Ahrefs is a multinational team with roots in Ukraine and headquarters in Singapore. We are a lean start-up company. We value making
meaningful and easy-to-use products. We shift things fast to give our customers what matters most to them, and to keep us ahead of the game. Our
motto is "First do it, then do it right, then do it better."
Ahrefs' history dates back to 2011, when we introduced the first version of Site Explorer after a year of preparation and data
mining. Site Explorer disrupted the stagnant field of backlink analysis and kick-started a new round of competition among SEO tool
providers. It quickly became one of the world's best backlink analysis tools.
From our humble beginnings, Ahrefs has steadily grown. We started out with a cluster of six servers, and gradually evolved
to our current, powerful 60 teraflops system. Today, we update our index with the freshest backlinks on the web every 15 minutes,
and the crawler processes up to 5 billion pages a day. That's more than a third of what Googlebot does!

from Wikipedia Software as a service (SaaS) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally
hosted. It is sometimes referred to as "on-demand software", and was formerly referred to as "software plus services" by Microsoft.
SaaS applications are also known as Web-based software, on-demand software and hosted software. The term "Software as a Service" (SaaS)
is considered to be part of the nomenclature of cloud computing, along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS),
Desktop as a Service (DaaS), managed software as a service (MSaaS), mobile backend as a service (MBaaS), and information technology management as
a service (ITMaaS).
SaaS apps are typically accessed by users using a thin client, e.g. via a web browser. SaaS has become a common delivery model for many
business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD
software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), Management
Information Systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning
management systems, content management (CM), Geographic Information Systems (GIS), and service desk management. SaaS has been incorporated into
the strategy of nearly all leading enterprise software companies.
According to a Gartner estimate, SaaS sales in 2018 were expected to grow 23% to $72 billion.

StarOffice, which Sun Microsystems acquired in 1999 for internal use.
OpenOffice included a word processor (Writer), a spreadsheet (Calc), a presentation application (Impress), a drawing application (Draw),
a formula editor (Math), and a database management application (Base). Its default file format was the OpenDocument Format (ODF), an ISO/IEC
standard, which originated with OpenOffice.org. It could also read a wide variety of other file formats, with particular attention to those from
Sun open-sourced the OpenOffice suite in July 2000 as a competitor to Microsoft Office, releasing version 1.0 on 1 May 2002.
In 2011 Oracle Corporation, the then-owner of Sun, announced that it would no longer offer a commercial version of the suite and donated
the project to the Apache Foundation.
Apache renamed the software Apache OpenOffice. Other active successor projects include LibreOffice (the most actively developed) and
NeoOffice (commercial, only for macOS).
OpenOffice.org was primarily developed for Linux, Microsoft Windows and Solaris, and later for OS X, with ports to other operating
systems. It was distributed under the GNU Lesser General Public License version 3 (LGPL); early versions were also available under the Sun

in 10 days.
On July 6, 2012, Mozilla announced the company was dropping the priority of Thunderbird development because the continuous effort to
extend Thunderbird's feature set was mostly fruitless. The new development model shifted to Mozilla offering only "Extended Support Releases",
which deliver security and maintenance updates, while allowing the community to take over the development of new features.
On December 1, 2015, Mozilla Executive Chair Mitchell Baker announced in a company-wide memo that Thunderbird development needs to be
uncoupled from Firefox. She referred to Thunderbird developers spending large efforts responding to changes to Mozilla technologies, while
Firefox was paying a tax to support Thunderbird development. She also said that she does not believe Thunderbird has the potential for
"industry-wide impact" that Firefox does. At the same time, it was announced that Mozilla Foundation will provide at least a temporary legal and
financial home for the Thunderbird project.
Since the memo in 2015, Mozilla has brought Thunderbird back in-house in an announcement on May 9, 2017, and continues to support its
development. The Thunderbird development team has also expanded by adding several new members and has undergone an overhaul on security and
