Products that do what I built a tool to visualize the Peter Thiel stock portfolio (13F data) does
I've always found raw SEC filings painful to parse, so I built a site to make institutional holding data more accessible and visual. I recently updated the data to analyze the peter thiel stock portfolio (tracking Founders Fund and associated vehicles) for Q3 2025. It's interesting to see the divergence from standard tech indices—heavy on defense/hard tech and very little consumer SaaS. You can see the visualization here: https://www.13radar.com/guru/peter-thiel Would love any feedback on the UI or suggestions on other metrics I should calculate from the 13F data.

Hi HN, We’re a small team working on 13Radar.com, which we launched about two weeks ago after 4 months of development. I’m the founder, and together with the team we’re building a platform that tracks hedge fund portfolios in real-time based on SEC Form 13F filings. AI has been a major helper in our workflow. For a single webpage, we often consult multiple AI systems in parallel, generating different versions and comparing them side by side before deciding on the final design or implementation. More than 60% of the research, design, and coding involved AI assistance. For UI design we used…

Congressional trading data is relatively commoditized, but I couldn't find any open-source version with the features I wanted. The data is lagged (median 28 days from trade to disclosure, and 19% miss this deadline), but there's still interesting patterns to explore. Repo: https://github.com/kadoa-org/congress-trading-monitor Let me know if you have any suggestions for improvements!

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 a web page that aggregates data about data center buildup, sovereign fund investments into AI and bottlenecks. The objective is to predict AI race cooldown by looking at a potential decrease of activity involving these elements. The website looks at the quarterly forms from the 5 biggest hyperscalers and adds their CapEx into the mix, calculating a composite index in the end showing how likely it is for the AI race to slow down. Enjoy!

Hi HN, I've been working on 13radar.com, a site focused on tracking institutional holdings. Today, I’m releasing a beta version of our new Insider Trading Tracker. Like many of you, I've used OpenInsider for years. It's a legendary tool, but the UI hasn't changed in decades, and the data classification can be broad. I wanted to build something that feels modern and digs deeper into the data. How it differs from existing tools (OpenInsider / GuruFocus): Granularity: We parse SEC Form 4 filings to categorize transactions into finer types. Instead of just "Buy/Sell," we try to…
