15Y doesn't hand off a strategy deck and disappear. Here's what happened when we stayed through execution.

$50MM ARR 5-Yr Target Hit in Year One
EBPP · EMBEDDED BANKING · NORTHEAST U.S.

Embedded bill presentment & payments for a large commercial bank

A top-tier commercial bank turned a five-year growth plan into a one-year result by embedding EBPP directly into its banking experience.

Challenge

A large commercial bank headquartered in the Northeast U.S. needed to modernize an aging bill payment experience. Adoption had stalled, the underlying architecture wasn't built for embedded, in-channel presentment, and internal teams lacked the specialized payments expertise to move fast without introducing compliance risk.

Approach

15Y led end-to-end product design and vendor/processor evaluation for an embedded electronic bill presentment and payments (EBPP) solution, built directly into the bank's consumer and commercial digital channels. We defined the compliance framework alongside the product architecture from day one, then built and executed the go-to-market plan — including internal sales enablement and biller/merchant onboarding — to drive adoption at launch.

Result

The program generated $50MM in ARR by its second year, reaching a target originally modeled as a five-year milestone within Year One alone — driven by a launch strategy built for adoption, not just availability.

+40% Portfolio Growth in 9 Months
PARTNERSHIPS · SAAS GTM · SOUTHEAST U.S.

Building the partner ecosystem for an emerging payments integrator

A growing payments integration provider needed a partnership motion to scale beyond direct sales — and got measurable portfolio growth within three quarters.

Challenge

An emerging payments integration provider based in the Southeast U.S. had strong technology but no repeatable way to scale distribution. Growth depended almost entirely on direct sales, with no partner tiering, incentive structure, or enablement model to bring ISOs, SaaS platforms, and gateways into the fold.

Approach

15Y designed a partnership ecosystem strategy from the ground up — partner tiering and incentive economics, prioritized target verticals, and enablement materials that let new partners activate quickly. We worked alongside the client's team to stand up a scalable onboarding motion for SaaS partners specifically, turning partnership into a repeatable growth channel rather than a one-off deal.

Result

Within nine months, the client's overall customer portfolio grew 40% — with the new partner channel becoming a durable, repeatable source of growth alongside direct sales.

2X ARR $20MM → $40MM in 18 Months
VERTICAL EXPANSION · ORG TRANSFORMATION

Expanding a checkout platform into government & public services

Entering a new, highly specialized vertical required more than a roadmap — it required rebuilding organizational capability from the inside out.

Challenge

A payment checkout solution provider at $20MM ARR wanted to expand into government and public-services verticals — markets with distinct compliance, procurement, and integration requirements the organization had never operated in. The gap wasn't technology; it was organizational readiness.

Approach

15Y led an extended organizational transformation initiative alongside the vertical expansion strategy: mapping the specific technology and process requirements of government and public-sector payments, building industry-specific integrations, and designing an associate learning & development curriculum to get teams to mastery quickly on unfamiliar regulatory and technical terrain.

Result

The platform doubled ARR from $20MM to $40MM in 18 months, powered by successful entry into a new, complex vertical — and an organization built to sustain it, not just launch it.

Why 15Y

Payments was growing fast. It wasn't innovating fast enough.

15Y was founded in 2022 on a simple belief: the payments industry was expanding rapidly, but new entrants — armed with modern technology but little payments expertise — were building products on outdated assumptions and aging rails.

Payments expertise and future-proofed design are our differentiators. But our heartbeat is something simpler: genuine care for our clients, and for the customers they serve.

We believe high-quality outcomes and speed to revenue realization aren't a trade-off. With the right planning, processes, performance, and people, they can co-exist.

01 / EXP

Certified payments expertise

Every engagement is staffed by practitioners with hands-on payments backgrounds — not generalists finding their footing on your program.

02 / BUILD

Strategy through execution

We don't stop at the strategy deck. We build the plan and stay through launch to make sure it actually ships.

03 / TECH

Deep technical fluency

Advanced product development, complex multi-layer SaaS integrations, and disciplined project management.

04 / AI+H

Human potential, AI-enabled

We embrace the potential of artificial intelligence — in service of, never in place of, human judgment and care.

Methodology

We absorb the complexity. You get a clean path to launch.

Card network rules, legacy cores, compliance regimes, vendor contracts, and internal stakeholders rarely move in sync. 15Y's methodology is built to take that tangle in — and hand back a single, disciplined path to market.

01

Discover

Map stakeholders, current-state architecture, rail dependencies, and existing vendor commitments.

02

Design

Build product and compliance architecture together, from the start — not compliance bolted on after design.

03

Structure

Negotiate and align card networks, processors, payfacs, and sponsor banks in parallel, not in sequence.

04

Build

Manage multi-layer SaaS integration, certification, and testing with disciplined project management.

05

Launch

Execute the go-to-market plan — sales enablement, onboarding, and a compliant rollout to the field.

06

Optimize

Monitor performance against target, and iterate the program as adoption and volume scale.

Engagement

Curated to how you actually need help.

Short-term or long-term. Advisory or embedded delivery. 15Y flexes to the shape of the engagement, not the other way around.
