Ghana has roughly 77 licensed veterinarians for a population of over 35 million. Andrews Mintah didn't learn that from a market report. He learned the shape of the problem from Ella, a close friend whose aunt's family had just landed in Ghana with their dog and needed something as unremarkable as a routine checkup. They didn't know which clinic was real, who to trust, or how to pay locally. They called around and got nowhere.
That ordinary failure, not an emergency, just a normal vet visit nobody could figure out how to book, became the starting point for Vetwoop, an AI-triage and clinic-booking platform Mintah co-founded with Leadson Apeesi and Julius Osman, all three students at Central University and the University of Ghana, building remotely with no office yet. Vetwoop is one of eleven finalists heading into the live pitch stage of the 2026 Moolre Startup Cup.
A Problem With Two Sides, Neither of Them Served.
When a pet gets sick in Ghana, Mintah says, the owner is usually alone with it. There's no quick way to gauge whether a symptom is serious, no reliable way to find a legitimate clinic, and no guarantee a new clinic will have access to records still sitting on paper somewhere else. Payment is typically cash or a personal Mobile Money transfer, tracked by hand if it's tracked at all. Every visit starts from zero. For expats, returning diaspora, or travelers passing through with a pet, the same problem compounds: they don't know the local clinics, the local payment norms, or who to trust in an unfamiliar place.
On the other side, independent vets and small clinics rely on walk-ins, lose revenue to no-shows, and have no way to build a reputation beyond word of mouth. Mintah traces the gap to two structural reasons. Global pet-care apps like PetDesk or Vetster were built around credit cards and US and European clinic networks, and simply never arrived here. And the genuinely hard part was never the app, it's the payments-and-payouts layer, collecting from an owner and automatically settling with a clinic, in a market where digital trust toward informal service providers is still being built.
What Vetwoop Actually Does
A pet owner opens the app and describes a symptom, "my dog hasn't eaten in two days and is vomiting," and Julean, Vetwoop's AI, assesses in seconds whether the situation is urgent, worth booking now, or safe to monitor. If booking is warranted, the owner finds a verified clinic nearby, pays by USSD or Mobile Money through Moolre, and gets an SMS confirmation while the clinic is paid out automatically. Every visit, vaccination, prescription, and lab result is saved permanently to the pet's record, and if the owner later moves or travels, that history and the same clinic-discovery flow travel with them.
The hardest technical problem was making a single payment atomically trigger a payout without ever losing track of money. When Moolre's webhook confirms an owner has paid, Vetwoop has to block replay attacks with Redis, flip the payment status, calculate the clinic's share after its own fee, validate the recipient's name before sending anything, call Moolre's transfer API, handle success, pending, or failed outcomes, retry on failure, and log every step, six Moolre endpoints functioning as one transaction. "Get any single step wrong," Mintah says, "and real money goes missing."
The first version treated collection and payout as two separate steps, collect now, sweep and pay clinics later, which left a window where a payment was confirmed but the clinic hadn't been paid. The team rebuilt so the payout fires directly inside the webhook handler, with a single table tracking every transfer's state and automatic retries.
The Moolre Layer
Vetwoop runs six Moolre endpoints in production: a payment link generator for USSD or Mobile Money checkout across MTN, Telecel, and AirtelTigo; a transfer endpoint to auto-pay the clinic's share; a status endpoint to check collections and transfers; a validate endpoint to confirm a recipient's name before any transfer goes out; a data endpoint for supported banks; and the SMS API for confirmations. The integration clicked, Mintah says, once the team realized collections and disbursements share the same account and authentication, letting them treat "owner pays" and "clinic gets paid" as a single flow instead of two separate vendor integrations. Without Moolre, Paystack could cover most of the core flow, but the team would lose native Mobile Money wallet disbursements and recipient name validation, and would still need a second provider for messaging. The one addition they'd want: an HMAC signature header on Moolre's webhooks, to cryptographically confirm a webhook actually came from Moolre before it touches Vetwoop's payment state.
Trust, Not Technology, Is the Bottleneck
The most surprising thing the team has learned isn't about adoption, it's about what's actually stopping it. They assumed the barrier would be digital literacy; instead, people already use Mobile Money constantly. The real hesitation is trusting that a clinic found through an app is legitimate, and trusting that money sent through the platform actually reaches the vet, which is why a verified-clinic badge and an auditable, automatic payout became more central to the product than originally planned. "The tech," Mintah says, "is the easy 20 percent."
The moment closest to derailing the project wasn't technical at all. It was Apple's App Store review process, a long list of requirements for a health app using AI, from privacy manifests to medical disclaimers, that felt endless as each fix surfaced a new rule. What kept the team moving was Osman working through the checklist methodically, and a steady trickle of users messaging to ask when the app would finally be available.
What's Next
Mintah is betting on animal health as an underserved corner of African tech. Human healthtech has gotten crowded, he argues, while pet ownership keeps rising in African cities with almost no digital infrastructure behind it. The team's stated ambition is for Vetwoop's model, verified local clinics, native Mobile Money payouts, portable pet records, to hold up not just in Ghana but for pet owners moving between African cities as travel and migration patterns shift.
Vetwoop pitches live in the final stage of the Moolre Startup Cup, with winners announced at the Grand Finale on August 29, 2026.
