The fund that sits
downstream of
the standard

Threshold Fund I is a $100M investment vehicle built on a non-profit foundation that holds the Bathroom Health OS certification mark. The foundation cannot be acquired. Modelled on IKEA, Novo Nordisk, and the Wellcome Trust — the entity that holds the most valuable asset sits upstream of everything, and the fund operates under license.

The Problem

Why the opportunity
isn't being captured

The technology exists. Consumer trust in the hardware is unmatched. And yet the opportunity is stalled — because of a structural problem, not a technology problem.

Problem 01
The best technology is stranded without capital
The companies with the deepest domain expertise need $10–100M to scale. Hardware partners won't write that cheque to a single external company. Traditional VCs don't understand the hardware-health interface. The gap is structural, not technical.
Problem 02
The hardware anchor won't own the stack
TOTO has unmatched hardware distribution, brand trust, and the customer relationship — but their culture won't support a $10–100M single-company bet. They need ecosystem upside without ownership or operational risk.
Problem 03
Standard venture doesn't fund ecosystem infrastructure
VCs fund companies. But the bathroom health ecosystem needs clinical validation studies, consumer behaviour research, regulatory pathway work, and orchestration infrastructure. None of that fits a term sheet. So it goes unfunded, and the companies that need it can't succeed.
Problem 04
No one can hold the standard in permanent trust
Every platform eventually monetises the trust it was given — because commercial ownership structures make it inevitable. There is no existing vehicle that can hold the certification standard and consumer data in genuine, permanent stewardship. Until now.

"The entity that holds the most valuable asset cannot be acquired. That is the structural guarantee everything else depends on."

The Architecture

The foundation is
upstream of everything

Modelled on IKEA, Novo Nordisk, and the Wellcome Trust: the entity that holds the most valuable asset — the standard, the IP, the trust — sits at the top of the structure and can never be sold or captured by commercial interests below it.

Chorus Foundation
501(c)(3) or equivalent · Independent board · Cannot be acquired
Core Asset
BHOS Certification Standard
The mark, the standard, the six certification domains. Owned permanently by the foundation. Cannot be transferred, sold, or degraded by any commercial party.
Core Asset
Consumer Data Trust
Consumer health data held in stewardship — not by a commercial entity, but by a foundation whose charter prohibits extraction. The data belongs to the people who generated it.
Core Asset
Living Lab Network
Global accredited pilot sites. The evidence base, research infrastructure, and clinical validation that makes the certification mark credible to health systems and regulators.

Startup Equity
Invests in BHOS-certified companies across the health signal stack. Certification is the quality filter. By the time a company reaches the fund, it's been independently validated.
Orchestration Capital
Funds the platform infrastructure — APIs, signal aggregation, developer tooling — that no single portfolio company would fund alone but all of them depend on.
Commercial Facilitation
Connects certified companies to TOTO and other hardware partners. Takes a facilitation fee on commercial agreements — aligned with ecosystem success, not data extraction.

This architecture has
deep precedent

IKEA / Ingka + Inter IKEA
Brand in foundation · Operations below
The IKEA concept, brand, and franchise system are held in foundations that cannot be acquired. Every store licenses the concept from Inter IKEA. The commercial operations can change; the concept is permanent.
Threshold maps directly: BHOS standard in the foundation, the fund licenses it and operates below.
Novo Nordisk Foundation
Foundation owns investment arm owns pharma
A Danish charitable foundation owns Novo Holdings, which holds controlling stakes in Novo Nordisk and Novozymes. Commercial returns fund the mission. The foundation can never be acquired.
Threshold is structurally similar but the fund is independent rather than owned by the foundation — cleaner LP economics.
Wellcome Trust
Charitable foundation + investment portfolio
A £35B charitable foundation that invests commercially — including VC and private equity — to generate returns that fund scientific research. One of the world's largest health research funders.
Threshold's systems investing model (research + companies + policy) is closest to Wellcome in ambition, with a specific hardware anchor IKEA didn't have.
The Foundation — bathroomhealthos.com
Consumer data stewardship, the BHOS standard, and the certification pathway all live on the foundation's own site.
The Chorus Foundation independently holds the BHOS certification mark. Consumer health data is held in trust — not by a commercial entity, not by the fund, not by TOTO. The foundation cannot be acquired. That independence is what makes this fund's investment thesis credible.

