New products expose their rough edges in public. Founders share what they launched, what is missing, and what they plan to improve next.
Use product launch monitoring to find those posts, then keep only launches where your agency can point to a specific need.
SocialListeningAPI searches public posts on Hacker News, LinkedIn, and X and Google results for the phrases you choose. It returns normalized records with source URLs.
Step 1: Search for launch language
Create a SocialListeningAPI account and claim the 100 free credits. Choose launch phrases that fit your market:
Show HN analytics toolwe launched developer platformintroducing our new ecommerce appjust shipped AI workflowproduct launch fintech
Add a category word so the results match work your agency understands.
Step 2: Run product launch monitoring across four sources
Run a phrase across Hacker News, LinkedIn, X, and Google:
for endpoint in \
hackernews/search-posts \
linkedin/search-posts \
x/search-posts \
google/search
do
curl --get "https://api.sociallisteningapi.com/api/v1/$endpoint" \
--data-urlencode 'query=we launched developer platform' \
--header 'x-api-key: YOUR_API_KEY'
done
One phrase across four sources costs 5 credits. Results use data.items and keep the source URL.
The Hacker News API, LinkedIn search API, and
X search API pages explain each social source. Use the
Google endpoint docs for web results.
Step 3: Find a visible service need
Read the launch post and product page. Keep the launch when you can point to evidence such as:
- The founder asks for launch or positioning feedback.
- The site has unclear onboarding or missing product pages.
- The post mentions a redesign, migration, or growth experiment.
- The launch needs technical documentation or a demo.
Do not assume every new company needs an agency. Remove launches where your only reason is that the product is new.
Step 4: Create the weekly shortlist
Store product name, founder, launch date, source URLs, category, observed need, and review status in an external sheet or CRM. An external LLM can suggest a category, but a human must verify the product and service angle.
Use the launch URL as the duplicate key. Eight phrases across four sources cost up to 32 credits per weekly run.
Step 5: Send useful outreach
Mention the launch and one concrete observation. Offer a relevant idea or example before asking for
a call. Do not send a broad we help startups grow message.
Conclusion
Review ten launches in one category before expanding the search. Remove phrases that mostly return roundups or copies of the same announcement.
Only keep launches where your agency has something specific to offer. Record the source and the need you observed, because those two details should shape any outreach later.
