What is Grindstone?

Grindstone is a London-based consulting service firm that enables e-commerce and technology start-ups to reach their full potential.

Driven by a culture of knowledge, honour and hard work, our team pushes boundaries to help our clients become more efficient and more profitable. The power of our expertise, coupled with an entrepreneurial passion to keep learning, ensures that the strategies we develop are both innovative and well-tested in the marketplace.

For more than 10 years, Grindstone’s mentorship has facilitated the launch of market-leading products in the fields of e-commerce, business automation, digital entertainment, performance marketing and more.

Investment Strategy

We follow a precise and highly-efficient investment strategy.

Grindstone Capital’s primary objective is to be the partner of choice for high-quality, fast-growing companies. Our team works closely with these companies to unlock greater potential. Our expertise has allowed us to launch many successful start-ups, be part of many turnarounds and acquire strategically aligned businesses.

Our carefully tailored strategy improves our companies’ competitive positions by expanding into new products and markets, growing productivity and strengthening their operations. Ultimately, we believe our growth-oriented model results in stronger companies that employ the best people, are socially responsible, and deliver strong returns over the long-term.


We know that a company’s greatest competitive advantage is not its technology or its process – but its people.

We welcome the most ambitious people into our circle and provide them with the tools and knowledge to reach their full potential. As a new member of our society, you’ll be part of a powerful network of entrepreneurs and creative people for life.

Grindstone is always looking to work with the best talent in Montreal, and our global offices. That includes emerging talent looking to get their career off to the best possible start, and established experts in the technology sector.
