What began as a Toast POS cleanup with 5&5 quickly evolved into a full-scale digital transformation, streamlining menus, standardizing reporting, and reducing vendor friction. Now, as the brand scales nationwide, 5&5 serves as its go-to partner for tech rollouts, daily support, and cross-platform management.
A growing brand built for scale.
Founded by celebrated chef Tony Gemignani, Slice House is a fast-casual pizza brand born out of San Francisco and built on authenticity and craftsmanship. With a menu rooted in regional styles—New York, Detroit, Sicilian—the concept pairs quality ingredients with a high-efficiency model that’s made it a favorite among franchise operators.
When CTO David Denton joined the team, Slice House had five open locations—and more than 130 development agreements signed. But with limited internal bandwidth, Slice House needed support to ensure its digital infrastructure could scale with its growth trajectory.
Slice House was expanding quickly, but every franchise location operated its own Toast POS instance, managing menus independently, and had no shared system for user permissions. This decentralized setup created inconsistent guest experiences, fragmented reporting, and occasional operational disruptions.
At the same time, the brand was preparing to roll out new platforms, including Paytronix, ezCater and Restaurant365 but they didn’t have the internal resources to manage such a large-scale transformation.
“Without a permanent team, I was really struggling to figure out how we’d meet all the demands of what we needed from a digital and technology perspective.”
– David Denton, Chief Technology Officer
The rollout of Paytronix introduced a more sophisticated loyalty, gift card, and order & delivery framework, but the transition required significant technical coordination. Migrating from ToastTab’s native ordering to a multi-system setup involved data mapping, platform configuration, and guest experience adjustments. That’s when they turned to 5&5.
Slice House initially brought 5&5 in to conduct a full audit and cleanup of their Toast POS databases. The team worked to streamline and standardize the Toast builds, improving consistency across locations, reducing operational disruptions, and laying the foundation for centralized control. By implementing role-based permissions, the team also curtailed unauthorized menu edits and gave corporate more visibility and oversight.
Even before the cleanup was complete, 5&5 began tackling additional challenges, stepping in for Toast support, guiding franchisees through menu changes, and acting as a frontline resource for day-to-day operations.
David recalls, “We started leaning on 5&5 almost immediately. There’s absolutely no chance we would’ve been able to move this fast without them.”
From there, the partnership expanded. 5&5 led the implementation of Paytronix for online ordering, loyalty, and gift cards—navigating bugs, resolving broken features, and coordinating a complex migration from third-party marketplaces like DoorDash, UberEats, and Grubhub. Acting as the technical intermediary, 5&5 assisted Slice House with platform challenges and helped maintain guest experience throughout the transition. In addition, 5&5 stepped in to assist with the implementation and manage other aspects of the evolving tech stack, including ezCater and Restaurant365.
With vendors frequently rotating support reps, 5&5 became the steady, reliable voice, managing communications, resolving issues, and keeping rollouts on track.
Areas of Support
Since partnering with 5&5, Slice House has scaled from 5 to more than 25 locations, with plans to double that by the end of 2026 and another 100+ in development. Rather than building out a costly internal team, they’ve relied on 5&5’s deep bench of platform experts, gaining access to broad technical capabilities without the overhead of multiple specialized hires.
“Hiring internally would’ve been expensive, and even then, it’s nearly impossible to find one person who’s good at three or four different tools. With 5&5, we got all of that in one place and it’s been a game-changer for our ability to scale.” says David.
From Toast to Paytronix to R365, 5&5 now supports the full ecosystem—removing vendor friction, coordinating platform rollouts, and providing a single point of contact for ongoing support. That consistency has been critical for the Slice House team, especially when vendor reps change or go MIA mid-implementation.
More than just an implementation partner, 5&5 is now deeply embedded in Slice House’s long-term technology strategy, helping shape product roadmaps, advising on platform decisions, and even stepping in during high-pressure moments like weekend grand openings. For David, the relationship has evolved into something far more integral: they see 5&5 as a trusted partner who operates like a key internal leader.
As Slice House continues its aggressive expansion, 5&5 remains embedded in every layer of the brand’s digital roadmap. From fine-tuning loyalty programs to supporting future tech stack migrations, 5&5 brings expert platform knowledge, operational support, and strategic foresight.
