Thanks

Thanks so much — really glad the categorization is helping cut through the noise.

Thanks! OpenInsider is absolutely the OG in this space. To answer your questions: Latency: We poll the SEC RSS feed continuously. The parsing logic (classifying the transaction types) takes a few seconds. So, while not 'HFT real-time' (microseconds), it is 'human real-time' (usually appearing on our site within seconds of the SEC publishing). Sufficient for manual analysis, but maybe not for algos front-running the market. Business Model: We plan to keep the web interface (including the granularity and filters) free for public research. We believe this level of data transparency should be the standard. Our plan for a future 'Pro' tier focuses on automation and convenience, such as: Real-time Email alerts for specific tickers/insiders. API access for developers. Bulk CSV exports for backtesting. The goal is to make the best research tool free, and charge for the infrastructure tools."

Hi HN, OP here. OpenInsider is great and inspired this, we just wanted to modernize the stack. We focused on parsing Form 4s with more granularity (distinguishing grants/options from open market buys) and building a faster, mobile-friendly UI. Would love to hear your feedback on the data accuracy!

Nice work — making multi-agent networks A2A-compatible in an open-source framework looks very promising.

Your website grew to several thousand UVs per month in just two months — that’s impressive!

I’ve been working on http://www.13radar.com for the past 4 months, and we launched about two weeks ago. The platform tracks hedge fund portfolios in real-time based on SEC 13F filings.

I’m responsible for product research, analysis, design, development, and promotion. Most of the workflow was powered by AI tools — more than 60% of the research, design, and coding involved AI assistance. Initially we used Bootstrap for responsive design, but later switched to a lighter TailwindCSS framework.

Right now traffic is very low (just a few dozen users per day), and I’m trying to figure out whether that’s a product issue or simply a lack of promotion. Honestly, it’s a bit discouraging, but I’m hoping to learn from feedback and iterate.

Curious if anyone here has experience growing early-stage products with niche financial data — how did you approach the balance between product refinement and marketing?
