About SecondBrain
SecondBrain Solutions Pty Ltd is an Australian AI workflow automation company building tools for mortgage brokers — most notably Sharp, an AI bank pricing tool that returns a full lender comparison inside Microsoft Teams in about 4 minutes. We're based in Sydney and we operate onshore.
What we do, in plain English
Australian mortgage brokers spend roughly 60–80 hours per month on the admin between fact-find and lodgement: bank pricing comparisons, aggregator data entry, document compliance, valuation ordering. The work is rule-based, repetitive, and not why anyone became a broker. We automate it — inside the customer's own Microsoft 365 tenant, so client data never leaves the broker's environment.
The flagship product is Sharp: submit one pricing request inside Microsoft Teams, get back a full comparison across every lender on your panel in about 4 minutes. The wider SecondBrain platform extends to aggregator data entry (300+ fields per file), document renaming and compliance logging, and automated valuation ordering.
Why we built it
Most "AI for mortgage brokers" tools in 2026 are general-purpose AI products with a broker-flavoured marketing layer. We took the opposite approach: pick the most painful, most repeatable parts of the AU broker workflow — starting with bank pricing — and build a deterministic, tenant-resident tool that does that one thing very well. Brokers using Sharp aren't trusting a language model to invent pricing; they're getting the live numbers from each lender, retrieved deterministically, delivered into the workspace they're already using.
The result is a product that solves a real time problem (2–3 hours of bank pricing per broker per week, eliminated) without introducing the accountability risk of general-purpose generative AI. The broker remains in charge. The AI handles the admin.

James Larkey, Founder
James is the founder of SecondBrain Solutions Pty Ltd. Based in Sydney, he started the company in 2024 to solve a specific problem he kept seeing across Australian mortgage brokerages: the gap between what brokers were paid to do (advise clients) and what brokers actually spent most of their time on (admin between fact-find and lodgement).
James's view on AI in mortgage broking is consistent and slightly contrarian for an AI founder: the broker is irreplaceable, and AI's job is to do the admin so the broker can do the human work. The Best Interests Duty makes that view a legal reality, not just an opinion. This is why SecondBrain's products are deterministic where deterministic matters (pricing, data extraction) and only generative where the output is clearly a suggestion (insights, follow-up prompts).
James writes occasionally about mortgage broker automation, BID compliance, and tenant-resident SaaS architecture on LinkedIn.
How we think about competing tools
We've written honest comparisons of Sharp against the other commonly-named AI tools for Australian mortgage brokers, including Quickli (serviceability) and Bulma (policy intelligence). The honest framing: they do different jobs to Sharp, and most brokerages benefit from running two or three specialised tools rather than one all-in-one platform. A roundup of the full AU AI broker stack is here.
How we think about accountability and trust
Mortgage broking is regulated under the Best Interests Duty (BID) since 1 January 2021. Brokers are personally accountable for credit advice. That accountability cannot be delegated to an AI tool, an aggregator, or a vendor. Our products are designed around that fact: deterministic retrieval where deterministic matters, citations and audit trails everywhere, generative suggestions clearly labelled as suggestions. We've written a longer essay on AI accountability for mortgage brokers if you want the full reasoning.
