SoZo Chooses SELF to build a women's health companion, where users own and control their own data.

Privacy‑first health company chooses SELF's natural technology stack to give women true ownership of their health data, private AI companion, and care network

LONDON, 22 June, 2026 - SoZo is an integrative health solution that brings together a whole‑person private companion, sovereign digital relational support, and deeper in‑person connections into one continuous system. Launching with a focus on women's health first, SoZo today announced it has chosen SELF as the foundational technology partner for its hyper‑personalized and private, self‑sovereign health and wellbeing platform.

The partnership pairs SoZo’s whole‑person model of care with SELF's privacy‑by‑architecture technology. The combination is designed to deliver a system where women genuinely own their health narrative, their data, and their relationships, rather than renting access to them from a platform that monetizes their attention.

"SoZo" meaning to be whole, is built on a simple premise: that lasting wellbeing begins with personal sovereignty and self awareness. Its companion, first built for women, learns and adapts across her mental, physical, emotional, and relational health. Because she owns her data, she shares more honestly, making the support far more personal, including community support. That compounding loop only works if privacy and ownership are guaranteed by the technology itself, not promised in a marketing claim.

That requirement is what led SoZo to SELF.

Why SELF

According to a March 2026 KFF Tracking Poll, more than three‑quarters of adults (77%) are concerned about the privacy of the personal medical information they share with AI tools, even as roughly one in three now turn to AI for health advice. SoZo argues that trust deficit is untenable in a category that only works when people are honest, and people are only honest when transparency and privacy are non‑negotiable. Most digital health tools sit on extractive infrastructure: centralized servers, opaque data flows, and AI models trained on the very users they claim to serve. SELF is built on the opposite pattern, what it calls natural technology: systems modeled on living ecosystems, where intelligence and trust are distributed rather than concentrated, and where privacy is a default of the design rather than a premium feature.

For SoZo, that translates into concrete guarantees: 

● Data and AI sovereignty. Users own their lifelong health narrative and data. Women stay with SoZo by choice, not lock‑in.

● Private by architecture. Health memories, conversations, and derived insights are encrypted at rest with per‑user keys and protected in transit. SELF operates the infrastructure but, by design and operating policy, does not have routine access to user data.

● AI that doesn't feed on you. Language‑model inference runs on a ring‑fenced, self‑hosted instance under SoZo's own AI profile, using ephemeral per‑turn context. There is no cross‑user training, no model fine‑tuned on user data, and no data sale, ever.

● European‑resident, self‑owned infrastructure. The platform runs end‑to‑end on SELF's own European stack, removing the third‑party subprocessor sprawl that complicates privacy and compliance for most health apps.

● A sovereign "constellation," not a tenant on someone else's cloud. SELF Chain's constellation architecture lets SoZo run on a dedicated chain with its own economics, governance, and privacy boundaries, built on a shared, verifiable foundation. SoZo owns its narrative and its users' trust; SELF supplies the underlying technology under contract.

● AI that isn’t extractive on natural resources. SELF Chain’s constellation architecture uses no more energy than your cell phone. It doesn’t rely on the large scale data centers that are depleting our natural resources at alarming rates.

Underpinning all of this is SELF Chain, an AI‑native blockchain that implements Proof‑of‑AI consensus and a browser‑based full‑node model in which every participant's browser can build, vote, and verify as an equal node, with cryptographic keys that never leave the device. SELF's architecture also incorporates hybrid post‑quantum cryptography, designed for a longer horizon than most of today's health platforms contemplate.

A signal to the wider market

SoZo is the first health company to build on SELF's architecture, but both companies expect it to be a template. Across health, finance, energy, and education, a growing number of organizations need a genuinely privacy‑based, self‑sovereignty‑enabled technology provider, not another hosting vendor wrapped in "decentralized" language. SELF is positioning itself as the partner for companies that want privacy and ownership enforced by design rather than promised in a policy.

We looked hard at what 'private' and 'sovereign' actually mean once you get past the landing pages," said Vamshi Lingampally, Co-founder of SoZo. "With most providers, the privacy is a policy you have to trust. With SELF, it's enforced by the architecture; users hold the keys, the AI never trains on them, and nobody, including us, can quietly mine their most intimate data. For a companion built first for women, and for everything they're asked to carry and rarely get to talk about openly, that is not a feature. It is the whole foundation.”

“Health is the most personal data a human being has, and it should never become someone else's industrial asset," said Jonathan MacDonald, founder of SELF. "SoZo understood that instinctively, which is why this partnership matters. We built SELF so that companies don't have to choose between building something genuinely caring and building something genuinely private. To any organization weighing that same trade‑off: you no longer have to make it.

“We want millions of women to feel safe enough to take control of their health and wellbeing," added Lingampally. "SELF lets us promise them something almost no one else in digital health can: what they share stays theirs, for life. Deeply multi-dimensional support that knows them and stays with them. This, we believe, is non-negotiable for transforming our relationship with health, health systems and creating thriving communities.” 

Availability

SoZo's initial platform is being delivered on SELF's infrastructure ahead of an early‑adopter beta, with a first‑phase focus on women's health and later expansion across women's and men’s health needs including chronic conditions and addiction recovery. Further details on availability and partner programs will be announced by SoZo.
