The short answer
Astra 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.
