# The GTM Engineering Company > We build revenue infrastructure inside the CRM a company already owns — data > enrichment, account scoring, signal-based outbound, lead generation and > attribution — and hand over the runbook that keeps it running. Fractional GTM > engineering for B2B technology companies, led by founder Jorge Macias. Posts under `/blog/` are also available as markdown by appending `?md` to the URL — the blog is served by Framer, which does that automatically, and the markdown comes back through the main domain unchanged.
