Simplify's Take

What believers are saying

  • Rav Singh Sandhu said in February 2026 Catapult smashed Stanford benchmarks internally.
  • The team says 2026 launch is coming, signaling active product momentum and urgency.
  • Hiring Founding AI Research Engineer and Senior Engineer roles suggests expansion before launch.

What critics are saying

  • Catapult still lacks a public 2026 launch, revenue proof, or customer-count disclosure.
  • LinkedIn and job posts show only a small founding team hiring in London.
  • Competitors like Notion, Slack, and Circle already own community workflows and user memory.

What makes Catapult unique

  • Catapult combines onboarding, profiles, and community operations in one workflow, reducing tool sprawl.
  • Rav Singh Sandhu said in 2025 Catapult pivoted after nine months of ideation.
  • The 2022 seed round from Blockchain Capital funded product development and early DAO integrations.
