Framer hits $2B, Webflow heads to Boston, and your codebase needs a DESIGN.md

Framer↗ raised $100 million. Series D, led by Meritech and Atomico, at a $2 billion valuation. The company is past $50M ARR and on track to double that this year, and 40% of the most recent YC batch launched on Framer↗ — the kind of detail that concentrates investor attention. The round came two months after Figma↗'s IPO, where shares surged 250% on debut, and the timing matters: investors are treating the design-to-web stack as a real category now, not a niche. Framer↗'s pitch is that it owns the full publishing lifecycle: design, CMS, analytics, A/B testing, enterprise auth. The funding goes to US expansion and AI.

Webflow Conf starts tomorrow in Boston (September 1-3, also online). The keynote is where the big announcements tend to land, specifically around App Gen, their AI-powered widget builder, which they've publicly said will gain auth, database integrations, and third-party API connections. That would move App Gen from "useful for simple interactive things" to "actually build web apps without writing the backend." Component Gen, which generates reusable UI from natural language, has been in beta since last year and seems likely for a broader release. The AEO push will probably get more airtime — Webflow has positioned itself as an "agentic marketing platform" since acquiring Vidoso, and the conference tends to be where they put a stake in the ground.

DESIGN.md is a thing now. A plain-text markdown file in your repo root that tells AI coding agents how your product should look: colors, typography, spacing, anti-patterns. Google Labs released a formal spec with a CLI validator in April. Vercel's DESIGN.md is already 6,500 words and includes a section headed "Reject generated-design reflexes." There's a library of 562+ ready-to-use files at designmd.app. The problem it's solving is real: AI agents that write frontend code have absorbed a generic aesthetic from the public web, and every generated UI drifts toward the same defaults unless you explicitly say otherwise. A repo-root DESIGN.md is how you push back on that.

Webflow Conf announcements land tomorrow. We'll cover anything worth covering.
