Problem

GTM teams waste substantial time manually tracking prospects across a fragmented web of posts, tweets, commits, blogs, announcements, and other sources. The relevant buying signals are valuable but decay quickly: capturing them in real time requires monitoring dozens of sources per person, synthesizing unstructured information, and repeating the process across potentially thousands of prospects. Cold outbound therefore often reaches buyers at the wrong moment, wasting a sales rep’s best shot on an otherwise promising account.

The core use case is high-precision, signal-triggered outbound: identifying when a target prospect is hiring, raising capital, complaining about a competitor, searching for a solution, or otherwise showing intent, then prioritizing outreach while that context is fresh. Incorporation prospecting is a particularly clear example, where a sales or partnerships team can discover new startup founders and track early needs around banking, payroll, or infrastructure.

Product / Service

Autumn is a real-time signal-intelligence and AI sales platform. Customers define their ideal customer profile and the signals that matter; Autumn’s scouts monitor prospects across the internet, use long-context models to connect content with people and companies, and return a condensed feed filtered by intent rather than an undifferentiated firehose. Users can receive alerts through email or Slack when a target’s behavior matches a chosen signal.

The product is delivered as B2B SaaS and is designed to plug into an existing GTM stack through MCP, a REST API, and webhooks for automated outbound. Its benefit is to turn open-web research into a live operating layer for sales teams: reps spend less time researching, see prospects when they are more likely to be receptive, and can automate parts of prospect discovery and follow-up. A recent profile described pricing from roughly $375 per month.

Market

Autumn competes in sales intelligence, sales engagement, account intelligence, and the emerging category of real-time signal intelligence for GTM teams. Its differentiation is not simply contact data; it aims to continuously discover and interpret fresh behavioral signals from across the web. Adjacent competitors and alternatives include Apollo.io, ZoomInfo’s GTM Workspace, Seamless.AI, Instantly, LinkedIn Sales Navigator, Demandbase, and other intent-data and prospecting platforms such as Bombora.

The company is an early-stage YC Winter 2026 startup founded in 2025 and is listed as active. Its site says it is trusted by Brex, Corgi, and Mintlify, while a recent industry profile reported that it went from zero revenue during an earlier mid-pivot period to approximately $30,000 in monthly recurring revenue by the end of the batch; that would mean it is not best characterized as pre-revenue, though the figure is third-party reported. LinkedIn lists five employees, consistent with a small team still establishing traction in a crowded sales-intelligence market.
