Build production-ready apps with AI

You built the demo in a weekend. Now you need auth, a prod-grade database, real-time events, AI observability, cron jobs, email, monitoring… and you needed them yesterday. We spent a decade at our previous startup, building a $500M platform while scaling to millions of users and customers like Meta & Netflix. Now we're standardizing how web applications are built with an open-source framework and AI App Builder, so non developers can build reliable production apps and not just prototypes. Modelence is a batteries-included platform with a dedicated web app framework that's designed for building production grade apps with AI, abstracting away the standard building blocks: - Authentication - Database - Hosting - AI integration - Cron jobs - Live / real-time data - Email integration - Monitoring Most AI app builders just stitch together multiple services and existing frameworks. The reliability drops hard because integrations between different parts break. Modelence defines a single full-stack framework with dedicated cloud infrastructure, where these integrations are already built into the framework and don't need to be built for every app.

Unlock revenue per employee with AI-powered headcount management

Modus helps companies hire and retain only the people they need instead of becoming bloated messes. Modus connects your HRIS, ATS, and analyzes extensive data across your organization so leaders can detect, inspect, and correct their workforce plans - without relying on spreadsheets or complex systems. Lin experienced these challenges firsthand as a VP BizOps at HashiCorp, scaling from 100 employees to IPO, while Chris and Amar faced similar issues scaling 40+ person teams as a fractional CTO. They’re motivated by the belief that companies should have the least number of employees possible.

Biopesticides that are safe for humans and bees.

Molagri develops safer, more effective pesticides for agriculture. We design biopesticides that hit a precise molecular target unique to pest insects, knocking out pests while sparing pollinators, beneficial insects, and the wider ecosystem. By modeling how pests are likely to evolve, we stay a step ahead of resistance, keeping our products effective against the pests of today and tomorrow. The higher efficacy and biobased production will also contribute to emissions reductions in both manufacturing and field use. Our founders are PhD lab mates from the University of Toronto who have worked together for six years and published in Nature Communications and Nature Microbiology.
