One data stream. Infinite opportunities.

The Hacker News Plain Domain Tracker gives you something no paid tool offers: real-time detection of new product launches as they hit HN. Before Twitter. Before Product Hunt. Before anyone else.

Here's every business you could build with this.

---

1. Startup Discovery Newsletter

The Model: Daily or weekly email with the freshest startups from HN.

Revenue Potential: $500–$5,000/month via sponsorships

---

2. Investor Lead Generation

The Model: Sell lists of newly launched startups to angel investors and VCs.

Revenue Potential: $1,000–$10,000/month

---

3. Competitive Intelligence Service

The Model: Alert companies when competitors launch new products or rebrand domains.

---

4. Domain Aftermarket Alerts

The Model: Notify domain investors when similar or related domains launch on HN.

5. Startup Database / Directory

The Model: Build a searchable database of every startup that ever launched via HN.

Why It Works: Researchers, journalists, and marketers need historical data. Charge for API access or premium searches.

Revenue Potential: $100–$500/month per seat

---

7. Tech Journalist Tip Service

The Model: Feed breaking startup launches to tech journalists and bloggers.

Why It Works: Journalists need scoops. Being first to cover a trending HN launch drives traffic.

Revenue Potential: Retainer or per-tip pricing

---

8. Product Hunt Timing Intelligence

The Model: Track which HN launches later appear on Product Hunt and how they perform.

12. Acquisition Target Finder

The Model: Help serial acquirers find early-stage products before they raise funding.
