How to Find an Email From Product Hunt (2026)

TL;DR

• A Product Hunt launch gives you a product, a website and a maker name. Take the maker name and the product's company to LeadOcean and ask for the checked work email. Two calls.
• It takes about 15 minutes the first time, mostly getting a key. Each maker costs about 2 records of your 1,000 free ones: 1 for the search row, 1 for the email.
• For a list, loop the same two calls over a file of makers. The free plan allows 5 requests a second. Agency allows 200.

Prerequisites

• A LeadOcean account and key from app.leadocean.io. The free plan has no card and 1,000 records, one-off. Free keys get both the search and enrich scopes.
• The key in your shell as $LEADOCEAN_API_KEY.
• curl and jq. For the bulk step, a file with one name,company pair per line.

export LEADOCEAN_API_KEY="paste-your-key-here"

One rule first. Product Hunt has its own terms and a developer API with its own rules (Product Hunt terms, September 2026; API docs, October 2026). Read them before you scrape anything at volume, and write only to people you have a real reason to write to. The Product Hunt API 2.0 is a GraphQL interface with public, private and write scopes, so a list of launches is a query, not a scrape.

Step 1: Read the launch page

Open the launch and note three things: the product name, the website link and the makers listed. A maker's profile shows the name and what they chose to publish. Most do not publish an email, so treat a blank as a no.

Write down the company name as the product's own site states it. That is what you search on, not the Product Hunt tagline.

Product:  Acme Notes
Website:  acme.com
Maker:    Jane Doe
Role:     Founder

A launch is also a timing signal. Write while the launch is recent and your note can mention it.

Step 2: Find the maker in LeadOcean

Search on the name and the company. The body is flat JSON and every filter is an array. Each person returned costs 1 record, so keep limit small.

curl -s -X POST "https://api.leadocean.io/v1/people/search" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "content-type: application/json" \
  -d '{
    "q": "Jane Doe",
    "companyName": ["Acme Notes"],
    "limit": 3
  }' | jq -c '.data[] | {name: .profile_data.profile_full_name, person_id: .meta.source_ids.person_id}'

Read the rows before you pick one. Check the title and company against the launch page. The name sits at profile_data.profile_full_name in each row. If the name is common, add a title filter such as ["Founder"] or a country.

To size a role before you spend anything, send count=true as a query parameter with limit 1. On 21 October 2026, the free leadocean_count_leads MCP tool counted 1,018,109 mailable people at C-Team level with the title "Founder", out of 4,101,901 matching with or without an email. Mailable here means a verified, catch-all valid or catch-all address.

Step 3: Get the work email

Send the person_id to the work email endpoint. It returns one address at the person's current employer, or data: null.

curl -s -G "https://api.leadocean.io/v2/people/email/work" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  --data-urlencode "person_id=PERSON_ID_FROM_STEP_2" | jq

Only checked addresses come back: verified, catch_all_valid or catch_all. So null means "none that qualify", not "this person has no email". The call costs 1 record, found or not.

Do not guess jane@acme.com from a pattern. Guessed addresses bounce. LeadOcean gives no refund or credit-back for bounced emails, so read the status before you send.

Step 4: Run it over a list

Put one name,company pair per line in makers.csv. Loop both calls and write one JSON line per maker. The loop takes the first search row, so read a few results before you trust it.

while IFS=, read -r name company; do
  id=$(curl -s -X POST "https://api.leadocean.io/v1/people/search" \
    -H "x-api-key: $LEADOCEAN_API_KEY" \
    -H "content-type: application/json" \
    -d "{\"q\": \"$name\", \"companyName\": [\"$company\"], \"limit\": 1}" \
    | jq -r '.data[0].meta.source_ids.person_id // empty')
  [ -z "$id" ] && continue
  curl -s -G "https://api.leadocean.io/v2/people/email/work" \
    -H "x-api-key: $LEADOCEAN_API_KEY" \
    --data-urlencode "person_id=$id" \
  | jq -c --arg name "$name" '{name: $name, email: .data.email, status: .data.status}'
  sleep 0.5
done < makers.csv > results.jsonl

Each pass makes two calls, so the sleep keeps you under 5 requests a second on the free plan. Records add up fast: 500 makers spend up to 1,000. Run 20 first and read the hit rate before you spend on the rest.

When you want every founder in a segment and not a list of launches, skip the loop. POST /v1/exports takes search filters and writes a CSV, up to 50,000 rows a request and 500,000 a day. Bulk CSV export is not on the free plan. Solo at $97 a month includes it (pricing, October 2026). The app at app.leadocean.io has an Exports page with a filter builder and a price preview if you prefer clicks.

Then filter on status before you send. Keep verified and catch_all_valid. Treat catch_all as a risk you size, not a green light.

jq -c 'select(.email != null and (.status == "verified" or .status == "catch_all_valid"))' \
  results.jsonl > sendable.jsonl
wc -l sendable.jsonl

What you get

Both responses below are the response shape from the API reference. Every value is a placeholder, not a real record.

A search row carries the id you need at meta.source_ids.person_id. The profile fields sit under profile_data and are left out here.

{
  "success": true,
  "data": [
    {
      "profile_data": {},
      "meta": { "source_ids": { "person_id": "1234567890" } }
    }
  ],
  "meta": { "count": 1, "nextCursor": null }
}

The work email call returns success and data, with no meta object.

{
  "success": true,
  "data": {
    "email": "jane.doe@acme.com",
    "status": "verified",
    "verified_batch_date": "2026-09-20"
  }
}
