In today's conversation, Carly sits down with SONNI co-founders Eliana Field-Marsham and Megan Black, who share the journey they took to start the SPF brand. Eliana and Megan share how bad sunburns and a family member's melanoma scare plus a frantic business-school text between each other led them to starting SONNI. They also unpack the realities of founder life, why 24/7 grind isn't effective, and how they navigate leading a company together with clear, clean division.
We also discuss:
- The health scares that led to SONNI being created
- Why "You can't be everything to everybody" in CPG
- Why daily SPF was a product experience problem, not an awareness issue
- Fundraising, bootstrapping, and when founders should pay themselves
- The case against the 24/7 founder grind
