The story behind the name
Together
Where animals find friends.
Born in Dutch, built worldwide, now in 19 languages from day one.
Pet care is fragmented across five apps, vet software is built for desktops, and owners have no single place to manage their pet's life.
The average owner uses five separate tools (social, vet booking, missing-pet posts, symptom search, shopping) that don't talk to each other.
Legacy vet PIMS (ezyVet, Provet, IDEXX Neo) charge $200+ per seat per month and were built for desktops, not mobile-native vets.
No system links an owner's pet history with the vets and services around them, so the relationship that matters most is the one nobody owns.
Most people walk away from a distressed stray because reporting is too hard. The founding insight that started Dierend.
Vet-software companies spend $400+ on cold sales to land a single clinic. We make clinics come to us, because we already have their customers in the app.
Free consumer tools acquire pet owners at near-zero cost: the same owners every clinic and shop is trying to reach.
Clinics and shops subscribe to reach owners already active near them. Consumer-led distribution, not cold outbound.
Bookings and payouts run on us; cross-side network effects deepen with every owner and clinic added.
Dierend is consumer-led vertical SaaS for the pet economy: acquire owners free, monetize through the businesses that serve them.
Owners, vets, and pet businesses share the same network. One platform, three sides of the pet economy.
Social feed and stories. AI symptom scans. Mate matching (playdate requests to other owners' pets). Missing-pet map. Universal reporting. Vet booking, video consults, and a store.
Clinic dashboard, patient records, appointment booking, video consults (rolling out), in-app chat with owners, and Stripe payouts. Standalone or alongside a multi-service business.
Storefront for products and services. Order management, customer messaging, and bookings. Groomers, sitters, and shops get a back-office without the desktop tax.
A real, shipped app: 50 screens across owner, vet and business modes, in 19 languages.





Free consumer tools acquire pet owners at almost zero cost. We route them into a vertical booking SaaS for vet clinics and pet shops, then retain both sides on a subscription model.
The AI health scanner (free monthly scans) and emergency reporting (50 free reports/mo) seed the community. Free missing & found pet ads then expand it, neighbourhood by neighbourhood, no ad spend required to be useful.
Every scan, report and alert routes the owner to the nearest vet clinic or pet shop in our network. Bookings and orders run in-app: vertical SaaS for the business, marketplace commission for us.
Owners stay for multi-pet history, deeper AI and priority routing; clinics and shops stay on per-seat subscriptions. Recurring revenue on both sides, and every paying business gives owners one more reason to stay.
No cold start: the free consumer tools are useful with zero clinics on board, so owners come first. We then sign clinics into demand that already exists in their neighbourhood.
More owners → more clinics and shops join → more reasons for owners to stay. The loop compounds, and customer-acquisition cost trends toward zero.
Missing-pet map seeded one metro at a time — Miami first. Every report recruits its neighbourhood; every shared AI scan is an ad. Channels measured against pre-committed kill/scale thresholds in the first 90 days (D30, K-factor, CAC per channel).
10 free design partners (months 1–3) → billing on from month 4 → founder-led sales in Miami/Florida → dedicated sales lead from month 10 expanding to NY/LA/TX. Owners pull their own vets in — product-led inbound grows with the user base at zero sales cost.
Consumer app is global from day 1 (19 languages, organic). Monetized B2B expands in gated rings: US → Canada (2028) → UK + EU (2028–29) → worldwide. Each ring opens only after the previous one passes retention and CAC gates.
Why this sequencing wins: clinics are never sold into empty demand — owner density always arrives first, and every market opening is sales + compliance work, never product work. The localization is already done.
No phone trees. No broken city hotlines. Any user, owner or passer-by, can report any animal in need from the street. The report routes to the correct responder automatically.
Take a photo. Frontier AI assigns a severity score and triage priority in seconds.
Precise GPS attached automatically. Pin-drop on the map for adjustment if needed.
