GTM engineering is COLLAPSING. I asked two competing founders.

Tim Scheuer co-founded Oxygen, Jai Toor co-founded Deepline. Between them they see what thousands of go-to-market teams actually buy, actually build, and actually abandon. I invited them on for a power hour with me, Spencer Tahil, for one hour, unscripted, no edits to the argument. What is in it: . Where the buy line sits in 2026, and why it moved . The two worlds: enough engineers in house, and everyone else . What flopped, and what quietly got adopted instead . Whether we have hit peak go-to-market engineering (we have not) . Why I think the title subdivides, and why Tim thinks it does the opposite . The five people on the planet who are the full unicorn everyone is hiring for . What two hundred dollars a month actually buys you now .

We think, build and enable, and own the motion until teams can. Field Notes is the series. One room, people who are actually building, no slides.
