Their first products were Pascal and assembler implementations for the NASCOM 1 and 2 kit-based computers, followed by Pascal and C for ZX Spectrum computers, as well as a BASIC compiler for this platform and a C compiler for CP/M. While compilers for the ZX Spectrum were typical products for this platform, with integrated editor, compiler and runtime environment fitting in RAM together with program's source, the C compiler for CP/M was typical for this operating system, batch operated, with separate compilation and linking stages.^{[citation needed]}

Their most well-known products were the Devpac assembler IDE environments (earlier known as GenST and GenAm for the Atari ST and Amiga, respectively). The Devpac IDE was a full editor/assembler/debugger environment written entirely in 68k assembler and was a favourite tool among programmers on the Atari GEM platform.

HiSoft also sold HiSoft BASIC and Power BASIC, HiSoft C Interpreter for the Atari ST, Aztec C, Personal Pascal, and FTL Modula-2. They also produced WERCS, the WIMP Environment Resource Construction Set.

The business was created in 1980 and was based in Dunstable, Bedfordshire before relocating to the village of Greenfield in the same county.

In November 2001, HiSoft's staff were employed by Maxon Computer Limited, the UK arm of MAXON Computer GmbH.^[2] to work on Cinema 4D.^{[citation needed]}

David Link, the founder and owner, ran a café (^[3]) in the village of Emsworth for a year until July 2007 and a restaurant/bar/guest house(^[4]) in Shanklin, Isle of Wight, from 2010 until January 2015.
