The starting point
ZeClinics was not starting from zero. They had webinars, newsletters, a blog with over 40 URLs, an active LinkedIn company page, and paid ads campaigns. In a market where most potential clients were still figuring out what zebrafish-based drug discovery even was, this was genuinely impressive work. They were not just promoting a service. They were building an entire category from scratch.
But sales were not growing at the desired rate. The team was stretched across too many channels, and none of it was converting as efficiently as it should into a qualified pipeline.
What we did
First, we cut the noise and built a content system around making CEO Simone Calzolari the go-to thought leader in the zebrafish niche. We positioned him as the primary commercial and scientific authority of the company on LinkedIn. Not through company announcements, but real expert-led content that educated the audience and built trust over time.
Beyond that, we developed an SEO-driven blog strategy to grow organic traffic and capture demand at the search level.
Then we activated campaigns: connecting with potential clients, enriching their contact data, monitoring engagement signals to identify interested profiles, and reaching out on LinkedIn and email to generate sales opportunities.

leads
In our first month, one post hit 1M impressions, giving us a list of over 100 ICP-matched contacts with a good excuse to start a conversation.
But the outlier aside, the numbers speak for themselves. Over the following year, monthly impressions grew 618 % (from 8k to 57.5k) and new connections increased by 238 % (from 74 to 250 per month). With zero ad spend.
The rest of the team, co-founders and other members, did not just watch from the sidelines. They actively amplified every piece through shares, reposts, and comments, compounding the reach organically.
You could call some of these vanity metrics. We get it. But the real thing is that we built a zebrafish rockstar, and his content started showing up in sales conversations. Potential clients were referencing his posts before anyone had reached out to them.
The SEO results followed the same trajectory. From January 2025 to April 2026, organic traffic grew 200 % (60k) and users 220 % (42k) compared to the previous period. That is why Google AI and other LLMs are citing them when you ask about zebrafish.
All of this translated into a real pipeline: a 112 % increase in leads compared to the previous period, reaching an average of 9 qualified leads per month.
On campaigns, we achieved a 17 % reply rate and a 1.3 % positive reply rate. The zebrafish era is coming, and ZeClinics is going to own it!
In their own words
Working with zebrafish —a highly innovative but still relatively unknown experimental model— requires a strong effort in education and market evangelization. Our future clients need not only to know who we are, but also to understand the value we bring in streamlining their drug discovery pipelines and ecotoxicology processes.
Simbionte has helped us sharpen our focus on this value proposition and strategically deliver our messages to the right target audiences. And it is working. Since the beginning of our collaboration, we have seen a significant increase in inbound requests and, as a result, an increase in both the number and size of our projects.
This has supported a 50 % increase in revenues in 2025 and what is already shaping up to be a record year in 2026.
