Ohmwise B.V.
01 · The problem
An electric van's pack is 35% of what the vehicle cost and it is the one component nobody measures. Charging habits that look free — a fast top-up at 90% state of charge, a week parked full in July — take 11% of usable pack life in the first four years. On 500 vans at € 22.000 a pack that is € 1,2 million of asset value, gone silently.
Depot managers get kWh delivered and a state-of-charge number. Nothing tells them that one 20-minute DC session at 90% costs more pack life than a week of depot charging.
Lessors discount every returned electric van by a flat 12%, because nobody can prove which packs were treated well and which were abused.
Manufacturers reject roughly four in ten pack claims for want of usage history the fleet was never asked to collect. (22 depot interviews, spring 2026.)
A CAN-bus logger is € 380 per vehicle plus a workshop visit. No operator fits 500 of them to answer a question they only ask at resale.
02 · The solution
Ohmwise reads the standard telematics stream every fleet already pays for — voltage, current, temperature and state of charge at one-minute resolution — and returns a daily state-of-health figure per vehicle, together with the charging behaviour that explains it. No hardware, no workshop visit, first score in nine days.
One API key from the fleet's existing telematics provider. Seven providers supported today, and not a single vehicle is touched.
Our degradation model turns the fleet's own charge history into a state-of-health figure per vehicle, refreshed every night.
The depot gets a ranked list of the habits costing the most life. The lessor gets a signed certificate when the vehicle comes back.
03 · Market
We do not need the whole park. One per cent of it at list price is € 1,6 m of recurring revenue, and we are at € 0,7 m today.
04 · Product
Three surfaces, one model. A depot dashboard ranks vehicles by avoidable loss and names the habit behind it. An API pushes the nightly state-of-health figure into the fleet's own system. And a signed residual-value certificate travels with the vehicle at lease return or resale.
Two leasing companies now accept that certificate in place of their flat 12% deduction.
Illustrative: raw pack telemetry (grey) against the modelled state-of-health curve, crossing the 80% warranty threshold. Not customer data.
05 · Traction
ARR in € thousand at quarter end. Bars are linear from zero and the tallest is € 720k; pilots are not counted.
06 · Business model
One price, per monitored vehicle, per month, billed twelve months in advance with a hundred-vehicle floor. Data and compute cost € 0,55 per vehicle per month, so gross margin is 84%. The average contract is € 21k a year against a blended € 6.400 to win it, which gross profit repays in 4,4 months. The two recurring lines below add to the € 720k of ARR on the previous slide.
Fleet subscription
€ 3,50 per monitored vehicle per month, twelve months up front, hundred-vehicle minimum. 15.600 vehicles today.
Residual-value certificate
€ 50 per pack report at lease return or resale. 1.300 issued in the last twelve months.
Paid pilot
€ 2.500 for ninety days, credited in full against year one. Eleven of the last fourteen pilots converted.
07 · Competition
We are the independent layer between the telematics feed and residual value: brand-agnostic, hardware-free, and auditable. That is precisely the part neither the platforms nor the manufacturers want to own.
| Today's alternative | What they get | What Ohmwise adds |
|---|---|---|
| Fleet telematics suites | Deliver kWh, state of charge and driver scores. No degradation model and no residual-value output. | We read the same feed and hand back pack health — usually as an add-on the platform resells. |
| Manufacturer battery portals | Accurate, but one brand only, and limited to vehicles bought new from that manufacturer. | One comparable score across seven brands in a mixed fleet, used and leased vehicles included. |
| Workshop diagnostic hardware | € 380 per vehicle plus a workshop visit, and it is a snapshot rather than a trend. | No hardware, no downtime, a fresh figure every night: € 42 a year against € 380 once. |
| An in-house data team | Two of our 34 customers tried. Both stopped inside a year: the model needs cross-fleet data. | A method audited annually, at under a fifth of the cost of one analyst. |

What it has to prove
Twenty-four months of runway to € 4,0 m of ARR across 120 fleets, with the method certified. That is 2,4x growth a year — half the 4,9x we just delivered — and it is the evidence a Series A prices.Thank you
Every electric van in Europe will need a battery record. We intend to be the one buyers trust.
