Specter quickly became the go-to platform
for modern data-driven investors.

Get started

There are very few must have tools for me. The visibility and insight that Specter allows me is second to none and simply could not live without it these days.

Now we spend far less time on infrastructure and spend more of our time building those relationships and investing behind the best founders in our ecosystems. I think Specter will become table stakes for any fund that wants to be in the top quartile.

In a short period of time, Specter has become an integral part of how we ensure we have 100% coverage of the markets we operate in.

We are embedding Specter into all our workstreams, and it is showing significant promise as part of our strategy to find the next company we will back.

Specter enhances the efficiency of our operations, and contributes to the in-house data systems we build to generate alpha. Covering both bases makes it a highly versatile and valued part of our tech stack.

Specter allows me to narrow or expand the scope of searches at will, without needing to build or maintain any of the data pipelines and infrastructure myself. Using it on a daily basis is super powerful.

We've already found one of our investments through Specter! That being said, its value extends beyond pure sourcing. Signals provide a level of intelligence that's valuable throughout the entire investment lifecycle.

Specter's performance-based signals draw us towards the right startups at the right time, so we're prepared as we can be to make the right decision.

We've invested in a founder with roots at Stanford and Wharton. They were a rising star in their industry with a strong technical background. We found them as a Stealth signal through Specter.

Tools like Specter surface early talent signals, company foundations, team moves, and nascent traction, beyond what internal scouts can manually track. We see companies we wouldn't see otherwise.
