Why we exist
Stop renting the software that runs your business
Why rent bloated OEM software components? We'll sell you better software at a fraction of the price, and you'll own it. SAASaftermarket helps companies replace expensive, rigid, or underused OEM SaaS applications with tailored software built around your requirements.
Instead of renting platforms and modules your team only partially uses, we deliver practical alternatives that give you the functionality you need without unnecessary cost or complexity. Our focus: dramatically reduce your software spend, improve operational fit, and give your business more control over the tools it depends on.
See how it worksFitment guaranteed
Our OEM replacement software meets every requirement your current solution delivers.
...and we guarantee interoperability with the systems already surrounding it. No gaps, no surprises at cutover.
- Same functional coverage as your current license.
- Verified interoperability with adjacent systems.
- Delivery timed to your renewal date.

More control
Own the roadmap, data structure, and feature priorities that matter most to your business.
Less bloat

We partner with you
Let's talk about your problem or opportunity. We'll build something awesome and leave you with the source code.
We're nice
We're here to put you in control of your software, not lock you in and gouge you for every penny like some people we know.
Who we serve
Built for teams ready to own their software
SAASaftermarket is built for businesses that have outgrown generic software or don't want to keep paying for oversized enterprise platforms. We target midsize to large organizations with substantial SaaS spend and an IT organization ready to own the software that runs their business.
- Companies paying for unused SaaS features or seats.
- Teams frustrated by rigid OEM modules.
- Organizations embracing AI, looking for cost offsets to rising AI token spend.
- Leaders looking for a smarter long-term alternative to subscription sprawl.
Start small
You don't need to replace your entire stack at once
SAASaftermarket helps you start where the business case is strongest: one overpriced module, one broken workflow, or one high-value process that deserves a better tool.

Get off my yard!
SaaS companies and consultancies love talking about building moats. What no one's talking about: those moats are built around your business, keeping you dependent on them.
Clunky old SaaS platform: spruce it up!
Would you go to the dealer to upgrade a 1970 Gremlin? Don't extend your clunky SaaS platform with overpriced OEM add-ons either.
Make or buy…hmmm.
Same old question, way different answer. In the age of AI-generated applications, there's no good reason to keep renting software.
Fits like a glove…
How many SaaS customers are using a platform so bloated it doesn't really meet anyone's needs, let alone yours, simply and elegantly?
First enterprise software licenses, then SaaS, what's next?
Extortion is the crime of getting money from someone by using threats, force, or intimidation. Sound like your SaaS vendor? First there were enterprise software licenses and +20% annual maintenance fees (that go up every year, and you're really hosed if you try to discontinue them)…that wasn't enough, so now they rent you software that you never own at an even higher cost of ownership, they call it SaaS. What comes after SaaS? SAASaftermarket.com, your software, your way.
Get off your SaaS…
So your SaaS is slow and stubborn, you're probably not going to win the race with it. No worries, go to saasaftermarket.com and trade your SaaS in for a winner! We'll put old SaaS out to pasture where he belongs.

Our Process
A team of AI agents, one accountable delivery partner

- Delivery is coordinated with your existing SaaS license renewal date. You don't pay us until you decommission your existing license.
- Industry-leading IT professionals oversee every interaction and give final approval on the application. The agents do the heavy lifting, people are accountable for the outcome.

About
Vision & Mission
SAASaftermarket was founded to use AI to empower companies to design, build, deploy, and maintain bespoke enterprise-class software applications that they own.
In the age of AI there is no good reason to pay high annual SaaS fees to rent bloated, generic software applications. We developed a patent-pending process to do this one thing more effectively and efficiently than any other company.
We are fully committed to our customer relationships and specifically reject the SaaS industry's modus operandi: lock in customers and exploit that lock-in to the greatest extent possible. You will like our people, enjoy our process, and we will leave you better than we found you: with tighter, cleaner, bespoke software your users will love and you will own.

Dan Brennan
Dan has spent most of the last forty years helping IT buyers deal with a problematic IT industry. After ten years as a senior manager and executive at KPMG, Andersen Consulting, and Capgemini, he became disgruntled by the perpetually late, over-budget, poor-quality delivery of large IT projects.
So he co-founded Gladwyne Software Surety, bringing disciplined underwriting and project insurance to large IT projects. His next company, A-Frame, introduced construction management to IT, an expert third party assuming fiduciary responsibility for a full-lifecycle IT project on the client's behalf, common in construction, unheard of in IT. A-Frame managed dozens of the industry's largest IT projects, totaling over $1B in value, saving clients hundreds of millions.
Dan also has a track record leading information technology transformation programs including saving clients over $150M in annual IT spending. Now, with AI enabling the production of elegant, bespoke, enterprise-class applications in a handful of weeks, there is no longer any reason to pay hundreds of thousands of dollars per year to rent inflexible, bloated third party software. We built a company to help you fix that. It's time for your software, your way.

Every field recalculates your KPIs immediately, in the Live Dock to the right. No "run report" button required.
WACC or your required rate of return is a good default for discount rate. Inflation rate is captured for reference in your exported case.
CAPEX Items
CAPEX covers one-time upfront costs, like migration, setup, or licenses purchased outright, rather than ongoing subscription fees. These are depreciated over your analysis period.
