Founder Lessons from Invirsa’s Journey: Pivoting with Discipline
Every founder’s story includes moments of momentum. The more useful stories also include the moments when the original plan stops working.
In a recent Rev1 Founders’ Story conversation, Isaiah Shalwitz, co-founder and senior vice president of operations at Invirsa, shared a candid look at what it takes to keep building when the path changes.
Invirsa’s work is rooted in life sciences, but the lessons from its journey apply broadly to entrepreneurs building companies in SaaS, AI and other advanced technology markets.
Invirsa’s relationship with Rev1 has been part of that journey from its earliest years.
Founded in 2014, the company has been headquartered at Rev1 Labs since shortly after its launch and participated in one of Rev1’s first Customer Learning Lab cohorts in 2015. As Invirsa’s needs and opportunities evolved, the company continued to draw on Rev1’s advisory resources, connections, capital, talent network and space. That ongoing relationship has provided another source of support as the team navigated a complex and changing development path.
Keep Learning as the Market Changes
One of the clearest lessons is the importance of staying close to the market, even after early validation. Invirsa began with a promising opportunity in viral pink eye, supported by data, intellectual property and a credible business case. But markets shift. Competitors fail. Regulatory expectations evolve. Investor interest can change quickly.
As Invirsa’s science continued to show promise, the original opportunity became more difficult to advance. Rather than force the company into a shrinking lane, the team kept looking at the data. That discipline helped reveal a new potential indication connected to diabetic eye disease and blurred vision.
The pivot was not obvious. In fact, a critical aspect of the opportunity was that the condition had largely been overlooked. As the Invirsa team connected the clinical data, patient need and commercial potential, the company found a clearer and more compelling path forward.
Rigor Is a Survival Skill
Isaiah spoke about rigor as a survival skill. Invirsa made hard decisions about funding, vendors, clinical development, regulatory strategy and team building. Some decisions worked. Others created unexpected challenges. But the company’s ability to stay capital efficient, communicate clearly with funders and partners and keep rebuilding its case has been central to its progress.
For founders, this may be the most transferable lesson. Persistence is not simply refusing to stop. It is continuing to learn. It is testing the story. It is listening carefully when the market responds. It is building enough trust with stakeholders that when something goes wrong, the company still has room to recover.
The Path Is Rarely Linear
Invirsa’s story is a reminder that the entrepreneurial path is rarely linear. Sometimes the breakthrough comes not from the original plan, but from the discipline to keep examining what the evidence is really telling you.
