Startup Accelerators Aren't Banking on Exits Any MoreAccelerators are increasingly selling a range of services to generate ongoing revenue, without waiting years for startups to be sold.

Within only a decade, accelerators have become a mainstay of startup ecosystems in regions around the globe. Throughout this period, the accelerator business model has continued to evolve. Still in the Global Accelerator Report 2015, a majority of accelerators globally still indicated that they intended to follow the traditional "cash-for-equity" model, first established in 2005 by Y Combinator, which involves investing a small amount of seed money in a startup in exhange for equity. Investments typically are around $25,000 on averag in exchange for between 5 percent and 10 percent equity.

This model has now been abandoned by a majority of accelerators, as highlighted by the recently publishedGlobal Accelerator Report 2016. The report highlighted that only 32.7 percent of accelerators predict that they will generate revenue from exits in the future, a significant shift from 2015.

加速器的主业务的原因ss model is, most likely, the small number of exits -- 178 reported in 2016 -- which has proven insufficient in funding their operations. Morevoer, exits usually do not occur earlier than three to five years into a startup's lifecycle, denying accelerators a profit on investment for several years. To make up for the expensive day-to-day upfront costs of operating their programs, accelerators have deployed new models that allow them to generate revenue.

These changes enabled the industry to keep growing year-on-year. According to new findings in the 2016 Global Accelerator report more than $206M (up 8 percent) was invested into 11,305 (up 28 percent) startups across five major regions, including the United States and Canada, Latin America, Europe, the Middle East, and Asia and Oceania. USA continues to be the leading country both in terms of startups accelerators and in dollars invested via accelerators.

Nearly all (90.4 percent) of accelerators globally relied on, and continue to explore, new models of revenue generation. These include charging for mentorship, subletting office space, hosting events and working with corporations. Revenue from corporations has seen the largest increase. More than half (52.1 percent) of accelerators are at least partially funded by a corporation, and 67.2 percent aim to generate future revenue from services sold to corporations.

On the one hand, this is because corporations are discovering thatacceleratorsare an efficient and effective way to engage with startups. On the other hand, accelerators understand that corporations can help them fund operations in the short-to-medium term (exits are often far out). They improve the prospects of their portfolio companies that can potentially sell to, raise funds from, or be acquired by these corporations.

Corporate revenue generated by accelerators came from two main sources in 2016: corporate partnerships, generally in the form of a white-labeled or jointly-run acceleration program created by the accelerator on behalf of the corporation, and corporate sponsorship packages sold by accelerators.

It is clear that accelerators have changed their operating model globally in a significant way over the last few years. The accelerator model whilst still aligned with its predecessor's original vision of nurturing disruptive companies - is different in a number of ways. These new accelerators possess a diversified revenue model, often focus on a specific vertical and work closely with corporations. In the coming years and beyond, it will be interesting to see what new pivots the global accelerator industry will undergo in an attempt to achieve sustainability and less reliant on government grants and private funding.
