E & I Ventures

E & I Ventures

E & I Ventures was formed in 2016 by co-founders Geoffrey Mobisson and Doug Guilbeau, combining Mobisson's MIT- and Harvard-honed operator experience with Guilbeau's CRM and digital-marketing leadership. The firm's genesis is rooted in two decades of their own startup journeys, positioning it explicitly as a capital partner that also inserts itself into the operational fabric of its portfolio companies. The wealth backing the firm is not publicly disclosed. The firm writes minority equity and debt checks into early-stage technology companies, concentrating on seed, angel, and Series A moments. Its stated sweet spot is the post-proof-of-concept transition — companies that have validated a product but now face the operational, go-to-market, or scaling challenges that Mobisson and Guilbeau navigated as startup founders. The duo brings direct operating heft: Guilbeau concurrently runs Levementum, an E & I portfolio company and CRM consultancy; Mobisson previously founded the Oracle-focused consultancy Dataweb and e-commerce firm Empath Solutions. The portfolio spans enterprise software and digital transformation, with Levementum serving as the only confirmed portfolio holding. Geographic focus is domestic, with headquarters in Chandler, Arizona. E & I Ventures operates as a lean partnership from its Chandler, Arizona base. Total deployment figures and team headcount are not publicly disclosed. The firm does not advertise separate philanthropic vehicles, institutional fund structures, or peer-network club memberships. Its origination model is relationship-driven, soliciting direct inbound contact from founders who reach out through its website. No named fundraising events or new vehicle launches have been publicly recorded in the last 24 months. The firm's principal structural differentiator lies in its operator-first composition. Both managing partners sustain active executive roles in the portfolio — Guilbeau as CEO of Levementum — rather than functioning solely as allocators. This blurs the boundary between principal investor and operating executive, creating a concentrated thesis that relies on the founders' specific domain expertise in CRM, e-commerce, and enterprise consulting rather than a broad sector-agnostic mandate. It also means the firm's scale is tied to the bandwidth of its two co-founders.
