The company supports AI labs, data platforms, vertical AI builders, and enterprises operating in regulated environments.

- BeFake
Participated · Seed · Aug 2023
BeFake is an AI-augmented social network from Alias Technologies that combines push-notification driven front-and-back photo posts with generative-AI image transformation via in-app presets or custom prompts. The app runs a Stable Diffusion pipeline with a custom denoising loop and proprietary components tuned for social photos, applying changes typically in under 30 seconds (often under 10), and users spend on average at least 10 minutes per session designing creations. Launched on the App Store and Google Play this month, the product supports sharing to friends, a discovery feed, and toggling between original and AI versions. BeFake generates revenue via subscriptions that pay for compute time (priced $2.99/week, $9.99/month, or $99.99/year) and offers a daily 20-minute free window via push notifications. The company is a 12-person, remotely distributed team founded as Alias Technologies in 2021 by Kristen Garcia Dumont and Tracy Lane, former Machine Zone executives. Founders say they will leverage gaming-derived approaches to rapid iteration and community building as the product moat and to adapt features to user tastes.

- Smartlens
Participated · Series A · Jul 2023
Smartlens’ flagship product, miLens, is the world’s first electronics-free soft contact lens capable of continuous intraocular pressure (IOP) measurement. The microfluidic lens pairs with the firm’s AI-powered smartphone imaging platform to capture real-time pressure data and deliver predictive analytics for glaucoma and ocular-hypertension patients. The company is running a multi-site U.S. pivotal trial and has advanced regulatory preparation, manufacturing scale-up, and clinical validation. Market demand appears strong: a Market Scope survey of 166 ophthalmic practitioners showed 96.2 % intend to adopt miLens once available. After securing FDA clearance, Smartlens plans an expedited commercial launch and expects its platform to enable earlier, data-driven interventions that could slow disease progression for the 180 million people affected by glaucoma and ocular hypertension worldwide. The recent $5.2 million bridge financing provides the capital needed to complete the clearance process and prepare for market entry.
