Hi, we’re Character.

A new seed fund supporting founders with capital and sprints.

When you’re just starting out, we believe there’s nothing more important than building the right product for the right people. We helped Flatiron Health, Digit, Blue Bottle Coffee, and Slack figure it out fast — and we can help you, too.

⚡️ Character Labs is our sprint program for pre-seed AI founders. Learn more →

Our startup advisors are Jeanette Mellinger, Charles Adler, and David Cirilli.

We are backed by more than 100 LPs, who act as an extended team to help us find and support startups. Our LPs include founders and executives from YouTube, Google, Slack, Square, Uber, Mozilla, Gusto, Clubhouse, Coinbase, Flatiron Health, and many other technology companies.

Seed Capital

We invest early and amplify our support as you build your company.

Investing up to $2 million at seed stage

We invest flexibly across the spectrum of seed stage, including Character Labs, our sprint program for pre-seed founders.

Focused on startups with technical edge and behavioral insight

Especially in AI/ML, enterprise, industry, climate, healthcare, and the life sciences — where software can unlock meaningful behavior changes that are aligned with customer goals.

Located anywhere — or everywhere

Great founders know how to leverage remote work to build amazing teams, and when to gather the team to sprint and connect. We’re a remote-native firm investing in companies incorporated in the USA.

Design Sprints and more

We work hand-in-hand with your team, using the Sprint method we created at GV, to help you find and expand product-market fit.

Answering high-stakes questions

Which customers should you focus on? How should the product look? What should you build next? Early-stage startups need to answer these questions ASAP, and we can help.

Together with your team

We’re not just talking about playbooks and resources — we actually clear our calendars and sprint with your team. Ask any founder we've worked with.

A proven recipe for startups

We've used sprints to help more than 200 startups answer questions and validate hypotheses. Thousands more have read our book and embraced the process. It works.

About Character

We exist to help founders like you build the right product for the right people. We invest capital and time to help you figure it out fast.

But it’s not just about technology and money. For us, it’s personal, because time is our only finite resource. An hour spent at work is an hour we can’t spend with family or friends, or taking care of ourselves or our communities.

We believe the best use of our time is helping you build products and services that create meaningful change for your customers. Let’s work together to make it count.

We’d love to learn about what you’re building.
