Ditto on the 'ask'. If you don't ask them for benefits, equity, etc., you won't receive. Sit down with them and have a talk, or, better yet, simply sit down with them. Sounds like it's ripe time to hold a big ol' weekend of collaboration & BBQ somewhere warm that everyone can meet, greet and socialize a bit.

Getting to know the folks better face to face might make this an easier longterm decision. Once you know them better you may also get more solid ideas on how to approach them re: benefits / equity & such. "Waiting until we're profitable" is merely bullshit, just note :)
