Launch Deck was designed and built for innovative entrepreneurs and ambitious investors. We realized the process of raising capital was difficult and startups weren’t maximizing their potential or connecting with the right investors. That’s why we created Launch Deck, a two-sided marketplace...

As answered by people managing LeetCode and Launch Deck by Hyperspace.
Launch Deck by Hyperspace's answer:
Pre-seed and seed founders raising $250K-$2M from accredited investors who want flexibility and control. Perfect for founders with warm investor leads, angel networks, or those who want to test private outreach before going public. Not for community raises from thousands of micro-investors.
Launch Deck by Hyperspace's answer:
Only fundraising platform with public/private toggle—go public for investor discovery or stay private for targeted outreach, then switch anytime. No campaign deadlines, no platform fees (0%), no SEC filings for Reg D raises. Build a customizable pitch site (deck, video, data room, terms) in one shareable link with full control over timing and visibility.
Launch Deck by Hyperspace's answer:
If you want control over your raise without forced public campaigns or all-or-nothing deadlines. Unlike Wefunder/Republic that require public campaigns with 7-8% fees and $30K+ compliance costs, Launch Deck is free, launches in days not months, and lets you choose your approach. Built by investors for investors (Hyperspace Ventures uses it for their own deal flow).
Launch Deck by Hyperspace's answer:
Built by Hyperspace Ventures (software development and investment firm) to manage their own deal flow. They needed a platform that gave founders control over visibility and timing while providing investors the features they actually wanted—not just marketing fluff. Turned their internal infrastructure into Launch Deck so other founders could raise efficiently.
