Why Founders Choose 5 Foundations

Why Founders Choose 5 Foundations

Equity: Program is advisory — you keep ownership. Top performers may be considered for investment.

Efficiency: 5 Foundations cost 80% less than full-time hire per sprint.

Speed: We do in weeks what would normally takes months or years — because experience can fast-track success.

Who should Apply?

Founders & CEOs of early scale-ups with meaningful traction (From as early as $10K MR or clear route to it) who need investor visibility and execution capacity but can't hire expensive full-time operators but you too mature to sit in an accelerator.

What are the 5 Foundations?

Our program is built on five powerful foundations—each designed to give you the same edge as hypergrowth, investment-backed companies, while keeping ownership in your hands.

Foundation 1 : Hero Framework

Based on 17 years of experience working inside and alongside world-class product companies, like Fiverr and Google, the Hero Framework™ helps you move from product-market fit to hypergrowth.

Developed by founder, Sagi Shrieber—the first design hire at Fiverr, founder of a startup acquired by Similarweb, and later Design Director at Similarweb—this framework identifies your users’ deepest desires and emotional triggers. From there, we help you craft designs, messaging, and product experiences that resonate and convert.

At its core is Design Triggers, a neuropsychology-based UI design system inspired by the methods of top Silicon Valley companies. This approach uses the science of decision-making to drive emotional engagement, adoption, and growth.
