MainClose is the only platform that guides a first-time small business buyer from initial valuation through the first year of ownership — built for the SBA buyer, distributed through brokers.
Tens of thousands of buyers close SBA deals every year using spreadsheets, email threads, and generic tools that were never built for them.
The number of small business transactions grows every year. The tools have not kept up. The white space is enormous.
MainClose is organized around the actual buyer journey. Data flows forward from phase to phase. The buyer never starts over.
The buyer's first home base. Upload financials, run AI-assisted SDE normalization across 25+ add-back categories, model deal structures, and generate a ready-to-send LOI — all in one place. Most first-time buyers overpay because they don't know what to add back. DealDesk fixes that.
A structured, trackable due diligence workspace designed for a solo buyer, not a PE team. Replace the chaotic email-and-Dropbox approach with a purpose-built SMB environment — 80+ item checklists, secure VDR, risk registry, and AI document review in one unified space.
The most underserved phase in any existing tool. CloseKit manages lease transfers, license and permit tracking, APA templates, seller finance agreement builder, SBA closing checklist, and escrow coordination — all in one kanban-style workflow. This is our primary moat.
Day one of ownership is terrifying. TransitionOS manages the first 90 days: seller knowledge transfer, SOP library, staff introductions, key relationship register, and training logs. Nothing like this exists in any tool on the market today. We own this phase entirely.
The long-term retention engine. Once the transition is complete, OwnerDash becomes the buyer's operating dashboard — managing the seller note, tracking KPIs against the original deal model, and monitoring first-year performance. This is where lifetime value is built.
Every competitor stops at due diligence. The 60-day window from LOI to close — lease transfers, licenses, APA coordination — is handled entirely by attorneys charging $400/hr and broker email chains. We own this.
Brokers close 6-12 deals per year and recommend tools to every buyer. By building the broker portal first, we turn the sales channel into the product. We don't acquire buyers — brokers bring them.
Seller finance tracking, KPI dashboards, and transition workflows mean the product stays relevant for 12-36 months after closing. Competitors disappear after close. We become the operating system for the business.
A disciplined phased build that ships value at every step, deepens the moat at each version, and scales to the full platform vision.
MainClose turns business brokers into the most professional advisors in their market. Create client workspaces in 60 seconds, monitor every active deal from one dashboard, and deliver a white-glove buyer experience that closes more deals.
The broker who uses MainClose can credibly tell every seller: "My buyers don't fall out of escrow."
Buyers pay once per deal. Brokers subscribe for recurring access. Everyone wins.
