Scrappy, rapid SaaS idea validation in a single day with zero budget
零预算⼀天内快速简易验证 SaaS 创意
Let’s be honest. Building a SaaS solo is tough. You’ve got a dozen ideas, zero
budget, and just enough caffeine to get through the night. But here’s the
thing most people don’t tell you: You don’t need to build anything to know if
your SaaS microniche idea is actually worth it.
说实话，独⾃打造⼀个 SaaS 产品很难。你有⼗⼏个想法，零预算，只有⾜
够的咖啡因⽀撑熬过夜晚。但⼤多数⼈没告诉你的是：你根本不需要构建任
何东⻄，就能知道你的 SaaS 微利细分市场创意是否真的有价值。
I learned this the hard way after wasting months building tools nobody
wanted. Now, I run every microniche SaaS idea through a ruthless, rapid
fire, one-day validation test — no code, no cash, no excuses. If it doesn’t
pass? I move on.2025/7/4 08:36

我是在浪费了⼏个⽉时间开发没⼈想要的⼯具后，才痛苦地学到这⼀点的。
现在，我会⽤⼀个⽆情、快速、⼀⽇完成的验证测试来检验每⼀个微细分市
场的 SaaS 创意——不写代码，不花钱，不找借⼝。如果它过不了关？我就放
弃。
In my last article about 7 Microniche Ideas I talked about possibilities, now
it is time to put them into practise. Let me walk you through the exact
scrappy process I use for quick SaaS idea validation. This is for the solo
founders, indie hackers, and anyone tired of guessing. I’ll show you how I
go from “Is this worth building?” to “Let’s build” (or “Forget it”) — all before
dinner.
在我上⼀篇关于 7 个微细分市场创意的⽂章中，我谈到了可能性，现在是时
候将它们付诸实践了。让我带你⾛过我⽤来快速验证 SaaS 创意的具体简陋
流程。这适合独⽴创始⼈、独⽴⿊客以及任何厌倦猜测的⼈。我会向你展示
我是如何从“这值得做吗？”到“开始做吧”（或者“算了”）——全部在晚饭前完
成。
1. Find a Real Microniche Pain (Not Just a “Nice-to-Have” Problem)
1. 找到⼀个真实的微细分市场痛点（⽽不仅仅是“可有可⽆”的问
题）
Most SaaS ideas fail because no one truly needs them. I used to chase broad
markets — “project management for everyone!” — and got lost in the noise.
Now, I hunt for hyper-specific microniche problems. Think:
⼤多数 SaaS 创意失败，是因为没⼈真正需要它们。我过去追逐的是⼴泛市
场——“⾯向所有⼈的项⽬管理！”——结果淹没在噪⾳中。现在，我专注于寻
找超具体的微细分市场问题。⽐如：
Time tracking just for freelance writers who bill per article
专为按⽂章计费的⾃由撰稿⼈设计的时间跟踪⼯具
Inventory tools made only for food trucks that travel weekly2025/7/4 08:36
⻚码# 4/25
专为每周巡回的餐⻋设计的库存管理⼯具
HR policy trackers for 10-person remote teams — nothing bigger
适⽤于 10 ⼈远程团队的⼈⼒资源政策跟踪器——不适⽤于更⼤团队
Forget “helping small businesses.” You want to solve a pain that keeps
someone up at night. One microniche group. One real headache.
别再想着“帮助⼩企业”了。你要解决的是让某个⼈彻夜难眠的痛点。⼀个微
⼩细分群体。⼀个真正的难题。
Focusing on a hyper-specific microniche unlocks true painkiller SaaS ideas
专注于超具体的微⼩细分市场，才能发现真正解决痛点的 SaaS 创意
Where I Find These Microniche SaaS Problems
我在哪⾥发现这些微⼩细分市场的 SaaS 问题
Here’s what works for me:2025/7/4 08:36
⻚码# 5/25
以下是对我有效的⽅法：
Lurking in niche Reddit threads (r/freelanceWriters, r/foodtrucks)
潜伏在细分领域的 Reddit 讨论区（如 r/freelanceWriters，
r/foodtrucks）
Reading complaints in Slack communities and private Discord servers
阅读 Slack 社区和私⼈ Discord 服务器中的抱怨
Watching people duct-tape ugly solutions together in Google Sheets
看着⼈们⽤ Google 表格拼凑丑陋的解决⽅案
And yes, talking. I DM people. I ask, “What’s the most annoying thing about
your job?” Sometimes they rant for 20 minutes. Sometimes they ghost me.
But the rants? That’s gold.
是的，还会聊天。我会私信别⼈，问：“你⼯作中最烦⼈的事情是什么？”有
时他们会抱怨 20 分钟，有时他们会不理我。但那些抱怨？那是宝贵的信
息。
Specific example: I once spotted a thread where food truck owners were
swapping hacks for tracking spoiled inventory. Paper logs, sticky notes,
WhatsApp groups. Not ideal. That’s a microniche pain, not just a want.
具体例⼦：我曾看到⼀个讨论串，⻝品⻋⽼板们在交换追踪变质库存的技
巧。纸质记录、便签、WhatsApp 群组。都不理想。这是⼀个微⼩细分市场
的痛点，⽽不仅仅是⼀个需求。
2. Build a No-Code Landing Page in 30 Minutes (Zero Budget SaaS
Validation)2025/7/4 08:36
⻚码# 6/25
2. 在 30 分钟内构建⼀个⽆代码着陆⻚（零预算 SaaS 验证）
You know what’s easier than building an app? Making a quick no-code
landing page. I use Carrd — it’s dead simple. Sometimes I’ll use Notion or
Google Sites if I’m lazy.
你知道⽐开发⼀个应⽤更简单的是什么吗？制作⼀个快速的⽆代码着陆⻚。
