White space

1  No UK occupier-agent portal with structured lease data

This is the single most immediate white space in the market — and the one Harla's GTM beachhead directly addresses. Occupiers today manage their lease commitments through spreadsheets, PDF filing, and manual tracking. Their agents and advisors work from the same fragmented, unstructured data. There is no UK platform that extracts structured terms from existing leases, organises the associated documentation, and presents it as a shared, live view accessible to both the occupier's team and their agents. This gap is the entry point for Harla: immediate ROI, no behaviour change required from landlords, and a dataset that powers everything that follows.

2  No UK-native occupier platform

The only meaningful occupier-side SaaS platform (Occupier) is US-built, designed around US lease law (GAAP), US lease structures (triple-net, gross leases, percentage rent), and US market conventions. UK commercial leasing operates under different law (Landlord and Tenant Act 1954), different lease structures (FRI leases, turnover rents, rent review mechanisms), different professional frameworks (RICS, SDLT), and different market conventions. No UK-native occupier intelligence and portal platform exists.

3  No multi-party transaction platform

Every existing tool serves one party. Landlord tools serve the landlord. Legal tools serve the solicitor. Occupier tools serve the tenant. No tool sits in the middle and serves the transaction itself — meaning the most critical relationship in a lease deal (the landlord-occupier commercial negotiation) happens entirely outside any structured platform: in emails, phone calls, and Word documents passed back and forth.

4  No full deal arc

Even within a single party's workflow, no tool follows the deal from its beginning (first approach, interest, tour, commercial discussion) through its end (heads of terms, legal instruction, legal completion, handover). At each stage, parties switch systems — from email to spreadsheet to PDF to DocuSign — losing context, creating errors, and consuming time. The deal arc is invisible to any single system.

5  No structured negotiation layer

Heads of terms — the document that captures commercially agreed terms before legal drafting — are produced in Microsoft Word, emailed as attachments, redlined by email, and never structured. There is no platform that captures negotiated positions, tracks changes, presents agreed terms in a clean format, and creates an audit trail of what was agreed and when. This is the most dangerous gap in the leasing process and the clearest Phase 2 opportunity.

6  No cross-professional coordination

A commercial lease involves the landlord, the landlord's agent, the landlord's solicitor, the occupier, the occupier's agent, and the occupier's solicitor — at minimum. Each professional uses a different system. Coordination happens by email and phone. Deadlines are missed because nobody has a shared view of where the deal is. No platform creates a shared workspace for all parties.

7  No live deal intelligence

The information generated inside a live deal — negotiating positions, timeline, clause movement, party behaviour, deal velocity — is almost entirely uncaptured. It exists in email threads and version-controlled Word documents. No platform captures this data structurally, meaning the market learns nothing from individual transactions. Harla's execution layer generates this data as a by-product of managing the deal, creating the compounding Phase 3 intelligence advantage.

Harla's defensibility is structural, not feature-based. The moat deepens with each transaction processed and each party added to the network. The following describes the five layers of competitive advantage that accumulate as Harla scales.

Data accumulation

Every lease transaction managed through Harla generates structured, timestamped data: negotiated terms, deal timeline, clause movement, party behaviour, final agreed positions. This is data that does not exist anywhere else in the market — it is generated by Harla's execution layer as a by-product of running the deal. As transaction volume grows, Harla's dataset becomes the most comprehensive record of how UK CRE lease deals actually happen: what terms are negotiated, how long deals take, which clauses move, which parties delay. This data is extraordinarily valuable for benchmarking, deal intelligence, and ultimately pricing — and it cannot be replicated by a competitor that does not own the execution layer.

Two-sided network effects

Harla operates as a two-sided marketplace: landlords bring occupiers, occupiers bring solicitors, solicitors bring the next landlord. Each successful deal adds another node to the network. As more solicitors use Harla, landlords who want solicitor connectivity are incentivised to use Harla; as more landlords use Harla, occupiers are brought onto the platform for every deal. Unlike a single-sided SaaS product, this network creates a structural lock-in: leaving Harla means leaving the network of counterparties who already know how to transact on it.

Professional trust infrastructure

Leasing involves high-value, legally binding commitments. Once a landlord, solicitor, or occupier has trusted Harla with a live transaction — and experienced that the deal closed correctly, on time, with a complete audit trail — the cost of switching is not just functional but reputational. Harla becomes part of the professional standard of care. This is analogous to the role DocuSign plays in contracts: once it is the standard, deviating from it requires justification.

UK regulatory & market depth

Harla is built from the ground up for UK commercial lease law and market convention: the Landlord and Tenant Act 1954, SDLT, FRI lease structures, RICS standards, UK rent review mechanisms, and UK solicitor professional obligations. Building this correctly requires deep domain expertise that a US-based competitor cannot quickly replicate through a "localisation" project. MRI and Yardi have been in the UK for decades and still primarily sell Americanised products with UK configuration bolted on. Harla's UK-native architecture is a genuine moat against horizontal expansion from US platforms.

Integration depth & workflow embeddedness

As Harla connects to the systems that surround the leasing workflow — property management platforms (Re-Leased, Yardi), legal practice management systems, Companies House, Land Registry, EPC registers, market data feeds (CoStar, EG) — the platform becomes increasingly embedded in professional workflows. Each integration adds switching cost and makes Harla more valuable to both sides of the deal. This creates a "hub" effect: the more systems connect to Harla, the more essential Harla becomes to every transaction that touches those systems.
