Executive Summary

Job seekers and resume services are losing interviews to opaque ATS filters because many optimization tools either overfit to generic buzzwords or produce hallucinated keywords that don't match employer screening criteria; this pain affects roughly 150M active annual job seekers and the broader career-services ecosystem. Because automated screening increasingly removes candidates before human review, even small keyword mismatches translate to measurable lost opportunities and revenue. You could build a product that extracts only authentic, signal-bearing keywords from job postings (distinguishing required vs. preferred and contextual vs. boilerplate), maps them to a candidate’s resume, and outputs ATS-optimized rewrites plus pass-rate predictions. Delivered as a browser extension, API, and one-click resume editor, the focus would be on precision, explainability, and avoiding LLM hallucinations. The market looks attractive right now: approximately a $4.5B addressable market (150M job seekers × ~$30 average spend) with growing ATS use and clear user demand for fast, productized tools that demonstrate ROI. LLMs make sophisticated NLP feasible, but they also raise the bar for accuracy—so timing favors solutions that can prove real lift. This idea can differentiate by delivering measurable outcomes (A/B-tested pass-rate improvements), building a data moat of verified keyword-to-hire signals, and combining model outputs with rule-based validation for auditability. That said, competition is high and success will require partnerships, continuous validation against employer signals, and a clear go-to-market to convince users the tool truly reduces ATS rejections.
