StackCut: the SaaS savings AI makes possible, from your QuickBooks export
How often each product is chosen within a category, 0–100% relative to the other.

As answered by people managing Wren and StackCut.net.
StackCut.net's answer:
StackCut turns a QuickBooks export into a sourced, CFO-ready business case for cutting software spend. Instead of generic benchmarks, it analyzes your actual vendors, flags the specific tools AI can now replace, and quantifies three-year savings with transparent, adjustable assumptions you can defend. It's honest by default — if the savings are negative, it shows that too. Free preview, then a $49 full report. No spreadsheets, no sales call.
StackCut.net's answer:
Tools like Zylo, Vendr, Torii, and Sastrify are built for enterprises with procurement teams and annual contracts. StackCut is built for operations and finance leaders at SMBs who need a defensible number fast — no implementation, no sales call. Paste your QuickBooks export and get a sourced PDF in about ten minutes, with a free preview before you pay. The edge is honesty: every figure traces to a benchmark, assumptions are adjustable, and negative savings are shown rather than hidden.
StackCut.net's answer:
Operations and finance leaders at small and mid-sized businesses evaluating their SaaS spend. They typically arrive with a QuickBooks export and need a savings business case they can present to their CEO. They're time-constrained and skeptical of inflated projections, so they want sourced, defensible numbers rather than hype — exactly what StackCut is built to produce.
StackCut.net's answer:
StackCut was built by Shawn Yeager, who spent three decades making technology sell: browsers at Microsoft, infrastructure at Accenture, Bitcoin payments at NYDIG, and an IoT hardware startup he ran as CEO. $300M in revenue across three decades and over 100 companies advised.
After selling software, buying it, and building companies on it, one thing stood out. What a company pays for its tools and what those tools actually cost are never the same number. The subscription is the line item. The real cost is the labor: triaging tickets, manual data entry, and errors from processes nobody tracks.
When AI started replacing entire SaaS categories, that gap became an opportunity. But nobody had a tool that could take a company's actual expense data and show the real number, with sourced benchmarks instead of made-up projections. So he built one.
StackCut.net's answer:
StackCut is a web app built with Next.js and React in TypeScript, styled with Tailwind CSS, backed by Neon Postgres, and deployed on Vercel. Vendor matching and spend analysis run client-side in your browser, and the report is generated as a downloadable PDF. Your expense data is never stored on our servers.

You can probably go to fiverr and have someone build you a website - just send them wren.co and ask how expensive it would be to create something similar. Source: over 3 years ago
If you really have it made, like you're upper middle class, you can easily afford to sequester the amount of carbon you emit yearly for not much money. My dog and I emit approx 18tons of carbon a year, which is like 3.5 times the world... Source: over 3 years ago
You could offset part of your past emissions on wren.co. Source: almost 4 years ago
