Boston-based Building Engines, a cloud-based provider of on-demand property management software for the commercial real estate industry, has appointed two new executives to its leadership team; David O’Connor as Chief Financial Officer, and Mark Feldman as Vice President of Marketing. The company also announced that Scott Sidman has been appointed Chief Marketing and Strategy Officer. Sidman previously served as the company’s Senior Vice President of Marketing.

O’Connor comes to the company from Buildium, where as CFO he raised $90 Million in funding and helped grow the company by 250%, leading to the sale of a majority interest in the company to Sumeru Equity Partners. He brings financial, strategic management, and corporate development experience with fast-growing technology companies including AppNeta, ServiceCEO and Oblicore.

Feldman brings extensive demand generation, corporate communications and product marketing experience to the Building Engines team. Most recently, as Vice President of Marketing at Motion Recruitment Partners, he was responsible for developing a high-performance marketing organization that drove revenue growth by $100 Million and community membership by 7X. He has been a catalyst for high-growth software and services companies including Korn Ferry, Backupify, AgION Technologies, and NetProspex, where he was instrumental in expanding the company’s go-to-market strategy and establishing industry leadership leading to its acquisition by Dun and Bradstreet.

In his new roles as Chief Marketing and Strategy Officer, Sidman will continue his 12-year tenure with the business to continue leading strategic marketing and growth opportunities for the company. He will focus on expanding Building Engines’ relationships in the broader real estate market to create customer-centric product and company growth initiatives. He will also focus his efforts internally to ensure the customer experience with Building Engines is consistent with its brand promise.