我⽤ Carrd——⾮常简单。有时候如果我懒的话，会⽤ Notion 或 Google
Sites。
Here’s what I put on the landing page:
这是我在着陆⻚上放的内容：
One clear headline (“Inventory tracking for roaming food trucks”)
⼀个明确的标题（“流动餐⻋的库存跟踪”）
A short, honest pitch (“Stop losing $$$ to spoiled ingredients. Get alerts
before stuff expires.”)
⼀个简短、诚实的推销语（“别再因变质⻝材亏钱了。过期前收到提
醒。”）
An email signup (“Want early access? Drop your email.”)
⼀个电⼦邮件注册（“想提前体验？留下你的邮箱。”）
That’s it. No fluff, no fake features. Sometimes I add a single question:
“Would you pay $9/month for this?” You’d be surprised how honest people
are when you ask directly.
就这些。没有废话，没有虚假功能。有时我会加⼀个问题：“你愿意为此⽀
付每⽉ 9 美元吗？”你会惊讶于⼈们在被直接问及时的诚实程度。
Connect it to Mailchimp or Mailerlite for simple email capture. No tech
skills required for this scrappy MVP validation.2025/7/4 08:36
⻚码# 7/25
将其连接到 Mailchimp 或 Mailerlite，轻松捕获电⼦邮件。这个简陋的 MVP
验证不需要任何技术技能。
Quickly create a no-code landing page that clearly communicates your SaaS value and captures
emails
快速创建⼀个⽆需编码的登录⻚⾯，清晰传达你的 SaaS 价值并收集电⼦邮件
3. Go Where Your Microniche Audience Hangs Out (Without
Spamming)
3. 去你的微细分市场受众常去的地⽅（不要发送垃圾信息）2025/7/4 08:36
⻚码# 8/25
Don’t just blast your landing page everywhere. I learned this the awkward
way. Instead:
不要到处乱发你的登录⻚⾯。我是通过尴尬的经历学到这⼀点的。相反：
Join a couple relevant subreddits or niche forums
加⼊⼏个相关的⼦版块（subreddit）或细分论坛
Read the room — see what people are actually struggling with in your
SaaS microniche
观察现场——了解⼈们在你的 SaaS 微利基市场中真正遇到的困难
Drop your landing page only if it fits the conversation (“Hey, I’m building
this for food trucks. Would love your thoughts.”)
只有当与你的对话内容相符时才发布你的登陆⻚⾯（“嘿，我正在为餐⻋
开发这个产品。很想听听你的看法。”）
I also send cold emails. Nothing fancy. Just:
我也会发送冷邮件。没什么花哨的。只是：
“Saw your post about inventory headaches. I’m testing a tool to help food
trucks avoid spoilage. Mind checking out this one-pager? Brutal feedback
welcome.”
“看到你关于库存头疼的帖⼦。我正在测试⼀个帮助餐⻋避免⻝物变质的⼯
具。介意看看这份⼀⻚纸介绍吗？欢迎坦率反馈。”
Some ignore me. Some reply with gold. Either way, these quick traction
signals are invaluable.
有些⼈忽视我，有些⼈回复的内容⾮常有价值。⽆论哪种⽅式，这些快速的
反馈信号都⾮常宝贵。2025/7/4 08:36
⻚码# 9/25
Engage authentically in niche communities and use targeted outreach to gather honest feedback
真诚地参与细分市场社区，并通过有针对性的外展活动收集真实反馈。
4. Ask Just One Simple Question (And Actually Listen)
4. 只问⼀个简单的问题（并且真正倾听）
Forget 20-question surveys. No one has time. I ask one key question to
validate SaaS microniche demand:
忘掉 20 个问题的调查问卷，没⼈有时间。我只问⼀个关键问题来验证 SaaS
细分市场的需求：
“Would you pay for this? If not, why?”
“你会为此付费吗？如果不会，为什么？”
Or sometimes, 或者有时，
“What’s the worst thing about your current solution?”
“你⽬前的解决⽅案最糟糕的地⽅是什么？”
I embed this as a one-question poll on the landing page, or ask directly in2025/7/4 08:36
⻚码# 10/25
emails. The goal? Get to the point. If people say “no,” I want to know why —
that feedback sharpens the validation.
我会把这个作为⼀个单问题投票嵌⼊到着陆⻚，或者直接在邮件中询问。⽬
标是什么？直击要点。如果⼈们说“不”，我想知道原因——这些反馈能让验
证更加精准。2025/7/4 08:36
⻚码# 11/25
5. Score It Fast — Then Decide: Build or Move On
5. 快速评分——然后决定：是构建还是放弃
I keep it simple for rapid SaaS microniche idea validation. After 24 hours, I
look at:
我保持简单，以便快速验证 SaaS 微利基想法。24 ⼩时后，我会查看：
How many emails did I get from my landing page?
我的登录⻚⾯收到了多少封邮件？
Did anyone say they’d pay? (Even just one “hell yes” beats 50 maybes)
有没有⼈表示愿意付费？（即使只有⼀个“绝对愿意”，也胜过 50 个可
能）
Did people mention their own workarounds or beg for features?
有⼈提到他们⾃⼰的解决⽅法或请求添加功能吗？
Was the landing page conversion above 5%? (Below 1% is a red flag)
着陆⻚转化率是否超过 5%？（低于 1%是⼀个危险信号）
Can I actually build this microniche SaaS in a month or less?
我能否在⼀个⽉内或更短时间内实际构建这个微利基 SaaS？
I use a quick scorecard for these rapid validation signals. If the signs aren’t
strong? I move on. No guilt, no sunk cost fallacy.
我使⽤⼀个快速评分卡来评估这些快速验证信号。如果信号不强烈？我就放
弃。没有负罪感，也没有沉没成本谬误。2025/7/4 08:36

