CTO.new
CTO.new is a free, ad-supported AI workspace for founders: describe what you want to build or grow by chatting, and multi-agent teams handle research, code, marketing and admin with web browsing, email and scheduling built in. Hire ready-made AI teams from the marketplace, connect Linear, Notion, Vercel, Sentry or any MCP server, and upgrade to Premium from $20 for at least five times the usage.
What is CTO.new?
CTO.new is a browser-based AI platform from Engine Labs that frames itself as the technical co-founder you never had: instead of learning a dozen separate AI tools, you chat with an assistant that plans the work, spins up specialist agents and executes it. The homepage promise is blunt - build your business with AI, free forever - and the product targets people who want to start or grow a company without hiring a full team first.
At the centre is a chat interface with model choice. An Auto mode picks among frontier models from Anthropic, OpenAI, Google Gemini, Mistral, xAI Grok and DeepSeek, and a Surprise me button generates a starting prompt if you do not know where to begin. Requests run in fast, secure cloud sandboxes, so agents can write and execute code without touching your own machine.
The second half of the product is the marketplace. You can hire a ready-made AI team - the Engineering Team ships with a technical lead, backend engineer, frontend engineer and QA engineer - or a Marketing Agency with a strategist, content writer and data analyst. Every listing has its own lead and member roles, and independent sellers can list their own team for sale alongside the platform presets.
Agents are not chat-only. They browse the web, send email, manage calendars and run scheduled tasks, and CTO.new ships integrations for Linear, Sentry, Vercel and Notion. Any MCP server can be plugged in, and the platform will recommend relevant integrations for whatever you are building.
Pricing follows an ad-supported free tier. The free plan includes frontier models, unlimited AI businesses and agent chats, and API and MCP integrations, with limits that reset daily and no credit card or API key required. Premium starts at $20 a month and multiplies usage at least fivefold while unlocking pro agent features and premium-only models.
Because everything runs in the cloud and the output belongs to you, CTO.new sits somewhere between a no-code app builder, an AI coding assistant and a virtual staffing agency. It is a young product from the team behind Engine Labs, and the free tier is designed to work as the trial.

Who is CTO.new for?
CTO.new is aimed first at founders and solo operators who need to get a company off the ground without hiring. If you have an idea, a landing page to ship or a first paying customer to find, the free tier lets you run the research, the build and the marketing chat by chat, and the marketplace lets you add a whole team of agents in one click. Small businesses and local service providers are a natural fit as well: the marketplace already lists ready-made teams for website creation aimed at local businesses, alongside marketing agencies that plan campaigns, write copy and report on performance. Indie hackers, makers and side-project builders use it for the same reason they used to chain five subscriptions together - one chat window handles the code, the copy and the competitive research, and the engineering preset covers architecture, backend, frontend and QA without hiring anyone. Early-stage startups without a technical co-founder are a core segment. The Engineering Team listing is explicitly a full-stack squad that builds, tests and ships SaaS products, with a technical lead who plans architecture and delegates work. Marketers, content teams and agencies get a specialist crew rather than a single generalist model. The Marketing Agency preset bundles a strategist, a content writer and a data analyst, so campaign planning, blog posts, social copy and reporting all happen against the same shared context. Developers and technical teams use CTO.new as an agentic workspace that reaches outside the editor: browsing, email, scheduling and MCP connections to Linear, Sentry, Vercel and Notion mean it can touch the tools a real engineering team already runs on. Finally, anyone learning in public - students, career switchers, first-time founders - can explore the tool free forever, with daily limits that reset and no card required, which lowers the cost of experimenting to zero.
CTO.new Use Cases
Launch a SaaS product from an idea by hiring the Engineering Team preset and letting its lead plan architecture, backend, frontend and QA work.
Plan and run a marketing campaign end to end with the Marketing Agency team, from strategy and blog copy through to performance reporting.

Validate a business idea by asking agents to research competitors, size the market and summarise the findings in one chat.
Automate back-office busywork such as email follow-ups, calendar scheduling and recurring reports with the built-in agent actions.
Prototype an internal tool quickly in a cloud sandbox, then connect Linear, Sentry, Vercel or Notion so it fits your existing stack.
Write and schedule social content, blog posts and newsletters using a content-writing agent that shares context with your strategist.
Sell your own AI team on the marketplace once you have assembled and refined a prompt workflow that reliably works.
CTO.new Pros and Cons
Pros
- The free tier is genuinely free forever and ad-supported: frontier models, unlimited agent chats and AI businesses, no credit card and no API keys, with limits that simply reset daily.
- The marketplace is an unusual advantage - ready-made, pre-tuned teams you hire in one click instead of prompting a single assistant from scratch every time.
- Model choice is broad and automatic by default, covering Anthropic, OpenAI, Google Gemini, Mistral, xAI Grok and DeepSeek, with an Auto mode that routes each request sensibly.
- Agents do more than chat: browsing, email, scheduling and MCP connections to tools such as Linear, Sentry, Vercel and Notion are built in, and everything runs in secure cloud sandboxes.
Cons
- The free plan is ad-supported and rate-limited to daily quotas, so heavy or deadline-driven work will push you toward the $20 Premium tier fairly quickly.
- The marketplace is young and uneven: outside the platform's own engineering, marketing and website presets, third-party listings vary in quality and popularity.
- There is little published detail on data handling, per-model limits inside Premium and enterprise controls, and the product is still early, so regulated or security-sensitive buyers should validate before committing.
