Technical Due Diligence & Investor Readiness

Choose the technical judgment your investment decision needs, not a promise to close the round: founder-side preparation or a separately commissioned investor-side review.

  • Choose the mandate first
  • Recipient, access and conflicts defined
  • Investment judgment stays with the investor

Our network includes CTOs, engineering leaders,
and technical advisers with experience at and around companies such as:

IBM Stripe UBS Citi Fujitsu Wipro InHealth GSK TransUnion Deloitte J.P. Morgan
SAP NHS Marie Curie BBC Anthropic CMH Clinic SE Health Sartorius Illumina Achilles Therapeutics Prevayl

Signs you need technical due diligence help

It is relevant when there is a working product or prototype, an existing team or vendor, specific technical questions and authority to make evidence available.

  • A founder with investor questions

    You may need help preparing the team to explain its evidence, dependencies and remaining risks.

  • An investor commissioning a review

    You need a separately defined mandate, recipient and access arrangement for your own technical conclusion.

  • An evidence index already exists

    You have an evidence index and proposed milestones but need senior judgment on whether the answers are defensible.

  • Limits that need explaining

    You need to explain what the evidence supports, what is still planned and which risks remain open.

What a technical handoff can make clear

If you commission work from any provider, define acceptance around the agreed contribution and traceable evidence, not investment secured or pages produced.

  1. What was examined

    The relevant product and version, artifacts, sources, access and method, including inspection limits.

  2. What the evidence supports

    Findings separated from assumptions, estimates, third-party statements and untested plans.

  3. What remains open

    Residual risks, disputed facts, missing evidence and accountable owners.

  4. What happens next

    Proposed milestones linked to dependencies, people and cost assumptions; remediation and delivery agreed separately.

  5. Who receives and maintains it

    The intended recipient, usable evidence references, permitted retention and sharing, and the owner of updates.

  6. Detail the mandate may need

    Own and external AI components, manual work and cost dependencies, and artifacts mapped to rights records for legal review.

Who commissions the work and who receives the conclusion

Before selecting a technical due diligence consultant, agree who commissions the work, who receives the conclusion and what decision it supports.

  1. Founder-side preparation

    Helps the founder and technical owner verify responses, expose gaps and explain realistic milestones and risks. It is not automatically an independent investor conclusion.

  2. Investor-side review

    Evaluates agreed technical questions for the commissioning investor, within permitted access and explicit scope, with its own authority, recipients, disclosure terms and conflicts.

  3. The founder and the investor

    The founder remains responsible for the company's statements. The investor or their reviewer decides whether the response is sufficient.

  4. Other advisers

    A fundraising adviser may own transaction preparation, while legal counsel handles legal rights. Neither role should be silently assigned to a technical adviser.

From the mandate to an accepted handoff

  1. Write down the mandate

    The commissioning party, intended recipient, technical questions, required personal experience, access limits, conflicts and acceptance responsibility.

  2. Name the job

    Preparation, review or separately scoped delivery. Do not let one label conceal three different jobs.

  3. Talk with the curator

    Bring a non-confidential account of the decision, your role and the contribution you need, and ask whether an upcoming session fits.

  4. Check the person's contribution

    Ask what they personally inspected, decided and communicated in a comparable situation, and how conflicts were handled.

  5. Agree the work in writing

    Put separately commissioned work in an agreement: scope, access, deliverables and recipient. Implementation is agreed separately.

Example: an investor asks who can explain manual onboarding

Told in three steps: the situation, the questions to settle first and what to take from it.

The situation

A founder has an evidence index and a proposed next-customer milestone. The investor asks who can explain the dependence on manual onboarding and whether the resource assumptions are credible.

What to settle before appointing anyone

  • Does the founder need preparation, or does the investor want its own technical conclusion?
  • Can the engineering lead and existing vendor already explain the evidence adequately?
  • If the investor wants its own conclusion, who reviews, for which recipient and with what access?

What to take from it

An adviser who helped prepare the response should not simply relabel it an independent investor review. The founder remains responsible for the company's statements.

What we believe

We work best with founders who believe in what they are building

Every founder brings a different challenge. What stays the same is how we approach it.

