about 222:

We’re an early stage startup working on building the future of social. We are not excited about a future where humans spend the majority of their day in a virtual world. By facilitating genuine human connections IRL, we're building a product that swings the pendulum in the other direction.

We’re building the world’s first IRL social prediction model - trained on hundreds of thousands of points of unique human to human interaction data.

We’re backed by a word-class set of investors including General Catalyst, Y Combinator (W23), Upfront Ventures, NEA, Jaegermeister, 1517 Fund, Cory Levy (Z Fellows), the Founder of Dropbox (Arash Ferdowsi), the Founder of On Deck (Julian Weisser) & more.

  • You’re passionate about solving the problem 222 is tackling and excited to use bot classic ML methods & LLMs to predict humans social behavior
  • You have experience fine tuning an LLM
  • You have experience working with and building ETL pipelines and preparing data for experimentation
  • You have experience with cold start recommender models
  • You're comfortable building ML/data infrastructure and pipelines for experimentation, training, and deployment
  • You have trained applied ML models that are used in production
  • You have a strong stance on the ethics surrounding user psychology in social products
  • Regardless of personal experience, you’re excited about wearing different hats across machine learning, data engineering, & architecture
  • Demonstrated history of building outside of work/school (projects/products, applications, music, art, etc.)

we’re looking for this type of person:

🖌️ experience building ML infrastructure & applying ML models to real world problems
