What accounting leaders are saying
Managing AI risk at scale is non-negotiable. Operator's explainability resonated immediately.

Before JackPod, we had to turn down work due to capacity issues, but now, if a prospect is a good fit, we know the JackPod team can handle anything we throw at them!

We're onboarding clients faster now because our accountants are not tied up with daily work, and profit per headcount has doubled in 2025 because of Jenesys

JackPod clients take half the time for year-end accounting compared to my internally managed clients.
The SameProblemsEvery Month.
Your Practice
Capacity is the constraint. Not opportunity.
- Month-end drags into week three
The rest of the work has to wait
- Senior staff doing junior work
Recovery rates dropping and margin is eroding
- New clients feel like risk, not a win
Who's going to take them on?
- The quiet dread of another leaver
Burnout is spreading through the team
Your Clients
They're flying blind. And they know it.
- "Huge orderβdo we need financing?"
But you're doing month-end for 8 clients
- Decisions made on gut feel
Because the numbers are six weeks old
- Month-end tells them what happened
It doesn't help them now
- They call you for answers
You can't give until the books are done
Two problems. Same cause. The work only happens once a month.
Imagine month end with
AP, queries and Bank Rec done?
A dedicated AI bookkeeper for every client. Transactions coded daily. Missing documents identified immediately. Queries resolved before they stack up.
One dedicated AI per clientβwith built-in human review by the Jenesys team as part of ongoing training. Your AI learns your practice, learns each client, and gets smarter with every resolution. Never unsupervised. Always improving.
The Proof Is In ThePractices
Join the firms already delivering faster, more accurate numbers to clients who notice.
Trust That's Already Proven
Top 50 practices don't gamble with client data. Neither should you.
SOC 2 Type II. GDPR. Cyber Essentials+. DPA. The same standards the industry's most rigorous practices already verified before signing.
Speed That Changes The Conversation
48-hour numbers mean you're the advisor, not the chaser.
Your SME clients are flying blind. When their cost and income numbers are less than 2 days behind live, you're not reporting history β you're shaping what happens next.
Accuracy That Compounds
By month three, Jack knows your clients better than your best junior.
Every transaction trains the model on YOUR clients, YOUR coding preferences, YOUR way of running things. The longer you use Jack, the more irreplaceable it becomes.
