Startup studio

A startup studio, also known as a startup factory, or a startup foundry, or a venture studio, is a studio-like company that aims at building several companies in succession. This style of business building is referred to as "parallel entrepreneurship". A startup studio is an organization that comes up with disruptive ideas and products and builds businesses alongside industry-relevant executives. The startup studio will oversee the startups from the onset of investment and will help guide the company well beyond product launch. A startup studio hires founders (either external or internal entrepreneurs who will direct the startup through “exit”). These founders come in and run each market-tested company, providing the startup with top-level mentorship, all underpinned by an enormous amount of support provided by the studio.
History.
Idealab, founded by Bill Gross in 1996, was one of the first to introduce the 'incubator industry' to the field of technology startups, and has started over 75 companies. Idealab was founded to test many ideas at once and turn the best of them into companies while also attracting the human and financial capital necessary to bring them to the market.
The startup studio trend gained momentum beginning in 2008. As of 2015, there were over 65 startup studios across the world, of which 17 had been built since 2013.
Types.
There are several types of startup studio models.
"Builder" studios.
A builder startup studio focuses on creating and developing a company, mostly from internal ideas. Notable examples of this model are Atomic, Pioneer Square Labs, Rocket Internet, and eFounders.
Unlike business incubators and accelerators, venture builders generally don't accept applications concerning their portfolio of companies, and the companies instead "pull business ideas from within their own network of resources and assign internal teams to develop them."
According to VentureBeat, Nova Spivack was "part of the early technologists who pioneered the venture production studio model. He wrote about the model in 2011 at a time when most of its production elements were still in gestation. Nova actually invented the Venture Production Studio term, calling it a 'new approach to building startups.'"
"Investor" studios.
Investor venture studios bring in early-stage external startups and help them grow by providing them both funds and expertise. Studios Betaworks and Science, Inc. fall in this category.
At the very end of the spectrum, some VC firms are growing closer to the startup studio model by intervening very operationally in the startup they invest; for instance Andreessen Horowitz and Google Ventures. However, this participation is usually limited to some areas, such as recruitment, fund raising, or PR relations.
Overview.
Business model.
Startup studios are often mistaken with startup incubators and startup accelerator, or operational Venture Capital firms.
The startup studio model is defined by three important criteria:
Unlike startup incubators or VCs, the main goal of a startup studio is to build a startup from the ground up. This implies an important involvement of time, dedication and resources to working operationally on the project for a period of time.
One focus of a startup studio is the rapid development and prototyping of new products. They work on multiple startups and projects simultaneously instead of building one project at a time.
Startup studios own an infrastructure made of pooled resources: technical tools, management processes, and a multi-disciplinary team. By building several projects a year with the same team, startups studios can re-use this infrastructure, software and best practices across products. As part of their selection process, the studio team conducts in-depth market research. Once ideas have passed the quality gate from experts, the market exploration phase begins. Both the product concept and the business model hypotheses must be validated, as well as receiving the necessary feedback obtained from partners and early adopters. 
Features in early stage ventures.
Startup studios occupy a specific place in the entrepreneurship environment, based on the amount of human and financial support they provide to the startups:
