Imagine you're an analyst in the ECM group advising a high-growth SaaS company that's looking to go public in the next 6-9 months. Market sentiment is generally positive, but the sector is very competitive, and some recent comparable IPOs have underperformed post-listing. Walk me through how you would develop the IPO pricing strategy and execute the bookbuilding process to maximize the company's valuation and ensure a successful offering.

你是一家投资银行ECM部门的分析师。你的客户是一家快速成长的SaaS公司，计划在未来6-9个月内进行首次公开募股（IPO）。目前市场情绪积极，但该行业竞争激烈，且近期有类似公司IPO后表现不及预期。请你阐述在当前市场环境下，你将如何为这家SaaS公司制定IPO发行定价策略和实施有效的簿记建档（Bookbuilding）流程，以最大化公司估值并确保发行成功。
