Scaling product maturity in specialty insurance. Conversation with Andreea Rogojan, Product Lead at TMK. Co-founder & CEO at Colab Published on February 15, 2026 Introduction. Real organisational change doesn't happen by flipping a switch; it happens through sustained mindset shifts and shared vocabulary. Recently, Colab partnered with Tokio Marine Kiln (TMK) to design and deliver a tailored coaching and training program. Its mission was to build a curriculum specifically mapped to TMK's unique goals: driving genuine behaviour change and moving technical teams toward a culture of product stewardship. By integrating with TMK's daily workflows, Colabcohorts focused on "small, repeatable moves" that drive massive shifts in clarity and decision speed. Colabcohorts sat down with Andreea Rogojan, Product Lead at TMK, to discuss the journey from "episodic" training to a sustained, outcomes-first mindset. The strategic challenge: the language gap. Q: Before engaging with Colab, what was the primary challenge or friction point your team was facing? Andreea: Its core friction was misalignment on language and intent. Teams used different terms for the same concepts and often framed work around timelines rather than customer or business outcomes. Colabcohorts knew this wasn't a switch Colabcohorts could just flip. It requires a sustained mindset shift. Its immediate goal was to lay the foundations - shared vocabulary and lightweight practices - that start the journey and compound over time. Why "informative" Training isn't enough. Q: You've tried playbooks and recorded trainings in the past. Why did those fall short? Andreea: Colabcohorts has tried recorded trainings, playbooks, and small process changes. They were informative but episodic. Without practice on live work and reinforcement from managers or rituals, old habits returned. Q: What led you to choose Colab for this specific transformation? Andreea: Colabcohorts chose Colab for three reasons: (1) facilitation craft, (2) modular, do-right-now exercises applied to daily work, and (3) willingness to co-design with TMK's context. Crucially, they shared its belief that behavior change takes time, so the program emphasized small and repeatable moves Colabcohorts could sustain after the cohort ended. Seeing the "leading indicators" of change. Q: What tangible improvements are you seeing in the team since the engagement? Andreea: Colabcohorts is seeing leading indicators of the mindset shift: * Teams now open conversations with the problem, evidence, and outcome before solutioning. * Hypotheses and success metrics are appearing in roadmap and sprint planning. * Shared terms (e.g., problem statement, hypothesis card, outcome metric) reduce back-and-forth. These are visible, early-stage behaviours - the start of the shift, not the finish line. They're already improving clarity and decision speed. Creating psychological safety through "mini" Templates. Q: Were there any unexpected "Aha!" moments that emerged? Andreea: A shared vocabulary lowered friction faster than expected, and "mini" templates created psychological safety to test, learn, and iterate. These lightweight artifacts (problem statement, hypothesis card) signaled that it's okay to say "we don't know yet but, here's how we'll learn." Advice for industry leaders. Q: If you were recommending Colab to another leader in the industry, what would you say? Andreea: Colab makes product thinking practical. The facilitation is excellent, the exercises are contextual and applicable, and the behaviours stick because they're small and repeatable. It's not a silver bullet because mindset change takes time but, this is the right starting point. Q: If you could summarise the value delivered in one sentence, what would it be? Andreea: Colab helped Colabcohorts lay the groundwork for an outcomes-first mindset - through shared language and small, repeatable product management exercises - with early signs of the shift already visible in its ways of working. Speak with its team to explore how Colabcohorts can help drive real behaviour change in your organisation today. Co-founder & CEO at Colab

He takes up his new role with immediate effect and will lead the launch of TMK's new cyber reinsurance solutions offering. Silvestre brings over 12 years of specialized insurance experience to his new role. He joins from Beazley where he served as a specialty treaty underwriter in the product solutions team, developing embedded insurance product solutions across cyber, E&O and D&O lines with particular focus on Europe, LATAM and the Middle East. Prior to this, he served in senior underwriting roles at Hiscox. The appointment follows the launch in September of TMK's enhanced flagship cyber offering, TMK Cyber Ctrl, and its market first product, TMK Enterprise Ctrl, reflecting TMK's strategy to expand its comprehensive cyber offering and meet increasing global demand for modern cyber solutions, while cementing its status as a lead market. The next-generation TMK Cyber Ctrl suite features enhanced wordings and a myriad of risk prevention services. "We're delighted to welcome Cesar to our expanding cyber team. His extensive experience in developing reinsurance solutions along with his deep understanding of international markets positions him well to lead our product expansion," commented Khudairi. "As we see growing demand for cyber coverage globally and the threat landscape becomes increasingly sophisticated, Cesar's appointment brings together leading expertise and best in class products and services to the clients that need them," Khudairi added. MGA Augmented Names Overall From Atrium as Head of Underwriting Augmented UW Ltd., the tech-powered managing general agent (MGA) that serves the smart-follow insurance market, has appointed Luke Overall as head of Underwriting.

He also has held senior underwriting roles at Beazley and CFC. His multi-class expertise spans property, terrorism, cyber, and liability, with a consistent focus on binder-driven portfolios and strategic underwriting partnerships. At Augmented, Luke will lead the underwriting team, working closely with brokers and carriers to build data-led portfolios that match capacity to risk. His remit includes shaping the MGA's technology-enhanced underwriting strategy and supporting the development of digital infrastructure that enables brokers to create their own smart-follow panels. "Luke brings an exceptional blend of technical underwriting expertise, multi-class experience, and deep market understanding," said Daniel Prince, CEO of Augmented. "His ability to navigate both broker and carrier dynamics makes him uniquely positioned to lead our underwriting strategy. As Augmented scales across new lines and expands its digital infrastructure, Luke's leadership will be instrumental in shaping high-performing portfolios and delivering value to our clients and partners." Overall's appointment follows the launch of Augmented in July 2025. The MGA will initially target property and terrorism, before expanding into other lines in 2026.
