Company
https://autumnai.comAutumn is building the first real-time signal intelligence platform for GTM teams. We monitor posts, commits, blogs, and announcements, surfacing buying signals the moment they appear. Define your ICP and the signals that matter, and we deliver a condensed, real-time feed filtered by intents.
Verdict
Medium Signal
Market Opportunity
GTM signal intelligence is a real and growing B2B market with clear ICP (sales and marketing teams at high-velocity companies). Demand for intent data is established. The AI-native angle — proactive agents that act on signals autonomously — is a credible wedge into the broader category. TAM is meaningful but not uncrowded.

Founder Signal
Shiv Kampani (CTO) is a Columbia CS grad (Dec 2025, 4.07 GPA) with an AI Residency at SandboxAQ and a first-author paper accepted to the NeurIPS CaLM workshop on causal discovery. Vishnu Sampathkumar (CEO) also Columbia CS (2025), with ML internships at Modulus Labs and BrainSightAI, a stint at Sierra Ventures, and two research publications including an Arxiv paper on GNN-based Alzheimer diagnosis from 2021. Both are fresh grads with strong research pedigree but no industry product-shipping experience. They have worked together since university — good co-founder fit.

Competition
Apollo.io, 6sense, ZoomInfo, Bombora, Demandbase, and Clay all play in intent data and ICP-based prospecting. Autumn differentiates on real-time unstructured signal monitoring (posts, commits, blogs, filings) vs structured intent data, and on the MCP / AI-agent-native angle. That is a legitimate differentiated approach, but the incumbents are well-funded and expanding. Winning enterprise GTM buyers away from established platforms is a hard go-to-market challenge for two fresh grads.

Product
Publicly launched roughly one month ago and already fielding back-to-back demo calls per founders' own posts. Released an MCP that integrates with Claude Code for proactive GTM signal delivery. Early customers include fintechs and deep-tech companies. The website is sparse but the product is live — tracking signals across LinkedIn, X, GitHub, blogs, job postings, and filings. Traction is early but real.
OverallC Tier
Autumn AI is a stronger company than its D-tier suggested — the analysis failed because LinkedIn data was unavailable at the time. Both founders are sharp Columbia CS researchers with ML depth (NeurIPS paper, published research) and strong co-founder chemistry. The product is live, has early customers, and the MCP release targeting the Claude Code ecosystem shows product instinct. The core risk is competition: Apollo, 6sense, and Clay are formidable, and winning enterprise sales budgets as two fresh grads with no prior company-building experience is a hard problem. Worth watching — the AI-native GTM angle is real, but execution against incumbents will define whether this goes anywhere.
