01 How it works

From one sentence to a draft you approve.

One sentence becomes a reviewed plan. Big Fish reads, checks and scores. You make every decision that matters.

Your words

AI companies in Europe that are hiring evaluation engineers

Plan ready for your review
Example · step 1 of 6

Say who you want to reach, in one sentence.

02 Why Big Fish

Claims are cheap. Evidence isn’t.

Most prospecting tools guess, then write the guess down as fact. Big Fish only keeps what it can show you on the page.

“They’re scaling fast. Perfect time to reach out!”

A claim on its ownCan’t be checked. Big Fish leaves it out.

  1. 1

    Every claim keeps its source

    A signal is stored with the exact sentence, the page it came from and when it was read. If the quote isn’t on the page, the signal is discarded.

  2. 2

    Uncertainty is labelled

    Weak, stale and disputed evidence is marked. When sources disagree, the fact stays out of outreach until you decide.

  3. 3

    Scores show their working

    Fit is split into criteria you can read and reweight. Missing data is listed as missing, never guessed.

03 Account intelligence

Every account, with its working shown.

Each company arrives with its evidence, the page every quote came from, a fit score you can read, and one recommended next step.

04 Approval-first outreach

Approval is not sending.

Big Fish drafts. You edit and approve. Sending is a separate step that needs your own mailbox and your confirmation of the exact message, and it is off by default.

  1. Draft
  2. Approved
  3. Sent

Six ML hires, one evaluation backlog

Edit freely. Nothing leaves Big Fish while it is a draft.

05 Integrations

Built on public sources and free tiers.

Big Fish runs these services for you on the platform. You don’t bring API keys; you only connect your own mailbox, if you want to send.

  • Research

    Where facts come from. Free and public.

    • Company websites
    • Greenhouse, Lever and Ashby job boards
    • GitHub and arXiv
    • Tavily web search, for finding new companies

  • AI analysis

    Reads the stored pages and writes drafts. Always labelled as AI.

    • Google Gemini, free tier, by default
    • Anthropic Claude, optional and off unless enabled

  • Communication

    Only if you want to send approved emails yourself.

    • Gmail, your own mailbox
    • Google Calendar, read-only
    • LinkedIn messages are copied, never automated

Big Fish uses these services through their public APIs. Listing them doesn’t mean a partnership or endorsement. What is available depends on how the platform is configured, and a service is shown as connected only after a live test passes.
