slicksammy

We are working with fintechs who have high touch / risky applications. The goal of our software is streamline this process for them while also making it a much better experience for the customer.

For now the focus is on forms. Forms can include a static/predefined section, an ai-generated section or both. 

Forms
- static_form_part (json)
- ai_generated_form_part (json)
- ai_generated_sections (json)
- final_form (json)
- intake_q_id (uuid)
