Why I Built It
I was tired of spending 30 minutes writing each cold email for B2B outreach. Most templates felt generic, and personalization took forever. So I built a tool that:
- Takes a company name, prospect role, and your offer
- Generates a personalized cold email with AI
- Matches the tone to the prospect (formal, casual, direct)
Lessons Learned
1. Ship fast, improve later
My MVP had literally one feature: generate a cold email. No login, no dashboard, no analytics. Just input → output. That was enough to validate the idea.
2. Free tier is essential for B2B tools
Nobody signs up for a paid tool they've never tried. The free tier lets people experience the value before committing.
3. $9/month is the sweet spot for new SaaS
After researching pricing for similar tools, $9/month felt right. Low enough to be a no-brainer, high enough to be sustainable.
4. Distribution > Product
Building the product took one day. Getting people to find it? That's the real challenge. SEO, social media, and community engagement are where the real work begins.
5. Reddit will ban your self-promotion
Learned this the hard way. Value-first content in communities like r/sales and r/Entrepreneur works much better than direct promotion.
