Platus

Platus is a legal technology company offering what it describes as legal infrastructure delivered as a no-code platform and an API. Its core product concept is AI-driven "Legal Agents" that autonomously perform document-heavy legal tasks such as contract analysis, drafting, redaction of sensitive information, due diligence support and approval routing. The platform is organized around modular "Superapps" that bundle pre-built tools — AI document translation, automated notarization and smart approval flows — together with a customizable Canvas Module that lets customers assemble tailored applications; individual apps can be deployed standalone or integrated across an enterprise via API. Additional platform functions cited at launch include real-time notarization, an e-signature API, workflow automation and AI-powered document analysis.

The company positions its agents as operating within governance frameworks intended to preserve confidentiality and compliance. Its stated ambition is to become the "legal brain" for small and medium-sized enterprises, handling complex legal processes more quickly and at lower cost than traditional document-driven workflows. Platus is associated with the German sub-brand Beglaubigt.de, a platform for digital company formations and notarizations that reduces GmbH incorporations from six to eight weeks to as little as three days, operates Germany's first fully automated incorporation API, and has expanded into registered business addresses with an AI mailroom, trade registrations and bookkeeping.

Founding story

Platus was founded by Alexander Sporenberg and Felix Gerlach, both repeat founders. Sporenberg, who serves as CEO, previously worked on cross-border legal services at Razor Group — where he was on the founding team of a company that scaled to a €1.7B+ valuation, 500+ employees and 150+ acquisitions, and where he oversaw more than 100 M&A deals in which notaries rather than deal terms proved to be the bottleneck — and founded Beglaubigt.de, a platform for digital notary services. Gerlach, CTO and co-founder, was named to Forbes "30 Under 30 Finance" in 2020 and co-founded Passbase Inc., a KYC/AML B2B SaaS company he exited in 2023.

Business model

Platus sells legal automation software to businesses, offering standalone applications for specific tasks and API integration for enterprise-wide deployment, with a modular Superapps and Canvas Module structure that lets customers configure their own tools. Under the Beglaubigt.de brand it also provides transactional legal back-office services such as company formations, notarizations, registered business addresses with digital mail handling, trade registrations and bookkeeping.

Traction

At launch in November 2024 the company reported having acquired international customers and was described as one of the five fastest-growing companies in the Y Combinator Fall 2024 batch. Its incorporation API powers formation flows for partners such as Qonto, Holvi and Sevdesk, and the associated Beglaubigt.de entity reports a team size of 15.

Latest developments

The company announced Superapps, enabling customers to build a legal agent within seconds and deploy it company-wide. Under the Beglaubigt.de brand it launched legally compliant business addresses combined with a fully digital, AI-interpreted mailroom in Hamburg, Berlin and Munich, and said it plans to add more cities and deeper automation toward an autonomous back office. Beglaubigt.de is also recruiting, including an Entrepreneur in Residence internship in Munich with remote US options.
