Stillmark Empowering Groundbreakers
Break the mold build the future

Stillmark invests early - Pre-seed, Seed, and Series A stage - to partner with intrepid founders building the next generation of market defining companies.

Founded in 2019 as the first Bitcoin-focused venture capital firm, Stillmark invests in, advocates for, and supports the vision of entrepreneurs whose plans, products, and technologies advance Bitcoin’s core principles and the opportunities inherent and unique to the tech. We’re at work for a new era.

About Founding Partner Alyse Killeen

about

BOLD PERSPECTIVE

While we are, by definition, a “traditional” venture capital firm, the work we do and the people we work with call us to challenge, and often defy, traditional views — to find purpose in being the first to back an innovative idea or company — to be a bellwether of the ecosystem by continually seeking out fresh perspectives, embracing emerging technology, and partnering with entrepreneurs who push the boundaries of what’s possible.

STUDIED APPROACH

We feed our passion for the industry by consistently working to study and understand it. That means we're rigorous in our research — reviewing public pools of information, and thanks to our robust network, immersing ourselves in proprietary data across the full stack of infrastructure and breadth of the ecosystem — to put it all to work for our founders and investors.

TRUSTWORTHY PARTNERSHIP

Every founder and team member we work with has something on the line — a vision, a reputation, their hard work. Our responsibility is to honor that with our support, our insight, and our advocacy — to do what we say we're going to do, and together build enduring, market changing businesses.

COMMUNITY CONNECTED

We are connectors motivated by the transformative power of relationships. As one of the first investors in the Bitcoin community, we've built a best-in-class network of the brightest minds in the field — founders, investors, engineers, and operators — and we’ve seen firsthand what’s possible when people from different teams, or diverse disciplines and walks of life, come together.

THE NUTS AND BOLTS

Stillmark is an early stage VC firm investing out of our first fund.

Our initial capital commitment is typically between $250,000 and $750,000 but can be adjusted up or down to fit the dynamics of your financing. We’ll often invest additional capital in subsequent financings and when we invest, we commit to be your partner for the long term - through both the good times and the bad.

We have a depth of venture experience and have worked with hundreds of founders over the years. That means that we know there will be kinks (or more) to work out along your entrepreneurial journey and we aren’t scared to hear the gory details. We’re here to back you up.

We roll up our sleeves alongside you when doing so can help accelerate growth, knock down roadblocks, or smooth out a challenge. We’ll leverage our network for your benefit, including to help you fill a financing round with the best, most useful investors in the field.

It’s never too early to reach out to Stillmark - there’s no need to wait to have your pitch perfected or to be in fundraising mode. We often connect before a new founder has left their last post or incorporated their new company. However - occasionally we’re late. If Stillmark missed your last round, reach out to get to know us before your next one.
