A real-time signal intelligence platform for GTM teams. Autumn tracks prospects across posts, commits, blogs, and announcements, surfacing buying signals the moment they appear. Define your ICP and the signals that matter, and get a live feed filtered by intent delivered to email or Slack.
Autumn has launched with real-time signal detection across social media, GitHub, blogs, and announcements. Features include custom ICP definition, intent-filtered feeds, and Slack/email notifications. The product is live with a self-serve onboarding experience for founders and GTM leaders.
Best friends since Columbia orientation with complementary backgrounds (VC sourcing tech and AI research). Self-serve onboarding suggests a product-led growth motion targeting the startup ecosystem before expanding to enterprise. Signal-based selling is a growing category with strong tailwinds from AI agent adoption.
<p>Real-time buying signal detection from unstructured digital sources to prioritize outbound sales outreach.</p>
The platform reads everything your prospects post, share, or build online and instantly tells your sales team who's ready to buy and why.
Autumn AI continuously ingests and processes unstructured data streams from social media posts, GitHub commits, blog publications, job postings, and company announcements using fine-tuned NLP models and LLM-based entity extraction. The system maps each detected event against user-defined Ideal Customer Profiles and scores signals for buying intent in real time. When a prospect triggers a high-confidence signal—such as publicly discussing a pain point the seller addresses, hiring for a relevant role, or open-sourcing a related project—the platform instantly delivers a contextualized alert via Slack or email with suggested outreach angles. This collapses the traditional research-to-outreach cycle from hours of manual work to seconds of automated intelligence delivery.
It's like having a thousand interns reading every tweet, blog post, and GitHub repo your prospects touch—except these interns never sleep, never miss a signal, and actually write useful summaries.
<p>Autonomous multi-agent system that builds comprehensive, continuously updated prospect dossiers without human intervention.</p>
AI agents automatically build and update a living research file on every prospect by crawling dozens of sources so your reps never have to Google anyone again.
Autumn AI deploys modular, autonomous AI agents that each specialize in a different data domain—one monitors social media activity, another tracks GitHub contributions, another parses company blogs and press releases, and others scan job boards and regulatory filings. These agents operate independently but share context through a central orchestration layer, collaboratively assembling a rich, multi-dimensional prospect profile that updates in real time. When one agent detects a relevant change (e.g., a prospect's company just posted three ML engineering roles), it triggers downstream agents to investigate correlated signals (e.g., recent funding announcement, new product launch). The result is a continuously enriched prospect dossier that gives sales reps instant, deep context for every conversation—without a single minute of manual research.
It's like having a team of private investigators who each watch a different part of your prospect's digital life and meet every morning to compare notes—except they meet every millisecond.
<p>ML-driven predictive scoring that dynamically ranks prospects against evolving Ideal Customer Profiles based on behavioral signals rather than static firmographics.</p>
Instead of guessing who fits your ideal customer profile based on company size and title, the AI watches what prospects actually do online and scores them on real behavior.
Traditional lead scoring relies on static firmographic attributes—company size, industry, job title—which poorly predict actual buying intent. Autumn AI's predictive ICP matching engine ingests the continuous stream of behavioral signals detected by its NLP and agent systems and feeds them into a machine learning model that learns which signal patterns historically correlate with conversion for each customer's specific ICP. The model dynamically re-weights signal importance as new data arrives: if prospects who star certain GitHub repos and post about specific pain points convert at 4x the rate of those who merely match firmographic criteria, the system automatically elevates those behavioral signals. The output is a real-time, ranked feed of prospects ordered by predicted conversion likelihood, with explainable signal attribution so reps understand exactly why each prospect is surfaced. Over time, the model refines itself using closed-loop feedback from CRM outcomes.
It's like a dating app that stops matching you based on height and job title and starts matching you based on who actually laughed at your jokes and swiped right on your hobbies.
