At a glance: Best by use case (Delaware C-Corp)
Delaware-specific decision criteria
DGCL alignment
Delaware C-Corp stock issuances run under DGCL § 152 (consideration); the stock ledger is required under § 219 (and is the controlling record of stockholders); certificate of incorporation amendments under § 242 (majority of outstanding shares); written consents of stockholders under § 228; appraisal rights under § 262; ratification of defective corporate acts under §§ 204 and 205. Tools that treat Delaware as a generic US state miss these specifics. Tools that bake DGCL into the workflow surface the right resolution forms, threshold language, and statutory ratification procedures.
409A bundling versus appraiser independence
Carta, Pulley, Mantle, and Eqvista bundle 409A valuations into their paid plans, typically through a sister or affiliated appraiser. The bundled approach is convenient and cheaper at the small-corporation end. Octelligence integrates with external 409A providers rather than bundling. The external approach is more defensible in an IRS examination because the appraiser's independence is unambiguous. Both approaches comply with Internal Revenue Code section 409A; the choice is about defensibility versus convenience.
ISO/NSO designation discipline
US options must be designated ISO or NSO at grant under IRC §§ 422 and 83. ISO designation requires the grantee to be an employee, the strike to equal at least the 409A fair market value, the plan to be shareholder-approved, the term to be ten years or less, and the annual vesting value (at grant-date fair market value) per grantee to be capped at $100,000. Strong cap-table tools enforce these conditions at grant time; weak tools accept any designation and surface the error at year-end tax reporting.
US securities-law exemption tracking
Every share or option issuance must qualify for a Securities Act exemption (Rule 506(b), 506(c), Section 4(a)(2), Regulation A). Strong tools track the exemption per issuance, the investor's accredited status, the Form D filing date, and the state blue-sky filings. Weak tools treat issuances as undifferentiated. The audit trail matters at the next financing's diligence.
Venture-investor adoption
Most US VCs accept any cap-table tool but have preferences. Carta is the most common default among institutional VCs. Pulley is common at very early stages. Mantle is growing. Smaller seed funds, angel investors, and family offices are tool-agnostic. If a lead investor strongly prefers a specific tool, that preference is usually worth honouring.

Frequently asked questions
Why does the DGCL matter when picking cap table software?
Delaware C-Corp specifics: stock issued under DGCL § 152 with board-determined consideration; certificate of incorporation amendments under § 242; stock ledger required under § 219; written consent of stockholders under § 228; appraisal rights under § 262; ratification of defective acts under §§ 204 and 205. A cap-table tool that treats Delaware as a generic US state will miss these. Tools that bake in DGCL specifics surface the right resolution forms, the right consent thresholds, and the right ratification procedures.
Do I need 409A bundled into my cap table tool?
Not necessarily. A 409A valuation must be prepared by a qualified independent appraiser; the appraiser's independence is a feature, not a bug. Tools that bundle 409A (Carta, Pulley, Mantle, Eqvista) typically use a sister or affiliated appraiser. Tools that integrate with external 409A providers (Octelligence) leave the appraiser fully independent. Both approaches are defensible; the bundled approach is more convenient, the external approach is more defensible in an IRS or SEC examination.
What about Carta's reputation issues?
Carta has had publicized issues around investor-side data handling and the boundary between its fund-side and corporation-side workflows. These have been addressed publicly but the reputation has not fully recovered. For a Delaware C-Corp deciding between Carta and alternatives, the question is whether your investors care; many do not, some do strongly. Ask your lead investor's preference before signing a multi-year Carta contract.
What's the most common Delaware C-Corp cap table mistake?
Treating the cap table as the source of truth and not maintaining the underlying share register. Under DGCL § 219, every Delaware corporation must keep a stock ledger as the official record of stockholders. When the cap table and stock ledger drift apart, the stock ledger controls; reconstructing it from the cap table is a documented diligence failure. The second most common mistake is granting options below the 409A fair market value, which triggers IRC § 409A penalties.
How do US securities-law exemptions matter for the cap table?
Every share issuance must qualify for a Securities Act exemption (Rule 506(b), 506(c), Section 4(a)(2), Section 3(a)(11), Regulation A). Strong cap-table tools track the exemption claimed per issuance, the investor's accredited-investor status, the Form D filing date, and the relevant blue-sky state-securities filings. Weak tools treat all issuances as undifferentiated. The audit trail matters at the next financing's diligence.
Octelligence keeps the DGCL § 219 stock ledger as the source of truth, generates the cap table from it, and integrates ISO/NSO designation, 409A linkage, and DGCL-aware resolution templates.
