The Prop plane is kicking 2026 off strong — setting our sights on higher altitudes in the months ahead. As a wholesale ISO, we now fully control the merchant experience across our supported platforms, including Fiserv, TSYS, and Visa Platform Connect (VPC).
This milestone marks more than just scale — it reinforces our commitment to delivering a truly differentiated payments experience for our merchants and integrated partners.
From day one, our goal has been simple and unwavering: build payments the right way. Today, that vision comes to life through full ownership of the merchant lifecycle, allowing us to deliver a seamless, high-touch payments experience from onboarding to long-term growth.
As a wholesale ISO, Propelr owns the payments experience end to end. With complete autonomy over pricing, underwriting, risk monitoring, onboarding, and support, we’re able to design payment solutions around our clients — not force them into one-size-fits-all models.
This flexibility means faster decisions, smarter customizations, and solutions that align with each client’s operational realities — without ever compromising service quality or performance.
By fully owning the risk and underwriting process, we’ve removed unnecessary layers and bottlenecks from the equation. Instead, our clients receive:
Instead of waiting on third parties, our partners get swift resolutions from a team that knows their business and is invested in their success.
Support isn’t an afterthought at Propelr — it’s a core differentiator. On-demand support, paired with full ownership of the merchant relationship, enables us to build deeper trust, stronger loyalty, and sustainable long-term growth that supports our clients’ goals.
When you work with Propelr, you’re backed by a team that stays with you at every stage — no handoffs, no gaps, no compromises.
This next chapter as a wholesale ISO isn’t just about control — it’s about possibility. Greater flexibility. Better experiences. And a payments model designed to scale with our clients, not around them.
