The wordmark, with two map-sliders where the letters should be. It looks like a dashboard because that is the point.

Tolemi.
The map that reads city hall's mind - one messy database at a time.
Acity analyst opens one tab. Not twelve. She types an address, and the screen fills with everything the government already knew but could never see in one place - who owns the parcel, what it owes in taxes, which code violations are stacking up, how the block has shifted over five years. This is a Tuesday at a city that runs Tolemi. It used to be a two-week email chain.
Tolemi builds the unglamorous plumbing beneath that moment. Its platform, BuildingBlocks, connects data trapped in different departments, formats, and decades-old systems, then lays it on a single map. Property records meet ownership records meet the assessor's file. The result is not a dashboard for its own sake - it is a way for local governments to find the failing building before it becomes a vacant lot, and to act while there is still something to act on.
A map-based application that connects and continuously updates data across departments and agencies. It mines property and ownership data, runs advanced spatial analysis, and automates reports - so staff find answers in seconds instead of weeks.
A configured build aimed at the housing crisis: preserve and create affordable homes, keep families housed, flag predatory investors buying up blocks, and put publicly-owned real estate to community use.
Run with Accelerator for America, this cohort gives participating cities no-cost access to a custom BuildingBlocks. It was showcased at the Clinton Global Initiative and has reached 17+ cities.
"Tolemi helps governments take a data-driven approach to ensure safe, stable, and affordable housing."
The company began life as OpportunitySpace, co-founded by Andrew Kieve and Nico Tejera. After a stint in Y Combinator, it rebranded to Tolemi - a play on Ptolemy, the Greek polymath who stitched together scattered geographic knowledge into the science of cartography. The name is a thesis: connect what already exists, and you get a clearer map of the world.
Founded in Boston as OpportunitySpace by Andrew Kieve and Nico Tejera.
The mapping platform that becomes BuildingBlocks goes live.
Joins YC's Winter 2017 batch, rebrands to Tolemi, and sharpens its product.
Raises seed funding backed by Lightspeed, Y Combinator, and Fika Ventures.
With Accelerator for America, launches a cohort that reaches 17+ cities and lands at the Clinton Global Initiative.
Stanford (International Relations) and an MBA from IESE. Leads the company's public-sector mission.
Builds the engine that connects municipal systems and turns raw records into a live map.
Tolemi's clients are state and local governments and public-sector agencies. The platform runs in metros as large as New York City and in smaller municipalities like Sherman, Texas; Richmond, California; and Rockford, Illinois. That range is the quiet flex: the same tool that serves a city of millions also works for a town where the entire planning office fits around one table.
The business model is B2G SaaS - governments license BuildingBlocks on a subscription, with configured deployments for housing and land-use work. The competition is partly other govtech and GIS platforms, and partly the oldest incumbent of all: the manual spreadsheet.
