A Field-tested Guide To Underwrite Product And Tech Risk Into IC-ready Plans.
The Software Product and Technology Due Diligence Playbook is a focused, practitioner-oriented guide for investors and deal teams evaluating software businesses. It provides a clear framework for assessing product strength, technical architecture, scalability, security, engineering capability, and roadmap credibility—while translating technical findings into investment-relevant risks, costs, and value-creation opportunities. Designed for real-world deal timelines, it helps teams scope and execute a disciplined P&TD workstream in just a few weeks.
Blending strategic and technical perspectives, the Playbook covers everything from product-market fit and retention mechanics to codebase health, cloud posture, AI claims, and integration readiness. With structured checklists, risk registers, and IC-ready deliverables, it equips teams to separate signal from noise, avoid common diligence blind spots, and make confident, well-informed investment decisions.
