"
Working prototype in nine days, in the App Store in twelve weeks. They became part of our team — not a vendor.
PM
Priya Menon
VP Product · PaceFit

They shipped our trading app onboarding in 3 weeks — faster than our internal team estimated for the spec alone.

LP
Liana Park
Product Lead · Vault Bank

Their ML triage model is now baseline-of-care for 240 clinics. Zero downtime in 18 months of operation.

DA
Diego Alvarez
CTO · Mesa Health

Best technical writing I've seen from any vendor. ADRs, runbooks, the works — handover took two hours.

HC
Hannah Cole
Director Eng · Glass Foundry

Forecasting accuracy up 31% in one quarter. They tuned the model on our messy data, not a sanitised demo.

RI
Ravi Iyer
Head of Data · Beacon Retail

Senior engineers who pushed back on our brief — and were right both times. That's worth its weight in retainers.

ML
Mei Lin
COO · Pinecrest Logistics

They rewrote our chatbot in two weeks. Containment up from 41% to 78%. We extended the engagement on day six.

TB
Tomás Becker
VP Eng · NorthStar Travel

Tiny team, gigantic output. The Alexa skill they built for us is still our highest-converting acquisition channel.

ZK
Zara Khan
Founder · Inkwell Studio

Our roadmap had a 14-month vision and an 11-month gap. They closed it in nine without a single all-nighter on either side.

BW
Ben Whitford
Head of Product · Gridline Energy

I've worked with five agencies. None followed up after launch. 1° still messages us when our error rate ticks up.

OF
Olivia Ferreira
CTO · Clearwave Media

Built our recommender, evals, dashboard, on-call — all of it. We could not have hired this team for twice the price.

IA
Idris Ahmed
CEO · Drift Mobility

They turned a 12-week 'discovery' into a 5-day sprint with a working prototype. We never went back to long discoveries.

CR
Camille Roux
COO · Atelier Wellness

Quietly competent. No theatre. The chat agent now writes better tutorial copy than our content team — that's the bar.

NB
Noah Bennett
PM · Hollow Oak Games

First vendor we've engaged that left our codebase cleaner than they found it. That alone earned the next contract.

AV
Asha Verma
CIO · Kalapani Industries

Production AI with eval gates, audit trails, and a calm SRE rotation. Compliance signed off in one meeting.

HL
Hugo Larsen
CTO · Nordfjord Bank

Computer-vision pipeline at 99.4% precision on our edge devices. They wrote it to our latency budget, not theirs.

YS
Yuki Sato
Director · Tatsumi Robotics

They shipped our trading app onboarding in 3 weeks — faster than our internal team estimated for the spec alone.
