Job Description & How to Apply Below

How we do it
Ascend automates the entire insurance financial lifecycle—from collections and accounting to reconciliations and disbursements—helping businesses streamline operations and increase profitability.
In the AI era, software costs are decreasing and AI makes technology more powerful and accessible. Businesses should maximize monetization by embedding technology into financial flows, rather than simply selling SaaS.
That’s why AI + fintech is our edge—seamlessly integrating financial automation into transactions to create real, lasting value. Customers don’t just buy software; they unlock powerful financial efficiencies with a 5-7x ROI.

Insurance is a $10T+ industry running on legacy systems. AI-powered automation embedded into payments and transactions will move the industry forward.
Ascend’s mission is to become the leading financial automation platform for insurance by 2030—powering the entire industry’s financial operations while transforming the way trillions of dollars move.
