I can go for that, as long as the research proposals are actually about math research.

The stuff in Airtable seems to be. The lion's share of what's there is research that has applications to, like, sensors and robotics and AI, even if the abstracts themselves don't state that, likely because the PIs behind those proposals aren't aware of those applications of their work.

(Just to illustrate how mathematicians can sometimes embody the archetype of Hans Guck-in-die-Luft: I had someone tell me once that there were no applications of ODEs or PDEs to the sciences or engineering.)
