Event Overview

On Thursday, September 17, 2026, Protostar Inc. will host a free seminar titled "Capital Strategy Fundamentals Every Founder Must Know: Seed-Round Ownership Ratios and Valuations You Can't Afford to Overlook." Targeted at pre-incorporation entrepreneurs and founders within their first three years of business, the session will provide expert guidance on structuring seed-stage capitalization tables and planning ahead for future fundraising rounds, talent acquisition, and potential M&A exits.

Speaker and Key Takeaways

The in-person seminar will be held at GROWTH Bunkyo Iidabashi, featuring Toshihide Okayasu, a Certified Public Accountant (CPA) from Okayasu CPA Office with extensive experience in startup finance advisory and corporate auditing.
