Your brand isn't training data.

We are entrusted with your most sensitive commercial assets. Our commitments below are explicit and architecturally enforced.

Zero-training guarantee

Beachside does not permit customer data — brand assets, prompts, uploaded references, or generated outputs — to be used to train, tune, or improve TheSEA or third-party provider models under our production provider configurations and agreements.

Strict tenant isolation

Every workspace runs under role-based access control with per-organization data boundaries. Your brand assets, prompts, and outputs are accessible only to authorized members. Tenant isolation is enforced at the application and infrastructure layers.

Your content, your IP

You retain rights to the brand assets you upload. Rights to generated outputs are defined in your customer agreement

How we build with AI.
What we promise.

Foundation models

Safety by design

Human in the loop

AI Act alignment

Beachside integrates approved third-party foundation-model providers through secure provider APIs, plus selected self-hosted models for specialized image processing. A full inventory with exact production providers, model names, versions, and use cases is available to enterprise customers under NDA.

We favor structured, UI-driven workflows that reduce the surface area for prompt injection and unsafe inputs. Outputs are governed by provider safety controls, internal review, and enterprise release validation.

Every AI feature ships with defined intended use and explicit limitations. Our team manually reviews and benchmarks generated outputs as part of release validation.

Beachside is designed to support applicable EU AI Act transparency expectations, including user-facing AI disclosure, model/provider inventory, intended-use documentation, and Instructions for Use for enterprise customers where applicable.
