The Solo Founder's AI Stack

Nine tools to run product, code, sales and content without hiring — assembled for the one-person company.

  1. 01CursorCoding & Dev$20/mo“Cursor is the tool most other AI coding assistants are measured against: its predictive Tab autocomplete and codebase-aware agent are genuinely ahead of the pack, and building on a VS Code fork means near-zero switching cost. The catch is the credit-based pricing introduced in mid-2025, which makes heavy agent usage hard to budget.”4.7
  2. 02Bolt.newCoding & Dev$25/mo“Bolt.new is the strongest example of the "prompt-to-app-in-the-browser" category: its WebContainers engine runs a real Node environment client-side, so you get editable code, live preview, and one-click Netlify deploy without touching a terminal. It shines for prototypes and MVPs but leans hard on token-metered billing and loses reliability as projects grow complex.”4.4
  3. 03SkarbeSales$95/mo“Skarbe had a genuinely good idea — an invisible, inbox-native CRM that logged deals and drafted follow-ups so founders never had to touch a pipeline board — but the company wound down all operations in April 2026, so it can no longer be signed up for or used. Worth studying as a reference for the zero-input CRM concept; not a product you can adopt today.”3.5
  4. 04MantleBusiness Ops$100/mo“Mantle is the rare cap table tool that gives early-stage founders unlimited stakeholders for free, then charges a flat annual fee instead of taxing you per head like Carta — and its AI document extraction makes migrating messy equity records genuinely painless. It is younger and less feature-deep than incumbents, but for seed-stage teams the price-to-value math is hard to argue with.”4.3
  5. 05NumeralBusiness Ops$75/mo“Numeral is one of the strongest hands-off sales tax tools for venture-backed ecommerce and SaaS startups: transparent $75-per-filing pricing, genuine automation, and human tax experts who actually field state notices for you. Just watch the math — because it is not SST-certified, per-return fees stack up as your multi-state nexus footprint grows.”4.4
  6. 06ArcadeMarketing$50/mo“Arcade is one of the strongest interactive demo builders on the market, and its AI layer — voiceovers, text-to-video, and on-brand generation — makes spinning up a shareable, trackable demo remarkably fast. Just don't mistake the "content generation" framing for a general content suite; it shines narrowly at product demos and walkthroughs, and costs climb quickly once you add seats.”4.4
  7. 07Wispr FlowProductivity$12/mo“The strongest AI dictation app for cross-app writing on desktop: it drops cleaned-up, auto-formatted text into any text field, strips filler words, and reliably clears 150+ WPM. The catch is that it is cloud-only with no offline mode, and the mobile experience is far weaker than the Mac/Windows apps.”4.4
  8. 08Eraser AICoding & Dev$15/mo“Eraser AI is one of the more thoughtful takes on AI diagramming: because everything is diagram-as-code, the AI output stays editable, diffable and reviewable instead of becoming an opaque canvas. It fits engineering teams that want architecture diagrams and design docs living together, though the headline "auto-updating from your code" promise is more assistive than fully autonomous.”4.2
