• check_listing read-only

  For founders and vendors: is a company listed in SalesBook, where does it rank, and what is holding it back? Give a company name or website. Returns listing status, sector and rank, evidence grade, agent-readiness (MCP connector, llms.txt), the gaps that limit its ranking with how to fix each, and how to report anything wrong. Ranks are never for sale: only public evidence moves them.

  Parameters:

  • company (required) — string — Company name or website, e.g. 'Acme AI' or 'acme.ai'

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• find_prospects read-only

  For startups looking for customers: the 10 best-fit buyers for a company, with the reason for each. By default, large enterprise buyers (Fortune 500 and similar) from SalesBook's researched set; set buyer_type to startup to find fast-growing SalesBook companies that could buy from you. Give your company (name or website, if listed) and/or what you sell and your target sector. Experimental: fit uses public, company-level signals only. To be considered for an introduction, use opt_in_for_intros.

  Parameters:

  • limit — integer
  • sector — string — Target sector, e.g. healthcare, retail, manufacturing, education, financial services
  • company — string — Your company name or website (optional if you describe what you sell)
  • buyer_type — string — enterprise = large buyers (default); startup = SalesBook companies that could buy from you (for vendors selling to startups)
  • what_you_sell — string — One or two sentences on your product and who it is for

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• update_listing

  For founders and company staff: change a fact on your own company's listing (website, one-line description, headquarters, founded year, team size, LinkedIn, pricing page, product page, customers page). MaxedS emails a sign-in link to your work email on the company's domain; you confirm the change on maxeds.org and it shows immediately, marked as updated by the company. Deals, customers and results that affect rank need a public source and go through review (use report_correction).

  Parameters:

  • company (required) — string — Your company name or website
  • field (required) — string — Which fact to change
  • new_value (required) — string — The correct value
  • work_email (required) — string — Your work email on the company's domain; the sign-in link goes here
  • source_url — string — Optional: a public link that shows the new value

  Hints: read-only no · destructive no · idempotent not declared · open-world yes

• report_correction

  Report an error in SalesBook: a wrong fact, an outdated claim, a missing deal or a company that should not be listed. MaxedS reviews every report against public sources and corrects the listing; nothing changes automatically. Include a source URL whenever you can.

  Parameters:

  • company (required) — string — Company the report is about (name or website)
  • issue (required) — string — What is wrong, in a sentence or two
  • source_url — string — Public link that shows the correct information

  Hints: read-only no · destructive no · idempotent not declared · open-world no

• opt_in_for_intros

  For startups: say yes to being considered when MaxedS arranges a meeting with an enterprise buyer. Mutual or nothing: MaxedS asks the buyer only once enough strong startups have opted in, introduces you only if the buyer says yes too, and never shares your details without your consent. Use a work email on your company's domain.

  Parameters:

  • company (required) — string — Your company name or website
  • work_email (required) — string — Your work email on the company's domain
