Governed analytics, at near-zero cost

The same answer, for a fraction of the cost — on a terabyte.

Tessallite answers the questions your business repeats every day — in Excel, Power BI, the API and the agent — from a tiny maintained summary instead of re-reading the whole terabyte. On a full terabyte of industry-standard data, that turns hundreds of dollars per thousand runs into a few cents, with the identical answer.

The proof — four everyday business questions SF1000 MEASURED

We asked each question through the live connection the way Excel or Power BI would — first the normal way (raw BigQuery), then with Tessallite — and the two answers came back identical. "Cost per 1,000 runs" uses BigQuery's on-demand price (~$5 per terabyte scanned, 10 MB minimum per query).

Tens of gigabytes the normal way; a few bytes with Tessallite — the same answer, for a fraction of a cent instead of a few hundred dollars per thousand runs. ("Customer type" is the retailer's preferred-customer flag.)

See it at true scale SF1000 MEASURED

The cloud bill and the data each question moves, on a real linear scale — not compressed. Lower is better.

What it costs to ask the same question 1,000 times

Three everyday questions, from a simple one to a heavy one. Red = today (raw BigQuery, each time); green = with Tessallite.

The green bars are a few cents — too small to see beside hundreds of dollars. That is the point.

Data scanned to answer one question

The same three questions, in gigabytes. Red = raw BigQuery; green = with Tessallite.

The green bars are a few kilobytes to a few megabytes — invisible beside 66–155 GB. Same answer, tiny read.

What it is worth to you

• A smaller cloud bill, now. The questions your teams repeat every day read kilobytes instead of tens of gigabytes — hundreds of dollars per thousand runs become a few cents, and the saving recurs on every refresh.
• One answer, everywhere. The same governed definition and the same accelerated result in Excel, Power BI, the API and the agent — one source of truth, not five.
• Nothing to hand-build or babysit. Tessallite suggests and maintains the acceleration from how the business actually queries; nothing silently breaks when the model changes.
• The same answer, always. Every accelerated result is the raw-source result — faster and far cheaper, never a different number.

Your whole question set — 17 questions, all accelerated SF1000 MEASURED

Not one query — the everyday set a commercial, finance or merchandising team actually asks. For each, the data scanned the normal way versus with Tessallite, and the recurring cost at 1,000 runs.

Two reusable governed lists — favourite product categories and key stores by state — are defined on the model so everyone filters on the same definition. The heaviest question in the set still drops from $775 to 41 cents per thousand runs.

How we ran it

The industry's standard test, at full scale. TPC-DS is the benchmark the major data-platform vendors use to prove performance: a complete model of a real retailer — sales, returns, customers, promotions, calendar. We ran it at SF1000: a full terabyte, 2.88 billion sales records, 24 tables, loaded clean.
