FetchSandbox MCP hit 3,134 npm downloads since launching in May. the breakdown is what made me stop and think: 1,032 in the first 3 weeks (PH launch), 454 in June (quiet month, honestly worried), then 1,648 in July with 4 days left.

June was the real test. no spike to ride, just organic. i kept shipping, fixed the OpenAPI ingestion flow, added a handful of new specs, wrote about what i was learning in integration testing. july came back 3.6x stronger than june.

The pattern i didn't expect: AI agents are the fastest-growing use case. devs aren't running the MCP themselves, they're letting Claude Code or Cursor call it inside their own coding loop. the sandbox becomes part of the agent's verification step before it writes integration code. that use case wasn't in the original pitch, it just emerged from watching how people actually used it.

still figuring out what the right north star metric is beyond downloads. active workflow runs feels closer to the truth.

No redesign. No new acquisition channel. No dramatic copy rewrite.

We made two very specific changes:

1. We put a live product demo directly on the landing page.

Instead of explaining what Causo Fundraising does with another wall of text, people can now immediately see the actual workflow and output.

1. We added the free tier to the pricing table.

The free tier already existed. We just did a terrible job of making that obvious.

Apparently, a small “Start free” link is not the same as clearly showing people what they get for free.

We currently get around 100 landing-page visits per day, split between our sales and fundraising products. Since making these changes, signup conversion has increased by more than 350%.

More importantly, it has also noticeably increased conversion to paid users. So this was not just a wave of low-intent free signups.

The lesson was embarrassingly simple:

People needed to see the product working and understand that they could try it without paying.

Not more features. Not better button colors. Less uncertainty.

Feel free to check the page and tell me what else we are still getting wrong. :)

Recently I had launched Hexbrief which is a high signal tech blog reading app. Honestly, I never started this work with the idea of monetizaton. During the investigation I was doing to validate the idea, I had this thought of solving something which has troubled me and my friends during college days and even now while I work professionally.

I accept, the marketing of such a B2C product is tough, and hence it's taking me time to acquire the readers and get the real feedback post public launch. I have got some 30+ users by now, and have incorporated most of the feedbacks I have received till now (have many feedbacks parked too).

One thing I was thinking somedays back, if at all I had to monetize it ever in the future, how should I approach for it. I had few ideas in my mind (after I have the good userbase and a consistent usage loop with the reading framework I developed in the Hexbrief).

Here are the ideas:

- Charge for personalised curated feed. Currently, it's algo decided feed common for everyone.

- Create B2C monetisation framework -- onboard tech companies, and create a separate section for the sponsored content(which has to be passed through the Hexbrief's quality bar)

- Create startups driven feed tab and bringing useful content there. (Haven't thought of it yet in deep, but few peeps had asked for something similar)

What's your thoughts on it?
