For hardware teams without an FEA seat

"We're about to spend $40K on tooling and I still don't know if the bracket holds"

Yusuf ran the FEA in 18 hours

Load cases, mesh convergence, safety factors — a signed calc sheet and memo, back as .xlsx and PDF.

For product teams shipping AI without an ML hire

"We're shipping an AI feature next quarter and nobody on the team has trained a model."

Cuauhtémoc fine-tuned and benchmarked the model in 36 hours

Weights, code, and an eval report — accuracy and hallucination rate against your current baseline.

For R&D leads and technical diligence teams

"The investment memo is due Friday and I can't cite a chatbot summary."

Kar Wey synthesized 28 sources in 24 hours

A sourced technical brief — every claim cross-checked, citations formatted, ready to cite.

For technical founders on the hook for the numbers

"I think the numbers are right. I'm not putting this in front of the board until someone else has looked."

Alexander re-derived the model same-day

Math re-derived, code re-run in Python, errors flagged inline — confirmed before the meeting.

What people say

Allison

Founder, EdTech

AI got us 85% of the way on the modeling — having a real physicist verify the last 15% is exactly what we needed.

Roman

Hardware founder

We were going to hire a senior engineer for a one-off calc. Tendem did it overnight, verified, for a fraction of the cost.

Yana

Director of a Biotech Lab

Pure AI correctly identifies the vendor, but makes errors in amounts (3–5% error rate)… zero error tolerance. Unlike other AI platforms, Tendem is great for such tasks!

Pavel

Product Manager, Fintech

We used Tendem for labeling German invoices to train our OCR model. The data labeling quality was excellent.

Lada

Senior Designer

…everything was verified and compared thoroughly… validated by a human. Saved me two days of work.
