Fazeshift

Fazeshift provides an AI-powered platform for automating the entire accounts receivable (AR) process for businesses, particularly targeting enterprises and high-growth startups. Founded in 2023 by Caitlin Leksana and Timmy Galvin, the San Francisco-based company aims to eliminate manual, time-consuming tasks associated with invoicing, payment processing, and collections.

The founders, who met while earning their MBAs at Harvard Business School, experienced the inefficiencies of AR firsthand in previous ventures. Caitlin Leksana, the CEO, previously led a crypto marketing automation startup and was a consultant at BCG, giving her insight into operational pain points. Timmy Galvin, the CTO, holds computer science degrees from MIT, served as a nuclear submarine officer, and worked at a fintech startup automating bank operations. Their combined experience led them to pivot from a different startup idea to create Fazeshift, addressing the fragmented data issues across platforms like Salesforce, QuickBooks, and Stripe.

The company's core product is an AI agent that uses large language models (LLMs) to manage the end-to-end AR workflow. It integrates with a client's existing software stack (CRM, ERP, etc.) to extract contract data, generate accurate invoices, automate payment reminders, and handle collections. Unlike traditional Robotic Process Automation (RPA) tools, Fazeshift is designed to handle complex and variable billing scenarios with greater precision and flexibility. This automation helps businesses reduce operational costs, save time, and improve cash flow by shortening the Days Sales Outstanding (DSO).

Fazeshift operates on a B2B, SaaS model. In January 2025, the company announced it had raised $4 million in a seed funding round led by Gradient, Google's early-stage AI fund, with participation from Y Combinator and others. The platform is built to be secure and compliant with standards like SOC 2 and PCI.
