Team-based map making with Felt

I ask because I've got ~200 acres of forest I use a drone to survey. I generate a high resolution orthophoto, and I currently built my own site on top of leaflet using tiles cut from the large orthophoto.

I'm working with conservation organizations to try and restore some stream habitat, and being able to markup maps together would be incredible, but it looks like you are focusing on vector layers first?

Is it possible to provide my own tile server url? (e.g. I'll host the tiles on S3/Cloudfront/whatever, I just want to fancy notation/collaboration infrastructure.)

Edit:

Follow up -- I'm just one person who happens to work with various conservation groups to maintain the health of my forest. Typically, these groups are already strapped for cash, but it looks like this wouldn't really fall under 'personal' use because it's multiple people collaborating on a map? Very curious about whether you plans include a price tier for "I guess I want something like this but I'm also just like, one dude and not a business"

Edit 2:

Looks like yes, I can bring my own baselayer. (In my case, I have two base layers, one topgraphic, and an additional one that's the raster image, but it looks like I could create a similar experience on Felt?) So really, then the question becomes one of pricing for small uses like mine.

Off topic, but I like how the site uses a green background, stands out in the sea of gray and black that most sites use

On the one hand they've nixed their PLG entry, on the other hand I'm not entirely clear what the use case and market size is for personal use here is anyway let alone multi-user personal use. Maybe Can or Sam can elaborate...