Grand Rounds video session: David Carroll with CTOs Neil Catton and Edoardo Turelli, and curator Jane Vyshnova
David Carroll Founder of Euryan David came to Grand Rounds with two open questions he wanted pressure-tested before taking them to investors: how Euryan should handle LLM and cloud strategy across different client environments, and whether the core product wedge, dynamic FMEA/8D automation, was the right foundation to build the rest of the roadmap on.
Grand Rounds video session: Susie Williams with CTOs Neil Catton and Jerome MacGillivray, and curator Jane Vyshnova
Susie Williams Founder of LinkEDtohome Susie came to Grand Rounds with two questions she wanted pressure-tested before LinkEDtohome moved beyond its first school: how to scale the team and technology without building too far ahead of real demand, and what needed to be in place around AI liability, training and governance before broader adoption.
Grand Rounds video session with Alexander Gorrie, Krupa Shankar, CTO Berkan Sesen and curator Jane Vyshnova
Alexander Gorrie Founder Alex came to CTO Grand Rounds with several important technical decisions already being actively worked through. One question from the panel reframed the discussion: “How will you know that the result is actually good?” It sharpened the conversation around how those decisions should be sequenced and prioritised.
Grand Rounds video session with Tomas Jankauskas, CTOs Neil Catton and Thomas Döhler and curator Jane Vyshnova
Tomas Jankauskas Founder of Neural DEEP Tomas came to Grand Rounds with a question he'd been wrestling with while bringing AI-driven innovation into Toyota: which ideas to pursue, and how much to build before anything was approved, in an organisation where every new idea needs to pass through many hands.
  • Products with a purpose

    Technology that delivers a real outcome for people, not technology for its own sake.

  • Energy and enthusiasm

    Founders and teams with the passion and drive to address a problem they have seen for themselves.

  • The story before the numbers

    The first question is what you are trying to do and why: what you saw and why you started.

  • Listening more than talking

    Nobody walks in to say “I know better.” We ask what drives a decision and what has not been considered, then work through the options together.

  • Understanding before fixing

    First the people, the business and the why, and what has and has not worked, so the first problem found does not start constant firefighting.

  • Experience, not just knowledge

    Modern and AI tools assist. Architecture, security, recovery and user experience still need people who have built and run real systems.

About us

Jane Vyshnova

Curator of Grand Rounds

I've spent 12 years building partnerships between founders, technical teams, and the people who fund them. Somewhere along the way I noticed the same pattern over and over: brilliant fractional CTOs with real availability, and founders who had no idea they existed, let alone how to reach them.

Grand Rounds is my answer to that gap. The name comes from medicine, when a case is hard, doctors don't decide alone, they bring senior specialists around the table together. I built the same thing for technology.

"People need people. Nothing else works."

I'm the one who listens to your problem, asks the questions you didn't think to ask yourself, and figures out exactly which 2 or 3 people in my network have actually lived through it before.

Jane has been working across the industry since 2014, connecting startups, retailers, B2B companies, manufacturers, and expert teams around meaningful partnership opportunities.

Her experience includes building bridges between companies and ecosystems, ready-made technology solutions, manufacturing-focused initiatives, and sustainability-driven projects. Over the years, she has helped create practical collaboration models between businesses, technology providers, and industry experts.

For Jane, partnership strategy is not just part of the work - it is the DNA of her professional experience. Her focus is on identifying where teams, platforms, products, and industries can strengthen each other and turning those connections into real opportunities.

What founders say after their Grand Rounds session

It's like a hackathon for your real business problems. You bring your challenges and bright minds work on them - with no obligation, no pressure. I walked away with perspectives on investors, encryption solutions, and a connection that could directly benefit my product. Honestly, why rely on one mind, when you can have many?

Saif Alam
Saif Alam CEO at Keepsta

It was an incredibly welcoming space to connect with senior technical minds I wouldn't normally have access to as a non-technical founder. A fantastic opportunity to get real, honest answers to the challenges I was facing - and to walk away with meaningful connections who continue to support me.

Audrey Lee
Audrey Lee Founder of Lumi

CTO Grand Rounds was the best event by far. This is where the founder world and the tech world actually merge, with real introductions instead of leaving people to stay siloed. I was deep in a conversation about cybersecurity and feedback loops - practical advice I could act on immediately.

Hélène Le Roux
Hélène Le Roux CEO at Trippin'

What I valued most was the mix of CTO styles at the table - some all-in on AI, others more measured. As a founder, you don't want someone else's answer, you want enough perspectives to make your own call. I walked away with two strong contacts - people who hit the mark on build support, strategic fit, and investor credibility. The relaxed format made room for real technical conversation, not just quick decisions. Worth coming back for.
