Technology experience that goes the distance. Agricultural roots that go deep.
Hanging Valley Enterprises LLC is a Microsoft Power Platform consulting and software development firm based in Bow, Washington — in the heart of the Skagit Valley. We build purpose-fit solutions for organizations whose problems don't fit the standard software catalog.
Our flagship product, Vegetable Production Management (VPM), is the result of combining over 50 years of enterprise systems experience with the operational reality of a working certified organic farm. That combination is not incidental. It's the whole point.
The last chapter of a long career. And the most interesting one.
Mark Slosberg founded Hanging Valley Enterprises after more than four decades in technology — a career that started with HP67 calculators and Fortran at the University of Washington College of Forestry, ran through the early Apple II era, built and sold an IT integration firm to a public company in 1999, and ended formally as a Managing Director at PwC.
The move to Bow, Washington — triggered in significant part by his son Jacob's and his wife Amy's acquisition of a parcel to locate their then six-year-old certified organic vegetable farm in the Skagit Valley — created an unexpected convergence. Mark's natural resources training, his decades of data and systems integration experience, and the operational reality of a serious commercial farm operation in the family finally found a common problem worth solving.
The result is VPM. Not a product built speculatively for a market — a product built in production, for a real operation, tested against the actual demands of commercial vegetable farming across multiple full seasons.

Natural resources and scientific research training. Early computing. The foundation of a data-driven approach to complex systems.
Apple II at retail → IT integration firm
From selling the first personal computers (and building the first commercial manure digester in Washington state) to building a successful IT integration business — sold to a public company in 1999. That firm developed and implemented systems for Matsushita Avionics, HeathTecna (now Hexcel), Boeing, and the WA State Appellate and Supreme Courts Case Management systems.
14 years in professional services
Leading roles at medium and large professional services organizations, finishing his corporate career as a Managing Director at PwC — where he led PwC's early moves back into technology consulting with a focus on Microsoft and data technologies. Implemented the first WA State Courts public-facing data warehouse, led the technical side of a multi-million dollar turnaround at Chevron's Global Lubricants division, and consulted with Microsoft, Hershey's, Wells Fargo, and numerous other Fortune 500 organizations.

A return engagement at Chevron and a focus on Microsoft Power Platform from its earliest releases. Agricultural roots. Two AppSource-certified products. VPM in live production.
Not a product built for a market. A product built in one.
VPM was developed in active partnership with a certified organic vegetable operation in the Pacific Northwest — a serious commercial farm that has navigated the full growth curve from startup to 100+ acres over more than a decade. That farm is the co-development partner, the beta production site, and the source of the operational knowledge that makes VPM different — the kind of knowledge that can only come from running a certified organic vegetable operation at scale, season after season.
The hard part wasn't writing the code. The hard part was understanding the data — and what it actually means to run a commercial vegetable operation at scale.
Every compliance workflow, every data structure, every Planting Plan Record, Seeding, Harvest Record, Pack Run, and Sales Order in VPM reflects something that actually happened in a real field, in a real season, with real consequences. That's not a marketing claim. It's a development methodology.
The partnership also positions HVE uniquely in the market. Customers who need a modern operating and compliance platform and want technical integration expertise engage HVE directly. Customers who want that same platform plus hands-on consulting grounded in real farm operations will have access to that too — through the farm partnership. Same product, different value wrapper, different relationship.
Ten-plus years building on the platform. Two products certified.
HVE has been focused on Microsoft Power Platform and Dataverse for over a decade — long enough to understand not just how to build on it, but how it ages. The architecture decisions that create problems two years later. The patterns that hold up under real-world load. The customization approaches that stay maintainable over time.
Both HVE products — VPM and RealTime Sales Enablement (RTSE) — are certified and listed on Microsoft AppSource under the ISV Success program. That's not a checkbox. It's a publisher track record that Microsoft and enterprise IT buyers rely on.
The Power Platform choice also has direct implications for customers: your data stays in your own Microsoft tenant, your team can extend the system using AI tools they already have, and you're not dependent on a single vendor's roadmap or pricing decisions.

Small team. Deep experience.
HVE is a focused operation — intentionally so. The people who build the software are the people who talk to clients, and the people who understand the problem domain are the people who designed the architecture.
Over 50 years of experience spanning small business to large global enterprise — including consulting, systems integration, software development, and business process engineering. Built and sold an IT integration firm to a public company in 1999, with clients including Matsushita Avionics, Boeing, and the WA State Courts. Finished his corporate career as Managing Director at PwC, where he led the firm's early return to technology consulting with a focus on Microsoft and data technologies.
University of Washington College of Forestry and the Institute for Environmental Studies, 1979. The natural resources background and the systems integration background finally converged in Bow, Washington, in the form of VPM.
15+ year career spanning nonprofit management and technology operations. Deep experience in workforce management, scheduling, back office operations, and team building.
Brings the organizational and operational discipline to HVE that keeps complex, multi-workstream projects moving — and the judgment to know when something is ready and when it isn't.
Embedded in the regional agricultural economy — not just adjacent to it.
HVE's agricultural engagement goes beyond product development. We have served in a traditional consulting role for regional agricultural organizations including the Puget Sound Food Hub and the NW Ag Business Center — organizations that have been central to the development of the sustainable agriculture ecosystem in the Pacific Northwest.
That positioning matters. VPM wasn't built by observers of the agricultural supply chain. It was built by participants in it — people who understand the relationships, the compliance pressures, and the operational realities because they are living them alongside their clients and partners.
The background is real. So is the product.
If you want to understand whether VPM is the right fit for your operation, the fastest path is a direct conversation.
