StructureFlow, a London company whose platform enables visual modeling of complex corporate transactions, has raised $3.5 million in a pre-Series A funding round.

The company, launched in 2019, said it will use the funding to accelerate development of its visual modeling platform and to boost its sales and marketing efforts, with a particular focus on expansion in North America.

The funding round was led by UK-based venture capital firm Venrex, with participation by angel investors Chris Adelsbach and Tariq Khan. The round brings the company’s total seed funding to $8 million.

StructureFlow’s software is already used by some of the world’s largest and most prestigious law firms, including three of the five UK ‘Magic Circle’ firms and a number of Am Law 100 US firms, the company said.

The software enables real-time collaboration around complex corporate transactions, including brainstorming deal structures, designing steps plans, and mapping transactions and disputes.

By visually modeling transactions and bringing the distinct but interconnected elements together, the company says, its platform enables deeper understanding of the complexities of deals across a variety of stakeholders.

“We are thrilled to have secured significant funding in an extremely challenging environment,” Tim Follett, founder and CEO of StructureFlow, said in a statement. “Strong traction and our strength of vision have attracted forward-thinking investors. We will not rest until we have transformed the way people work on complex deals — moving the industry away from dense text to more visual ways of working.”

In 2020, the company participated in Fuse, the tech incubation program of law firm Allen & Overy. Of this investment, Shruti Ajitsaria, Allen & Overy partner and head of Fuse, said, “So pleased about StructureFlow’s successful fundraise. We very much enjoyed having the team in Fuse, our tech incubation space, in 2020 and have been delighted to support and use StructureFlow since then. I am looking forward to seeing where their journey takes them next.”
