Hi 👋
We are the OG team behind the "comment a word to get a DM" trigger that changed social media forever.
Our AI-powered automations help 1M+ creators and brands engage with audiences across Instagram, Messenger, WhatsApp, and TikTok. Billions of messages are sent through the platform every year, helping our customers generate leads, increase sales, and build a strong following with their audience.
We're 400+ people across three continents with R&D hubs in Amsterdam and Barcelona.
We keep Manychat running smoothly under high load every single day and make sure it’s ready to scale even further. We do it by combining strong engineering foundations with AI tools that let us move faster without cutting corners. And we're the ones who shape and own what gets built.
We take technical debt seriously, invest in code quality, and give engineers real ownership over complex problems. You know what you own and you can see where your work lands.
Our tech stack is designed for speed and durability. Under the hood we have:
Backend: PHP, Python · PostgreSQL, Redis, ElasticSearch, NGINX + Lua, AWS, FastAPI
Frontend: TypeScript, React, Redux · Jest, Playwright
Mobile: Swift, Kotlin · SwiftUI, TCA Coroutines, Jetpack Compose
Data & AI: Snowflake, Python
