Technology Assessment & Architecture Review

A bounded review of architecture, delivery records and dependencies against a business decision. For a separately agreed assessment, a proposed output is a decision memo separating inspected evidence, assertions and unknowns.

  • One business decision, one bounded review
  • Inspected, asserted and unknown kept apart
  • Advice, separate from authority to implement

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 a technology assessment adds value

It fits an existing technology product with an engineering team or vendor, a sponsor, authorized access and budget for a real next step.

  • A release slips

    A release has stalled, and the next bounded commitment or investigation is not yet clear.

  • Explanations conflict

    Competing architecture explanations need separating into symptoms, supported explanations and hypotheses.

  • A buyer requirement

    The consequences of a buyer requirement for your product are not yet understood.

  • Options were never compared

    Repair, refactor or replacement options have not been compared against the same outcome.

What a technology assessment can examine

Agree what the assessment must help the business decide and which evidence is available; reuse existing records where they answer the question.

  1. Inputs and boundary

    Milestone, roadmap and backlog, architecture, code and build records, failure examples, vendor dependencies and team accounts.

  2. An evidence review

    The critical flow followed, with what was inspected, in which environment and version, and what remains asserted or unknown.

  3. Evidence-linked findings

    Symptoms, supported explanations and competing hypotheses kept apart, with their consequences and limits.

  4. Options against one outcome

    Retain, repair, refactor, replace, narrow scope or change ownership, with transition and operating dependencies.

  5. A decision memo

    The next bounded commitment or investigation, with rationale, alternatives, uncertainty, owners and a reconsideration trigger.

  6. Visible evidence labels

    An annotated memo marks each entry as inspected or observed, asserted or a hypothesis, or unknown.

The assessor advises in writing; your team decides

The decision memo is advice, separate from authority to implement; your sponsor and responsible owners make and accept the decisions.

  1. The assessor

    Reviews the authorized evidence against the agreed question and recommends the next bounded commitment or investigation.

  2. Your sponsor

    The CEO or COO sponsors the recovery decision; finance or the board evaluates material commitments.

  3. Product and engineering

    Product defines a useful milestone; the engineering lead or current vendor supplies technical context.

  4. Acceptance owners

    For enterprise readiness, the buyer's reviewers and your relevant security and data owners retain their own acceptance decisions.

From one business decision to a written recommendation

  1. Write a bounded request

    The decision required, product and milestone, existing evidence, competing explanations, authorized access and the receiving owner.

  2. Take the direct route if you can

    If that record reveals only a known fix, scope that fix directly rather than buying another general review.

  3. Talk with the curator

    Otherwise, discuss relevant assessment experience with the Grand Rounds curator.

  4. Agree question and reviewers

    Before starting, the sponsor and technical counterpart agree the review question, output reviewers and authorized access.

  5. Decide, then implement

    The memo is advice. Leading or implementing the fix needs its own scope, such as a separate fractional or interim mandate.

Illustrative example · a fictional subscription product

Example: a product misses its usage-export milestone

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

The situation

A fictional subscription product misses a usage-export milestone. A staging export exists, but field meanings and production acceptance are unresolved.

What the written recommendation should distinguish

  • Is this an acceptance gap, or does the platform need replacement?
  • Could a bounded mapping repair deliver the same useful export?
  • How do a detachable reporting replacement and a clarified smaller commitment compare?

What to take from it

If an authorized investigation already reproduces an isolated mapping defect and identifies a supported fix, commission that fix with its own acceptance evidence.

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.
