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 works

Fitment 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.

Why us

All we do is replace SaaS software

Our people, process and AI Agents make replacing your SaaS fast, secure and easy.

Lower costs

Low-cost AI-centered design and build process with no recurring cost.

Better fit

Build around your business instead of forcing your team into vendor-defined features.

More control

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

Less bloat

Replace oversized platforms with focused tools that are easier to train, use, and maintain.

Flexible modernization

Start with one module, one department, or one high-value workflow and expand over time.

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.

Perspective

SaaS: just say no!

Tired of paying annual tribute payments to SaaS robber barons? Don’t do it! In the age of AI there is no good reason to pay software rental fees for software we can deliver to you in a few weeks, and you’ll own it! Go to SAASAftermarket.com, tell us which SAAS fees your tired of paying for, and we’ll give you a price and delivery date for bespoke, enterprise-class, production-ready software your users will love. Not a generic, bloated software rental from a company committed to squeezing every penny they can out of you.

Perspective

Get off my yard!

If you’re a technology buyer, have you noticed the hot topic of conversation for SaaS companies and large consultancies is building moats? What no one is talking about is the moats they are trying to build are around your business! They’re trying to keep others out and keep you dependent on them. Your consultants and SaaS vendors don’t like you. Go to SAASAftermarket.com, tell us which SAAS fees your tired of paying for, and we’ll give you a price and delivery date for bespoke, enterprise-class, production-ready software your users will love, and you will own.

Perspective

Clunky old SaaS platform: spruce it up!

Are you going to go to the car dealer to upgrade your 1970 Gremlin? Of course not, OEM parts are way more expensive and way less cool. So don’t extend your clunky SaaS platform with OEM extensions. Go to SAASAftermarket.com, tell us which SAAS components you’re tired of paying for, or some salesperson is trying to sell you now, and we’ll give you a price and delivery date for bespoke, enterprise-class, production-ready software your users will love, and you will own. Not another generic, overpriced OEM add-on.

Perspective

Make or buy…hmmm.

Same old question, way different answer. Many SaaS applications are actually pretty hard to implement and maintain. It’s because they’re generic, bloated platforms that need to work for anyone and do lots of things you don’t need. In the age of AI, it’s often quicker and easier to build a bespoke application for you, and you own it, no more annual fees. Go to SAASAftermarket.com, tell us which SAAS applications you’re unhappy with and tired of paying for, and we’ll give you a price and delivery date for bespoke, enterprise-class, production-ready software your users will love, and you will own. Not another generic, bloated, overpriced rental.

Perspective

Fits like a glove…

How many of the SaaS companies’ customers are using your SaaS platform? Are all their businesses just like yours? Or…is your SaaS platform so bloated it doesn’t really meet anyone’s needs…certainly not simply, elegantly in a user-friendly manner. Go to SAASAftermarket.com, tell us which SAAS applications your users don’t like, and you’re tired of paying for, we’ll give you a price and delivery date for bespoke, enterprise-class, production-ready software your users will love, and you will own. Not another round peg in a square hole.

Perspective

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.

Perspective

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.

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.

Leadership

Dan Brennan

dan@saasaftermarket.com

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.
