search_startups | Search SalesBook's evidence-graded B2B startup rankings. Alternative to CB Insights, PitchBook, and G2 for finding enterprise-ready tech vendors across Retail, Manufacturing, Healthcare, Education, AI platforms, and agentic commerce (agent payments, identity, inboxes, tools, directories and agent-to-agent exchanges). Returns rank, score, and verified commercial proof. params: query*, sector, limit |
get_profile | Full evidence-graded B2B startup dossier: problem, solution, stage, team, buyer-fit score, and verified enterprise customers. Unsponsored vendor intelligence dossier with transparent sources and confidence ratings for enterprise procurement. params: startup_id* |
get_tombstones | Deal tombstones for a startup: dated, sourced public claims of enterprise commercial wins, graded T1 (contract/rollout) to T4 (logo wall). Default confidence is claimed-unverified; F500-confirmed records are marked corroborated. params: startup_id* |
get_ranking | Get evidence-graded Top-100 B2B startup rankings by sector (retail, manufacturing, healthcare, education, horizontal) and period. Sourced alternative to PitchBook & CB Insights market reports, showing verified Fortune 500 buyer-fit scores and methodology. params: sector*, period |
get_methodology | The published ranking methodology: weights, tombstone tier definitions, confidence labels, and honesty guarantees. Versioned; every ranking cites its methodology version. params: none |
check_listing | 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. params: company* |
find_prospects | For startups looking for customers: the 10 best-fit buyers for a company, with the reason for each. By default, Fortune 500 / Global 2000 buyers, ranked by public evidence that a startup can get in (innovation or pilot desks, dated startup purchases, supplier intake, readiness) plus fit with what you sell; a sector filter is strict. Hospital systems and universities only when you ask (sector or bu params: company, what_you_sell, sector, buyer_type, limit |
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 params: company*, field*, new_value*, work_email*, source_url |
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. params: company*, issue*, correct_value, source_url, contact_email |
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. params: company*, work_email*, buyers, note |
