Finding Angel Investors and Advisors
What Works, What Doesn’t, and What Angels Look For
Finding the right set of angel investors can be challenging. It is particularly tough to find a single, reliable source to identify successful founders actively investing as angels and offering hands-on mentorship.
Years ago, AngelList was the go-to platform, offering powerful search capabilities and ranked funding activity. As I’ve worked to expand my advisor network, I’ve tested several alternative platforms. Below is a breakdown of the top options, what works, what doesn't, and what research says about pitching them.
My Search Criteria Example: Based in Boston, targeting Enterprise B2B Software in Financial Services.
Top Platforms for Sourcing Angel Groups & Active Investors
Angel Capital Association (ACA)
-
Best for: Locating verified, regional Angel Groups.
-
The Good: ACA applies a vetting process to listed groups, making it a reliable starting point to confirm legitimate organizations.
-
The Drawback: It does not allow you to drill down into individual angel profiles or specific past check sizes.
Gust
-
Best for: High-level investor activity search without requiring a login
-
The Good: Displays general details on check sizes and recent platform activity.
-
The Drawback: Search results cannot be filtered down to the individual angel level, nor do they detail total dollars invested or specific deal counts.
Platforms Fell Short
-
AngelList (Legacy Search): AngelList previously allowed users to filter and sort investors by total deal count, making it easy to prioritize active angels. The original directory URL (angel.co/b2b/investors) now returns a 404 error, leaving me looking for workarounds.
-
NFX Signal: While Signal holds a robust investor database, its geotargeting indexes where portfolio companies are located rather than where the investor actually resides. For a Boston-focused search, top results often live elsewhere.
-

-
Angel Investment Network: Search filters are severely limited; location filtering for specific cities like Boston often fails to produce accurate results.
-
TheFunded.com & Seed-DB (Defunct): Adeo Ressi’s TheFunded (investor ratings) and Jed Christiansen’s Seed-DB (accelerator and seed investor analytics) were valuable free tools, but both have shut down.
Equity Crowdfunding Portals: Searching Beyond Accredited Angels
Wefunder
-
Overview: Primarily a Title III Reg CF portal for non-accredited investors, Wefunder lets you track early-stage trends and active deal backers.
-
Deal Flow Growth: A category search for active B2B companies raising money
-
Investor Visibility: While Wefunder displays notable lead backers on deal pages (e.g., prominent angels like Sahil Lavingia or Garry Tan on rounds like BackerKit), it limits visibility into the thousands of individual non-accredited backers participating in each round.
Advanced Analytics for Check Sizes
For granular data on deal terms, check sizes, valuation benchmarks, and sector-specific performance, enterprise analytics platforms like PitchBook and CB Insights. These have a cost but can be used to identify check sizes and funding amounts in a category with much greater detail on performance.
What Angel Investors Look For
Once you’ve built your prospect list, preparing your pitch requires understanding investor motivations. Research from Propel(x) conducted in partnership with Breakout Labs, Innovation Node - Los Angeles, and MIT Alumni Angels of Northern California (Unfollow the Leader study)—highlights key decision drivers:
-
Management Team: Three-quarters of angel investors rank the founding team as their single most important investment criterion.
-
Solving Meaningful Problems: While 49% prioritize financial returns, nearly one-third invest primarily to back breakthrough technologies tackling major global challenges.
-
Domain Simplicity & Familiarity: Over half of surveyed angels pass on technologies they do not understand. If your core infrastructure or market model is overly complex, simplify the narrative before pitching.
-
Core Campaign Factors: I believe success hinges on three main execution pillars: choosing the right platform, refining your pitch, and securing a strong lead investor.
Key Takeaways for Founders
Focus your outreach on angels who have direct operational experience in your domain, keep your technical pitch accessible, and highlight your team's execution history above all else.
