Slope Secures $30M from Sam Altman and USV to Scale its AI-Powered Payments Platform for B2B Enterprises

Slope, a B2B payments platform for enterprise companies, today announced a $30 million equity round led by Union Square Ventures, with major participation from OpenAI’s Sam Altman, bringing Slope’s combined equity and debt funding to $187 million. Additional participants include monashees, Y Combinator and Y Combinator-backed startups, including Jack Altman from Lattice, Arash Ferdowsi from Dropbox, Stanley Tang from Doordash, Zach Perret from Plaid, Alex Bouaziz from Deel, Mathilde Collin from Front, Michael Tannenbaum from Brex, and Rujul Zaparde from Zip.

Slope offers order-to-cash workflow automation using leading AI tools that power checkout, customer and vendor risk assessment, payment reconciliation, and cash management. The order-to-cash (O2C) workflow is the backbone of Slope’s automated solution for enterprise companies and begins with a customer order and concludes with successful payment collection. Used by leading companies like Fiserv (NYSE: FI), Slope’s AI-driven solutions streamline everything from customer onboarding to invoicing, ensuring seamless execution, accurate transactions, and enhanced customer satisfaction.

“From the beginning, our goal has been to digitize the B2B economy,” said Lawrence Lin Murata, CEO and co-founder of Slope. “We started by leveraging AI to solve risk, the most fundamental problem in payments. Halfway through that journey, we realized that we were not just solving risk – but actually, an entire order-to-cash lifecycle that today is offline, manual, and takes entire finance teams to manage. We believe our tech-first approach – aided by breakthroughs in generative AI – will modernize an industry that’s barely changed for centuries.”

Sam Altman brings extensive AI experience and will advise the team on product and technological development as Slope scales its platform. “Slope’s quest to reshape the B2B payments experience and bring the sector into the digital age is audacious – and that’s why I chose to back them,” said Sam Altman, CEO of OpenAI.

“Slope’s pace of growth has been incredibly impressive and we are very excited to double down and deepen our partnership in this round,” said Rebecca Kaden, General Partner at Union Square Ventures and Slope board member. “They’ve quickly found product-market fit and are becoming leaders in the B2B payments space. We wanted them to be able to aggressively lean in when others in their market were playing defense, and now they are in a unique spot to do so.”

Slope’s round was preempted by an outsider and resulted in multiple lead offers, quickly becoming oversubscribed by 2x. The news comes on the heels of Slope’s recent product launch, SlopeGPT, the first payments risk model powered by GPT, which went viral within the AI community. The company also brought on Ashish Jain, a former SoFi and Wall Street executive, as Chief Financial Officer, spearheading risk and financial operations. Slope co-founders Lawrence Lin Murata and Alice Deng draw from their AI startup backgrounds in autonomous driving, computer vision, and NLP, uniting as former rivals from Stanford and UC Berkeley to build Slope and digitize the $125T B2B economy.
