daydream is a platform that automates programmatic SEO, end-to-end. The platform helps businesses identify search patterns, creates content at scale, and automatically improves that content. We've raised $2.5M from leading investors like Basis Set Ventures, WndrCo, SOMA Capital and current and former Heads of Growth/Product Growth at companies like Notion, Airtable, Webflow and Dropbox. Our customers include Product Hunt, Notion, Tome and other venture-backed companies. We're on a high-growth trajectory and we're looking for people who want to join us on the journey to building a billion-dollar company. Our team previously worked together at Flixed, a startup we bootstrapped to $2M+ in revenue almost purely on the back of programmatic SEO.

GoodGoblin.ai is the ultimate "Admissions Operating System" designed to democratize elite college guidance. We believe expert mentorship shouldn't be a luxury for the few, so we built a data-driven platform that levels the playing field for every student. Our Four Pillars of Success Our platform guides students through the entire journey—from freshman strategy to senior year submission:   Architect (Grades 9–11): Builds a multi-year roadmap and identifies "profile gaps" early on.   Strategist (Grades 10–12): Uses data to find the perfect mix of "Reach," "Target," and "Safety" schools.   Editor (Grades 11–12): Provides 24/7 AI narrative coaching with instant feedback on clarity, story, and structure.   Analyst (Grade 12): Performs a final holistic audit to calculate real-time acceptance probabilities before you hit submit. Why It Matters Proven Results: Our users see a 31% boost in admission odds, with 97% of students securing a spot at a Top-30 university.   Radical Transparency: We show students exactly why an essay works using the same metrics admissions officers use.   Engineering Precision: We turn "guessing" into "optimizing" by analyzing millions of data points from successful applicants.   Join us in our mission to make the path to a dream university predictable, affordable, and stress-free for over 50,000 students worldwide.
