YCbench

A live benchmark dataset for forecasting startup outperformance in Y Combinator batches.

This dataset was introduced in the paper: ["YC Bench: a Live Benchmark for Forecasting Startup Outperformance in Y Combinator Batches"](https://huggingface.co/papers/2604.02378) by Mostapha Benhenda.

Dataset Overview

YCbench provides structured public signals for Y Combinator startups (focused on the W26 batch of 196 companies). It enables rapid evaluation of models that predict which startups will outperform their batch peers in the short term (until Demo Day).

Performance is measured using a Pre-Demo Day Score that combines traction signals and web visibility.

Available Configurations

Quick Load

python
from datasets import load_dataset

# Load specific parts
startups = load_dataset("benstaf/ycbench", "startups")
scores   = load_dataset("benstaf/ycbench", "scores")
mentions = load_dataset("benstaf/ycbench", "mentions")

Or with pandas (simple way):

import pandas as pd
df = pd.read_csv("hf://datasets/benstaf/ycbench/yc_w26_pre_demo_scores.csv")
