L2: New Customer Segments
Diagnostic question: Who else has the problem we already solve?
What innovation looks like: Finding adjacent buyers inside your existing market whose context is similar enough that your current product mostly works for them. Not rebuilding value. Improving how you reach, message, and onboard a slightly different buyer.
First experiment: Identify three companies or individuals who match a buyer profile adjacent to your ICP. Reach out directly. Ask them to describe their version of the problem you solve. Do not pitch. Listen for what is the same and what is different.
Watch out for: Assuming adjacent buyers need the same onboarding and messaging as your core ICP. They are close enough to reach, but different enough to misunderstand. Word of mouth travels within segments, not across them.
L4: New Distribution Channels
Diagnostic question: Where else could customers discover or access our value?
What innovation looks like: Turning product output into a distribution surface. Placing the product where buyers already spend time. Creating a free tier or embedded entry point that removes the signup barrier. The product does not change. The front door does.
First experiment: Identify one place where your product output is already being shared or seen by non-users. Map what a non-user sees when they encounter it. Ask whether that moment creates curiosity or stops there. Design one change to that moment that makes curiosity easier to act on.
Watch out for: Confusing marketing campaigns with distribution innovation. A campaign gets attention once. A distribution channel compounds. The test is whether the mechanism works without ongoing spend behind it.
L3: New Geographies
Diagnostic question: Where is demand already showing up that we do not yet serve well?
What innovation looks like: Studying how word of mouth actually travels in the target market before scaling anything. Building local trust signals: content, partners, language. Doing that before investing in paid growth. Pacing expansion to match local product-market fit signals, not a global launch calendar.
First experiment: Look at your current inbound data. Is there organic traffic, signups, or inquiries from a market you have not targeted? If yes, reach out to three of those users and ask why they found you and what they were hoping to get. That is your signal.
Watch out for: Assuming what worked at home works everywhere. Trust is built differently across markets. The product may translate. The growth loop almost never does without adaptation.
L5: New Products or Services
Diagnostic question: What adjacent jobs are customers already trying to solve around us?
What innovation looks like: Building something new that extends the core workflow customers already live in. Not a pivot, but an expansion. The new product retains existing customers by absorbing more of their workflow and attracts new buyers who need that job done.
First experiment: Ask five current customers what they do immediately before or after using your product to complete the job it helps with. Look for a consistent adjacent step they take with a different tool or manual process. That gap is your L5 hypothesis.
Watch out for: Building new before the core is strong. L5 requires more knowledge, more resources, and more risk than any other path. If you have not saturated L2 and L4 first, you are probably moving too early.
L2：新客户群体
诊断问题：还有哪些群体存在我们已经解决的问题？
创新方向：在现有市场中找到相邻买家，他们的场景与核心客户足够相似，当前产品基本适用于他们。无需重构价值，只需优化触达、沟通和引导这类略有差异的买家的方式。
首个实验：找出三个符合核心ICP（理想客户画像）相邻画像的公司或个人。直接联系他们，询问他们所面临的同类问题的具体情况。不要推销产品，只需倾听，找出相同点和不同点。
需注意的陷阱：假设相邻买家的引导流程和沟通话术与核心ICP完全相同。他们虽触达难度低，但差异足以导致误解。口碑在群体内部传播，而非跨群体传播。
L4：新分销渠道
诊断问题：客户还能通过哪些渠道发现或获取我们的价值？
创新方向：将产品输出转化为分销载体。把产品放在买家已花费时间的场景中。创建免费层级或嵌入式入口，消除注册壁垒。产品本身无需变更，只需调整“入口”。
首个实验：找出一个你的产品输出已被非用户分享或看到的场景。梳理非用户接触到产品时的所见内容。询问该场景是否能激发好奇心，或是仅停留在浏览层面。针对该场景设计一项调整，让用户更容易将好奇心转化为行动。
需注意的陷阱：将营销活动与分销渠道创新混淆。营销活动只能一次性吸引注意力，而分销渠道能持续产生复利效应。判断标准是该机制无需持续投入就能生效。
L3：新地域
诊断问题：哪些未被我们充分服务的市场已经显现出需求？
创新方向：在规模化前，先研究口碑在目标市场中的实际传播方式。构建本地信任信号：内容、合作伙伴、语言。在投入付费增长前完成这些工作。根据本地产品-市场匹配信号调整扩张节奏，而非遵循全球发布日程。
首个实验：查看当前的入站数据。是否有来自你未定向的市场的自然流量、注册或咨询？如果有，联系其中三位用户，询问他们为何找到你，以及他们期望获得什么。这就是你的信号。
需注意的陷阱：假设在本土有效的策略在所有市场都适用。不同市场的信任构建方式不同。产品可能可以本地化，但增长循环几乎都需要调整才能生效。
L5：新产品或服务
诊断问题：客户已经在尝试解决哪些与我们产品相关的相邻任务？
创新方向：构建新的产品或服务，拓展客户已在使用的核心工作流。这不是转型，而是扩展。新产品通过覆盖更多客户工作流来留存现有客户，并吸引需要完成该任务的新买家。
首个实验：询问五位当前客户，在使用你的产品完成相关任务前后，他们会立即做什么。找出他们使用其他工具或手动流程完成的一致相邻步骤。这个缺口就是你的L5假设。
需注意的陷阱：在核心业务稳固前就开发新产品。L5比其他任何路径都需要更多知识、资源和承担更高风险。如果尚未耗尽L2和L4的潜力，你可能行动过早。
