There's no definitive minimum potential value that a startup needs to attract VC funding, as VCs evaluate many qualitative factors beyond just revenue projections. However, here are some general guidelines based on your example:

A market size of $9 million annually could be considered on the smaller side for a Series A. VCs typically want to see a $50 million+ total addressable market.

An annual revenue run rate of less than $1 million would make it difficult to attract VC interest at an early stage, all else being equal. They want demonstrated traction.

Gross margins of over 50% are generally expected to show the business can scale profitably. Your estimated costs of <$500K point to good margins.

estimated 3-5x revenue multiple on exit. So a $9 million revenue company could exit for $27-45 million. This may or may not meet VC return thresholds.

Competitive advantage and barriers to entry are important since the market is smaller. Proprietary technology or a strong moat could offset the size.

Founding team experience is also a factor. First-time entrepreneurs face higher hurdles generally.

Angel/seed funding history shows the ability to hit milestones and de-risk the opportunity.

While your numbers alone may not wow top VC firms, there's a chance an angel or smaller fund could take interest if other qualities like teamwork, tech, and marketing strategy are strong. Hitting $2–3 million+ in annual recurring revenue would make the profile much more VC-friendly.
