SaaS の創業者がテックスタックのシグナルを活用して最初の 100 人の B2B の顧客を見つける方法
創業者に優しい GTM の記事で、初期の SaaS チームがテクノロジ シグナルを活用して集中した最初の顧客リストを構築する方法を紹介しています。
Primary keyword: find first B2B customers
Also targets: SaaS lead generation, find SaaS customers, tech stack signals
Early SaaS founders do not need a massive database on day one. They need a small list of companies that are likely to care.
Technology stack signals are one of the fastest ways to build that first serious target account list.
Why broad outreach fails
A broad list like “all ecommerce companies” or “all startups” is hard to use.
It creates weak messaging:
“We help businesses grow.”
A technology-based list gives you a reason to reach out.
“I noticed your store uses Shopify and Klaviyo. We help Shopify brands improve email revenue.”
Step 1: Pick your best-fit technology
Ask:
-
What tools do my ideal customers already use?
-
What technology proves they have the problem I solve?
-
What tools integrate with my product?
-
What stack shows budget or maturity?
Step 2: Build a list of 100 accounts
Do not start with 10,000 leads.
Start with 100 companies that match:
-
One main technology
-
One customer type
-
One clear pain point
-
One outreach angle
Example SaaS ideas
| SaaS product | Target technology | Why it works |
|---|---|---|
| Shopify app | Shopify | Store already runs ecommerce |
| Email tool | Klaviyo/Mailchimp | Company cares about email |
| CRM enrichment | HubSpot | Company has lead workflows |
| Payment analytics | Stripe | Company processes payments |
| Website optimization | WordPress/Webflow | Website is core to acquisition |
Step 3: Write one specific message
Your first email should be simple:
-
Mention the technology
-
Explain the problem you solve
-
Ask a small question
Step 4: Learn from replies
The first 100 accounts are not only for sales. They help you learn:
-
Which segment replies
-
Which pain matters
-
Which technology signal is strongest
-
Which offer is unclear
Takeaway
To find your first 100 B2B customers, do not start broad. Use technology stack signals to build a focused list, test one message, and learn quickly.
