Build an Investor Outreach List
Find venture capital firms and angel investors that match your stage, sector, and geography for a fundraising campaign.
Research Investor Portfolio Fit
Evaluate which investors are most aligned with your company by analyzing their investment focus and portfolio patterns.
Quick answer: Use the Investor Finder tool through ToolRouter to research investor portfolio fit directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolSending a cold email to a VC who has never touched your category is a waste of everyone's time. The best fundraising outreach targets investors where there is a clear thesis fit — they have backed similar companies, their stated focus matches your sector, and their current portfolio does not include a direct competitor.
The build_outreach_list skill surfaces investors filtered by stage and sector, giving you a starting point for portfolio analysis. You can identify the investors who have already demonstrated conviction in your space and prioritise them for warm outreach through shared connections.
Founders doing pre-fundraise research, advisors helping portfolio companies prepare for their next round, and accelerators building investor relationships all use this to move from a long list of possible investors to a short list of probable fits.
How to research investor portfolio fit with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude investigates investor-company fit through a multi-step research conversation. Build an initial list by sector and stage, then ask Claude to assess fit signals — which investors have the most relevant portfolio history, who has a stated thesis that matches your positioning, and who you should prioritise for warm outreach versus cold email.

My company is a Series A B2B marketplace for construction materials in Europe. Use investor-finder to find VCs and growth investors who have backed B2B marketplaces, construction tech, or industrial supply chain companies at Series A in Europe. Rank them by portfolio fit and tell me which to prioritise for warm outreach.
Tips for Claude
- Frame your company description in terms of category, business model, and customer type to improve fit matching
- Ask Claude to flag investors who have backed direct competitors — thesis fit is high but conflict risk exists
- Prioritise investors where you can identify a portfolio company connection for a warm introduction
ChatGPT formats investor fit research into a prioritised outreach brief. Build the list, then ask ChatGPT to rank investors by apparent thesis alignment and format the output as a tiered outreach plan with reasoning for each priority.

My company is a seed-stage AI-powered legal tech platform targeting SMBs in the UK. Use investor-finder to find investors in legal tech, B2B SaaS, and AI at seed stage. Rank them by thesis fit and produce a tiered outreach plan: Tier 1 for warm outreach, Tier 2 for targeted cold, Tier 3 to watch.
Tips for ChatGPT
- Ask for a tiered output so you can sequence outreach rather than approaching everyone simultaneously
- Ask ChatGPT to write a one-line personalisation hook for each Tier 1 investor based on their apparent thesis
- Request reasoning for each tier ranking so you can explain the prioritisation to your co-founder or advisor