Routes to the right NGO, vet, or city hall by location, with a PDF case file.
Free for every user (50 reports a month), so it spreads on its own: a zero-cost acquisition hook. And every report becomes a data point in the mortality map no other pet app collects.
A free triage assistant in every owner's pocket, with 3 scans a month at no cost. It's our cheapest acquisition channel and the top-of-funnel for the vet network.
Frontier-model providers (OpenAI on the free tier, Anthropic Claude for paid) sit behind our own routing layer, swappable and never locked in.
Pre-launch, but the full platform is built and deployed. The seed funds go-to-market, not core engineering.
Firebase Auth, Firestore, Storage and Cloud Functions v2 in production across 25 services.
Stripe and Stripe Connect: per-seat subscriptions plus marketplace split, 3 to 5% take.
Cost-tiered LLM routing on Cloud Functions: efficient models free, premium models for paid.
Mobile app built, store launch imminent, web app next. Built solo and AI-augmented, for exceptional capital efficiency.
Upside scenario at full viral performance — not historical results.
Base case we commit to (month 18): ~130k MAU · ~150 paying clinics · ~$465k ARR run-rate. Both live in one model — flip a cell to see either.
Per-seat monthly subscriptions for clinics and businesses, billed via Stripe. Fee-inclusive pricing.
$25–$50 / seat / month
Take rate on vet bookings, video consults, and store orders. Settled via Stripe Connect.
3–5 % take rate
Multi-pet AI scan history, deeper analytics, priority vet routing, ad-free.
from $5.99 / month
All lines are fed by the free consumer loop at near-zero CAC — plus a fourth: clinic-routed marketplace attach, as clinics push bookings and refills through the platform. Stripe + Stripe Connect already integrated.
Clinics expand, not just renew: seats grow ~1.5 → 2.4 and attach revenue compounds — net revenue retention > 100%.
Prices shown in USD; billed in each app store's local currency.
Blended CAC under $1 per acquired active owner (gross adds, churn replacement included) — every missing-pet alert and shared scan recruits the next user.
$39.99/seat (escalating at renewal, capped $49.99) at ~90% margin. Clinic LTV grows $3.6k → $8k+ via seat expansion, attach and churn maturing 4% → 1.3%.
3 to 5% take on vet bookings, video consults and store orders, settled via Stripe Connect, on top of subscriptions.
Fully-loaded clinic CAC (incl. sales payroll) $0.8–1.2k vs cohort LTV $3.6k→$9.7k; marketing-only CAC $120–730. Every driver is a cell in the 60-month model — data room.
Each incumbent owns one slice. None acquires owners for free and sells that demand to clinics, and none has the cross-side network effects.

MVP built · admin dashboard live · Stripe + Cloud Functions deployed
App launch (global, 19 languages) + $1.75M pre-seed close · US go-to-market from Miami · first design-partner clinics
~$4.5M seed (month 18, at proven metrics) · ~150 paying US clinics → expansion rings open: Canada → UK → EU
EBITDA-positive by mid-2030 on two rounds · ~$5.5M ARR run-rate in Year 5 · Series A optional, from strength
The vision
Every pet's lifetime health record, and every owner, vet and business on one network. We start with free AI care and become the layer the entire pet economy runs on.
Team (lean six, part-time-first) 47% · Marketing & UA 25% · Infra, AI & legal 7% · Contingency 6% · Unspent reserve 15%
~130k MAU · ~150 paying US clinics · ~$39k MRR (~$465k run-rate) · LTV:CAC crossing 3:1 · cash buffer intact
$1.75M pre-seed now → ~$4.5M seed at month 18 → EBITDA-positive month 46 on those two alone. A ~$10M Series A in year 3 is a choice, not oxygen — pro-rata the whole way.
Every path survives: seed late → ~12-month bridge in the buffer · seed never → 3-person core, profitable ~month 23. Financing decides the company's size, not its survival.
