Built by finance professionals, for finance professionals
Hackabacus is on a mission to eliminate the tedious, repetitive work that consumes the best hours of analysts, associates, and directors at the world's top firms. We build financial modeling tools and PowerPoint automation for finance teams that let you focus on what actually matters: the analysis.
Our Mission
Reclaiming lost hours for the finance industry
Every day, thousands of analysts and associates at private equity firms, investment banks, and infrastructure funds spend hours on repetitive formatting tasks. Aligning decimals. Standardizing fonts. Reformatting pitch decks. Adjusting number formats across hundreds of cells. It's work that has to be done — but it shouldn't take this long.
Hackabacus was founded to solve that problem. Our Excel plugin for private equity and investment banking teams automates the formatting workflows that eat into your day, giving you back the time to focus on financial modeling, deal analysis, and the strategic thinking that drives real value.
The Problem We Solve
Finance teams deserve better tools
Studies consistently show that PE analysts, investment bankers, and finance professionals spend 30% or more of their working hours on formatting and presentation tasks rather than substantive analysis. That's hundreds of hours per year per person spent on Excel formatting, PowerPoint slide standardization, and model cleanup instead of valuation analysis and deal execution.
The existing tools on the market were built in a different era. They're slow, bloated, and designed without genuine input from the people who use them daily. Hackabacus is the modern Macabacus alternative — purpose-built as a lightweight, high-performance Excel plugin for private equity and investment banking workflows. We work directly with deal teams at leading firms to understand their actual needs, then build focused tools that address real pain points.
Whether you're formatting a three-statement model, standardizing a 200-page CIM, or preparing a management presentation deck under a tight deadline, Hackabacus gives you the speed and precision to deliver institutional-quality work in a fraction of the time.
Our Team
Built by people who understand the workflow
Hackabacus was founded in 2025 by people who spent years inside deal rooms, building models at 2 AM, and formatting pitch books under impossible deadlines. We know the pain because we lived it.
Our team combines deep finance domain expertise with world-class software engineering. We understand that an Excel plugin for private equity needs to handle XIRR formatting differently than a consumer spreadsheet tool. We know that investment banking teams need PowerPoint automation for finance deliverables that respects their firm's brand guidelines. These details matter, and they inform every product decision we make.
We didn't study the finance workflow from the outside. We lived it — and we built the financial modeling tools we always wished we had.
