Monique Deziel is a CPA and Chief Operating Officer at 437, a Toronto-based D2C activewear brand. She joined 437 in 2021 as Business Manager — stepping into a company with no in-house finance function — and was promoted to COO in 2023. Over nearly five years she has led the brand through multiple business seasons: layoffs, restructuring, cost resets, and renewed growth. Before 437, Monique trained at Deloitte Canada in audit and then moved to INFOR Financial Group, a boutique investment bank, where she worked closely with the CFO on internal finance and operations. That combination of public accounting rigour and close-to-the-business execution is the foundation she brings to every engagement. Her expertise sits at the intersection of finance and operations — building accounting foundations, tightening cost structures, designing cross-functional systems, and helping teams scale without breaking. She has hands-on experience in the realities of fashion and apparel: inventory complexity, margin pressure, seasonal planning, and organizational design for lean teams. Monique is a roundtable speaker at Monday Girl and has done informal advisory work with founders and brands outside 437. Her mentoring style is practical and direct — no frameworks for the sake of frameworks, just clear thinking from someone who has run the business. Book a call with Monique to: 1. Audit and tighten your D2C operations as revenue grows 2. Build or repair the financial foundation your brand is missing 3. Work through a restructuring, cost reset, or post-overspend rebuild 4. Design systems and team structure that scale past the founder-does-everything stage 5. Get a clear-eyed operator's take on your growth plan
