Alkali

Executive Summary

Alkali is a pre-seed, YC-backed (S25) construction SaaS platform building AI-powered PDF viewing, takeoffs, and real-time collaboration for structural estimators and steel fabricators — a real niche that large incumbents like Bluebeam and PlanSwift have genuinely left underserved. The market opportunity is credible ($2.5–2.7B combined takeoff and estimating TAM, growing ~9–10% CAGR), and the structural steel element detection capability is the most defensible differentiator in the stack. However, traction is nearly impossible to verify — named customer logos are unconfirmable, financial metrics are entirely absent, and the team of two has no identifiable construction industry operating experience. The single biggest risk is that Bluebeam, Autodesk, or a better-funded AI-native rival closes the structural AI gap before Alkali can establish an entrenched customer base and proprietary training data moat.
