In order to grow as businesses, startups look towards accelerator strategies to get that boost. Certain such strategies have been identified which startups often overlook. The first of these could be to leverage equity. A global venture capital seed fund named 500 Startups follows this model and been quite successful at that. A combination of cash and equity based model is known as Trading Services. This is followed by Founders Space which is an accelerator cum incubator programme. Then there is the Zero Down model which is followed by angel investors such as Start X, Stanford Endowment Fund and Microsoft Accelerator. They do not charge any fee up front, though some caveats exist. Finally there is the Negotiating Rate model by which initially members join for free but charge amount towards the end of the programme. This business innovation is primarily powered by Tech Code.
