Our take

Without the right software, sales teams run the risk of spending unnecessary time hunting for documents, updating CRM spreadsheets and editing invoices; all time that could be spent developing customer relationships and closing deals. SOPHIE is a digital assistant that takes the administrative pressure off sales teams.

As a virtual office assistant, SOPHIE automates repetitive tasks such as CRM document workflows and can integrate into Salesforce and HubSpot platforms. Its invoice management tool cross-checks invoices against purchase orders, ensuring accuracy at pace.

A small company, SOPHIE will be up against large competitors, but its laser-sharp focus on sales teams will no doubt help it win over clients.

Company values

Usefulness - We create tools that truly solve problems. Every feature we build, every decision we make, is guided by one question: Does this make our customers’ lives easier or better?
Curiosity - We ask questions, explore ideas, and challenge assumptions. Curiosity fuels our innovation. It’s how we discover smarter ways to work and uncover insights others miss.
Motivation - We’re driven to make an impact. Whether it’s a small improvement or a bold leap forward, we bring energy and purpose to everything we do.
Discipline - Great ideas mean nothing without execution. We take pride in focused, consistent work — from planning to performance, we stay sharp and follow through.
Accountability - We own our outcomes. When we commit, we deliver — to our customers, our teammates, and ourselves. If something goes wrong, we fix it. If it goes right, we build on it.
