Simplify's Take

What believers are saying

  • Tilde announced an $8M seed in July 2025, extending runway for research.
  • The 2024 Sieve results showed interpretability can directly improve downstream performance.
  • Open roles for ML Engineer, Researcher, and Kernel Engineer indicate active productization in 2026.

What critics are saying

  • OpenAI, Anthropic, and Google can bundle interpretability features into their own platforms by 2026.
  • Tilde's single-digit headcount makes one failed model bet or hiring miss immediately damaging.
  • If customers prefer cheaper prompting tools, Tilde's control-product thesis loses its commercial edge.

What makes Tilde Research unique

  • Tilde Research pairs mechanistic interpretability with control products, not pure safety papers.
  • Its Sieve work used SAEs to improve Benchify code generation with 99.9% precision.
  • Khosla Ventures backed Tilde's $8M seed, signaling credibility among frontier AI investors.
