Keeyns

Keeyns is a tax management platform that runs, records and evidences every tax process across your entities, as the work happens, so you can prove exactly what was done, whenever you're asked. It's built for tax leaders at multi-entity companies whose filing obligations have outgrown their team. See it: Keeyns builds your compliance picture from the filing calendar for every jurisdiction you operate in, so your view of what's due doesn't depend on what someone remembered to add to a spreadsheet. Run it: tax, finance and external advisors work in shared workspaces with live Microsoft editing, and every workflow has owners and deadlines per step. Less email spaghetti, less chasing. Prove it: completed workflows lock and every action carries a full audit trail, so when the auditor, the board or due diligence asks, you show who did what, and when.

Lumanu

Lumanu is a B2B payments solution enabling companies to pay anyone, anywhere, with zero vendor setups and managed compliance and tax. Designed specifically for the marketing and advertising vendor ecosystem, Lumanu is your Payments Master Vendor that works within your ERP/AP system. Pay your marketing and creative service vendors globally without the burden of traditional vendor setup and tax compliance. Lumanu streamlines payments, ensures tax compliance, maximizes financial controls, and manages vendor onboarding for businesses engaging with external partners (influencers, creators, affiliates, agencies, freelancers, production vendors, etc.). Positioned within the B2B payments software category, Lumanu is purpose-built for finance, procurement, and operations teams at enterprises, agencies, and platforms who manage payments to a large number of external partners. Lumanu consolidates fragmented payment, compliance, and onboarding workflows into a single vendor relationship within a client’s AP or ERP system. Clients fund Lumanu once, and Lumanu acts as the vendor of record, handling all downstream tasks, including identity verification, vendor onboarding, global disbursements, and tax documentation across 200+ countries.

It replaces the need for clients to individually manage thousands of one-time or short-term marketing vendors with a scalable, compliant infrastructure purpose-built for distributed vendor ecosystems. Key features include: • Vendor Onboarding & Compliance • KYC/KYB, W8/W9 tax form collection, AML/OFAC/PEP screening • Business and bank account verification • Global Payments • Local payment rails (ACH, SEPA, Visa Direct), Swift, and card payments • Local currency disbursement in over 200 countries • Tax Compliance • IRS 1099 reporting, VAT/GST calculations, e-invoicing • Auto tax withholding and invoice generation • Financial Controls • Segregated Workspaces and Wallets • Approval workflows, custom roles, audit logs • Vendor Experience • Self-serve portal, real-time payment tracking, Instant Pay • Dedicated support for vendors worldwide Lumanu is designed to serve the needs of global brands, agencies, and platforms that require robust control, scale, and compliance in marketing-related payments.

Merze

Merze (www.merze.ai) offers cross-border US tax intelligence for global founders. We unify GAAP bookkeeping, corporate tax filing, sales tax nexus monitoring, and entity compliance into one secure platform for high-growth startups. Merze eliminates these risks by unifying all six layers of compliance into one dashboard. The Solution: Six Unified Services Merze provides complete coverage through six integrated pillars. 1. US Business Incorporation Merze handles the structural foundation of your company. Whether you are forming a Delaware C-Corp for venture capital or an LLC for pass-through taxation, we manage the filing, EIN acquisition, and post-incorporation documents. We ensure your entity structure aligns with your fundraising goals from day one. 2. GAAP Bookkeeping & Financial Reporting Investors do not accept cash-basis spreadsheets; they demand GAAP (Generally Accepted Accounting Principles) financials. Merze maintains your books on an accrual basis every month. Our HITL CPAs reconcile your bank feeds, categorize expenses, and generate investor-ready P&L, Balance Sheet, and Cash Flow statements. This ensures you are always ready for a board meeting or Series A due diligence. 3. Corporate & Personal Income Tax Filing We handle the complete lifecycle of income tax compliance. This includes: - Federal Form 1120: Annual corporate income tax return. - State Income Tax: Filings for every state where you have physical or economic presence. - Founder Compliance: Personal tax filings for founders to ensure alignment between personal and business assets. 4. Sales Tax Nexus Monitoring State-level tracking is no longer enough. Following the Wayfair ruling, startups can trigger "Economic Nexus" merely by selling software or goods into a jurisdiction. Merze tracks your liability across 50 states and 11,000+ local tax jurisdictions (cities and counties). We calculate the exact tax owed and file the returns automatically. 5. Registered Agent Services Every US entity is legally required to have a Registered Agent to receive government notices. Merze acts as your official presence in every state where you operate. We receive, digitize, and alert you to legal notices in real-time, ensuring your corporate veil remains intact and your entity stays in good standing. 6. 1099 Vendor Management End-to-end automation for vendor qualification and 1099-NEC filing, including free CPA verification to ensure you pay only for eligible vendors, not blind bulk uploads.

Mosey

Stay compliant with employment and tax requirements in all 50 states, without the expensive legal and accounting fees.Mosey makes employment compliance a breeze so fast-growing companies can hire and operate anywhere—without the administrative burden. What's so hard about hiring people in multiple locations anyway? Each country, state, and municipality has its own employment requirements that need to be maintained on an ongoing basis. Those requirements span HR, tax, accounting, and legal which is complicated and requires deep expertise. As a result, keeping up with the differences and the sheer volume of obligations makes hiring people in many locations expensive and painful. Book a demo for a personal guide to Mosey's platform and alleviate the burden of multi-state hiring.
