When APTelecom was founded back in 2009, their very first piece of business was a 10Gb subsea circuit from Jakarta to Singapore. A simplistic arbitrage lease deal which created an opportunity for them to enter the submarine cable consulting market on their own terms.
That deal was quickly followed by a succession of similar deals. In parallel, given that their core competency is capacity sales, both pre RFS and in-service systems, APTelecom quickly established a niche for itself in the pre-sales and post sales market for system developers and have been delivering pre-sales for clients ever since.
At one point they even had a voice business and was fairly successfully (800 overseas termination) yet eventually divested this in early 2013 to focus on the growth of data movement sales.
