Combinely joins Y Combinator X25

Combinely has been accepted into Y Combinator's X25 batch. This milestone validates something we have believed from day one: AI can fundamentally transform how tax professionals work, but only if it is built alongside the people who use it.

Built in Practice

We spent months embedded inside firms, working side-by-side with tax professionals to understand real workflows. Not observing from a distance. Not running surveys. Sitting in the trenches, watching pain points unfold in real time. That immersion shaped Combinely as it exists today, now live firm-wide at our first major client. The feedback has been direct: "You saved me 4 hours last night." "I'm never sending out a tax return unless I've used Combinely."

What Comes Next

As part of this next chapter, we are relocating to San Francisco and joining the YC community. Being close to other founders, moving faster through tight feedback loops, and accessing the Bay Area talent pool matters at this stage. We are focused on expanding Combinely to more tax firms and pushing what is possible at the intersection of AI and tax workflows.
