Requirements die in Telegram
Specs in chats, decisions in email, versions in Excel. By prototype stage nobody knows what was agreed. One missed requirement = $15–50k rework.
$15,000–$50,000 average rework cost

Most hardware startups fail not because of bad ideas — but because of broken processes
Finance has no idea what engineering decided
P&L in one Excel. BOM in another. Specs in a wiki. When design changes, nobody updates the model. You make million-dollar decisions blind.
3–5 days to compile an investor report by hand
Critical deviations surface too late
No system watches your parameters. A 5% weight deviation compounds into a certification failure. You find out at the physical prototype — when it is expensive.
40% of hardware startups cite process chaos as failure #1
Who it’s for
One product — four ways to read it
Pick your role and see the win in your own language. One system, no jargon.
Make decisions with your eyes open
- Live product economics: change a parameter, instantly see the margin impact
- Know whether the product will survive the market — before the first prototype
- One source of order instead of specs in chat and decisions in email
The method The whole chain — from the voice of the market to the actual bolt
Every layer is linked to the one before it, and every deviation is caught automatically. One workspace — from what the market wants down to the physical part. Engineers know this as end-to-end L1–L7 traceability.
L1
Voice of the customer / market
What the market wants — or the OEM requirement (RFQ). And what competitors offer
Auto market scan, weekly
L2
Product definition
Every parameter with a target and a budget — what the economics allow
L3–L4
How the customer will feel it
Product directions, scored against competitors
Criticality traffic-light (Ki)
L5–L7
Objective data
Measurable parameters: performance, system, materials — target vs actual
Auto-alert on a ≥5% deviation
CERT
Certification — separate
Not a level, a separate layer: traced from the objective data and standards (R79, R152…)
Auto certification tag
One connected flow — from market voice to a shipped product
1
Voice of Customer
Capture real customer needs
2
Finance Model
Economics and allowable investment — right after market, linked to parameters live
3
Product Definition
Every parameter with competitive benchmarks
4
Measurable parameters
Physical parameters + auto deviation alerts ≥5%
5
Validation
Test plan auto-generated from requirements
6
Certification
Regulatory requirements tracked from day 1
Hardware Confidence Engine™ Predict your product’s market success before the first prototype
SpecChain connects objective product parameters to customer perception scores, market-share coefficients and profitability impact. Change a spec → see the market-share impact immediately. The result: a Plan vs Fact report — what happens if you ship today.

Plan vs Fact
Today: 72% of target
Example: robotics
A team spots that sensor weight is 15% over target — 3 months before ordering parts, not on the prototype.
Example: EV components
Pricing at $340/unit looks viable in a spreadsheet. The engine shows willingness-to-pay peaks at $280 — the parts list gets adjusted before tooling.
Who it’s for
One process — any kind of hardware
From a first-prototype startup to a team with a dozen products — the same path from idea to revenue.
🚗
Cars & electric vehicles
Electronics, power, interface — tied to the regulations (R79, R152, R10)
🏥
Medical devices
Step-by-step verification, test plans, traceability all the way to the certificate
🌾
AgTech & industrial
Performance and throughput, yield estimates, validation in the field
✈️
Aviation & robotics
Traceability for aviation standards (DO-178/AS9100), supplier reliability, mean-time-between-failures targets
⚙️
Tier-2/3 suppliers
From the customer RFQ to cost-per-part: NVH, brakes, plastics, castings. Materials, testing, cost, certification (IATF, ECE R90). PPAP/SPC on the roadmap.
🧱
Materials & components
From composition and properties to testing and cost: metals, polymers, composites, coatings. Target and actual on every parameter.
👟
Consumer & wearables
Sneakers, gadgets, appliances — from market need to parameters, price and certification. Competitiveness before the first sample.
🛠️
Machinery & equipment
From spec to assembly: brake discs, drives, tooling. Parameters, reliability, standards, cost — linked in one chain.
Full team. One price. No per-seat surprises.

Questions hardware CTOs actually ask
Task trackers are about tasks. SpecChain is about the product itself: requirements, parameters, validation, certification and the financial model, linked into one chain. When weight goes up 5%, the system sees it and shows the margin impact.
