Investment application process

Every entrepreneur or start-up founder can apply for investment or for the ability to present to the Keiretsu Forum. The application form is in English and must be completed in English. Keiretsu Forum is an international network, and using a single language makes it accessible to investors from all over the world.

Application Submission

Companies, start-ups and entrepreneurs seeking investment complete a free online application.

Committee Pre-Screening of Applications

Your application will be pre-screened by Forum members with relevant industry knowledge (e.g. software, hardware, life sciences, real estate, telecommunications, media, food industry, clean technology, etc.). Based on the pre-screening team’s recommendation, 7 to 10 companies are selected for a deal screening where they will present their plans to investors.

Deal Screening

Presentations are limited to 15 minutes and no more than 10 PowerPoint slides. Keiretsu Forum recommends a 7-minute presentation followed by an 8-minute Q&A session.

Deal screening is a democratic process where 15 to 20 investors discuss each presentation, expressing their interest and voting anonymously. At the end of each deal screening, 4 to 5 companies are selected to present at a Keiretsu Forum meeting.

The screening committee may recommend that a company must achieve certain milestones and goals or answer additional questions before it is invited before the Forum.

Keiretsu Forum Meeting

Companies selected through the deal screening present to the full Forum. The presentation slots are 20 minutes long. We recommend a 10-minute presentation followed by a 10-minute Q&A session. After each presentation, interested investors complete an interest form (Gold Sheet). After the completion of all presentations, entrepreneurs are excused and Forum members discuss the investment opportunities.

Due Diligence

The companies selected by investors (Gold Sheet) enter into a due diligence phase. It is common for one or two investors to lead the entire due diligence process. While investors may collaborate, each of them makes their individual investment decisions.

Global investing (Multi-Chapter Investing)

Each company has the opportunity to secure investment from any part of the Keiretsu Forum global network and to present to any chapter of the Keiretsu Forum.
