Surge AI

39 mentions across 2 sources · 47% positive — mixed (weighted across 2 sources)

Hacker News, Lemmy

What users praise

  • • Expert workforce of doctors, lawyers and engineers differentiates it from open-call crowd annotators
  • • Benchmark catalog — GDP.xlsx, sudo L7, HANDBOOK.md — gets genuine technical engagement on Hacker News
  • • Openly grouped with Mercor, Scale AI and Turing as a serious frontier-lab supplier
  • • Runs like the Kimi K2.7 post-training show measurable agentic-coding gains with cited deltas

What frustrates them

  • • Almost no first-hand user accounts of the product itself in the scraped data
  • • Benchmark sponsorship and independence draw pointed skepticism from HN commenters
  • • Pricing is contact-only with zero public reference points for contract size
  • • Discussed as a vendor category, not a tool — hard to evaluate without a pilot
