Sounds like you've entered a fun career path! Prior to working at HubSpot, I worked at a startup/scaleup and learned a ton about being scrappy.
I might need a bit more context on exactly what type of support you mean, but if I can read between the lines a bit, I'll do my best to provide a few tips. It sounds like you're doing two things... 1) creating content sales can use and 2) creating nurture email flows to support sales. So let me break that into two sections
Creating sales content:
- I'd recommend partnering with someone who is close to your product, but also understands the customer pains that the product solves. Either a product marketer or sales engineer.
- Set up a cadance that you'll meet with them going forward (maybe weekly to start getting things moving)
- Work with them to identify the top pain points customers are dealing with when they don't have your solution, and how your solution helps them solve those pains. This can be your first set of assets you create content around.
- I'd also recommend identifying 1-5 sales reps who are willing to be champions for marketing
- Meet with them regularly and find out what they need to support their selling -- is it a pitch deck? is it a one pager they can send out? talk tracks, snippets, etc?
- Prioritize quality over quantity. Sales might ask for everything, but prioritize and don't take on too much at once.
For email flows:
- I'd first start with some sort of MQL / SQL framework if you haven't already
- Then I'd identify a conversion path for prospects/buyers and figure out the best emails to trigger based on where they are in their buying journey
