Could you build this?
Partial An agent that opens PRs on a website is buildable with coding-agent tooling, but the claimed de-anonymization of visitors into companies depends on proprietary identity and firmographic data that vibe coding cannot produce.
What it would actually take: The core is an agent harness that runs code changes through git, CI, and A/B testing tooling, with analytics integrations. The hard part is de-anonymization: matching IP, cookie, and visitor signals to company records requires a large proprietary identity graph or paid data vendors. Reliable results also need growth-marketing and experimentation expertise to judge which automated changes actually help.
