Paste one prompt into Claude with LeadOcean connected and get a sized list of ecommerce CTOs before you spend a single record. Connect the server at https://api.leadocean.io/mcp first. Setup is on the MCP page.
The prompt
Find CTOs at ecommerce brands worldwide.
1. Call leadocean_list_enum_values for industry and pick the online retail
and marketplace values.
2. Call leadocean_count_leads with title Chief Technology Officer and CTO,
jobLevel C-Team and those industries.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| title | Chief Technology Officer, CTO |
| jobLevel | C-Team |
| industry | Online and Mail Order Retail, Internet Marketplace Platforms |
Enum values are exact strings, which is why step 1 looks them up. LeadOcean has no single "ecommerce" industry, so the prompt uses these two.
How many match
271 mailable people matched on 2 October 2026. Filters: title Chief Technology Officer or CTO, jobLevel C-Team, industry Online and Mail Order Retail or Internet Marketplace Platforms, no country filter.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. It is narrower than the real market, because online sellers filed under a Retail industry label are not in it. Use the technology variation below for a wider net.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Chief Technology Officer | 51-200 | Online and Mail Order Retail | US |
| CTO | 11-50 | Online and Mail Order Retail | GB |
| Chief Technology Officer | 201-500 | Internet Marketplace Platforms | DE |
Variations
- Swap the industry line for "technologyCategories Ecommerce" to reach CTOs at sites running ecommerce software. That count was 2,217 mailable people on 2 October 2026, and it covers only the about 7.8M crawled sites with technology data.
- Add "country US" to keep the list to one market.
- Swap the title line for "VP Engineering, jobLevel VP" to reach the layer under the CTO.
