Dustin — congrats on launching Critical Services Group. been working on outbound origination with B2B services investors and your fund has been on my radar. would be good to connect.
Dustin — though we share an IB/PE background (you at Elliott and 3G, me CS/Greenhill into growth equity), I've seen first-hand how challenging early proprietary origination can be. Been helping funds like Mentmore and Wingman with their outbound origination — curious what email infrastructure you're using these days — still mostly on shared IPs like Instantly, or have you moved to private/dedicated senders? Happy to share what's working best for similar mission-critical B2B services funds if useful. — Russ

Dustin — hope you're having a good Wednesday. wanted to reach out — congrats on launching CSG, always impressed by those who've taken the leap. though we share an IB/PE background, I hope to one day do the same. in the meantime I've been working on the origination side with funds like Backer Group and Mentmore — curious how you're thinking about origination at CSG. mostly proprietary or still seeing a lot through brokers? very best, Russell linkedin.com/in/russellt23
