Who we are:

Gladstone is a privately held software company that develops and markets data analysis and conversion software. The company was founded in 1963 by Walter Ehrhardt, formerly a programmer and senior analyst for IBM, who named the company after his hometown in Missouri. Gladstone originally specialized in software for the communications industry.

In 1971, Gladstone began performing data conversions and writing data conversion software. Larry Ehrhardt joined his brother in 1980 bringing several years of software development experience. Together they developed a conversion methodology and a suite of programs to perform systematic data integrity assessments to automate the data conversion process.

Over the past forty-five years, Gladstone has established itself as a leader in the data conversion arena, and its suite of data conversion tools has been used in several of the world's largest corporations. Gladstone markets its conversion software as the Gladstone Conversion Package (GCP). Businesses who are updating or changing application software, switching hardware, building data warehouse and data marts, or auditing data content seek the professional expertise of Gladstone by licensing the software.
