Hi, always glad to see a founder ready for growth!

Co-founders are important but only for the right reasons.
You shouldn't bring a person on as a co-founder just because you can't afford to pay a hefty salary.
_________________________
A co-founder hire should strengthen the existing team long-term by:
1. Adding a depth of experience in a specific skill set
2. Working cohesively with the existing team (learn this by hiring the person for a trial 1 to 3 month period)
3. Having worked with successful companies

As for persuading someone to work with you for free... ah, you'll get what you pay for and that is not the unicorn you're hoping to on-board.

Consider talking to incubator and accelerator founders for recommendations for broad categories.

I specialize in accelerating brand growth. I am willing to discuss working with you to develop the foundation for your business growth as an experienced advisor. I can assist or lead in the vetting and hiring of an excellent candidate (also an area where I am experienced).

Finally, I work with many top venture partners and their core preference is to invest in strong teama with deep experience. Book me for a half hour to get started.
