description: 'May is a French digital-health company, operated by LN CARE SAS, whose mobile
  app supports future and new parents from fertility and pregnancy through the first years
  of a child''s life. It pairs a medical messaging service staffed by French-qualified
  midwives, pediatric nurses and doctors — answering questions seven days a week from 8am
  to 10pm — with an expert-reviewed content library, roughly hour-long audio masterclasses,
  everyday tracking tools for sleep, feeding and weight, and Mya, an in-app AI medical
  assistant. Founded in Paris in 2020 by Cécilia Creuzet, Antoine Creuzet and Adrien Brunet,
  it reported more than 400,000 users and a team of around 80 health professionals, raised
  €7M in September 2024 to expand into Spain and the United Kingdom, and also sells a
  parental-support benefit to employers. It was surfaced as a portfolio company of Serena
  and profiled in the API Evangelist network; it publishes a consumer marketing site, a blog
  and an Intercom help center, but no public developer program, no API reference and no
  machine-readable API contract of any kind.'

x-domain-note: >-
  may-sante.com (the URL Serena's portfolio profile lists) 301-redirects to
  https://www.may.app/, which is the canonical marketing host and the one every probe in
  this profile was run against. Both domains are the company's own. The legal operating
  entity is LN CARE SAS, 112 avenue de Paris, 94306 Vincennes, France (R.C.S. Créteil
  879 732 584); contact@may-sante.com.
x-source-classification-note: >-
  Serena's own portfolio profile tags May as `edtech` (with `healthtech` secondary), which
  is how the original stub arrived carrying an Edtech tag. The company's product is a
  regulated-adjacent consumer health service — medical messaging with qualified perinatal
  clinicians and health-data hosting on an HDS-certified host — so the tags here are set to
  digital health / parenting rather than education technology.

  note: >-
    Full STEP 0b contract-discovery pass run against every host: the canonical marketing host
    (www.may.app), the legacy brand domain (may-sante.com, which 301s to it), the two
    subdomains found in certificate-transparency logs (capig.may.app, go.may.app — neither
    resolves), and the guessed api./app./developer./docs. patterns (NXDOMAIN on may.app).
    Probed for REST OpenAPI/Swagger, GraphQL introspection, MCP tools/list, AsyncAPI and both
    A2A agent-card paths. No machine-readable contract of any kind exists, no first-party SDK
    exists on any registry, and there is no GitHub organization. The company was reclassified
    from the stub's Edtech tag to digital health / parenting.
x-coverage:
  state: none
  reason: no-developer-program
  detail: >-
    May is a direct-to-consumer mobile health app for parents — the whole public surface is a
    51-page WordPress marketing site in three locales plus a seven-collection Intercom help
    center whose only partner-facing section routes health professionals, press and
    partnerships to an email conversation, and the sole backend hostname in the company's
    public DNS (capig.may.app, found in certificate-transparency logs) is a dangling CNAME to
    a deleted AWS Kubernetes ingress load balancer in eu-west-3.
