How would you value this? I will not promote

How to value a LogisticTech startup with strong growth and retention metrics? I will not promote I'm a first-time founder of a B2C LogisticTech startup seeking our first funding round. I'd appreciate your input on valuation based on these metrics: • 3-year-old US company with proven MVP • Explosive growth: Spent year one finding our niche, achieved 600% ARR growth in year two, followed by 250% in year three • Outstanding retention: 82% of users still active after 12 months • Healthy 40% margins after all costs • $4M ARR last year, targeting $10M this year (250% growth) • Fully in-house tech stack with increasing AI automation • Customer acquisition through paid ads and referrals • We have a strong brand with ~0.5m Following on social media and our users use our own app so we might also have a network effect We've bootstrapped until now, reinvesting profits for growth, but we're ready to accelerate with VC funding. What would be a reasonable ARR multiple or valuation given these metrics? I have initial investor meetings scheduled in the coming weeks and want to be well-prepared. Thank you all for your feedback.
