What you likely need
You're at a rare inflection point where your NASDAQ IPO credibility, YC backing, and deep quantum hardware expertise make you one of the most differentiated founders in the room at almost any gathering. The Festival events most valuable to you right now are high-trust, small-format dinners and roundtables where you can accelerate Sygaldry's hyperscaler design-partner pipeline, pressure-test your Series B narrative with tier-one investors, and quietly formalize your investor identity in quantum. You'll get the most signal from rooms that mix AI infrastructure decision-makers, deep-tech VCs who've backed hardware-to-IPO journeys, and the thin global slice of quantum hardware talent you need to recruit.
Would you attend these IRL Festival events?
We will tune and customize your Founder Festival experience to make sure you get invited to the events that would be most valuable to you.
- tacticalA closed dinner with AI infrastructure leads from AWS, Google Cloud, and Microsoft Azure to pressure-test Sygaldry's quantum-accelerated server thesis and surface the fastest path to a marquee design-partner agreement
- fundraisingA Series B fundraising roundtable with partners from Andreessen a16z Bio+Crypto, Breakthrough Energy Ventures, and Coatue who have backed hardware-to-public-market journeys, to sharpen Chad's Series B narrative while quantum-AI hype is at its peak
- positioningA dinner exclusively for founders who have taken deep-tech or quantum companies to NASDAQ or NYSE — including Rigetti Computing alumni and IonQ leadership — to swap post-IPO operator playbooks and trade warm intros to hyperscaler procurement contacts
- introsA QDNL venture partner mixer with European quantum hardware founders from the Netherlands, Germany, and UK ecosystems to identify co-investment targets that could double as strategic partners or acqui-hire candidates for Sygaldry
- hiringA Yale PhD quantum physics alumni dinner co-hosted with Rigetti Computing alumni to recruit senior quantum hardware engineers into Sygaldry's founding team, leveraging Chad's reputation as the builder of the first publicly traded quantum company
- introsA happy hour for angel investors and emerging-manager LPs already active in deep-tech to help Chad formalize his quantum deal flow into a small syndicate, using his h-index 22 research credibility and Rigetti Computing track record as the anchor pitch
- positioningA technical roundtable with AI infrastructure researchers from MLCommons, Epoch AI, and top arXiv-active ML labs to co-design a credible benchmark framework for quantum-accelerated inference that Sygaldry can publish as a white paper or peer-reviewed submission
