A connected stack for
every stage of growth.
We work alongside the tools your company already runs on — cap table management, formation, spend management, and accounting — so your books, your equity, and your spend all tell the same story.
Our partners
Clients who run their business on these platforms get the smoothest experience working with our team — and often unlock partner perks along the way.
Carta helps companies manage their cap table, equity plans, and 409A valuations in one place — critical infrastructure once investors, options, and SAFEs enter the picture.
Clerky handles startup incorporation, equity issuance, and standard legal paperwork — the fast, founder-friendly way to get formation documents right from day one.
Ramp gives finance teams corporate cards, bill pay, and expense management with built-in controls — clean, categorized spend data that flows straight into your books.
QuickBooks Online is the general ledger at the center of most of our engagements — the system our team works inside every day to keep your books accurate and audit-ready.
Gusto runs payroll, benefits, and HR compliance for growing teams — payroll data that reconciles cleanly against your books instead of arriving as a mismatched lump sum.
How partnerships help
Working with clients on these platforms means less setup, fewer reconciliation surprises, and a faster path to clean books.
Faster onboarding
We already know how to connect and read data from these platforms, so getting your books set up takes days, not weeks.
Fewer reconciliation gaps
Cap table events, spend, and formation filings land in the right place the first time — instead of surfacing as surprises at close.
Perks along the way
Many of our partners offer current clients of Simplexity Accounting discounts or credits — ask your contact what's available for your account.
