Sources: SEC EDGAR submissions API (formerNames) + full-text search, efts.sec.gov. — research profile — Dr. Avi Katz is the founder, chairman, and CEO of GigCapital Global, a Palo Alto-based SPAC platform he launched in 2017 after selling his fabless semiconductor company GigOptix (NYSE: GIG) to Integrated Device Technology for $250 million. A graduate of the Israeli Naval Academy with a B.Sc. and Ph.D. in Materials Science from the Technion, Katz spent six years at AT&T Bell Laboratories before moving into executive roles across high-tech companies, including CEO stints at Intransa and Equator Technologies (sold to Pixelworks for $110 million). He holds over 70 U.S. and international patents and has authored more than 350 scientific works. GigCapital markets itself under a "Private-to-Public Equity (PPE)" and "Mentor-Investor" methodology, positioning its approach as more hands-on than a conventional SPAC, with an emphasis on guiding late-stage private companies through and beyond the de-SPAC process. The first vehicle, GigCapital1, raised $143.75 million in December 2017 and merged with Italian CPaaS company Kaleyra in November 2019. Subsequent deals include GigCapital3's merger with electric vehicle maker Lightning eMotors (ZEVY) in May 2021, GigCapital4's merger with AI specialist BigBear.ai (BBAI) in December 2021, and GigCapital5's combination with medical imaging firm QT Imaging Holdings (QTIH) in October 2021. GigCapital7 raised $200 million in September 2024 and is pending a merger with micro-reactor developer Hadron Energy. GigCapital8 raised $220 million in October 2025 and has signed a letter of intent with Quantisimo Corp., a WISeKey/SEALSQ vehicle targeting a consolidated $2 billion quantum platform. The latest vehicle, GigCapital9 (NASDAQ: GIX), priced a $220 million IPO in January 2026 (closing at $253 million with over-allotment), targeting aerospace and defense, cybersecurity, quantum systems, and AI/ML companies. Katz's board compositions across the GigCapital vehicles draw heavily on military, defense, and technology figures, including retired admirals David Ben-Bashat and Omri Dagul, retired General Avi Mizrachi, Ambassador Adrian Zuckerman, and seasoned technology executives like Bryan Timm and Luis Machuca. Christine Marshall serves as CFO across multiple vehicles. The sponsor has evolved its deal structure over time, more recently using rights instead of warrants—each unit in GigCapital9 comprises one share plus one-fifth of a right—to reduce complex derivative accounting while still offering a path to additional equity. D. Boral Capital has served as sole bookrunner on the most recent offerings, with DLA Piper as legal counsel. While the sources do not detail post-deal stock performance or redemption rates, some cautionary signals are visible. GigCapital6 reportedly slashed its planned IPO size by 43% in early 2022, cutting $150 million from its target, suggesting difficulty attracting capital in…

It stated a vehicle count (nine vehicles) that does not reconcile with the record we counted: 7 vehicles — 1 in the live database and 6 SEC-verified prior vehicles.

Full sponsor record →Why the sponsor matters
The thirty-second version, for anyone who has never traded a SPAC.
A SPAC is an empty listed company; the sponsor is the only substance it has before a deal. They pick the target, negotiate the terms, and typically hold founder shares — equity they received nearly free — which pay off for them even in deals that lose public holders money. A sponsor’s prior vehicles are the closest thing to evidence about how this one ends.
How the founder-share incentive works is covered in our plain-English guide to the sponsor promote.
In plain English
Cash in trust / trust per sharethe cash the company is holding for each public share
Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.
Dilutionhow much of the company new shares take from you
Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.
De-SPACthe day the SPAC becomes the real company
The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.
