Agentic Labs

AI system design tools for dev teams

Agentic Labs is making software design and architecture less painful by building AI into the process. Today, developers have no shortage of tools for instantly creating chunks of code, but designing the systems that integrate this code is the hardest and most manual part of software engineering. Our first product is Glide, an AI-first editor purpose-built for writing technical design docs. It connects to your codebase and saves your engineering team time on triage, planning, and implementation of complex code changes.

Agentin AI logo

Agentin AI

AI Agents that automate enterprise software processes

At Agentin AI, we build Agents that move data and take actions across enterprise systems, like Salesforce, NetSuite and SAP. These agents are difficult to build because each enterprise heavily customizes their systems but we solved that by training our Agents to learn and adapt from failures, applying reinforcement learning techniques we developed.

Aglide logo

Aglide

Connect every disconnected app to your SSO.

Our mission is to secure access to every enterprise application. Aglide SSO lets security and IT teams connect non-standard and legacy apps - from banking portals to social media logins - directly to their existing identity provider (Okta, Entra, OneLogin, Ping, etc.), with no need for app-side integration. Once connected, these apps behave like any other IdP-managed service: policies like MFA, Conditional Access, RBAC, and audit logging just work, and end users access them through SSO only. Customers use Aglide to secure both individual apps (e.g., legacy banking portals, Discord, Squarespace) and sensitive shared accounts (e.g., AWS root, social media). Our agentic identity technology means Aglide works with any app out of the box - no integration catalog, no custom scripting. Today, customers from fintech decacorns to global media companies rely on Aglide’s zero-trust, end-to-end encrypted platform to complete their identity stack.

Aidy logo

Aidy

Mobile app helping people better manage chronic health conditions

Aidy is a mobile app that helps people live fuller lives with chronic health conditions, beginning with Inflammatory Bowel Disease (Crohn’s Disease and Ulcerative Colitis). Our app lets users easily log their symptoms, diet, and treatments, then uses clinical indices to track disease severity and trends over time. Aidy excels at identifying patterns between diet, treatment adherence, and symptoms, giving our users a much more comprehensive and up-to-date picture of their condition to supplement clinician care. Previously in our careers, both Max and Peter worked in health in different capacities. At the Rockefeller Foundation and the United States Senate, Max worked in public health policy and COVID-19 response, while Peter worked as an ML researcher for a number of biotech companies. After a lengthy “pivot hell” we decided to finally listen to a friend with IBD who insisted that there weren’t any decent apps to help people live with the disease. Pretty quickly, we discovered how LLMs and regular structured questionnaire responses could provide a level of patient empowerment not possible before for chronic diseases. From there, Aidy was (re)born!

AirCaps logo

AirCaps

AR glasses to better understand, remember and learn from conversations

We're building lightweight AR glasses that help you understand, remember and learn from conversations. AirCaps displays captions, translations, summaries and proactive insights for your conversations in your field of view in real-time. We're starting with real-time captions for hearing loss. We did $90K in sales in October (grew 6.5X from September), have users averaging 6h+ daily use, and went viral on TikTok (75M views). Madhav (Yale CS, MIT Media Lab audio AI) and Nirbhay (Cornell CS) have been obsessed with smart glasses for 11 years—building Google Glass apps from age 13. People spend 3 hours a day in meaningful conversations—negotiations, interviews, pitches, conflicts, first dates. They struggle to comprehend 25-50% of them, forget 70% within 24 hours and 90% within a week, and have no way to learn and improve from their conversations. AR glasses are the only form factor that can augment conversations without disrupting them. They keep your hands free, allow you to maintain eye contact, provide information exactly when needed, and have unfiltered access to everything you hear and see. In 5 years, 4.7 billion smartphone users will use smart glasses. But today's AR glasses are too heavy, conspicuous, and power hungry while failing to provide utility: generic toys without purpose. Conversations demand real-time, hands-free, eyes-up assistance precisely when you can't look away—the killer use case to kickstart mass adoption. If we're right, we'll own the gateway to the next interface for technology.
