100 Day

What 100 Day does

100 Day is a privately held management consulting firm founded in 2020 and headquartered in Chicago, Illinois, specializing in transaction advisory, operational improvement, and sales enablement services for the lower middle market private equity segment. The firm is structured as an independent, partner-owned practice led by Chris DeMichael and George Florea, with a team of 11-50 employees drawn from prior roles within investment community IT functions, enterprise acquisition onboarding and brand migration teams, and large agency-level branding and sales enablement groups.

The firm's service portfolio is organized around three trademarked core solutions: Ready Check 360° (transaction advisory covering IT due diligence, sell-side due diligence, carveout planning, integration planning, and asset identification), Ops Rx (operational improvement including SpotCheck IT diagnostics, program management, CRM/ERP/HR integration, and Asset Secure asset protection), and Sales Mobilizer (sales enablement including Brand Fortify, SalesRx toolkits, and Sales Accelerator SpotCheck diagnostics). These solutions span the full private equity investment lifecycle from buyouts and add-ons through carveouts, integrations, and exits.

100 Day operates on a professional services revenue model with quote-based, multi-year engagements tailored to lower middle market deal sizes. Go-to-market is relationship-based and direct, leveraging a company website with contact forms, a phone line (+1 312.672.1266), a sales email ([email protected]), and a LinkedIn presence. Primary customers are private equity firms, with secondary segments including strategic buyers and venture capital portfolio companies. No external funding has been raised, and the firm does not disclose revenue or financial metrics.
