Don’t Lose Your Momentum: How Product Founders Enter 2026 Strong

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.

Kareem Raslan is the co-founder of BrainGain, a direct-to-consumer home gym equipment company operating across the UK and Europe via Shopify and Amazon. What started as two friends selling dumbbells from their parents' garages during the pandemic has scaled to over 100,000 customers across 30 countries. With a background in restructuring and finance, Kareem brings a data-driven approach to e-commerce, focusing on unit economics, operational discipline, and sustainable growth. Beyond building BrainGain, Kareem now mentors emerging brands on scaling smartly and staying profitable in competitive markets.
