Pioneering a new way to prevent fraud on the

Online fraud prevention has centered around community-powered blacklists for years. For a site to get on the list, a human had to look at it. As the internet and the scam sites on it continue to grow, we don’t think that human intervention is scalable.

We built a suite of computer vision, natural language processing, and deep learning models to mimic how a person looks at and categorizes a page. With 100ms verdicts and 1/100,000 false positives, our AI is faster and more accurate than a human.

With a focus on intelligent infrastructure, scalable deep learning, and elegant design, we constantly innovate on our technology – making it more accessible for engineers, easier to use for operations teams, and more extensible for the future of online fraud.

We’re working towards a safe internet for all.

It’s not just your favorite brands, who are targeted by fraud and phishing. Charities, non-profits, social benefit corporations, and schools are often targets as well. These organizations don’t always have the resources to combat scammers at scale.

To aid the world in the fight against online fraud, we will give our technology and services for-free or at-cost to any approved charity, non-profit, or social benefit corporations.

We’re working towards a carbon-neutral future.

Our office is almost entirely powered by renewable energy. But we know that isn’t enough to offset our carbon footprint. Commuting to work, traveling, and even lunch contribute to CO2 emissions.

As such, we commit to sequestering 16 tons of CO2 per employee / year. (# of tons that the average American produces in a year).

To achieve this goal, we plant 333 trees every time an employee joins Bolster.
