The guy who noticed the bill you forgot about
Every month, somewhere between a gym membership you haven't used since January and a streaming service you signed up for during a free trial three years ago, your bank account quietly hemorrhages money. You know it. Your bank knows it. And for a long time, nobody did anything about it.
Jordan Mackler decided that was a problem worth leaving MIT for.
In January 2022, while enrolled in MIT Sloan's MBA program, Mackler took a leave of absence to build ScribeUp full-time. He had co-founded the company the year before, in January 2021, alongside CTO Yohei Oka. The thesis was sharp: subscription bills are the largest category of uncontrolled consumer spending, and banks - the institutions trusted with the most sensitive financial data on the planet - are doing almost nothing about it.
The consumer version launched in 2022 and hit #1 on Product Hunt the day it went live. That was a signal. But Mackler had noticed something more interesting than the consumer demand signal: the institutions that stood to benefit most weren't the customers. They were the banks and credit unions sitting on the transaction data.
ScribeUp pivoted to B2B, and the real game began.
Today, ScribeUp is an embedded, AI-powered recurring bill management tool that financial institutions can deploy natively inside their banking apps. Members get visibility and control. Banks get a retention and engagement lever they never had before. The typical integration takes 30 to 45 days. By June 2025, ScribeUp had gone so deep into the credit union ecosystem that it formed its own CUSO - a Credit Union Service Organization - signaling it wasn't just building for credit unions, but had become structurally part of them.
In August 2023, Mucker Capital led a $3 million seed round, with Red Cedar Ventures and MIT Sandbox joining alongside. The money went toward accelerating a partnership pipeline that now includes Service Credit Union, Advia Credit Union, Chartway Credit Union, Orsa Credit Union, and NorthCountry Federal Credit Union - each one a bet that subscription management is the next frontier in digital banking differentiation.
When Service Credit Union rolled ScribeUp out to its full member base in January 2025, more than 7,000 members enrolled in the first weeks. Members weren't just using it. They were going out of their way to call member services to say thank you.
That's the kind of product feedback that changes a founder's conviction.
