What SIZE does

SIZE is a US-based professional services advisory firm that supplies fractional and interim C-suite executives — CEO, CFO, COO, CMO, CHRO — to venture-backed and private equity-funded growth-stage companies. Founded in 2020 by Brian Schwartz, Jim Winett, and Craig Kornblau, the firm has assembled a bench of approximately 21 vetted senior operators organized around ten capability areas including Brand Development, Digital Marketing, Executive Search, Finance, Growth, HR Support, Operations, Product Development, Public Relations, and Restructuring. SIZE does not develop proprietary technology platforms; its product is the embedded deployment of experienced executives who carry decision-making authority into client leadership teams during transitions, scaling phases, and exit preparation.

The firm operates three primary revenue streams: ongoing fractional engagements (typically monthly retainers of $10,000–$30,000), full-time interim placements (monthly retainers of $25,000–$50,000 for roles such as interim COO), and defined-scope strategic consulting projects ($15,000–$150,000+ depending on scope). Pricing varies by executive level, engagement type, and client complexity. Go-to-market is direct enterprise sales targeting founders, CEOs, and portfolio company boards, with the VC/PE fund relationship functioning as a significant referral channel. Named clients include Quantum Metric, DYPER, ShineOn, Rachio, Grove Collaborative, Omaze, Quip, True Footage, Optiversal, and RepairSmith — companies averaging roughly $50M in revenue — and SIZE has supported outcomes including Omaze's $85M Series C, RepairSmith's acquisition by AutoNation, DYPER's inventory reduction from 23.3 to 16.4 weeks of supply, and Quip's 98% fill rates.

Operational reach is concentrated in the United States, with the firm reportedly headquartered in New York and serving domestic venture and PE-backed companies. SIZE complements its in-house bench with delivery partnerships including Crafted Communications (public relations), CO/STUDIOS (brand platform development), Inflection Growth (digital marketing organization building), and Rainbow CFO (startup finance specialization), and cites 800+ cumulative strategic introductions connecting clients to enterprise buyers at brands such as Expedia, Costco, Kendra Scott, and Office Depot.
