Über PLAUSITY

Plausity was founded to rebuild the operational layer of due diligence. For decades, deal teams across private equity, venture capital, and M&A have spent weeks on manual work that never required their judgment: reformatting tables, re-keying contract terms, reconciling customer lists, stitching together findings across five disconnected tools.

That work was tolerated because there was no alternative. Today there is. Plausity is an AI-native platform that automates the full DD workflow in a single workspace, from data room ingestion to investment-ready reports. The bottleneck was never expertise. It was infrastructure.

Headquartered in Hamburg, Plausity serves PE and VC deal teams, M&A advisors, investment banks, and management teams preparing for buy-side or sell-side transactions across Europe and North America. The long-term vision is to make source-traced, cross-referenced, real-time due diligence the professional standard across every deal, in every jurisdiction, at every scale.

Über das Produkt

Plausity automates the full due diligence workflow in a single workspace. 12 DD workstreams run in parallel: Commercial, Financial, Legal, Tax, Organisation and Compliance, Tech, Cybersecurity, ESG, Value Creation, Industry Expertise, Website Legal Compliance, and Website Technology Compliance.

What sets Plausity apart is source-traceability. Every finding in every report links back to the exact document, page, and paragraph it was drawn from. No more trusting a chain of analysts. Partners can click through to the underlying clause, read it, and form an independent view in the room.

Key capabilities include AI Expert Interviews (voice agents conducting hundreds of parallel conversations in 40+ languages), six custom workflows (IC Materials Generation, Firm-Wide Intelligence Search, Target Sourcing and Screening, Comparable and Precedent Analysis, Legal Document Intelligence, Automated Portfolio Reporting), and native integrations with FactSet, PitchBook, S&P Capital IQ, Bloomberg, and DealCloud.

Weeks of manual work become hours. Reports are built from actual findings, ranked by materiality, not assembled from templates.

Plausity was founded by Sebastian Johnston, a Hamburg-based investor and entrepreneur with nearly 20 years of experience across venture capital and operating roles. Sebastian is Co-Founding General Partner of La Famiglia (now part of General Catalyst) and Venture Partner at Armira Growth, and previously founded Regiondo and VIVERE. He holds an MBA from WHU, with additional studies at Harvard and ITAM.

After running due diligence on hundreds of deals as an investor and advisory board member, Sebastian built Plausity to solve a problem he had lived firsthand: senior judgment buried under operational work that never required it. The team is based in Hamburg, combining deep deal-making experience with AI engineering.
