The research part of Mento.vc's Startup Agent Benchmark: 960 tasks in six venture-analyst workflows (product and customer, market and why-now, competition, team, traction and risks, sourcing screens), with 80 synthetic and 80 real-world tasks in each. An agent answers each task in a fixed JSON schema using only two task-scoped MCP tools, search and fetch, over a frozen corpus that is mostly distractors, and may answer unknown; facts removed from the corpus earn credit only for unknown. A deterministic grader gives up to 80 points for answer content and 20 for cited evidence, minus a penalty for nonexistent citations, and the score is the mean over tasks under the answer keys corrected after the authors' audit (v0.7.1). Answering unknown everywhere scores 7.5.
