Yes, while San Diego is known for life sciences, it has a growing software ecosystem. Firms like Harpoon focus on enterprise software, and many generalist funds are open to strong SaaS models, so you can find a good fit.

What is the best way to approach venture capital firms for startups?

A warm introduction from a trusted contact in an investor's network is most effective. Research the firm's partners and portfolio to find a mutual connection. Cold outreach can work but generally has a much lower success rate.

What should my pitch include for early-stage VC firms in San Diego?

What should I do after securing venture capital financing?

After closing your round, it's critical to manage your new capital effectively. This includes setting up proper financial controls, managing burn rate, and deploying funds toward the growth milestones you outlined in your pitch.
