Nesto Inc. is a Montreal-headquartered Canadian digital mortgage lender and mortgage technology provider, founded in 2018 and licensed across Canadian jurisdictions. It sits on the financing side of the residential real estate value chain rather than the listings side — originating, underwriting, and servicing mortgages direct-to-consumer at nesto.ca, and, following its 2024 acquisition of CMLS Group, administering roughly CA$73 billion in residential and commercial mortgage assets. Its Nesto Cloud business (nestocloud.ca) sells the same origination, underwriting, and servicing platform to banks, credit unions, and commercial lenders as SaaS or fully outsourced BPO, and advertises "seamless API integrations with your existing systems and third-party providers" alongside a Maestro AI underwriting engine. That API surface is not publicly documented: there is no developer portal, no published reference, no OpenAPI or other machine-readable contract, and no self-serve signup. Access is a commercial engagement negotiated with the Nesto Cloud team. As a mortgage lender Nesto sits outside the listings syndication layer entirely — no RESO Web API or Data Dictionary certification, no RESO UPI usage, and no CREA Data Distribution Facility participation is published or discoverable. The company's only machine-readable public artifact is a security.txt whose disclosure scope explicitly names "Web applications, APIs, and customer-facing services", confirming APIs exist while none are documented for outside developers. Its compliance posture is, by contrast, published and audited — SOC 1 Type II, SOC 2 Type II and ISO 27001:2022 with a Vanta trust center — and its GitHub organization (nestoca) ships MIT-licensed developer-platform tooling such as the joy GitOps CLI, though no client SDK for any Nesto service.
