Thesis-Driven vs. Opportunistic Investing: A Sourcing Perspective

The debate between thesis-driven and opportunistic investing is as old as venture capital itself. From a sourcing perspective, the answer is clear: thesis-driven funds have a structural advantage that compounds over time.

The Thesis Advantage

A thesis-driven fund has a clear answer to the question: "What are you looking for?" This clarity creates three sourcing advantages:

1. Signal specificity. When you know you invest in B2B infrastructure at Series A, you can define exactly which signals matter: engineering hiring velocity, enterprise customer adoption, developer community engagement. An opportunistic fund that invests in "great companies" has no way to systematically filter signals.

2. Network depth. Thesis-driven funds build deep expertise in specific sectors. Their partners speak at the right conferences, know the right operators, and understand the competitive landscape. This expertise makes them better at evaluating signals when they fire.

3. Pattern recognition. After investing in 20 developer tools companies, you develop pattern recognition that an opportunistic investor lacks. You know what good hiring velocity looks like in that sector. You know which customer logos are meaningful. You know which press mentions matter.

Why Signal-Based Sourcing Amplifies Thesis-Driven Investing

Signal monitoring is inherently thesis-driven. You define the thesis, set signal weights, and receive scored companies that match your specific investment approach. This creates a feedback loop:

• Your thesis defines which signals to monitor
• Signals surface companies that match your thesis
• Company interactions refine your thesis
• The refined thesis improves signal monitoring

For opportunistic funds, signal-based sourcing is less effective because there is no thesis to score against. You end up with a fire hose of data instead of a curated feed.

The Hybrid Approach

The most sophisticated funds use a thesis-driven core with opportunistic edges. They maintain 2-3 primary theses with active signal monitoring, while staying open to exceptional opportunities outside their core focus.

Ted supports this by allowing multiple thesis configurations, each with its own signal weights and scoring model. Your primary thesis might weight hiring velocity heavily, while your secondary thesis might prioritize funding activity.

Making Thesis-Driven Work at Scale

The practical challenge of thesis-driven investing is that deep expertise is hard to scale. A single partner can maintain expertise in 2-3 sectors at most. Signal-based sourcing solves this by doing the systematic monitoring work that would otherwise require sector analysts.

The partner provides the thesis and the judgment. Ted provides the signal monitoring, scoring, and daily delivery. The combination gives small funds the sourcing capabilities that used to require large teams.
