Norwest Partner Reveals Founder Sales Test Before Backing
Norwest partner Sean Jacobsohn explains why he joins prospect sales calls before writing checks and outlines where new software upstarts can unseat entrenched enterprise giants.

Sitting in Sand Hill Road boardrooms during my early days tracking Silicon Valley dealmakers, I observed a repeating tragedy play out across early-stage enterprise ventures. Gifted software engineers would unveil stunning architectures, elegant codebases, and seamless database configurations, convinced that technical perfection alone would force corporate America to open its checkbook. Then came the brutal confrontation with corporate procurement officers, vendor committees, and enterprise sales cycles. Without a founder capable of looking an enterprise buyer in the eye and closing a contract, even brilliant technology invariably ran out of cash. That hard reality still separates fundable startups from expensive academic experiments.
Sean Jacobsohn, a general partner at Menlo Park venture firm Norwest Venture Partners, has elevated that realization into an unbending investment filter. Before writing a check from the firm’s $3B seventeenth investment pool, Jacobsohn joins prospective client calls arranged directly with the startup chief executive. He is not there to observe software demonstrations or review interface screens. He is inspecting how well an engineering-minded creator can pitch, negotiate, manage objections, and close business deals in the wild. If the leader stumbles when selling to live prospects, the investment dies right there.
I have tracked Jacobsohn’s career across several venture cycles, stretching back to his operating days inside fast-scaling business software providers. He served in senior management positions at WageWorks and Cornerstone OnDemand as both organizations climbed from modest single-digit revenues to multi-million-dollar ARR scale, before spending time inside Upwork. All three businesses subsequently completed public stock listings. When an investor brings decades of hands-on sales and commercial distribution experience to early funding stages, his advice carries weight that pure financial theorists cannot replicate.
The Real Trial on the Sales Line
Almost every software founder presenting pitch decks in Jacobsohn’s office brings strong technical credentials or specialized software backgrounds. Yet Jacobsohn insists that technical capability represents only a starting ticket. A technology chief must convince skeptical enterprise purchasers, recruit elite software talent without high compensation packages, woo institutional investors, and persuade strategic distribution partners. Salesmanship touches every single corporate interaction a chief executive conducts.
To verify that commercial instinct, Jacobsohn sets up real sales calls with potential customers across his personal corporate network. He sits silently on the line, evaluating whether the entrepreneur listens actively, addresses customer doubts, or retreats into dense jargon when pressed on contract terms. Over his tenure at Norwest, where he oversees 15 active software portfolio firms spanning early seed stages to over $300M in yearly receipts, he has walked away from technically gifted teams purely because the founders could not sell their vision to corporate prospects.
That filter reflects the current corporate buying climate. Chief financial officers and corporate technology heads have slashed experimental software trials, demanding clear, rapid returns on every dollar spent. An entrepreneur who cannot articulate immediate commercial utility within five minutes of an executive meeting will never navigate modern enterprise procurement mazes.
Unseating Giants in Corporate Finance
While venture investors chase headline-grabbing consumer gadgets, Jacobsohn concentrates heavily on back-office applications, particularly the corporate suite supporting financial chiefs. Across the finance sector, corporate buyers possess dedicated capital budgets and pay high annual retainers for software. Yet hundreds of corporate departments still rely on aging on-premise platforms or awkward initial web adaptations built two decades ago.
A recent Norwest market survey mapped over 500 corporate tools serving enterprise finance departments, concluding that three out of four represent outdated platforms ripe for replacement. Many of these legacy packages run automated workflows, but they do so through brittle, clumsy software interfaces that require excessive manual oversight. Newer software entrants can capture immediate market share by replacing these cumbersome interfaces with modern cloud systems.
Nevertheless, Jacobsohn issues a stern warning regarding the use of machine learning inside accounting applications. While predictive algorithms excel at workflow coordination, sorting documents, and summarizing business correspondence, relying on autonomous machine models for direct financial arithmetic remains hazardous. Predictive language systems make arithmetic errors because they are word-prediction mechanisms rather than deterministic calculation engines. In audit-heavy corporate balance sheets, where a misplaced decimal point invites regulatory penalties, calculations must remain locked in traditional deterministic math code.
Targeting the Vulnerable Edges of HR Monoliths
When evaluating human capital technology, Jacobsohn applies a different strategic calculus. Market leaders like Workday, ADP, SAP, UKG, and Dayforce hold unshakeable dominance over foundational enterprise workflows, including payroll management, benefits administration, and base workforce registries. Convincing a Fortune 500 conglomerate to rip out its central payroll platform involves terrifying administrative headaches, high costs, and severe operational hazards. As a result, early startups attempting direct frontal assaults against those entrenched platforms almost always burn out.
Instead, Jacobsohn directs entrepreneurs toward secondary product categories where massive conglomerates maintain weak, neglected software add-ons. Major platform providers focus corporate resources on their cash-cow applications, leaving specialized workflows like contractor compliance, cross-border equity management, and specialized workforce logistics poorly serviced. A targeted startup can build a superior product around one overlooked workflow, win enterprise accounts by solving a specific administrative headache, and establish an initial beachhead inside large organizations without threatening central payroll databases.
Building enduring software today demands vertical focus and deep domain competence rather than broad, generic tools that generic software tools can clone overnight. By backing founders who possess specialized industry knowledge and testing their sales fortitude before wiring initial funds, Norwest’s strategy shows that in tough economic cycles, the ultimate enterprise moat remains an undeniable ability to close the deal.
