You found the opportunity. We assess the risks.
Neuhaus Advisory provides independent, high-signal technical due diligence for venture investors, private equity firms, and strategic acquirers.
Who we serve
Trusted by leading investors for high-stakes tech investments.
What we do
We surface the product & technology risks that actually matter for your investment decision.
We help investors understand whether a company’s technology, product, and team can realistically support the investment thesis — and where hidden risks could impact valuation, timing, or downside.
Can this business scale the way the model assumes?
We assess whether the current architecture, infrastructure, and data foundations can support projected growth — and where scalability, reliability, or performance risks could invalidate growth assumptions.
Can this team actually execute?
We evaluate engineering leadership, team structure, and delivery capability to determine whether the roadmap is realistic — or dependent on key individuals, heroics, or future hires.
What technical risks could change valuation or deal terms?
We surface red flags, dealbreakers, and hidden technical debt that could materially impact valuation, timelines, post-deal costs, or integration feasibility.
How strong is this technology relative to peers?
We benchmark the company’s technology and engineering maturity against comparable businesses to separate genuine advantage from table stakes.
Is the product roadmap technically achievable?
We validate whether the promised roadmap is feasible given the current codebase, architecture, and technical constraints — and where expectations may need to be reset.
What happens after the deal?
For growth investments and acquisitions, we assess integration, security, and operational risks that affect post-deal execution — including infrastructure, data, and security posture.

Previous engagements
From pre-seed rounds to corporate M&A, we deliver fast, reliable, and investor-ready technical DD.
For a Series A investment in a B2B SaaS company, we assessed the scalability of the product and the execution capacity of the engineering team. The review surfaced structural constraints in the architecture and a heavy reliance on one senior engineer for core systems. While not deal-breaking, these risks informed a more conservative growth plan, adjustments to the hiring roadmap, and changes to governance expectations post-investment.
During a growth-stage acquisition process, we conducted technical due diligence focused on data architecture, operational resilience, and long-term maintainability. The analysis revealed fragmented data pipelines and higher-than-expected technical debt in core systems. The deal proceeded, but the findings directly informed downside protection mechanisms, integration planning, and prioritization of post-close technical remediation.
For a corporate acquirer evaluating a technology-led acquisition, we performed a rapid technical diligence to assess integration feasibility and time-to-value. The review identified mismatches between the target’s architecture and the acquirer’s core platform, as well as underdeveloped internal documentation and testing practices. These insights influenced integration sequencing, resourcing assumptions, and the expected timeline for realizing strategic value from the acquisition.
