Treehouse Software – 40 Years and Still Moving Forward (Part 2)

by Joseph Brady, Director of Business Development and Cloud Alliance Leader at Treehouse Software, Inc. 



Many readers know that Treehouse Software has been around since 1983, serving enterprises worldwide with industry-leading software products and outstanding technical support. This blog series will dig a little deeper into Treehouse Software’s origins and explore how founder and president, George Szakach blazed a trail from being a programmer and manager in the 1960s and 1970s, to creating and growing his own software company from the early 1980s up to the present.

Treehouse First Generations… 1980s – 90s

As mentioned in Part 1 of this series, George’s foundational mainframe experience from 1960 to 1975, combined with skills honed from 1975 to 1982 at Software AG, planted the seeds for the next step, building Treehouse Software. George explains:

“Treehouse Software was started during Christmas of 1982, with a consulting assignment I decided to take in the Kingdom of Saudi Arabia doing ADABAS performance analysis and tuning.  In addition, I was asked to teach the customer how to use ADAMINT (which I get credit for developing from July 1975 through May 1979 – or blame, take your pick).  I thoroughly enjoyed my 10 weeks in the Kingdom, where I became a big fan of pistachio nuts. 

Treehouse Software was incorporated in mid-1984 in Sewickley, PA.  The plan then was to provide consulting and educational services to SAG sites, while developing software products related to the SAG enterprise.  The services might sell the products, and vice versa.  It worked and still works.  I started hiring help almost immediately as the demand for products and services was growing.

By the way, Sewickley is a small town near Pittsburgh where the oil, steel, coal barons of the 1800s and early 1900s had their summer homes up the hill from the river.  The 100-year-old horse-and-wagon trails and stone walls around the estates can still be seen.”


The Sewickley Bridge spans the Ohio River between Sewickley and Moon Township, PA.

Some interesting facts about Treehouse Software, Inc.

By the end of the 20th century, Treehouse designed, developed, and released ten products, most notably:

Treehouse also marketed several additional products from companies around the world.  Most were related to ADABAS.

Other miscellaneous Treehouse happenings last century:

  • Taught classes for over 4000 students, ADABAS and Natural related, and related to Treehouse products. 
  • Partnered with 20 affiliates or marketing representatives in various countries, topping out at 14 around 1990.
  • Produced 55 issues of the popular Treetips newsletter, with a hard-copy circulation of 13,000 per issue.
  • Attended 11 Software AG conferences.
  • Presented at 90 regional and local Software AG meetings in various countries.
  • Visited affiliates, customers, and partners in at least 24 countries on all continents except Antarctica.
  • Invited to Oracle Conference in 1995, in Philadelphia, where Emilie Szakach entertained the crowd with an on-stage dance with Chubby Checker.
  • Bought four IBM mainframes for the company.
  • Hired many top notch programmers and analysts, tech writers, support personnel.
  • Along with most of the world, we awaited and prepared for the feared Y2K debacle, which didn’t happen. However, as the year 2000 approached, one of Treehouse’s most popular and most requested give-aways ever, was our Y2K desk clock…


Cha, Cha, Cha, Changes…

Along with many new products, innovations, and memorable, contributing staff moving through the doors of the Treehouse, we’ve also had several iterations of the company logo and colors, as seen in the following graphic. Do you have a favorite?

Government and Infrastructure Customers are Looking to Modernize Their Crucial Mainframe Data on Highly Available, Scalable, and Secure Cloud Databases

by Joseph Brady, Director of Business Development / Cloud Alliance Leader at Treehouse Software, Inc.


Everyone has seen the recent headlines about how aging and outdated technology nearly crippled the airline industry. As a result, modernizing and securing information systems has taken center stage and top priority again. Even before the airline IT disaster, the COVID-19 crisis was a critical event that forced modernization to become a strategic imperative for government, supply chain, healthcare, utilities/energy, financial, and defense industries. All of these sectors have critical data residing on a variety of long-standing mainframe databases (often still updated by COBOL applications), including Db2, VSAM, IMS/DB, Adabas, IDMS, Datacom, and sequential files. Unlocking the value of this important data can be difficult, because the data is often utilized by numerous interlinked and dependent programs that have been in place for decades.

“The Federal Aviation Administration’s 30-year-old hazard-notification system recently had its first crash ever to cause a nationwide grounding of flights. The incident is focusing a bright light on the outdated federal computer systems that, IT experts say, are increasingly vulnerable to failure and cyberattack.” – Source: Christian Science Monitor Daily

As a result of this renewed push to modernize IT systems, Treehouse Software has been seeing a significant increase in requests from Cloud platform partners, government agencies, and other infrastructure customers to evaluate modernization solutions that replicate data, in real time, on highly available and secure Cloud-based databases, data warehouses, etc.. Fortunately, Treehouse has the deep mainframe expertise and software tools to help. 

Since 1983, Treehouse Software has been working with many of these enterprises with mainframes in the areas of data migration, security, control, auditing, performance enhancement, etc.. Treehouse has also expanded its capabilities to focus on new requirements for modernizing legacy mainframe databases on various Cloud and open systems platforms with the tcVISION mainframe data replication product.  tcVISION is the primary tool  in Treehouse Software’s “data-first” approach, whereby immediate data replication to the Cloud helps customers get on the fast track to meeting spikes in demand for vital information, especially in times of crisis.

Some examples of popular Cloud databases supported by tcVISION are Amazon RDS PostgreSQL, Google Cloud SQL for SQL Server, and Azure SQL-Database. A complete list of data sources and targets that are supported by tcVISION can be found here.

Replicating mainframe data on the Cloud can happen within days during a tcVISION Proof of Concept (POC)…

After setup and installation, a tcVISION POC is approximately 10 business days, with the customer providing a small subset of data and use case for the POC. A Treehouse Software technician will assist in downloading and installing tcVISION and conducting a limited-scope implementation of a tcVISION application. This application uses a small subset of customer data and executes on customer facilities, usually in a non-production environment. A document is provided beforehand for the customer to fill out their requirements, use cases, and agenda for the POC.

By the end of the 10-day POC, customers can replicate and test mainframe data on their Cloud target database.  It can happen that fast!
