How do you maintain founder momentum without sacrificing your mental health, physical fitness, and operational clarity as you scale?
Don't let the new year pressure derail your momentum. In this episode of B2B Breakthrough, host Ciara Cristo chats with Kareem Raslan (https://uk.linkedin.com/in/kareem-raslan-d2c), co-founder of BrainGain (https://braingain.fit), about how product founders can enter 2026 with clarity, confidence, and operational strength. Learn how stripping away FOMO, conducting ruthless SKU audits, and focusing on unit economics can transform profitability. Whether you're battling burnout or chasing every opportunity, Kareem shares the exact framework BrainGain used to turn a 0% margin product into a 15% contributor—and why mental and physical health are just as critical as spreadsheets.
