As answered by people managing POWr and SQLBolt.
POWr's answer
Many companies make website apps and plugins to improve performance, but none provide them from a single platform. That matters because installing several plugins can dramatically slow your site speed, costing you precious customers. With POWR One, you can use as many plugins as you like and keep your site speed lightning-quick!
POWr's answer
As the saying goes, “We got a lot wrong to get a lot right.” We’ve been helping small businesses succeed online since 2014. Our claim-to-fame is our stellar Customer Success team. They make up over half of our entire staff. Also, POWR Apps can be found on over 13 million websites in 172 host countries, so we know a thing or two about a thing or two. Along the way, we have amassed over 5,000 5-star reviews on 200+ platforms like Wix, WordPress, Shopify, BigCommerce among many others.
POWr's answer
Our core customer is the small business owner or solopreneur that must wear many hats to keep the company moving forward. They typically are not that familiar with web development or coding and don’t have the funds to hire someone who does. POWR One is for someone short on time and cash flow but still must have a website or online store that performs at max capacity.
POWr's answer
We used React and Ruby on Rails to build the product.
POWr's answer
Every business is our biggest customer, and we have over 500,000 worldwide that are equally as important to us. However, you might recognize some, like: Harvard University, Boeing, CrocsUSA, SpaceX, Acer, Nestle, and NASA.
