Superblocks
Superblocks is a New York-based enterprise software company that lets organizations build, deploy, and govern AI-generated internal applications. Its AI agent, Clark, turns natural-language prompts into full-stack apps backed by extensible React code, while enforcing an enterprise's existing security policies, data permissions, design standards, and audit requirements. The company positions itself as the governed, IT-controlled answer to consumer 'vibe coding' tools, serving teams that need to ship internal software quickly without introducing security and compliance risk.
Dazzle AI
Dazzle AI is a Palo Alto consumer-AI startup founded by former Yahoo CEO Marissa Mayer that aims to close the gap between what people want to do and what they can actually do with AI. Emerging from the assets of Mayer's earlier venture Sunshine, Dazzle is building a consumer-facing AI application - described as a next-generation personal assistant - and raised $8 million in seed funding in December 2025 at a $35 million post-money valuation, led by Forerunner's Kirsten Green.
Arcade
Arcade is a San Francisco software company that lets go-to-market teams build interactive product demos in minutes instead of weeks. Using a Chrome extension or desktop app, users record their product, then add pan-and-zoom, hotspots, synthetic voiceovers, and branching paths to create clickable 'arcades' that can be embedded in websites, emails, and social posts. Founded in 2021 by former Atlassian colleagues Caroline Clark and Rich Manalang, the company turns the old 'request a demo' wall into a 'try before you buy' experience, and is used by more than 14,000 companies including Zapier, Red Hat, and New Relic.
Manifest OS
Manifest OS is a New York-based legal technology company building the operating system for AI-native law firms. It powers a unified law-firm brand, Manifest Law, with an end-to-end AI platform and centralized back office, replacing the billable hour with flat, outcome-based pricing. Starting in business immigration, the company raised a $60M Series A at a $750M valuation in April 2026, reported as the largest Series A in legal-tech history.
Juicero
Juicero was a San Francisco hardware startup that built a Wi-Fi-connected, $699 cold-press juicer paired with proprietary single-serving produce packs sold by subscription. Backed by roughly $118.5 million from Kleiner Perkins, Google Ventures, and Campbell Soup's venture arm, it became a Silicon Valley cautionary tale in 2017 after Bloomberg showed the packs could be squeezed by hand just as effectively as the machine. The company suspended sales in September 2017. The juicero.com domain now hosts an unrelated sparkling-water brand revived in 2025.
Nooks
Nooks is an AI Sales Assistant Platform (ASAP) that automates the grind of outbound sales - parallel dialing, prospect research, call coaching, and follow-up - so reps can spend more time having real conversations and less time leaving voicemails. Founded by three Stanford classmates in 2020 and headquartered in San Francisco, the company has raised $70M, including a $43M Series B led by Kleiner Perkins, and counts Seismic, Greenhouse, Brex, Deel, and HubSpot among its customers.
