About Us

TEMBO shares the view of the broad IT community that the IBM i (and its predecessors AS400, S36 and S38) is still the best and lowest cost, high volume transaction processing server in the world. More important is that we recognize the value of purpose written applications for specific business processes, as well as the encapsulated data that was captured over years.

 

Adsero Optima™ (AO) consists of a range of tools that are built and maintained by us, to assist IBM i users to unlock this value in IT investments. The primary focusses are innovation and provision of application modernization solutions to optimize ROI on proven applications and data. Although our knowledge base is spread on full spectrum application modernization and improving efficiencies within IT, our core focus is to assist companies to leverage the value of integrity and existing historic data.

 

We do believe that if used properly, RPG IV and DB2 (SQL) on IBM i will outperform any other language and database combination (from any supplier) for high volume, commercial online transaction processing.

Our Vision

With the focus on IBM i and its predecessors (AS400, S36 and S38), our vision is to build processes and tools that will ensure maximum ROI to these technology users. Our vision is also to assist these users further by using our products, training, examples, etc. to extend their initial investment in their IBM i, as well as their competitive advantages of specialized processes built into their computer systems, by at least another 20 years.

Your success is our success.

Why ‘Adsero Optima™’?

Adsero is a variation of the Latin verb ‘assero’, which means ‘to assert or claim’. Combined with ‘optima’ it translates as:

 

‘We claim excellence’.

 

The fundamental objective and drive behind Adsero Optima is to facilitate you to ‘Reclaim your Heritage, unleash your data value’, as we fundamentally believe that there is enormous untapped value in your heritage (legacy) systems and data. This assertion is supported by extensive research and opinion by the leading consulting (Aberdeen, Butler Group, Forrester Research, Gartner, IDC, et al) houses of the world.

The Adsero Optima™ (AO) suite of products is developed, distributed and owned by TEMBO Application Generation (Pty) Ltd (referred to as ‘TAG’), a subsidiary of the TEMBO Group of companies.
