Incorporation & Startup Stack Stinger

SkillCommerce & finance

Company formation decision toolkit for software startup founders. Covers formation platform selection (Stripe Atlas, Clerky, Doola, Firstbase), entity type advice (Delaware C-Corp vs LLC vs international), EIN workflow, startup banking (Mercury, Brex, Relay), bookkeeping (Pilot, Bench), and the minimum founder-paperwork checklist including the 83(b) election. Activate when the user says "incorporate my startup", "which formation platform should I use", "Stripe Atlas vs Clerky", "set up Mercury or Brex", "EIN for my LLC", "83(b) election deadline", "Delaware C-Corp vs LLC", or asks about the minimum paperwork to form a company. Do NOT activate for ongoing tax compliance, cap-table management (Carta/Pulley), fundraising mechanics (SAFEs, priced rounds), or post-formation state filings — those exceed this stinger's scope.

Decision toolkit for incorporation-startup-stack-worker-bee. It encodes the triage logic, comparison tables, and step-by-step workflows for every phase of company formation and early back-office setup.

Always start with the entity-type decision (Step 1) before touching platform selection. Platform choice is downstream of entity type; reversing the order produces conflicting advice.


Step 1 — Entity type decision

See guides/00-entity-type-decision.md for the full decision tree.

Fast-path rules (2026):

  • VC-funded intent + US founders → Delaware C-Corp. No discussion needed.
  • Bootstrapped, profitable from day one, no outside equity → Wyoming LLC or Delaware LLC.
  • International founders with complex holding needs → consult guides/06-attorney-triggers.md first.

The Delaware franchise tax is $450/year (Assumed Authorized Shares Method). The penalty for choosing wrong is $8K+ in conversion costs. See guides/00-entity-type-decision.md.


Step 2 — Formation platform

See guides/01-formation-platforms.md for the full 2026 comparison table (pricing, processing time, included services, best-for profile).

2026 pricing at a glance:

PlatformOne-timeAnnual (yr 2+)Best for
Stripe Atlas$500$100 (RA)Solo/small SaaS, non-US founder speed
Clerky$425–$799$99/yearYC-track, SAFE activity, complex equity
Doola$297–$597$300–$500International, lowest entry price
Firstbase$399–$599$299/yearNon-US founders, compliance dashboard

Step 3 — EIN acquisition

See guides/02-ein-workflow.md. Online IRS application: ~4 business days. Complete IRS Form SS-4 online at https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online.


Step 4 — Banking

See guides/03-banking.md. 2026 FDIC pass-through update: Mercury = $5M, Brex Vault = $6M, Relay = $0–$30/month. Source: research/external/mercury-vs-brex-banking-2026.md.

WARNING re: Mercury and international founders: Mercury executed mass account closures for sanctioned-country passport holders in August 2024. International founders should consider Relay as primary alternative. See guides/03-banking.md.


Step 5 — Bookkeeping

See guides/04-bookkeeping.md. Upgrade trigger: monthly expenses > $25K–$50K, or preparing for Series A.

WARNING re: Bench: Bench shut down December 27, 2024 and was reacquired. Current operational status must be verified before recommending. See guides/04-bookkeeping.md open question.


Step 6 — Founder paperwork minimum

See guides/05-founder-paperwork.md. Correct order:

Entity formation → Stock purchase + vesting agreements → IP assignment (PIIA/CIIA) → 83(b) election within 30 calendar days → Banking setup → Bookkeeping setup

CRITICAL: The 83(b) election is a 30-day hard deadline. No exceptions. IRS Form 15620 now enables electronic filing (available July 2025). Source: research/external/83b-election-guide-2026.md.


Step 7 — Attorney triggers

See guides/06-attorney-triggers.md. Get a human attorney when: international holding structure, complex IP ownership pre-formation, co-founder equity dispute, SAFE notes at formation, accelerated vesting disputes.

Critical directives

  • Explicitly call out the 83(b) election 30-day deadline in every C-Corp output. See guides/05-founder-paperwork.md and research/external/83b-election-guide-2026.md.
  • Verify Bench operational status before recommending. See guides/04-bookkeeping.md open question.
  • State attorney-required triggers explicitly. See guides/06-attorney-triggers.md.
