Mainsail Partners Raises
$915 Million Fund VI


Oversubscribed fund seeks to continue the firm’s strategy of investing in rapidly growing, bootstrapped software companies

AUSTIN and SAN FRANCISCO (April 19, 2022) – Mainsail Partners, a growth equity firm that seeks to invest in rapidly growing, bootstrapped software companies, announced it has raised $915 million in limited partner capital commitments for its sixth fund, the largest in the firm’s 19-year history. The new fund, Mainsail Partners VI, L.P., was oversubscribed and closed in less than three months, bringing the total capital commitments raised by the firm to more than $2.2 billion.

Mainsail seeks to continue its strategy of targeting $30 to $60 million investments in rapidly growing, founder-led software companies and providing significant operational support to help them scale.

“We are grateful for the support of our existing investors and excited to welcome new investors into the Mainsail family,” said Gavin Turner, Managing Partner and co-founder of Mainsail Partners. “Last year was the most active in Mainsail’s history in terms of the number of new investments and portfolio companies that were acquired or went public.  We believe this momentum is validation of our approach to partnering with bootstrapped founders and providing hands-on operational support to help their companies scale fast and efficiently.”

Since 2003, Mainsail has invested in more than 60 bootstrapped companies and has built an in-house team intended to help software companies efficiently accelerate growth. Mainsail’s Operations Team is comprised of experienced technology operators who work closely with management teams to help them recruit executive talent, optimize go-to-market strategies, launch new products, enhance customer experience organizations and establish strong data systems.

Mainsail has extensive experience investing in software companies that we believe have the potential to be category leaders. Recent investments include Apptega, ServiceCore, Inspect Point, Boostlingo, JobNimbus, PlanHub, Syncro and SourceScrub. Two previously announced investments are the first of the firm’s sixth fund: Centerbase, a software platform for law firms, and Flight Schedule Pro, a software provider for the aviation industry.

“The primary reason we chose Mainsail as our partner was for their experience investing in and scaling software companies like Boostlingo,” said Bryan Forrester, co-founder and CEO of Boostlingo.  “In a short period of time, they’ve exceeded our expectations, helping us to hire key executives, completing multiple add-on acquisitions and supporting our team in optimizing go-to-market operations.”

Since completing its last fundraise in 2020, the firm has promoted three new Partners, opened an office in Austin and bolstered its Operations Team with six new hires, including a CTO and COO.
