency) and puts an AI on top that has my full financial picture in context. Instead of clicking through charts, I can just ask. Would appreciate any feedback!

    DataHub, open source datasets for Artificial Intelligence2017 · ▲14

    Hi HN! I am an undergrad student trying to build interesting things with AI. Recently, I was looking for a dataset I could use for a new project. I realized that it is really frustrating to go through all the government websites (with terrible UX) just to find some usable dataset. I set out to build a GitHub for datasets, named DataHub. Right now, we have more than 1000 datasets from Montréal and New York City, with more cities coming soon (and possible government agencies). All of this is wrapped into a powerful search. It's a breeze to find a dataset to work on. I'd be interested to know…

    A financial analysis and research tool powered by agents2024 · github.com · ▲6

    Hey HN! I've always been fascinated by financial markets. This month, I decided to build a tool to help with the research of stocks and cryptocurrencies. I'm using YFinance as a data source because it's free and provides a wide range of reliable market data. For sentiment analysis, I'm leveraging Google Trends to gauge public interest and sentiment over time. The tool, named Zenith, is a command-line utility with four main features: Market Analysis: Provides insights like moving averages, RSI, and volatility for selected stocks or cryptocurrencies. Sentiment Analysis: Uses Google Trends to…

    I built a tool to talk to Stripe data2024 · dataraccoon.io · ▲7

    Hey HN! I am a developer working on a startup doing lots of payment integration stuff with payment providers like Stripe. I built a tool to talk to Stripe data, just so that I can answer questions from our team. I turned that into analytics tool (sort of) to answer questions about MRR, churn, revenue etc. (https://www.dataraccoon.io/). There is a two minute demo video on the page if you want to see how it works, or you can use free trial without needing a credit card. I was wondering if you would use such a tool directly in Slack or prefer receiving messages about your metrics…

    Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
