Frequently Asked Questions
You’re ready when financial decisions feel heavier than they should. If you’re guessing instead of forecasting, reacting instead of planning, or carrying the entire financial model in your head, it’s time. Our CFO Assessment helps you see exactly where you stand and whether a Fractional CFO will move the needle.
We give founders and operators visibility, insight, and control. That means improving reporting, demystifying financial statements, building tools that guide decisions, and translating numbers into narratives that help you move with confidence. When you understand what’s true and what’s possible, growth becomes intentional.
Think of it like a multilap track race.
-
Lap 1 (6-8 weeks): Clean reporting, reliable numbers, trust in the back office.
-
Lap 2 (8-12 weeks): Tools that drive insight and help you take calculated risks.
-
Lap 3 (90–180 days): Fundraising, growth initiatives, and strategic clarity.
-
Lap 4 (12–24 months): A meaningful lift in cash flow and operational efficiency.

Stuart Bernstein was an operator before a finance professional. He’s sat in startup, SMB, and enterprise seats before transitioning into finance, which means he understands how decisions ripple across the business. By bringing a mix of data
science, storytelling, and real world judgment, he helps founders and teams move faster with more clarity.Helpful, but not decisive. Most businesses fall into a handful of underlying models: SaaS, services, marketplaces, product companies. Solve For (X) studied the models, then the industries. That’s how we’ve been able to help clients across 55 industries without needing a six-month onboarding period.
Absolutely. Solve For (X) has helped nearly 300 startups and small businesses refine pitch decks, build investorgrade financial models, craft business plans, and prepare for diligence. We can also help shape the narrative, anticipate investor questions, and role-play pitches so you present with confidence and secure more capital.
Platforms are great until you need continuity, judgment, or someone who deeply understands your business. Stuart Bernstein works directly with founders and operators, rolling up his sleeves, and staying engaged. You’re not getting a rotating cast; you’re getting a partner.
Yes! I can prove it in 20 minutes. The difference becomes obvious fast.
