Once, they shaped all of Terragen life. Unimaginably powerful and wealthy mercantile corporations, they spanned star-systems and drove commerce and economics throughout the known worlds. They manipulated entire polities and even worlds with ease, waging a never-ending battle of memetic subversion, a war to win the hearts and minds and pockets of their potential customers.
Today the megacorps are largely limited to the NoCoZo, various Free Zones, and any regions, especially in the Outer Volumes or along some of the Deeper Covenant trade routes where, like tenacious weeds, they can establish a foothold free of Sephirotic and hyperturing interference.
Yet for all this they can in the right environment be as powerful and influential as ever, at least within their own spheres of influence, and toward ordinary sapients who are not of a sufficiently high toposophic level to resist their persuasion.
In an uncertain universe where resources on the Periphery were limitless, where fads change every day, where clarketech and meme-relics left by powers from the higher toposophics continually excited the populace and stirred up new fads and demands, the megacorps flourished, and continue to flourish. Avoiding the no-go areas ruled by skittish Caretaker Gods, rogue hyperturings, or feral autowars, they develop their offices in Free Zones throughout the galaxy. Sapients everywhere flock to them, because if you do not have a hyperturing or god looking after you, to be in the employ of the Company is the next best thing.
As long as demand outpaces supply, as long as there are wealth and energy-credits and data processing-allowances to be made, as long as fads drive markets, the mighty transplanetaries and megacorporations will be there to take your erg-credits.

Clade of aioid business beings, descended from the First Federation Era New Mars think tank Contelligence.

Politically the Contelligence clade has been neutral, with pacifist leanings.

- GeneTEK - Text by M. Alan Kazlev
Important interplanetary age biotech megacorporation, they incorporated themselves into the "biopunk" Genetekker culture/clade. One of the few corps to survive the nanoswarms, they dominated the First Federation biotech industry, before ossifying into House Genen. Some small hyperturing-run neo-GeneTEK type biocorporations can still be found flourishing in the Zoeific Biopolity to this day.
- Hidalgo Emergent Order - Text by Anders Sandberg
Hidalgo Emergent Order was a very expansive tweak-cyborg clade/corp that flourished during the late Federation and Expansion ages, setting up asteroid-based societies in the region between Capella and Pollux and becoming an important regional superpower. Using aggressive in vitro techniques they cloned large populations, but were unable to prevent Conver Ambi from gaining a monopoly on vital nanodesign objects, giving them an ever stronger hold on the Order. Eventually most of the Order joined the Conver Ambi, with the exception of a number of habitats that committed collective suicide.

Megacorp-Polity that developed out of the Hopomane Empire. The Network rebuilt the links to the region and set itself up as the rulers.

- Hyperion Corporation - Text by M. Alan Kazlev
One of the ten top megacorps of the First Federation and Expansion age eras, Hyperion actually predates the First Federation, being one of the few megacorps to survive the nanotech swarms. But the failure to win the Stargate development race was a blow to the prestige of the corporation.

During the imperial period it was aggressively expansionist, using profitable deals with various government factions as well as opportunistic alliances with various hyperturing guanxis to further its growth and become an interstellar megacorp. The corp was made a Conver Ambi subsidiary, and disappeared even before the start of the Second Empires War.

Neuropoll Inc. is a polling firm that dates back to the Second Federation, often exploiting advanced psychological and neurological methods to extract as much data they can. They were most known for the neuropollsters, when in the early 6300s, 20,000 citizens of New Emerton (Smith sector, NoCoZo) were wired with a system making it possible for Neuropoll to measure their reactions to a variety of products, everyday phenomena and their desires; this data is then mined to find trends, mood estimates and fashion vectors.

- Pi Hermes - Text by Anders Sandberg
Among the more interesting organisations, the original Pi Hermes began during the early Federation period as a detective agency with an unique concept: they recorded virch immersives based on their cases, exciting real-life documentaries about the work of investigators, in which the vircher actually became the detective working on a real (not a fictional or simulated) case as it happens. So successful was this concept that every so often a Pi Hermes media clone is established. At the present stardate there are several thousand pihermes throughout the Inner Sphere (mostly on NoCoZo worlds).

- Transfinity - Text by Anders Sandberg
Nanofacturing subsidiary to Vollmark, an interplanetary era home microtronics corporation (2402-2494). Transfinity products became very widespread especially on Earth, where their matter compilers, microrepair systems and genius cleaning fluids became market leaders during the late 2400's. While very popular, Transfinity had a reputation for sloppy security assurance and their products were several times hacked or subverted. Due to their ubiquity, the consequences were far more serious than nanohacks against competing products, and as the situation on Earth worsened many accused the company of criminal negligence. In a landmark case in 2493 the Earth Trade Association and UN Nanodefence Council ordered the closing of the otherwise successful corporation. Although nanohistorians have discounted the theory that it was the Transfinity Level 6 Microrepair Swarm (Goliath) that was the true origin of the 2500 nanoswarm, it remains certain that some of the badly secured nanosystems became integrated in co-opting swarms.

- World-disk Software - Text by Ernst Stavro Blofeld
London (Old Earth) -based, Information Age corporation; World-disk Software was one of the first companies to introduce neural-networked file system compression. Browsing this file system was done via a 'library' interface, which, due to the unique compression systems would warp and wrap and distort all dimensions inside the construct. The only way to find your way around was with the aid of the Librarian daemon, who manifested in the shape of an enchanted orangutan. The software later became the model for the Alexandria II Bibliotech project.
- Xweak - Text by Anders Sandberg
Disinformation corporation, based in Cyberia. Xweak specializes in high-level disinformation, mainly with hyperturing customers. Xweak announced its existence publicly in 6094 through a series of carefully timed publicity stunts across civilized space, all in the form of mysterious apparent crimes. As various beings began to investigate them, they discovered leads to further enigmas; the entire campaign consisted of an escalating series of puzzles finally leading to the corporation.
