What does it take for a payments company to win investors’ trust in a crowded market? At the Jefferies Fintech Conference in New York, Paymentus gave us a masterclass in turning scale, AI, and a clear business model into long-term growth.

If you’re an investor, founder, or fintech operator wondering how a payments company can carve market share while avoiding the M&A treadmill, this story is worth your full attention.

The global digital payments market is ballooning, and the biggest winners aren’t just the Stripes or PayPals of the world. Paymentus has quietly turned itself into a billion-dollar contender with AI at the core. For business students, executives, and traders, this isn’t just another conference recap. It’s a roadmap to where the value is moving in fintech.

  1.  Paymentus revenue crossed $1.1 billion, growing nearly 3x since its IPO.
  2.  AI and machine learning drive cost efficiency and customer retention.
  3.  Instant Payment Network is its competitive moat with real-time connectivity.
  4.  Growth strategy leans on organic expansion over expensive acquisitions.
  5.  Market capture remains small, leaving significant upside.


Paymentus’ fireside chat at Jefferies wasn’t the usual investor roadshow fluff. CEO Dushyant Sharma and CFO Sanjay Kalra spelled out how a cloud-based bill payment company can dominate without spreading itself thin. They reminded investors that Paymentus now handles over 600 million transactions annually for more than 2,500 billers, a sign that scale is finally compounding.

Since going public in 2021, revenue has jumped from $400 million to $1.1 billion. That’s the kind of trajectory fintech investors look for but rarely see delivered post-IPO. Yet, the company has still captured only 3.5 percent of its addressable market, leaving room for growth.

One of Paymentus’ most valuable assets is its Instant Payment Network. Instead of being another middleman, the IPN connects tens of thousands of billers and banks directly, offering real-time payment rails. With FedNow and RTP integration on the horizon, this could become a sticky moat, hard for rivals to replicate.

AI is not just a buzzword here. Paymentus uses it in fraud prevention, transaction routing, and customer engagement, areas where savings per transaction add up at scale. If they maintain efficiency while expanding into newer rails like stablecoin payments, profitability could widen beyond the standard “rule of 40” fintech target.

On strategy, Sharma made it clear: Paymentus prefers organic growth. While many peers chase splashy acquisitions that dilute focus, the company is disciplined about M&A. For investors, that means fewer surprises on the balance sheet and a stronger long-term margin story.

The company’s client base is diverse as utilities, healthcare, insurance as which buffers it against downturns in any one sector. And by charging on a per-transaction basis, its incentives stay aligned with billers’ ROI, something investors often underestimate.

Analysts watching the session noted that Paymentus is shaping up to be a challenger in the digital billing race, not by brute force but by quietly building infrastructure that others will struggle to match. As one report from Morningstar highlighted, the company’s backlog and financial discipline suggest it could accelerate revenue growth while maintaining profitability.

For founders and executives, the lesson is clear. Scale comes from compounding your edge, not chasing every trend. For investors, the question is whether Paymentus’ stock is priced for just 3.5 percent of TAM or for the multi-billion-dollar runway still ahead.


5 to Do and Don’t for readers:

  1.  Do watch how Paymentus scales IPN with FedNow and RTP.
  2.  Do track AI adoption in billing as a real cost lever, not just hype.
  3.  Do consider revenue growth with margin discipline as a stronger story than M&A-driven expansion.
  4.  Don’t assume 3.5 percent market capture means saturation. It signals upside.
  5.  Don’t ignore the per-transaction pricing model. It’s a built-in hedge for clients and investors alike.
