Unstructured paperwork
Invoices, receipts and statements arrive as PDFs, photos and email bodies — each in a different format, each needing manual entry.

01
Our mission
Small teams deserve the operational leverage of large ones.
An independent online retailer handles the same paperwork as a large one: supplier invoices, VAT records, refunds, stock discrepancies and an inbox that never empties. Large companies hire departments for this. Small ones absorb it.
LarkSharp exists to close that gap. We design focused software where a large language model does the reading, sorting and drafting — and a person remains accountable for every decision that matters.
02
The challenge
Operational work scales with revenue. Headcount often cannot.
Disconnected systems
Storefront, payments provider, marketplace and accounting software each hold part of the truth. Reconciling them is slow and error-prone.
Repetitive support
Most customer messages ask the same few questions, yet each requires an accurate, well-informed reply.
03
Products
Three focused products. One intelligence platform.
Each product solves one operational job end to end, sharing a common platform for document understanding, retrieval and auditable actions.

Principles
How we build responsible automation.
- 4.1
Human in the loop
Any action that moves money, changes records or speaks for a business is proposed first and confirmed by a person. Autonomy is earned per task, never assumed.
- 4.2
Grounded, never guessed
Every output is traceable to the document or record it came from. If the data is not there, the system says so rather than inventing an answer.
- 4.3
Private by default
Customer data is processed only to deliver the service, minimised where possible and handled in line with UK GDPR. Customer data is not used to train models.
- 4.4
Measured by outcomes
Every feature is evaluated against real workflows. We ship only what demonstrably reduces manual work without reducing accuracy.
05
Technology
Built on Claude by Anthropic.
Claude is the reasoning core of our platform. The work we automate demands careful reading, faithful extraction and honest uncertainty — the qualities we value most in a model.
