What to tell us during betaWhat kind of feedback is most useful right now - smoothness, rough edges, and bugs - and how the in-app reporter gets it to the people writing the code.What we don’t do yetWhat Tenacap deliberately does not do today, what to do instead, and which of them are planned.Tenacap for LLCsWhat changes when your company is an LLC instead of a C-corp: units not shares, no options/409A/83(b)/QSBS, no model of capital accounts or profits interests, the flat $400 Delaware annual tax (from tax year 2026), and what is on the roadmap.
Core workflows
Importing your cap tableBring an existing cap table into Tenacap from Carta, Pulley, Mantle, an OCF bundle, the Tenacap workbook, or a spreadsheet of your own, in the app or through Claude. Every figure is reconciled against the source before anything is committed.Importing stakeholder emailsCap-table exports rarely carry email addresses. Upload a contact sheet, review the name matches Tenacap proposes, and fill in every stakeholder’s email in one pass.Managing your cap tableAdd stakeholders and share classes, issue and transfer shares, and read the fully-diluted ownership view.Share buy-backsRepurchase shares from one or more sellers in a single transaction, preview the cap-table effect, route a board consent and a repurchase agreement per seller for e-signature, and retire the treasury shares by board resolution.
Equity instruments
SAFEs & convertiblesRecord SAFEs and convertible notes with a cap, a discount or both, generate a YC post-money SAFE agreement, send it for signature, and see how each converts in a priced round.Options, grants & vestingCreate an option plan, issue ISO or NSO grants, attach standard or custom vesting, and record exercises - with grant notices ready to sign.Vesting calendarA company-wide, time-ordered view of who vests next - every active option, RSU, and RSA grant in a 30-, 90-, or 365-day window, with cliffs marked. Also where you add vesting to founder shares that were already issued.Restricted stock & 83(b)Issue restricted stock with or without vesting, from your equity plan or outside it, generate the purchase agreement (RSPA) or attach one already signed, prepare the 83(b) election, and track the 30-day filing deadline.Phantom equity & SARsRecord phantom stock and stock appreciation rights: promises to pay cash tied to the value of your shares. Create a plan, grant awards, record payouts, and choose whether they count in fully diluted.
Documents
Compliance & tax
Compliance & taxRecord 409A valuations - or the board FMV determination you have instead - prepare and track 83(b) elections, watch Rule 701 limits, export Form 3921, and follow each holding’s QSBS clock.Option HoldingsA per-grant compliance roll-up for stock options - Rule 701, 83(b), Form 3921, the ISO $100k limit, the AMT-ISO preference, and dispositions - so you can see what each grant might trigger at a glance.QSBS (§1202)A per-holding view of the Qualified Small Business Stock clock and tests - the holding period (more than five years, or the 3/4/5-year tiers for stock acquired after July 4, 2025), the $50M or $75M gross-assets test, and the active-business attestation - with a conservative estimate and a plain not-tax-advice disclaimer.ASC 718 stock-comp reportMeasure grant-date fair value for every option grant with Black-Scholes, recognize the cost straight-line, and produce an auditor-ready expense schedule from persisted assumptions - reproducible years later.Delaware franchise taxPrepare a Delaware Annual Franchise Tax Report from your cap table (C-corps) - computed both ways with the far-cheaper Assumed Par Value method recommended - or see the flat June-1 annual tax for LLCs ($400 from tax year 2026), with a filing link and an optional reminder before the deadline.BVI companiesA British Virgin Islands business company gets BVI resolution wording, a reminder to file its register of members within 30 days of a change, its annual government fee date, and share classes authorized without limit.
Sharing & modeling
Stakeholder portalInvite founders, employees, and investors to a read-only view of their own holdings, vesting, options, and estimated value.Scenario modelingModel a priced round, watch outstanding SAFEs convert line by line, and see the resulting fully-diluted ownership before you commit.Recording a priced roundTurn a modeled Series A into real records: issue a new preferred class, take in the new money, and convert your outstanding SAFEs and notes - all as one atomic, tamper-evident ledger entry.Export & open schemaExport your cap table to CSV or open-schema JSON, or build one complete archive of every record and document with a manifest you can verify - your data leaves whenever you want it to.Exit waterfallEnter an acquisition or liquidation value and see who gets what - stacked liquidation preferences, the convert-or-take decision, participation caps, accrued dividends, and option net exercise, all as a private projection.Founder calculatorsQuick answers off your live cap table - how many shares to grant for a target %, and how much option pool you need - using the same math as the scenario engine.Connect your AI assistantAdd Tenacap to Claude Desktop in four steps and talk to your cap table: who owns what, what a round does, add a hire, or set up a new company with or without an export. Claude reads and does the math; you approve every change. Claude Code, tokens and other MCP clients are covered for the technical reader.Confirming what an assistant proposesWhen an AI assistant proposes a change, Tenacap records a proposal instead of making it. What the proposal shows, who may confirm or decline it, what a reason is for, and what happens when the cap table moves first.API referenceEvery capability an assistant can call, as a REST operation: POST /api/v1/{name} with a bearer token, the envelope every answer comes in, the error shape, and the OpenAPI document that describes it all.
Governance & trust
Board approvalsRecord what the board authorized - grants, financings, 409As, pool increases - generate a consent document, link it to the records it covers, and keep an append-only, tamper-evident trail.Cap-table health signalsThe signals that flag what needs attention before your next round - a stale 409A, grants priced without one, overdue 83(b) elections, unsigned or un-approved grants - and where each one now lives across the app.VotingSee voting power by holder and by share class, filter to one or more classes, run a majority calculator against the statutory and charter-defined thresholds that govern a stockholder consent, and send a consent to that filtered set with live tracking against the threshold.Change log & audit trailSee who changed what, when, and why. Every change to your company is recorded as a hash-chained, tamper-evident entry you can filter and export.Email notificationsEmails for time-sensitive things - a 409A about to expire, an 83(b) deadline approaching - before they become a problem. Choose what you receive per event.Roles & permissionsWho can see and do what. Workspace roles (Admin, Editor, Counsel, Viewer) control your team and your outside advisors; the stakeholder portal gives shareholders read-only access to just their own holdings.Diligence packHand an investor, lawyer, or auditor a single zip with your cap table, compliance reports, and audit trail, with a manifest listing a SHA-256 fingerprint for every file.Trust & securityWhat Tenacap is built on, how your data is protected, and who can reach it: encryption, access control, what our operators and a connected assistant can and cannot do, a tamper-evident audit trail, and where your data lives.Closing your account & deleting your dataClosing is a handoff: download the complete archive, affirm you hold it, choose whether we delete our copy now or hold it seven years, then close. What gets erased, what survives, and legal holds.