My Favorite Example: When “No” Saved Me Months of Work
我最喜欢的例⼦：当“拒绝”帮我省下了⼏个⽉的⼯作
Last year, I nearly built a SaaS for remote HR teams to manage time-off
requests. Looked promising. I did my scrappy rapid-fire test — landing page,
Reddit, emails.
去年，我差点开发了⼀个供远程⼈⼒资源团队管理请假申请的 SaaS。看起
来很有前景。我做了快速简陋的测试——登录⻚、Reddit、邮件。
Guess what? Crickets. Two signups. Both said, “We just use Slack and Google
Sheets. Works fine.”
结果呢？鸦雀⽆声。只有两个注册⽤户。他们都说：“我们就⽤ Slack 和
Google 表格，挺好⽤的。”
That clear “no” stung, but it saved me months of unnecessary development.
I moved on and tried the next microniche pain point. Eventually, one of
these scrappy MVP tests led to my first paying SaaS customer.
那个明确的“拒绝”让我很受伤，但它帮我省下了⼏个⽉不必要的开发时间。
我转⽽尝试下⼀个微⼩细分市场的痛点。最终，其中⼀个简陋的 MVP 测试
带来了我的第⼀个付费 SaaS 客户。2025/7/4 08:36

Lessons I Wish I’d Known Sooner About Rapid SaaS Validation
我希望早点知道的关于快速 SaaS 验证的经验教训
Most SaaS ideas aren’t worth building — and that’s OK.
⼤多数 SaaS 创意不值得去做——这没关系。
You don’t need fancy tools. Carrd, Reddit, and a Gmail account are
enough.
你不需要花哨的⼯具。Carrd、Reddit 和⼀个 Gmail 账户就⾜够了。
People are brutally honest, especially when you ask for feedback on a
problem they truly experience.
⼈们⾮常坦诚，尤其是当你询问他们对⾃⼰真实经历的问题的反馈时。
The best validation is someone actually giving you their email — or
better, money.
最好的验证是有⼈真正给你他们的电⼦邮件——或者更好，给你钱。

虑代码和功能。
The real magic? You’ll stop guessing and start learning — fast validation
without budget. You won’t waste time building products nobody needs.

Final Thoughts on Rapid Microniche SaaS Idea Validation
关于快速验证微细分 SaaS 创意的最终思考
If I could go back, I’d tell my past self: Validation comes before code. Always.
Use your scrappy toolkit of no-code landing pages, Reddit research, and
direct outreach. Trust the traction signals, not your hunches. Move fast, fail
faster, and only build what customers actually ask for.如果可以回到过去，我会告诉过去的⾃⼰：验证总是在编码之前。永远如
此。利⽤你那套简陋的⼯具包——⽆代码着陆⻚、Reddit 调研和直接联系。
相信市场反馈信号，⽽不是你的直觉。⾏动要快，失败更快，只构建客户真
正需要的东⻄。
Give this scrappy mini MVP validation framework a shot. Your next SaaS
microniche idea might be just one day away from a genuine “yes” — or a
quick, painless no.
试试这个简陋的⼩型 MVP 验证框架。你的下⼀个 SaaS 细分市场创意可能只
需⼀天，就能得到真正的“是”——或者⼀个快速、⽆痛的否定。
And honestly? Either answer is a win.
说实话？⽆论哪种答案，都是⼀种胜利。
