Database for analyzing US companies, visualize using Apache SuperSet
My main motivation was that I wanted to be able to drill down and filter across all the available stocks, look at the data for myself, and narrow down on the stocks I am interested based on my own sets of criteria, and make data-driven analysis for my personal investment strategies. I used PostgreSQL as the backend database for ELT data pipelines, and used Citus Data cstore_fdw for columnar compression for the final dataset. All financial data is coming from SEC Edgar, https://www.sec.gov/developer. I used Python for downloading most of the data. I also run the data load…
Database for analyzing US companies, visualize using Apache SuperSet launched on April 18, 2023 with 113 votes, #414 of 4,853 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
This tool provides a database of US company financial data sourced from SEC Edgar filings, allowing investors to filter and analyze stocks based on custom criteria. Built on PostgreSQL with columnar compression for performance, it uses Python for data processing and Apache Superset for visualization and exploration. The system is designed for individual investors who want to conduct self-directed, data-driven analysis to inform their investment decisions.

From the sources
Open Terminal by Tesseract Analytics brings professional financial research to individual investors — real SEC data, live market news, AI-powered analysis, and stock charts.
Detailed company research — earnings, margins, what filings actually say — has long been locked behind expensive professional tools. Not because the data was scarce, but because the tools to make sense of it were. Open Terminal changes that. It combines real SEC Edgar financial data , live market news, company summaries, and an AI you can ask direct questions — no finance background required. Better information leads to better decisions. That's the idea. Company data, news, charts, and AI — without switching between five different tools. Six tools, each built around a question a real investor would actually ask. Pull up revenue, operating income, R&D spend, or any other SEC financial metric…from tesseractanalytics.ai

(* within a few minutes of SEC filing) Currently does it for 1000+ US companies and specifically earnings related filings. By US companies, I mean the ones that are obliged to file SEC filings. This was the result of almost a year long effort and hundreds of prototypes :) It currently auto-publishes for 1000 ish US companies by market cap, relies on 8-K filing as a trigger. e.g. https://www.signalbloom.ai/news/NVDA will take you to NVDA earnings Would be grateful to get some feedback. Especially if you follow a company, check its reports out. Thank you! Some examples:…
Investorsexchange.jl – parse trade-level stock market data in Julia2022 · github.com · ▲136Backstory: I wanted to play with intraday stock data but couldn't find a free dataset anywhere. IEXCloud [1] offers API access to 1-minute granularity intraday historical price data, but I was worried that it could get expensive or unwieldy to build up a substantial dataset via API calls. Plus, IEX gives out their raw data for free. I probably should have just used the IEXTools python library [2] to parse IEX's raw data dumps, but I was working on a Julia project, so it felt more thematically appropriate to build a new tool from scratch. I haven't been actively using InvestorsExchange.jl a…
- IBI built an AI tool to analyze SEC filings the minute they're released2024 · docdelta.ca · ▲62
Hello everyone, I built this tool on Next/Node to automatically analyze new filings from the SEC and probe the Edgar API for new filings 24/7. We use AI to analyze the filings the second they are released. Free accounts to look at real filings (automatically updated) are available to any who sign up. If you have any questions feel free to ask.

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

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