The Franchise Model

How value flows
through the structure

The IKEA franchise model applied to health data: every certified company pays a fee to the foundation for the right to use the standard. That fee funds the mission. The commercial ecosystem's success directly underwrites the trust layer's independence.

Chorus Foundation
Sets and holds the BHOS standard. Accredits living labs. Stewards consumer data. Commissions clinical research. Publishes transparency reports. Grants certified partners the right to carry the BHOS mark — in exchange for annual certification fees and compliance with data governance rules.
Foundation → Fund
Licenses the BHOS standard and mark to Threshold Fund as an investment quality filter. The fund can only invest in BHOS-certified companies. This means the fund's commercial interests run directly toward protecting foundation independence: if the mark loses credibility, the fund's entire investment thesis collapses.
Threshold Fund
Invests in certified companies, funds orchestration infrastructure, and facilitates commercial agreements between portfolio companies and TOTO. Takes standard equity economics and commercial facilitation fees. Provides operating support to the foundation in early years, transitioning to self-sustaining foundation finances as certification revenue scales.
Fund → Partners
Connects certified companies to TOTO's hardware distribution and brand. Portfolio companies gain a commercial channel they could never access independently. TOTO gains first right of refusal on commercial agreements with the best companies in the ecosystem — without owning or operating any of them.
Ecosystem Partners
Pay annual certification fees to the foundation for the right to carry the BHOS mark. The mark opens health system, insurer, and institutional channels that are otherwise inaccessible to early-stage health-tech companies. Fees scale with the mark's credibility — which scales with the foundation's independence.
Partners → Foundation
Certification fees flow back to the foundation, funding the research, governance, and consumer trust infrastructure that makes the mark valuable in the first place. This is the franchise loop: commercial success funds the mission layer; the mission layer's integrity is what creates the commercial success.

Capital Allocation

Where the
money goes

The foundation is self-funding through certification fees, membership, and research grants — with bridge support from the fund in early years. The fund deploys $100M across five categories, all of which strengthen the foundation's position and compound the ecosystem's value.

Chorus Foundation — Revenue
Vendor Certification FeesPrimary
$20–50k per certified vendor per year. 20+ certified companies by 2030 = $400k–$1M annually. Grows as the BHOS mark becomes the industry standard.
Living Lab MembershipSecondary
Accredited sites pay membership in exchange for research access and co-authorship rights on published studies.
Research GrantsVariable
Academic and government grants for clinical validation. NIH, AMED (Japan), MRFF (Australia), university partners.
Fund Bridge SupportYears 1–3
Fund management fee subsidises foundation operations while certification revenue scales. Designed to phase out by year 4.
Threshold Fund I — $100M
Startup Equity40%
~$40M across 8–12 BHOS-certified companies: gut health, urinary monitoring, acoustic diagnostics, UTI detection, GLP-1 tracking, and 3–4 from the ecosystem audit.
Deep Research20%
~$20M via Chorus Foundation: clinical validation studies, peer-reviewed publications, IRB protocols, living lab infrastructure. The evidence base no single company funds alone.
Consumer Insights15%
~$15M on trust research, adoption studies, behaviour change frameworks. The hardest problem isn't technology — it's what makes people consent.
Orchestration15%
~$15M on the BHOS Developer Platform, signal aggregation layer, and intelligence infrastructure connecting certified vendors into a coherent consumer experience.
Policy & Capital Sourcing10%
~$10M on FDA/PMDA regulatory pathway work, insurer engagement, and building the LP pipeline for Fund II before Fund I is fully deployed.

