Monument Capital Partners
Scott Asbjornson established Monument Capital Partners in 2008 after an operating career that included engineering leadership roles at AAON, the publicly traded HVAC manufacturer where he later served as a director. The firm is structured as a private investment vehicle that draws on Asbjornson's industrial domain expertise rather than a broad multi-sector mandate, with a focus on companies where mechanical engineering and software intersect. Monument concentrates on growth-stage industrial technology and enterprise software businesses. Public record confirms the firm's active involvement as a board-level investor in AAON, where Asbjornson has held a directorship and participated in governance decisions, and in Syntex Industries, an Iowa-based manufacturer of engineered sealing and wear components used in heavy industrial applications. The firm's typical check size, geographic screening radius, and total number of active platform investments remain private. The firm operates from Tulsa, Oklahoma — a location that shapes its sourcing strategy toward the industrial Midwest and southern manufacturing corridors rather than traditional coastal venture markets. Monument does not publicly report assets under management or maintain a large investment team, operating closer to a family-backed investment office than a conventional institutional fund. January 2024: Scott Asbjornson retired from the AAON board of directors after more than a decade of service, a move that may signal increased attention to direct portfolio management at Monument (per AAON SEC filings, 2024). Monument's structural differentiator is its operator-anchored governance model. Asbjornson is not a career financier but a former plant manager and product engineer who sits on portfolio company boards and participates in operational decisions — a posture that makes the firm's capital function more like executive co-ownership than passive institutional allocation. This approach limits portfolio breadth in exchange for depth on each holding, and the firm has not syndicated its positions publicly or raised outside limited-partner capital.

Does Monument raise outside capital or operate as a single-family vehicle?

What types of companies does Monument target?
Monument concentrates on growth-stage businesses at the intersection of industrial technology and enterprise software. Confirmed portfolio exposure includes engineered mechanical components manufacturing and commercial HVAC systems, with the firm favoring companies where its principal can contribute operational rather than purely financial oversight.
Why is Monument Capital Partners based in Tulsa?
The Tulsa location reflects Scott Asbjornson's personal and professional roots in Oklahoma manufacturing, including his long association with Tulsa-based AAON. The geography also positions the firm closer to industrial-company density in the Midwest and southern US than a coastal financial center would, aligning with its sector focus.
Does Monument participate in fund commitments or only direct deals?
The firm's publicly documented activity consists of direct equity positions with board-level engagement. There is no evidence of commitments to third-party funds, club syndications, or co-investment partnerships, consistent with a concentrated direct-investment mandate.
