This document describes a lightweight CRM called Volta that is designed for phone-centric businesses. It addresses common problems such as not knowing which customers to call, when to call them, or having call history across departments. Volta provides APIs to trigger phone calls to be added to call queues for different departments like billing, sales, and support. It can integrate with phone systems through a single line of JavaScript and provides caller ID, call history, and a per-minute pricing model starting at $99/month. The founding team previously worked at companies like YC, Microsoft, and Berkeley and is seeking $500K in funding to expand engineering, business development, and grow Volta.
