Top Stack

What Top Stack does

Top Stack is a US-based staffing and recruiting firm headquartered in Malvern, Pennsylvania, with a regional office in Baltimore, Maryland. The company places professionals across five primary specialty verticals—Finance & Accounting, Technology, Marketing, Supply Chain & Logistics, and Government Services—with Human Resources as a secondary segment. Its service portfolio is organized around three placement models: Direct Hire (permanent placements aligned to company culture and goals), Contract (flexible short-term staffing), and Contract-to-Hire (interim placements convertible to permanent roles). Revenue is generated through transaction-based placement fees, with pricing not publicly disclosed and typically structured as contingency-based placement fees or hourly bill rates for contract workers.

The firm operates a sales-led, relationship-driven go-to-market model. Recruiters engage employers directly to understand hiring needs and culture, then match candidates accordingly. Top Stack supplements direct outreach with a self-serve job-search portal (jobs.topstackgroup.com), a Consultant Resource Center for deployed talent, a blog content program (active since 2023), and organic social presence on LinkedIn, Facebook, and Instagram. Underlying technology is a standard corporate website and job portal rather than a proprietary AI-driven matching platform; the company's stated differentiator is hands-on, authenticity- and cultural-fit-focused recruiter engagement rather than algorithmic sourcing.

Top Stack is privately held with 11–50 employees, has not raised disclosed outside funding, and operates as an independent corporation domiciled in Pennsylvania. Leadership includes co-founder Alexa Scalzi (Chief Revenue Officer) and founder Michael Masiello (CEO), per disclosed management data. Customer evidence is drawn from named enterprise testimonials spanning financial services, manufacturing, and Inc. 5000-ranked organizations, though revenue mix and concentration are not disclosed. The company has grown from a Pennsylvania base to include a Maryland office and has broadened its vertical mix over time, but remains a regional Mid-Atlantic staffing firm with no public partnerships, patents, awards, or AI/technology differentiation.
