About Peyya

Peyya is building the next-generation digital wallet platform for the creators, doers, and builders of the digital economy.

We unify payments, self-sovereign identity, verifiable credentials, and user-owned data into a single platform — enhanced by a personal AI companion — giving users full control and utilization of their money, credentials, and digital footprint.

Peyya eliminates the delivery-versus-payment dilemma by replacing trust with proofs embedded directly into the transaction layer — automating conditional escrow payments, revenue distribution, and secure agreements under full user control.

Where trust causes f*ck-ups, Peyya replaces trust with proof embedded in code.


The Opportunity

Peyya today is a validated vision and a strong foundation — built from years of research, proofs-of-concept, and real-world learnings.
Now we’re looking for a true technical co-founder to shape, build, and own the product journey together with the founder from day one.

This isn’t about joining a startup.
This is about building the startup — from 0–1.


What You'll Do

  • Co-create the product vision, technical architecture, and go-to-market strategy.
  • Build the MVP — frontend, backend, and blockchain/identity/payment integrations.
  • Validate fast, launch simple, and iterate based on real feedback.
  • Build structured, scalable, documented systems from day one.
  • Design with product, user experience, and scalability in mind.
  • Set the foundation for Peyya’s future engineering and technical culture.

Who You Are

  • You want a true co-founder role — not just an early employee position.
  • You think like a product builder, not just an engineer.
  • You can plan, execute, and own independently.
  • You move fast, but you never compromise on structure or scalability.
  • You believe in user ownership, decentralization, and privacy — always balanced with real-world usability.
  • You value transparency, action, and shared success over ego and titles.

Our Tech Direction

Peyya is Open Source-first and an Open Startup.

We believe in building simple, open, scalable, and privacy-respecting systems.


What We Offer

  • True co-founder equity and full ownership.
  • Freedom to define and lead technical strategy and execution.
  • A founder-first culture built on transparency, action, and respect.
  • The opportunity to build something that truly matters — from scratch.

If you want to build — not just join — let's talk.

Punch

Punch is a fintech startup developing next-generation payment infrastructure. At Punch, we are fueled by the fundamental belief that increased trust and financial freedom create opportunities and financial inclusion that liberates people to live life to its fullest. By bridging the gap between traditional banking and decentralized finance, we bring the next generation of decentralized payment infrastructure based on blockchain payment rails and distributed ledger technology, to the masses. Allowing money to move effortlessly between people, companies, and nations, all over the world, in any way they choose, without the boundaries of intermediaries and legacy technology. All while gaining transparency, traceability, and accountability. And this, we believe, will empower people and entrepreneurs to join and thrive in the global economy and contribute to democratizing society, reducing poverty, and creating a sustainable global economy. Our fintech platform brings together everything needed for companies to issue Central Bank Digital Currency along with the infrastructure and building blocks to design and implement blockchain-powered payments in any solution. The platform can power anything from SaaS and Marketplace payments to CPQ and CRM-powered payments, automated micropayments, decentralized escrow payments, and everything in between. All transactions are made via our blockchain payment rails which make them instant, and cross-border payments are made directly between sender-receiver without any routing, hence reducing time, cost, and risk.
