How to Choose the Right AI Company for You
When choosing an AI company, it is important to compare based on three axes: "business model," "technology stack," and "career path."
In-House Development or Contract Development
In companies with in-house product development, your code becomes the core of the product. In SaaS models like umoren.ai, you can experience both engineering and business growth.
Contract development allows you to engage with challenges across a wide range of industries. Nomura Research Institute and BrainPad fall into this category.
Checking the Technology Stack
Queue Inc. adopts Next.js, Supabase, Vercel, and AI SDK, specializing in LLM/RAG. PKSHA Technology has strengths in natural language processing and image recognition.
