To date, Shippo has raised $94 million.</p><p>Shippo's goal is to help small-to-medium sized businesses achieve fast, low-cost shipping by offering application programming interfaces, or APIs, to link together e-commerce firms' various services. <a href="https://www.businessinsider.com/api-companies-twilio-stripe-explosive-growth-2020-11">APIs essentially connect data and features from different apps and tools</a>, allowing them to "talk" to each other; payments firm Stripe and communications platform Twilio are two of the biggest companies in this space. </p><p>Shippo aims to be the "Stripe for shipping," cofounder Laura Behrens Wu told Insider: Its platform helps online stores bill customers for shipping costs, print labels, track packages, handle returns, and more, essentially connecting all online and offline processes.</p><p>"There are real life events that need to happen: A truck needs to pull up at your warehouse. The warehouse workers have to figure out which items are put into what box, put a label on it, give to the right courier," Wu said. "There is an offline component involvedeven though we don't run any warehouses ourselves or ship any packages ourselves, we still need to figure out how to make that work."</p><p>The company now serves more than 70,000 customers, including <a href="https://www.businessinsider.com/goat-raises-100million-hits-1-billion-valuation-sources-say-2020-9">GOAT</a>, him, <a href="https://markets.businessinsider.com/news/stocks/touch-of-modern-named-to-inc-5000-list-of-america-s-fastest-growing-private-companies-for-second-consecutive-year-1002272088">Touch of Modern</a>, and <a href="https://www.businessinsider.com/best-hand-soap">Aesop.</a> Anything that can fit in an average-sized box that Fedex or UPS can deliver easily is fair game for Shippo. </p><p>"Everything you can buy on the internet, we've shipped it," Wu said. "Recently I've seen that there was a store selling crickets for, I guess pets that eat crickets. Anything you can imagine being sold on the internet, I'm sure we've shipped."</p><p>Aside from cricket retailers, Wu said the firm's"bread and butter" is small lifestyle businesses, including fashion, cosmetics, and food companies.</p><p>The firm has seen a spike in use as <a href="https://www.businessinsider.com/half-of-retailers-plan-digital-makeover-amid-e-commerce-boom-2021-1">e-commerce has thrived</a> due to the pandemic: New <a href="https://www.eset.com/us/about/newsroom/press-releases/eset-survey-finds-70-of-americans-are-shopping-more-online-than-before-the-pandemic-yet-only-38-f/'ref=AFC-CJ&attr=100024933&pub=14021947&shop=35871X943606X3741a8e12d1d451facf95a0ccf0694af&utm_source=100024933&utm_medium=affiliate&utm_content=14021947&cjevent=f5a656e4753a11eb832402a70a1c0e0c">data from ESET</a> shows that 70% of Americans are shopping more online than they did before the pandemic. </p><p>"COVID was an accelerant for e-commerce. So more big businesses have been moving online and new businesses that were getting started as online businesses as well. And then all of our existing customers were shipping more than before, because it's changing consumer behavior," Wu said. "All of that was just really good for our main metrics."</p><p>Shippo's existing investors saw the growth and decided to double down, she added. That VC enthusiasm is a far cry from what Wu experienced when the firm originally tried to raise funding. </p><p>"I actually pitched more than a hundred investors to raise our seed round," she said. "I think it took awhile for me to figure out how to pitch, but also it took a while to find the right person who understood the business."</p><p><strong>SEE ALSO: <a href="https://www.businessinsider.com/sentry-60m-seriesd-funding-error-monitoring-software-2021-2" >Sentry just raised $60 million at a $1 billion valuation to help 'every developer write flawless code'</a></strong></p><p><strong>SEE ALSO: <a href="https://www.businessinsider.com/10-most-hiring-programming-languages-2020-according-to-coding-dojo-2021-2" >Top 10 programming languages companies are hiring for in 2021, according to coding bootcamp Coding Dojo</a></strong></p><p><strong>SEE ALSO: <a href="https://www.businessinsider.com/15-best-computer-science-programs-colleges-universities-united-states-2021-2" >The 15 top computer science programs in the United States</a></strong></p><p><a href="https://www.businessinsider.com/shippo-45m-startup-funding-ecommerce-shipping-api-2021-2#comments">Join the conversation about this story »</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/melissa-maker-clean-your-home-quickly-cleaning-expert-2017-4">A cleaning expert reveals her 3-step method for cleaning your entire home quickly</a></p> Click here to read full news..
