MantelinInternal tools
The spreadsheet became a system.
We build the dashboards, queues, and admin screens your team already improvised, so the work runs on a tool instead of a file and a set of rules 1 person remembers.
4 signs a spreadsheet is running the business.
Only 1 person knows the rules
The logic lives in someone's head and their copy of the file, and the work stops when they are out.
Everyone is working from a different copy
2 people edit at once, 1 version wins, and nobody can say which numbers are current.
The numbers are always a day behind
Someone exports, pastes, and reconciles before you can answer a question anyone should be able to ask.
Nothing stops a bad entry
A wrong value saves as easily as a right one, and it is found later by whoever it costs.
What we do about it
1 place instead of 6
The file, the shared inbox, and the side notes become 1 tool holding 1 current answer.
The rules move into the tool
What people are supposed to remember becomes what the screen will not let them get wrong.
Access and history by role
People change what their job needs, and every change carries who made it and when.
Reporting without the export
The dashboard reads the live data, so nobody rebuilds the same report every week.
How we work
Understand the real work
We learn how the work happens today and where it gets stuck. Then we map what matters.
Build the right solution
We build in short iterations. You see working software early and often.
Launch and keep improving
We launch it and stay on. As your work changes, the software changes with it.
Built by people who actually run this stuff.
We're engineers and former operators. We've run the systems we build, on-call included.
Senior-led
Every engagement is led by a senior engineer.
20+ years shipping software
Across startups and enterprises.
Security first
Least privilege, and backups you can actually restore.
Chattanooga-based
On site in Chattanooga, Tennessee, and remote for teams across the US.
