What it does

SegmentStream is a marketing intelligence engine for teams and AI agents. Cross-channel attribution, incrementality insights, forecasting, and budget optimization — all in one platform. Powering $100M+ in ad spend for leading startups and enterprises including Synthesia, DerTour, Raylo, Eneco, and SimpliSafe.

SegmentStream provides AI-native infrastructure for marketing measurement. MCP tools that connect AI agents to attribution, campaign analytics, and marketing data — in real time.

Cross-channel attribution, incrementality testing, marginal analytics, automated budget allocation — the engine that finds where every dollar stops working. Ask any questions, generate custom reports, reallocate budgets, and more. Explore the most comprehensive attribution tech on the market. Stitch interactions across sessions, devices, browsers, and CRM into one customer journey — using both deterministic and probabilistic ID matching. Measure how ads actually contribute to revenue — beyond last-click, in-platform bias, and black-box methodologies. See projected conversions alongside observed — recent campaigns are measured on what they'll deliver, not just on what's already in. Stop…from segmentstream.com

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
