Priya Nandakumar
Co-founder & CTO
Ex-Autodesk and Procore. Computer vision on construction documents.
Daniel Okafor
Chief Product Officer
Ex-Bluebeam. A decade building estimating tools.
TE 02 / 07
Co-founder & CEO
Marcus Reyes
Marcus spent fifteen years running preconstruction for a top-25 ENR general contractor, pricing billions of dollars of commercial work across hospitals, data centers, and mixed-use towers. He built and trained the estimating team that turned bid sets into GMP proposals in days instead of weeks, and watched three different "digital transformation" tools fail because none of them understood how a real takeoff gets built: the redlines, the RFIs, the subcontractor quotes that land as PDFs at 11pm the night before a bid is due. After his best estimator quit rather than keep re-keying quantities by hand, he left to build the tool he had wanted his entire career: software that reads construction documents the way an estimator does, not the way a generic AI reads a PDF. He holds a construction management degree from Purdue and is a certified professional estimator. At Plumbline he sets product direction and owns the roadmap for every feature that touches a live bid.

Co-founder & CTO
Priya Nandakumar
Priya spent six years building document-intelligence products at Autodesk and Procore, most recently leading the computer vision team that taught software to read markups, sheet sets, and spec books at the scale of a national GC's document library. From the vendor side she kept hitting the same wall: every construction AI project got scoped as a research problem instead of a workflow problem, because nobody on the team had ever built an estimate under a bid deadline. She met Marcus at an AEC technology conference where he was publicly complaining about exactly that gap, and the two of them were prototyping Plumbline's document-reading engine within a month. She holds a master's degree in computer science from Georgia Tech, focused on document understanding and object detection. At Plumbline she leads engineering and owns the models that turn a stack of drawings into a structured, priceable takeoff.

Chief Product Officer
Daniel Okafor
Daniel spent a decade at Bluebeam building the markup and measurement tools that a generation of estimators learned takeoff on, including four years leading the product team behind Bluebeam's quantity takeoff workflow. He watched estimating software get faster at drawing polygons without getting any smarter about what those polygons meant, and left to build a product that treats a takeoff as structured data from the start instead of a drawing to be manually measured. He joined Marcus and Priya as the third co-founder six months into Plumbline's build, brought in specifically to make sure the product felt like software an estimator would adopt, not a research demo. He holds a civil engineering degree from Georgia Tech. At Plumbline he owns the product roadmap end to end, from the first document upload to the exported bid package.
