We don't talk about AI. We build it.

AI is reshaping how businesses operate, but most owners don't know where to start, which tools to trust, or how to build workflows that actually save time and money. We bridge that gap.
01

Real systems, not slideware

Every workflow we offer is something we set up ourselves, train your team on, and support after launch. No vague strategy decks. No vendor referrals.

02

Operator-built

Twenty-two years running real operations means the technology serves the business, not the other way around. We've lived the labor crunch, the margin squeeze, and the 11pm P&L.

03

Owned by you

When we're done, the system lives in your business and you control it. Update a workflow in ten minutes. Adjust the settings yourself. No lock-in.

About

Geoffrey Arvanitis, Founder & CEO

Geoffrey's love for food and hospitality began at his grandfather's side. A chef in his own right, his grandfather taught him to cook before most kids learn to ride a bike. That early foundation shaped everything that came next.

A college job at a local restaurant turned into a career. After graduating and moving to Washington, D.C., Geoffrey worked at the historic Hawk & Dove on Capitol Hill, a Washington institution famously featured on The West Wing. Returning to Boston, he joined the Marlon Abela Restaurant Corporation (MARC) as bar manager for the opening team at Bistro du Midi, an upscale French Provençal restaurant. There, under the guidance of legendary wine director Olivier Flosse and award-winning Chef Robert Sisca, he learned what world-class hospitality truly means.

Over the next two decades, Geoffrey built and led some of Boston's most notable concepts. As General Manager, he opened Noche, a swanky Spanish fusion restaurant in the South End. He led the launches of the original Temezcal Tequila Cantina and Jerry Remy's Sports Bar (now Tony C's), both of which grew into major chains. He served as General Manager of the iconic Stephanie's on Newbury, opened the award-winning Red Bird in Waltham (where he stayed for six years), and most recently ran River Bar at Assembly Row in Somerville, the largest outdoor patio outside of Boston, navigating it through the COVID era and beyond.

His work hasn't been limited to Boston. Geoffrey has consulted on restaurant, bar, and hotel concepts across the United States and internationally, with projects in Greece, South Korea, and Singapore. He has traveled the world visiting restaurants and wineries, including time at the legendary George V in Paris and a memorable dinner with renowned chef and restaurateur Paul Bert.

Today, Geoffrey is back in Boston, writing a book, running his own ventures, and bringing twenty-two years of operating wisdom to a new generation of business owners through Sage & Stone.

Workflows we build, deploy, and support

From the front desk to the back office, these are the AI systems we build, deploy, and support — win more customers, run leaner, and keep them coming back. Start small and prove value, or go all-in. Every package is a real system installed in your business — set up by us, trained to your team, and owned by you. Exact pricing is scoped on a free 30-minute call — most owners start with one entry workflow and expand only once it's paying for itself.

How It Works

How a typical partnership unfolds

Entry packages prove value fast. Mid-market builds become the core engagement. Most clients convert to a retainer within six months — that's where the partnership compounds.

Most partnerships pay for themselves inside the first year. What the systems replace in manager hours, waste, labor inefficiency, and missed margin is worth significantly more than the investment.

Engagement Outcomes

Results that move the needle

COGS & Labor ↓
A struggling independent restaurant needed a complete operational reset. We took a hard look at the numbers, brought cost of goods and labor down significantly, redesigned the menu from the ground up, and retrained the team on real hospitality. The results were almost immediate, and the restaurant is still thriving today.
Operations Turnaround
10× Faster Ops
A multi-unit restaurant group needed to modernize without losing its soul. We integrated AI into scheduling, inventory, forecasting, and guest data systems. Everything now runs twice as smoothly and ten times faster, and the team has time to focus on what matters most: the guests.
