About us
Startup Investor Accelerator builds stronger startup companies that are more investible and grows new Angel Investors in local ecosystems.
We will run a variety of events about how to be effective as a startup founder, how to get into Angel Investing as a new investor and work to connect people to resources in the community.
This program is connected to the Seattle Angel group run by Mossy Ventures. Workshops and meetups will resemble the types of things we have done in the past in http://meetup.com/Seattle-Angel , http://meetup.com/Startup-Investor-Accelerator, http://meetup.com/Startup-Investor-Accelerator-Estonia

TAAC #9 Demo Day: Startup Showcase & Investor Selection
·OnlineOnline1 attendee from 11 groups# TAAC #9 Demo Day: Startup Showcase & Investor Selection
Join us for the Grand Finale of the 9th Trans-Atlantic Angel Conference (TAAC) as our investor cohort makes its final investment decision.
TAAC is a unique, hands-on angel investing program where new and emerging angel investors learn by doing—evaluating real startups, conducting due diligence, and participating in an actual investment process.
Over the past three months, approximately 20 investors have reviewed 44 early-stage startups, assessing business models, financials, market opportunities, customer references, and growth strategies. Through multiple rounds of evaluation and due diligence, they have narrowed the field to five exceptional finalists.
TAAC #9 Demo Day is the culmination of that journey.## What to Expect
✨ Live pitches from the finalist startups
✨ Insights from the investor due diligence teams
✨ The final investment decision and winner announcement
✨ Audience Choice Award voting
✨ Networking with founders, investors, mentors, and ecosystem builders## Meet the TAAC #9 Finalists
