Big Rock brings cannabis to the table

The San Francisco investment and advisory firm took its restaurant connections into the fields. At Sonoma Hills Farm, the result is a cannabis business built around flavor, farming, and the people who know how to host.

A cannabis strain can begin with an unusually precise request: make it smell like Meyer lemon and a Northern California forest. That was the brief from Lazy Bear, the San Francisco restaurant, to Sonoma Hills Farm. Three years of selection followed. Seven finalists reached the restaurant team. The eventual release, Lazy Bear Reserve, makes a useful introduction to the investment firm behind the farm. Big Rock has an appetite for businesses where taste, trust, and cultivation meet.

THE STORY IN THREE BITES
  • Big Rock invests in and advises businesses across cannabis, food, and hospitality.
  • It also owns and operates Sonoma Hills Farm, giving the firm a working agricultural business.
  • Chef collaborations turn its hospitality connections into products with a specific point of view.

The address book becomes an ingredient

Big Rock’s hospitality interests predate these products. It reports investing in Tacolicious in 2009 and beginning its investment in Big Night restaurants with Park Tavern in 2011, followed by Marlowe and The Cavalier. These are businesses that have to persuade people to return. An attractive launch gets you a first visit. The second depends on what happens at the table.

The firm describes its work as strategic advice and consulting for companies and investors, from formation through growth capital. Its founders are Mike Harden, the CEO, and Shauna Harden, whose work includes executive producing the cannabis documentary Lady Buds. Harden’s investment background and the firm’s hospitality network give it a particular place in the market: money and advice attached to operating experience.

For a founder, the attraction is access to people who understand both a brand and the machinery behind it. For an investor, it is a view across related businesses. Big Rock’s model combines investing, advisory work, and owning a farm. Each activity asks a different question: what deserves backing, what needs fixing, and what can actually be produced?

First, permission to plant

The farm property was acquired in 2017. Its history includes chickens and prize-winning pumpkins, which is a pleasing reminder that agricultural reinvention has happened here before. Cannabis added a much more elaborate approval process.

MJBizDaily reported that Big Rock’s farm spent three years in licensing and had to meet nearly 200 land-use conditions before planting. Screening plants from neighbors, cameras, and high fences were part of the bargain. The one-acre cultivation permit arrived in 2019. The early bottleneck was permission. A promising market and suitable soil could not supply that.

“We see cannabis as the third leg of hospitality.”

Keefer, who previously worked as culinary gardener for the Thomas Keller Group and The French Laundry, helps explain the farm’s direction. A culinary gardener pays attention to an ingredient before a diner ever sees it. Applied to cannabis, that habit makes aroma, origin, and cultivation part of the product brief.

A package with homework behind it

Lazy Bear Reserve shows the process in detail. The farm says Humboldt Seed Company helped refine the selection. Chef David Barzelay and COO Colleen Booth wanted citrus and conifer notes connected to the restaurant’s cooking. The resulting cultivar reached dispensaries as flower and pre-rolls. A restaurant’s preferences had become specifications for a crop.

Another collaboration supplies a more practical test of demand. Sonoma Hills Farm says its earlier limited-batch Pink Jesus chews sold well enough for Kiva Lost Farm to make them permanent. The farm grew a dedicated crop, froze the harvested flower, and worked with extraction partner Leef. The useful lesson is sequencing: try the partnership, watch the response, then build a repeatable supply arrangement.

In March 2026, the farm launched its own first edible with chef Chris Cosentino. Spicy Arugula Gummy uses Meyer lemon, wild fennel pollen, lemon verbena, and sea salt. The name sounds like a salad special. The ingredient list helps explain why a chef belongs in the development process: flavor decisions give the collaboration substance beyond the name on the box.

Provenance needs paperwork, too

The same concern with consistency appears upstream. Big Rock’s portfolio includes Node Labs, which uses tissue culture to clean, preserve, and propagate cannabis genetics. Its customers include cultivators and breeders. The problem is concrete: a prized variety can be damaged or lost, and a recognizable brand needs a dependable crop.

At Sonoma Hills Farm, certification supplies another kind of evidence. In 2021, CCOF recognized its cannabis operation and Sensiboldt Organics as the first farms certified under California’s OCal program. OCal establishes comparable-to-organic standards. It gives buyers a defined cultivation standard to look for, alongside the farm’s account of its practices.

That combination is Big Rock’s answer to a crowded market: genetics, documented farming, and collaborators with an identifiable taste. It still needs distribution. The farm’s retailer list, dated September 30, 2026, reports more than 90 California dispensaries. Those are retail partners, a crucial distinction when imagining the scale of the operation.

The visitor takes the plant home

In September 2026, the farm offered a different introduction to agriculture: pick-your-own industrial hemp. Registration cost $25 per car, with plants starting at $100 and at least one plant required per car. Visitors received harvesting and curing instruction. Co-host Christina Wong’s account describes people walking the fields and taking their plants home.

The boundary matters. That event concerned industrial hemp. The farm’s current cannabis-tour signup specifies no consumption, sales, or samples on site. Hospitality ambitions must fit the actual permissions of the business. Any entrepreneur copying the approach needs patience, capable production partners, and a viable route to customers. A clever collaboration cannot substitute for those things.

Big Rock’s most interesting idea is that an investment network can become a production network. The relationships help define what to make; the farm forces that idea through soil, seasons, paperwork, and a retailer’s shelf. Somewhere in that journey, a restaurant’s request for Meyer lemon and redwood becomes a product someone can recognize.
