Joseph Johnson, Founder

I’ve held multiple finance and accounting roles across companies from seed stage to Series A and beyond. I've experienced all stages of company growth, including most recently serving as Controller and then Director of Finance at a company where I led the accounting/finance efforts for public filings, including S-4 and 10-Q filings. With my background in scaling finance operations, I’m passionate about helping SMBs streamline their financial workflows and prepare for growth.

Bailey Spell, Founder

Previously, I worked at Microsoft, where I was one of two selected by the Office CTO to integrate agents into Office while then becoming the first engineering hire at a seed-stage workflow automation startup. There, I helped the company grow from $0 to $120k in ARR. Now, I am helping lead a new era of finance and accounting for businesses starting with bookkeeping.

LedgerUp: Turn Your Contracts 📝 into Revenue💰
See original launch post ›

TLDR;

LedgerUp built an AI revenue teammate—Ari—to eliminate the multiple tools to juggle to get from “contract signed” to “cash in the bank.” Ari integrates with your CRM, automates invoicing, chases payments, and lives in Slack with real-time revenue data. The result? No more manual data entry, overdue payments, scattered data, and hiring FTEs to spend countless hours wasted in back-and-forth amongst different departments.

Below is an example of CRM → invoice process:

Why does this matter?

3 out of 4 businesses face payment delays, with the root cause beginning at the invoice creation stage.

The Pain: Most companies juggle contract softwares (ex: DocuSign/PDFs), spreadsheets, and a manual billing process riddled with errors, overdue payments, and hours spent data-entering.

Why It Matters: These inefficiencies lead to missed revenue, cash flow constraints, and wasted staff time. Founders often feel they need extra full-time staff just to manage invoicing.

How does Ari solve this?

Signature to Revenue, Automatically

Ari takes over the moment a contract is signed:

  1. Zero-Touch Contract Import: Signature lands → Contract processes → Revenue flows. All automatic, all instant.
  2. Intelligent Revenue Automation: Every signed agreement is automatically billed to its unique billing requirements
  3. Real-Time Slack Updates: Approve the final output in Slack and ask questions as needed

While others offer yet another tool to learn, your AI teammate takes over the moment a contract is signed.

Team/Origin Story

During his years as a finance director for startups, Joseph lived the revenue operations nightmare firsthand. His days were consumed with juggling dozens of different apps – one for contracts, another for invoicing, yet another for payment tracking, and endless spreadsheets to tie it all together.

The "solution" was always to hire more FTEs to manage the chaos, but that just shifted the burden of wrestling with broken processes to someone else.

Teaming up with his childhood friend Bailey, who had been building AI Agents for the past 2 years, they recognized this wasn't just their problem – it's a universal pain for any company with contracts that need to get paid.

They're on a mission to liberate founders and finance teams from revenue operations chaos, giving them back the time and clarity needed to focus on what matters most: growing their business.
