Technical diagnosis
Capture the need on site, pre-size the solution and deliver a credible estimate from the very first visit, without tying up your design office.
Who is it for?
For design offices, integrators and manufacturers whose every project demands a technical study before signature: irrigation, acoustics, heating, air handling, process metrology, hydraulic equipment… Worlds where studies are expensive, sales cycles long, and expertise too centralised to be present on the ground.
The business need
The paradox is a familiar one: design-office time is spent upstream of the sale, sometimes on projects that never close. Sales engineers push information to the back office, wait for an answer, and lose the customer's tempo. Meanwhile, competitors respond fast, sometimes with shallow, standardised pricing.
The goal isn't to replace the detailed engineering study. It's to lock in the sale before triggering it: a reliable pre-sizing and a realistic estimate are enough to validate the customer's budget and engage the design office only on projects that genuinely deserve it.
How DARYL helps
On site, the salesperson describes the need aloud, takes photos, adds a note. DARYL extracts the key parameters as visible, editable Smart Tags, applies your sizing rules encoded in the proprietary Knowledge Graph, and proposes a priced pre-sizing. The sales engineer stays in control at every step, and no decision is opaque.
Multimodal capture
Voice, photo, text, document: DARYL accepts inputs as they arrive in the field, including from a phone.
Pre-sizing
Domain rules (hydraulic, thermal, acoustic…) applied to the extracted parameters, with traceable assumptions.
Editable Smart Tags
Every parameter is visible, editable and explained. The salesperson can correct an assumption in one click.
Budgetary offer
A credible offer, close to a full study, delivered at the first meeting to validate the customer's budget.
Industry examples
Agricultural irrigation
Capture the need in the field, pre-size the hydraulic network (flows, pressures, equipment) and hand over a budgetary offer at the first visit. Proven approach with Delta Sud (Terres du Sud group).
Industrial acoustics
From a photo and on-site measurements, simulate room reverberation, recommend acoustic treatment and price the offer before leaving the site.
HVAC & air handling
Assess a building's heat losses, simulate several technologies (heat pump, gas, biomass) and present the best-performing solution with public grants included.
Metrology & process instrumentation
Qualify the constraints of a controlled environment (ATEX, ISO, calibration), cross-check against the installed base and recommend a compliant solution.
Frequently asked questions
Does DARYL replace the design office?
No. The goal is not to replace the detailed technical study, but to secure the sale before triggering it. DARYL produces the pre-sizing and the budgetary offer during pre-sales, so the design office is only mobilised on projects that genuinely warrant it.
What can we hand the customer at the very first meeting?
A reliable pre-sizing and a realistic budgetary offer, together with the site-visit report. That is enough to validate the customer's budget and move the project forward without waiting for the design office.
How does the salesperson capture the need on site?
Multimodally, from a smartphone: voice note, photo, free text or document. DARYL accepts inputs exactly as they arrive in the field and extracts the key parameters as Smart Tags.
Are the technical assumptions verifiable?
Yes. Every parameter is visible, editable and justified: the sales engineer can correct an assumption in one click. The proprietary knowledge graph guarantees traceable results with no hallucination. No decision is opaque.
Which trades run this kind of pre-sales technical diagnosis?
Design offices, integrators and manufacturers whose every project requires a study before signature: agricultural irrigation, industrial acoustics, HVAC and air handling, heating, metrology and process instrumentation, hydraulic equipment.
Can it be used without a permanent link to the office?
Yes, that is the whole point: expertise travels to the field rather than staying centralised. The salesperson qualifies, sizes and prices from the customer's site, without the back-and-forth with the design office.
