Why TSA

Most firms report on technology.
We interpret what it means for your capital.

We go beyond checklist audits, uncovering execution risks, scalability constraints, security exposure and technical debt, and quantifying how they affect growth, margins and deal dynamics.

Think of it as insurance. Technology now carries the largest share of enterprise value, the diligence costs a fraction of the cheque that rides on it, and the risks we expose never get the chance to become your losses.

Built for decision-makers

You don't need to be technical to make the right call.

Most of our readers are investors, founders and boards, not engineers. So every finding is written twice: in full technical depth for your experts, and in plain business language for the people making the decision. What it means, what it costs, what to do next.

The same finding, both ways:

Technical: "Stateful component on the critical delivery path runs without horizontal redundancy."

Plain language: "If this one piece fails, customer data is lost with no recovery, and it has no backup. Fixable in about two months; worth resolving before signing."

The investment lens

Risk

What could affect valuation or execution?

Impact

How material is the issue?

Recommendation

What action is required?

Investment Consideration

Should this influence price, structure, or post-deal planning?

Where we stand

Impartial, by design.

Objective and independent.
Built only on the evidence we are given.
It informs your decision. It never makes it.

The TSA Way · Framework 2.0

The Technology Value Gauge (TVG)

Every assessment lands on one picture. The TVG plots Tech Latitude: does it work? (process, people & potential ↔ technology infrastructure) against Product Longitude: is it working? (users & data ↔ product). Higher scores move a company closer to the core, and the 12 Assessment Blocks below are what feed it. Hover across the gauge to see where your business would stand.

THE GAUGE

Where would your business land?

Hover over the zones and axis labels to explore. Each zone tells you what that position means for investment risk, and what an assessment would focus on.

Every TSA engagement scores all four dimensions from the 12 assessment TABs.

The 12 Technology Assessment Blocks

Twelve blocks, each scored on a named spectrum against same-stage peers, and every flag they produce anchored to evidence. Open a block to see the questions we ask and what it helps us evaluate.
