My first product

From a caption generator to an acquisition

Try the flow, then run out of free credits the way a new user would. The captions here are samples written for this demo.

The story

  1. Dec 2023

    Co-founded WriteCap and built the MVP

    An AI caption generator for social posts. I worked on product design and the frontend with the team, in React, Next.js and Tailwind CSS.

  2. Launch

    A free trial that sells the plan

    New accounts get 10 credits, enough for two captions. After that, Basic is $11 a month, with a Pro tier planned.

  3. Growth

    Free tools that bring in founders

    I built PriceCal, a pricing calculator for startups on writecap.co/tools. Founders using the free tool were invited to try WriteCap for their launch posts.

  4. Mar 2024

    Acquired

    WriteCap was acquired, including PriceCal. It was my first product, and my first exit.

Write-up

WriteCap

Say no more. Tell it who the post is for and how it should feel, and get a caption.

The problem

Small businesses and creators post every day, and writing a caption that sounds right for a property listing, a new product or an event takes longer than taking the photo.

What we built

  • A caption generator shaped around real uses: personal posts, real estate, fashion and beauty, and events.
  • You describe the audience and the emotion you want, and it returns a caption tailored to the post.
  • Credit-based pricing, so the free trial shows the value before asking for a card.

What I learned

  • Free tools are distribution. PriceCal answered a question founders were already searching for, and was built to put WriteCap in front of the people launching products.
  • Pricing is product. A small, clear free allowance made the upgrade moment obvious.
  • Shipping beats polishing. The MVP went from idea to acquisition in about four months.
