Chair, Halyard
First there was Excel, then there was Sheets, now there's Tessera. Built by part of the early @halyard crew. Genuinely proud of them.
Tessera is the only spreadsheet with live connections to your warehouse, full version history, and real-time editing.

It is roughly ten times faster to build and automate an analysis on native connections — cohort reports, funnel reviews, board decks and everything between.
Every shortcut and formula you already use still works. If you can drive Excel or Sheets, you can drive Tessera on day one.
Every change is saved with a name and a timestamp, so anyone can see how a number came to be. Show your work without trying.
Founders and operators love Tessera.

Patrick NightingaleVery neat!
Naomi BrightPulling the data can be half the daily battle, and most of what's left goes into shaping it for analysis. Then the next month you rinse and repeat the whole painful thing. With Tessera you automate the slowest parts and spend the hours on the actual question.
Tomas BerglundIf you have ever tried to bridge the gap between the analysts who live in the warehouse and the operators who live in a grid, this is the first honest answer I've seen. @usetessera nailed the handoff.
Ines DuarteTwo of our recurring reports now rebuild themselves overnight. I have stopped dreading the first Monday of the month.
Miles Okafortessera.app = sql + sheets, finally in the same window. One of two data tools I've been genuinely excited about since Kinetiq shipped.
What would a spreadsheet look like if you designed it this year? It would sit on top of the source data instead of asking you to copy and paste. Glad to be leading the seed for Tessera. Congratulations @daraw @usetessera!
Owen TraskReally a good product. We've had it at Plume for about six weeks and it changed the shape of the week, because we always end up back in a grid anyway. The reliability of the connections to our internal systems is the part that surprised me.
Delia VanceSuper excited for @usetessera. We'll see a lot of Excel power users switching over in the next year.
Rhea CastellanosIn the world of analysis tooling, this is like @thefoundry deciding to make their own bench. @usetessera clearly understands the job. Curious to see what lands next.
Anders EklundAs an early user of Tessera I can confirm it gives you one of the shortest routes from raw warehouse data to the exact number you were after, whether or not you write SQL. Looking forward to what's next.
Yusuf AdeyemiSo many consequential decisions rest on analyses that live in a spreadsheet. The money attached to those decisions is enormous, so think about what the underlying tool is worth. @usetessera is finally modernising it.
This tool solves so much friction and PTSD every analyst has ever faced trying to analyse live production data.
Teo MarchettiI just started using it and I already love the integration with Frostline. What used to be a two hour Monday morning ritual is now automated and, honestly, it makes it so much easier.
Harriet NwosuBear with the team at Tessera — they ship fixes faster than we can file them.
“Our primary growth dashboard is built in Tessera. With 147 metrics on it, you really do want a spreadsheet surface fed by several sources and models. We also need it to refresh itself. Tessera gives us all of that in one place, sharing is trivial, and it is genuinely easy to set up and iterate on.”
