Nautis

Freemium

AI-native startup operating system that unifies planning, fundraising, finance, and execution in one human-in-the-loop workspace.

AI Chief of Staff: A supervised agent with full read access to every module that plans, drafts, and executes chained back-office actions across your stack.
Unified Workspace: Fundraising, CRM, Investor Data Rooms, Finance & Runway, Invoices, Equity Calculator, Sales, GTM, Business Plans, Pitch Decks, DocSign, Meetings, Email, and Task Boards in one place.
Human-in-the-loop Approvals: Every outbound action (email, document share, deal log) waits for an explicit founder tap before it ships.
Deck & Pitch Review: Reads your pitch deck end-to-end and flags exactly what investors will catch — weak traction slide, missing 'why now', unclear ask — with drafted fixes.
Investor Matching: Ranks funds by stage, sector, and check-size fit and drafts personalised warm intros for the highest-probability replies.
Fundraising Data Room: Assembles investor-ready data rooms and shares them under founder approval with credentials-vault access control.
Metered, Logged Actions: Every agent action is metered and logged so founders retain audit trail and cost visibility.

Solo Founder Back Office: A single founder runs planning, CRM, deal logging, and light finance without stitching together five SaaS subscriptions.
Seed Fundraise: Founder analyses the deck, matches funds, drafts warm intros, and closes the round as one supervised conversation.
Agency Client Ops: Agencies run multiple client workspaces where the AI handles recurring back-office chores while consultants keep control.
Small Startup Team GTM: A 5–10 person team plans launches, tracks milestones, and manages a small CRM without a dedicated ops hire.
Investor Data Room Prep: Automatically compiles pitch deck, financial model, and cap-table into a shareable data room with permissioned access.

An AI coding agent for Xcode that writes Swift, runs builds, fixes build errors automatically and shows diffs, while source code stays on your Mac.

Automatic Build Error Repair: Runs the Xcode build, identifies compile errors, applies fixes and re-validates the result through an iterative repair loop until the project compiles.
Side-by-Side Xcode Workflow: Sits next to Xcode with real-time build monitoring, diff review and inline approvals so you never leave the IDE to consult an AI.
Codebase Understanding Before Coding: Reads and understands the project structure before writing anything, so generated Swift fits the existing architecture rather than being pasted in blind.
Diff Review Before Apply: Every proposed change is shown as a reviewable diff that you approve or reject, so the agent never silently rewrites files.
Persistent Project Memory: Retains its understanding of your project across development sessions instead of relearning the codebase every time you start.
Local Source Code Storage: Source code stays on the Mac under a privacy-first architecture, with only inference context sent off-device.
Swift and SwiftUI Native: Built for the Apple ecosystem with deep Swift and SwiftUI understanding and native Xcode workflows rather than generic language support.
Usage-Based Credits: Pay per AI request with exact credit costs shown before and after every task, with no seats or subscription commitment.

Feature Implementation: Describe a new screen or capability in plain English and have the agent write the Swift, build it and hand back a reviewable diff.
Build Failure Triage: Hand a failing Xcode build to the agent and let it iterate through compile errors until the project builds again.
Legacy UIKit Modernization: Refactor older Apple codebases toward SwiftUI and current Swift idioms with the agent validating each step against a real build.
Privacy-Constrained Teams: Adopt an AI coding agent at organizations that cannot upload source to the cloud, since the code stays on the developer's Mac.
Occasional Contract Work: Pay only for the requests you actually make, which suits indie and contract Apple developers who do not want a monthly seat.
Code Change Auditing: Use the mandatory diff review step to keep tight control over exactly how AI modifies an app before release.
