Hepi Tech designs, builds and runs transaction platforms, digital wallets and integrations for organisations that can’t afford to get money movement wrong. Fifteen years of telecom-grade engineering. High-volume platforms in production. Zero tolerance for a lost transaction.
We focus on the parts of your stack where correctness isn’t optional — where every ledger entry, every wallet balance, every reconciliation batch has to be right.
End-user and agent wallets with balance management, transaction journals, double-entry accounting, dispute handling, and reconciliation against external processors.
Direct integration with Mobile Money operators, telco billing, SMS/USSD gateways, and carrier-grade transaction layers. Built on 15 years inside telecom systems.
Native Android & iOS apps, USSD/SMS menus, and Android POS terminal software. One transaction backbone, every channel customers actually use.
Advanced dashboards built on Grafana and Elasticsearch — real-time transaction monitoring, reconciliation health, business KPIs, and alerting for operations teams.
Role-based administration consoles for channels, users, agents, products, and operational workflows. Built so your team can run the business without calling engineering.
Infrastructure design, deployment and long-term operations. Remote-first and across time zones, from Geneva to West Africa.
The brief we keep solving: an institution needs to move value between end-users, agents, and external payment rails — reliably, auditably, across every channel its customers actually use.
We build the full stack: a core ledger with double-entry accounting and wallet balances, integrations with Mobile Money operators for top-ups and payouts, channel-specific front-ends (app, USSD, SMS, POS), and a backoffice where operations can investigate, reconcile, and act.
The same architecture that powers a national-scale distribution network — with customer wallets, agent wallets and POS-based retail — applies directly to digital banking, micro-insurance, agent banking, social transfers, and any system where accounts, transactions, and multi-channel access are the foundation.
Hepi Tech is a Swiss engineering firm based in Geneva, founded in 2023 by a senior systems engineer with fifteen years inside telecom and payment systems integration — the world where uptime is measured in nines and every message has to be accounted for.
We work senior-to-senior and remote-first: you deal directly with the engineer who designs and builds your system. No account managers, no hand-offs. For larger scopes, we bring in vetted specialists around the project.
Today we help run high-volume mobile money platforms in West Africa. Our engineering background spans telecom operators, banks, insurers and public institutions, and that is where we are headed next: organisations that need a partner who understands both the engineering and the business of money movement.
Engagement structures chosen to match how you actually operate — not how consultants like to bill.
Mandates with a defined scope and a clear end date, from a few weeks to several months: architecture reviews, integration audits, platform selection or a specific technical build. Senior-led, no overhead theatre.
We design, deploy and maintain your platform over the long term, under a clear SLA or a fixed annual retainer. You run the business; we keep the systems running.
For a new product or channel, we can co-invest engineering and share in the results: revenue-share or hybrid models, agreed case by case. Best when we both back the outcome.
Whether you’re scoping a new wallet platform, modernising a legacy transaction stack, or simply want a second set of eyes on an architecture — we’d like to hear from you.
