Our Mission

Every child deserves consistent protection across every app and device

Parents shouldn't have to configure parental controls separately on Netflix, YouTube, TikTok, Roblox, and dozens more. Phosra is the infrastructure layer that makes “set it once, enforce everywhere” possible.

The problem

Children use an average of 7 different apps and platforms daily. Each has its own parental control system — different settings, different terminology, different enforcement levels. Most parents give up after configuring two or three.

The cost

A child with strict YouTube filters can still access unfiltered content on TikTok. A bedtime enforced on one device doesn't apply to another. Every platform gap is a protection gap — and children find them faster than parents can close them.

Our Approach

Define once, protect everywhere

Phosra is an open specification and infrastructure API for child safety. Parent-facing apps integrate once with the Phosra API to extend enforcement everywhere. Phosra translates and enforces policies across every connected platform — from streaming parental locks to DNS-level web filters to mobile device restrictions. One set of rules. Every platform. Always in sync.

Community Standards

The enforcement engine for the standards families follow

Phosra isn't just infrastructure — it's the technology that makes social pledges stick. When a family commits to “no smartphones before 8th grade,” Phosra is the enforcement layer that makes that commitment stick at the device level. When families adopt norms for phone-free childhood, Phosra translates those norms into verified, cross-platform protection.

Standards exist

Community standards like screen-free schools and delayed smartphone access set the bar for families — packaged rule sets based on research and shared values.

Families adopt

One click to adopt a community standard. Rules generate automatically based on the standard definition and your child’s age.

Phosra enforces

Standards push to every connected platform. Families earn verified badges. Schools see cohort adoption. Pledges become protection.

How It Works

Three steps to universal protection

Parents set rules

Through your app or the Phosra dashboard, parents define rules across all 45 policy categories — screen time limits, content ratings, web filters, and more — for each child.

Phosra connects

The Phosra API maps rules to platform-specific enforcement actions. One policy becomes Netflix parental controls, YouTube restricted mode, NextDNS filters, and more.

Enforced everywhere

Rules push to connected platforms automatically. Changes propagate in seconds. Parents see real-time enforcement status across every device and app.

Our Values

Built on principles, not compromises

Privacy First

AES-256-GCM encryption for all sensitive data. Zero-knowledge policy handling — we enforce rules without exposing child identities to platforms.

Universal Coverage

One API call enforces policies across DNS providers, streaming platforms, gaming services, device management, and browser extensions.

Compliance Built In

KOSA, COPPA 2.0, EU DSA, and 49 more child safety laws mapped to policy categories automatically. Stay compliant as regulations evolve.

Developer Friendly

REST API, MCP tool integration, webhooks, sandbox environments. Build child safety features in hours, not months.

Leadership

Built by parents who build platforms

Three companies founded and acquired. Five years of platform infrastructure at Mastercard. Now building the open spec for child safety.

Jake & Susannah Klinvex

CEO & Founders

Founded three companies, all acquired — including Personation (acquired by eMoney Advisor) which was then acquired by Fidelity, and LoyalTree (acquired by SessionM) which was then acquired by Mastercard. Jake spent five years at Mastercard working on technology partnerships and blockchain/digital assets strategy, then co-founded withSoul, an AI platform acquired by Gloo which IPO'd at the end of 2025 (GLOO). At Phosra, they are applying the infrastructure playbook from fintech to child safety — building the open spec that connects every parental control to every platform. Jake and Susannah are parents of five children — they built Phosra because they needed it themselves.
