A recent funding round is the clearest growth signal a startup sends. Connect https://api.leadocean.io/mcp first (setup is on the MCP page) and paste the prompt below.

The prompt

text
I sell to fast-growing US startups.
1. Call leadocean_list_enum_values for employee_range and job_level and use the exact strings.
2. Call leadocean_count_leads for C-Team people at companies with 11-50 or 51-200 employees that raised money in 2025 or later, in the US.
3. Tell me the count and every filter you used.
4. Do not call leadocean_search_leads until I say go.

Last funding year is the growth signal this prompt filters on. minLastFundingYear only matches companies with a funding year on file, so bootstrapped startups drop out.

Run it monthly. The dataset is refreshed monthly, so new rounds show up as the count moves. Each record also carries its own fetched_at date, so you can see how fresh a row is.

How many match

1,916 mailable people matched on 2 October 2026. Filters: jobLevel C-Team, employeeRange 11-50 or 51-200, minLastFundingYear 2025, country US.

Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. It is wider than a funding-type list: no round type is applied. leadocean_count_leads does not accept fundingType, so add a round such as Seed at search time to narrow the list.

What you get back

Search rows carry the fields below. These are placeholder values, not real records.

Variations

  • Replace "C-Team" with "VP, jobFunction Sales & Business Development" to reach the people who buy sales tools.
  • Change the funding year to 2024 and compare the count to see how many startups raised a year earlier.
  • Add "country GB" to size the same signal in the UK before choosing a market.

Records it spends

The enum lookups and the count are free. leadocean_search_leads costs 1 record per person returned, so a limit of 25 costs 25 records. Free gives you 1,000 records one-off with no card. Pro is $499 a month. See pricing.
