Hey Arinze — similar background, engineering into finance then PE. Been thinking a lot about proprietary origination in lower-mid industrials lately. Would be good to connect.
Hey Arinze, similar background — though I was doing European growth equity not acquiring industrial businesses like Stonebase. most lower-mid industrial funds I talk to are running on PitchBook or Grata, maybe Affinity, and then basically Excel and email for everything else on the origination side. but proprietary deal flow stays inconsistent. nothing connects systematically — the firm's thesis and network intelligence don't feed into each other, so origination never builds on itself. do you disagree? — Russ

hey Arinze — this kept rattling around. when I was doing growth equity we had every subscription going — PitchBook, CRM, enrichment tools, the lot — and I still spent half my time manually pulling origination together across all of it. always wondered if that was just us being disorganised or if it's genuinely universal. did you ever run into that at Stonebase, or was it just us? — Russ
hey Arinze — appreciate the connect either way. I'm in and around industrial origination all day — if you ever want to swap notes on what's working for lower-mid deal flow, I'm easy to find. — Russ

Hey Arinze, see we share a similar PE path, though I was in London doing growth equity not acquiring lower-mid industrials. the typical origination setup I see is a data subscription, a CRM that's half-populated, and a lot of Excel and Outlook doing the heavy lifting. yet the off-market pipeline stays weirdly thin. the intelligence is all there but it's scattered across tools and inboxes — so nothing compounds into a real origination edge. do you disagree?

Hey Arinze, something I keep coming back to with industrial funds. most funds I talk to are still 70-80% broker-dependent for deal flow. works fine until two funds get shown the same deal and it becomes a pricing war. the proprietary pipeline is the thing that's supposed to prevent that — but it rarely gets built systematically. curious whether Stonebase has cracked that or if it's the same pattern. Russell searchloop.ai linkedin.com/in/russellt23
hey Arinze — one more thought on this. at my old fund we had a solid stack and smart people, and origination still felt like it restarted from scratch every cycle. took me a while to realise it wasn't a people problem — the tools just didn't talk to each other. did you ever run into that at Stonebase, or was it just us?

hey Arinze — one thing I keep coming back to from my time doing growth equity — the funds with real proprietary pipelines aren't just seeing more deals. they're seeing them earlier. that changes everything downstream — pricing, competition, conviction. curious if you've been thinking about this at Stonebase.

hey Arinze — appreciate you reading these either way. always good to have more PE people in the network. I spend most of my time on origination infrastructure for funds, so if it's ever relevant, happy to compare notes. Russell searchloop.ai linkedin.com/in/russellt23
