Iolar Ventures is an artisanal venture capital firm.

Our investing model and hands-on approach are based on more than a decade of investing success with a diverse group of entrepreneurs.

About Us

We’re Passionate About Building Enduring Relationships and Helping Founders Achieve Their Vision

New tools and technologies are enabling founders to build startups in a more streamlined manner than ever before. Yet the approach of mainstream venture, with an emphasis on outlier outcomes, rapid growth at all costs, high burn rates, and a large portfolio to mitigate high risk, may not always be the best choice for founders. At Iolar Ventures, we believe there is a better way to align investors and founders. We strive to deliver not just capital but the critical resources that create real impact for a company. 

Our Approach

Capital Efficiency: A Better Way to Build a Company

We believe that the capital-efficient approach is a better way to build a successful company. Iolar Ventures offers our portfolio companies world-class venture capital expertise while enabling founders and teams to start lean and stay lean all the way through their growth journey. Everything we do centers around enabling great outcomes for our founders, and we have crafted an investment approach that uniquely serves the needs of capital-efficient companies. In particular, we believe that:

We value clarity, simplicity, and focus. Amazing things can happen when we stay focused on what is essential. And – as every entrepreneur knows – nothing takes more discipline than focus.

We have purposefully kept our funds small in order to match the needs of our entrepreneurs. That way we don’t need to force companies to take excess capital in order to “move the needle” on returns to our funds. Like our companies, we can then remain highly focused on resourcefulness and delivering a great value proposition.

Our vision

The “First Principles” of our Investing Philosophy

Everyone around the table wins

We focus on aligning the interests of both founders and investors to yield better results for everyone. Our philosophy is that everyone who helps create value should share in the winnings.

Capital efficiency is the key to success

We encourage our companies to stay as lean and streamlined as possible. We believe that capital efficiency is a key contributor to reaching early profitability, which enables a company to control its own destiny.

Choosing to invest in quality over quantity

We’re a boutique firm and plan to stay that way so we can continue to deliver intense focus, value, time, and expertise to our portfolio companies. We cultivate partnerships with founders that last for years, and across multiple companies, in order to deliver value and impact for all our stakeholders.

Deep experience in early-stage investing & entrepreneurship

We have deep experience in all the facets of bringing early-stage technology products and solutions to market, and in building sustainable, profitable businesses. We understand the unique challenges that entrepreneurs face, and are here to help founders excel and succeed.

Investment Criteria

Most importantly, we look for opportunities where we can squarely align with the founders in a meaningful, trusted, long-term relationship.
