Martin Ringlein has spent more than two decades at the intersection of design, technology, and entrepreneurship, but his latest venture, Agree.com, reflects a more personal throughline: simplifying the way people formalize trust in a digital world.
Trained in computer science at the University of Maryland and later at Columbia Business School, Ringlein started his career as a designer and front-end developer. That early focus on user experience would go on to define his approach as a founder building products that remove friction from complex processes.
His entrepreneurial journey began with nclud, a digital design agency that was acquired by Twitter ahead of its IPO. At Twitter, Ringlein helped build and lead the company's research and design organization during a period of hypergrowth. But even as he moved through high-profile roles, including serving as a Presidential Innovation Fellow under Barack Obama, he remained drawn to early-stage problem solving.
"I've always been interested in the moments where systems break down for people," Ringlein has said in past interviews. "That's where design can have the biggest impact."
That philosophy carried into his next company, nvite, a ticketing and payments platform acquired by Eventbrite. There, he worked on product innovation and monetization at scale, gaining deeper exposure to how payments and user workflows intersect.
Now, with Agree.com, Ringlein is returning to a familiar challenge making complicated processes feel simple.
Agree.com is designed as an all-in-one platform for creating, signing and executing agreements, with payments built directly into the workflow. Instead of using separate tools for contracts, invoicing and payments, users can handle everything in a single flow from drafting terms to receiving funds.
The platform targets freelancers, startups and businesses that regularly manage agreements but lack streamlined infrastructure. Features include customizable contract templates, embedded payment options, automated execution tracking and integrations with existing business tools. The goal is to reduce administrative overhead while increasing transparency and speed.
"Agreements are at the core of how business gets done, but the tools around them haven't evolved in a cohesive way," Ringlein said in a company statement. "We're building something that reflects how people actually work today."
The company recently raised $7.2 million in seed funding, following a $3 million pre-seed round in 2024. The new capital will be used to expand the product, enhance security and grow the team.
Beyond product development, Ringlein's broader perspective continues to shape the company's direction. Having advised major organizations including Apple, Amazon, Oracle and The Washington Post, and invested in startups like Chime and SpaceX, he brings both operator and investor insight into building scalable platforms.
His current work also reflects a long-standing interest in emerging technologies such as artificial intelligence and decentralized systems areas he believes will further transform how agreements are created and enforced.
Alongside his professional efforts, Ringlein teaches product design and innovation strategy, often emphasizing the importance of combining historical perspective with forward-looking thinking.
With Agree.com, that philosophy is materializing in a practical way: rethinking one of the oldest business primitives: the agreement for a digital-first, integrated future.
