You'd think this needs an engineer for 6 weeks — Tycoon Agent ships a polished free tool on Vercel in 21 days that ranks and converts.
The short answer
Tycoon Agent ships a free tool for lead gen in 21 days following the proven HubSpot/Calculator playbook. Week 1: she identifies 5 candidate tool concepts by mining Ahrefs for high-volume 'calculator', 'checker', 'generator', 'analyzer' keywords in your space, scoring each by search volume × commercial intent × build effort. You pick one. She writes the spec, designs the UX in chat, and scopes the MVP. Week 2: she ships v1 on Vercel as a Next.js page (no auth required, email gate optional after first use), wires up basic analytics in PostHog, adds proper SEO metadata, schema.org markup, and an OG image. Week 3: launches via 4 channels — your blog, LinkedIn, ProductHunt, and 3 niche Reddit communities. Submits to relevant directories. Sets up rank tracking in Ahrefs. Weekly Lark report shows traffic, signups, and SQL conversion. Realistic outcome: 500-2K visits/mo by month 3, 4-8% email capture rate, 50-150 leads/mo.

- Design and spec the MVP
After you pick: she designs the UX in chat (input fields, output format, share-result feature), writes the spec, and decides email gate strategy (optional after first use beats hard-gated for SEO).

What it looks like in chat
YouI want to ship a free tool to drive leads. I don't know what to build.
Tycoon AgentI just ran Ahrefs for your category. Top 5 candidates: 1. **AI API Cost Calculator** — 8.4K monthly searches, low competition, high commercial intent (people comparing providers). Build: 2 days. ETA traffic month 3: 1.2K. **Recommended.** 2. **LLM Token Counter** — 14K searches, but mostly informational, lower SQL %. Build: 1 day. 3. **Prompt Optimizer Tool** — 3.2K searches, high differentiation, but build is 5 days. 4. **AI Model Latency Checker** — 1.8K searches, niche but very high intent. 5. **API Key Audit Tool** — 900 searches, security-conscious buyers, premium leads. **My pick: #1.** Best volume × intent × effort ratio. By month 3 you should see ~1.2K visits/mo at 6% email capture = 70 leads/mo, ~30% MQL → 21 SQLs/mo at minimum. **21-day plan:** spec by Friday, v1 live next Wednesday, launch sequence the following Monday. Want to go with #1, or do another one resonate more?
