## What is SellB.io

SellB.io is an all-in-one platform for creating **interactive experiences that convert traffic into leads and sales**, without code.

It unifies in a single system:

- Link in Bio
- Smart forms (Typeform-style)
- Sales funnels with conditional logic
- Analytics and monetization

**Problem it solves**:
- Bio links **don't convert**
- Forms are **isolated**
- Funnels are **complex and expensive**
- Tools don't talk to each other

**SellB.io** eliminates friction and centralizes everything.

**Ideal Use Cases**:
- Content creators needing more than a simple bio link
- Small businesses selling products/services from social media
- Coaches, consultants, and influencers capturing leads
- Entrepreneurs wanting simple funnels without Clickfunnels complexity
- Personal brands seeking a professional presence with a short URL
- Instagram and LinkedIn professionals

2. Hero Screen with button "What are you interested in?"
3. Conditional Split Path:
   - If "Products" → Catalog screen + Buy button
   - If "Services" → Lead Form + Information
4. Thank You screen + CTA to social media

- **Ideal for**: Complex funnels with conditional logic
- **Navigation**: Dynamic routing based on user responses
- **Interface**: Canvas with drag & drop nodes, visual connections

**Advanced Features**:
