Helping one of the leading pet subscription brands scale without interruption.
Bullymake serves hundreds of thousands of customers at scale. At that volume, site performance, recurring billing, customer control and fulfillment are not only technical concerns. They decide revenue, retention and whether customers keep trusting the brand. Napstack became a deeply integrated partner, combining commercial thinking, customer experience and engineering so the business could operate at a higher level.
Napstack's work
- Re-engineered the core subscription architecture, fulfilment pipelines and customer portal.
- Migrated off a legacy monolith with zero downtime and zero dropped webhook payloads.
- Rebuilt the merchandising and checkout story so proof lands before price.
- Subscription architecture
- Ecommerce engineering
- Fulfilment automation
- Conversion design
- Retention systems
This is what market experience looks like in practice: understanding the customer, the commercial stakes and the infrastructure it takes to deliver at scale.

The challenge
- Legacy monolith bottlenecks during peak monthly recurring billing sweeps, without service degradation.
- Complex multi attribute box customisation across weight tiers, chewer durability and allergy exclusions on live subscriber profiles.
- Order fulfilment delays and label generation rate limit failures across high throughput carrier APIs.
The approach
- A serverless edge queuing pipeline with in memory caching to ingest and process high volume subscription webhooks asynchronously.
- Modular web component widgets for real time subscription management and dynamic checkout upsells.
- An automated fulfilment dispatch engine wired directly into carrier APIs for instant warehouse batch label creation.
The outcome
Napstack delivered a fault tolerant, highly scalable subscription ecosystem that held 100% uptime through the entire platform migration. Bullymake gained a 3.5x acceleration in warehouse dispatch, zero dropped webhook payloads and higher average order value through integrated checkout extensions, laying the foundation for continued multi million dollar expansion.