Partners & LPs

Who belongs
in this ecosystem

Each party has a distinct role across the two entities. Mission alignment is the selection criterion — which makes LP conversations structurally simpler than a standard venture fundraise.

Anchor LP + Observer
TOTO
Hardware anchor, unmatched brand trust, 2027 commercial revenue goal. $10M buys preferred commercial rights to portfolio companies — not ownership of the ecosystem. Non-voting observer on the foundation board.
$10M · Fund LP
+ Foundation observer seat
Strategic LP + Foundation Member
Aged Care Operators
Fund LPs gain preferred pilot site status and early commercial access. Foundation members gain research access and co-authorship. Their residents are the living lab; their capital validates the consumer thesis to every subsequent LP.
$5M each · Fund LP
+ Foundation living lab members
Thematic LP
Longevity & Healthspan Funds
The bathroom is the most under-invested touchpoint in aging-in-place. The foundation's clinical credibility and data stewardship model creates a consumer trust moat that no standalone health-tech fund can replicate.
$20–30M · Fund LP
Fund only
Geographic LP
Japanese Institutional
TOTO is a Japanese company. The PMDA regulatory pathway is a priority. Japanese institutional capital has a clear reason to back an ecosystem elevating a Japanese anchor company's global health platform ambitions.
$15–20M · Fund LP

Research LP + Foundation Partner
University Endowments
Academic LPs gain co-authorship on foundation research, data access for independent study, and a graduate placement pipeline. UC Berkeley/CITRIS precedent already exists in the ecosystem.
$10–15M · Fund LP

Values LP
Wellness Family Offices
Patient, mission-aligned capital. The foundation model — holding data in trust rather than extracting it — resonates with family offices that have watched data extraction plays fail on trust. The two-entity structure is the proof point.

Path to Launch

Next steps

Seven steps, sequenced to front-load the structural decisions. The legal architecture comes first — everything else depends on it. First close target: Q4 2026.

01
Resolve the Chorus entity structure
Confirm whether Chorus is the foundation or whether a new entity needs to be incorporated. Establish the governance charter — the legal separation of foundation from fund is the first and most load-bearing decision. Engage a specialist in non-profit / fund hybrid structures.
Legal counsel · This month
02
Draft the Data Stewardship Charter
The foundation's governance commitment needs to be a formal, public document before any LP conversation starts. It is the foundation's most valuable asset and the answer to every sovereignty concern in the ecosystem. Engage a health data governance specialist.
Fordcastle + specialist · Q2 2026
03
Formalise the BHOS licensing agreement
Draft the agreement under which Threshold Fund licenses the BHOS standard from the Chorus Foundation. This document is the structural heart of the IKEA model — it defines what the fund can and cannot do with the mark, and enshrines the foundation's governance supremacy.
Legal counsel · Q2 2026
04
Soft-sound TOTO on the architecture
$10M into a fund with a non-profit foundation holding the standard is more culturally comfortable than $10–100M into a single company. The IKEA comparison is a useful frame for Japanese institutional stakeholders: a structure designed to protect the mission permanently, not extract from it.
Stephen + TOTO senior leadership · Q2 2026
05
Engage anchor technology partners
The data stewardship model directly answers every technology partner's sovereignty concern. Present the anchor tenant offer: equity investment, hardware partner as commercial channel, standard-setter status for their domain — with the foundation's independence as the structural guarantee that no commercial player can capture the layer above them.
Fordcastle · Q2 2026
06
Seed the foundation with its first members
Aged care operators as founding living lab members. Their participation is operational and symbolic — the evidence that the foundation model works before the fund asks LPs for capital. First certification fee revenue, however modest, is proof of the franchise loop.
Fordcastle + POC team · Q2–Q3 2026
07
Target first close at $30–40M
TOTO ($10M) + 2 aged care operators ($5M each) + 1 longevity fund ($15M). Use POC 001 results and first certified foundation members as the evidence base. First close signals the structure is real and unlocks portfolio deployment.
