With over twenty years of experience partnering with bootstrapped founders, Mainsail Partners has established itself as a leading growth equity firm specializing in helping B2B software companies scale and achieve sustainable growth. The firm’s collaborative and hands-on approach is anchored by Mainsail’s Operations Team, comprised of individuals who work beside founders and management teams to navigate the opportunities and challenges in the critical growth stage between $5 million and $50+ million of recurring revenue. The mission of this team is to help portfolio companies recruit key executives, accelerate product development, scale go-to-market, and build out critical systems and data infrastructure to support growth.  

Mainsail focuses on B2B software companies with a concentration in vertical SaaS, financial technology, healthcare IT, infrastructure and security software, and select horizontal SaaS. Many of these companies provide the core business management software for customers, which is often mission-critical for running their business. This presents an opportunity to build a suite of complementary products to enhance the core software application, aiming to deliver more value to end customers and drive growth for portfolio companies.   

In addition to Mainsail’s Operations Team, the firm supports portfolio companies with a team of investment professionals and a robust database of bootstrapped software companies to support M&A. This team helps to source, fund, and execute strategic add-ons to complement organic growth.   

Since 2003, Mainsail has raised over $2.2 billion and has invested in more than 70 companies. The firm has offices in both Austin and San Francisco.

We have been fortunate to partner with Alex Allemann and his team at Winstead on complex legal transactions. Their depth of expertise, responsiveness, professionalism, and ability to balance legal risk with our business objectives have made Winstead a valuable partner to Mainsail and its portfolio companies.”
