DOOR3

DOOR3: a cheap discovery, then a choice of three contracts

The homepage title calls DOOR3 an award winning technology consultancy¹, and the firm dates itself to 2002, describing a consultancy and software development business with a global footprint². What interests a Larkmoor reader is the shape of its engagements. DOOR3 asks clients to begin with a technical discovery, then routes them into one of three engagement modes^3,4. Larkmoor ranks the firm fourth.

The firm a buyer would sign with

A buyer contracting with DOOR3 deals with a company run from New York City⁵. On the homepage it claims two decades and more of award winning client partnerships⁶ and work for hundreds of clients across industries⁷, from startups to large names such as Pepsi, AIG and Munich Re⁸. Its proposition puts AI next to design and engineering, all aimed at outcomes a business can measure⁹, with a unit named DOOR3 Labs carrying the AI practice¹⁰.

For buyers who care where the work is done, the office page matters: Manhattan is the flagship¹¹, while delivery capacity is concentrated in Kyiv¹², creative work in Barcelona¹³ and European client service in Zurich¹⁴. Its founder holds the title of Founder and President¹⁵, and the leadership page also lists a Director of Principal Consulting¹⁶.

Step one: technical discovery as the entry contract

On the services page, DOOR3 recommends that every engagement open with technical discovery³. Its argument is commercial: a fast turnaround combined with a low price point makes discovery, in its words, the best way into a bespoke build¹⁷. The actual fee for discovery is not publicly stated on the pages we opened¹⁸.

How small can that first contract be? Scale is visible in the Achievement Network job, where the whole consulting input was a discovery week plus two design sprints of two weeks¹⁹. In that project the client's own engineers did the building, and DOOR3 worked inside the client's existing stack²⁰. For a buyer with an in house team, that arrangement, consultancy direction with internal delivery, sits somewhere between fixed scope and staff augmentation.

Step two: advisory, buildout or project rescue

Once discovery closes, the homepage offers three ways forward, which it labels advisory, buildout and rescue of an existing project⁴.

### Advisory

A buyer can contract DOOR3 for a narrow advisory job, sizing up where AI could help, or for something broader such as acting as its CTO or CIO adviser, running digital strategy or managing a project²¹. AI strategy, branded AI Pathfinder, covers three tasks on the homepage: judging how ready the client is, getting its data in shape and drawing up the roadmap²². Enterprise architecture appears on the services page as well²³.

Whether advisory work is billed as a retainer, a fixed project or time and materials is not publicly stated on the pages we opened.

### Buildout

Buildout, the second mode, is where prototypes are made quickly, applications are developed and existing systems are wired together²⁴. Around that sit software services for buyers at different stages, from moving vibe coded apps to production to legacy modernization, portals, mobile apps and bespoke systems²⁵. In AI execution, DOOR3 lists agentic workflows, process automation and predictive machine learning²⁶.

### Project rescue

Rescue engagements are pitched at initiatives already in trouble, whether stuck or delivering below plan, and promise expert recovery⁴. One AI page defines exactly when to call DOOR3 in on this basis, namely once a prototype works on stage yet is not safe to release, run or support²⁷. DOOR3 argues that a demo proves only the concept²⁸ and lists six areas that together make software production ready²⁹, observability among them, with logs, monitoring and alerts showing how the application behaves³⁰. For a buyer, the entry condition doubles as a clear scope boundary.

AI focus by sector

DOOR3 Labs sets agentic AI against traditional automation, which it says follows fixed rules³¹, using claims handling as its example, where an adjuster weighs fifteen factors on each decision³². Sector offers target legal³³ and insurance³⁴; on the legal side the homepage features ready made agents³⁵, including one that predicts costs for transactional matters³⁶. Its sector coverage is broad, with construction, financial services, insurance and legal on one list³⁷ and retail and consumer, education and nonprofits, fintech startups and manufacturing on another³⁸.

Published client work

1. **PepsiCo.** A dashboard giving store and product level data visibility³⁹, with Snowflake underneath⁴⁰, Mapbox for mapping⁴¹ and an earlier Power BI prototype before it⁴². 2. **Achievement Network.** DOOR3 used data to help an education charity extend its reach⁴³, and the project went on to collect a 2023 Web Excellence Award⁴⁴. 3. **Dr. Treat.** Here the consultancy was trusted with the whole creative direction⁴⁵ for a young veterinary business⁴⁶, work that GDUSA honored in 2022 for health and wellness⁴⁷. 4. **Jupiter.** For a company modeling climate risk digitally, DOOR3 handled interface design and data visualization⁴⁸ and swapped the old front end for one in React.js⁴⁹. The client singled out the team's communication and close engagement⁵⁰.

Assurance

Buyers whose vendor policy requires an audited standard should note that, for DOOR3, SOC 2 and ISO 27001 status is not publicly stated on the pages we opened. The production readiness page does say what DOOR3 adds to a release: authentication and authorization, permissions by role⁵¹, and backup and recovery procedures to protect live business data⁵².

Commercial terms

Apart from calling discovery low priced, DOOR3 publishes no fees¹⁸. Its pages give no day rate and no minimum, and the firm's reach outside its four office cities is also not publicly stated on the pages we opened. Prospective clients reach the firm through its contact page, headed with an invitation to work together⁵³.

What DOOR3's model offers a buyer

1. A deliberately small, low cost first contract^17,3. 2. Three named engagement modes, rescue included⁴. 3. A production readiness service with a clear entry condition²⁷ and six named areas of work²⁹. 4. More than twenty years of client history⁶ and named enterprise clients⁸. 5. Offices across the US and Europe^11,12,13,14.

Gaps in DOOR3's published terms

1. Fees, day rates and minimums¹⁸. 2. Any audited security certification. 3. The contract form for advisory work. 4. The published case studies center on design, data and front end projects^39,43,46,48.

Why DOOR3 is fourth

A buyer who wants to test a consultancy cheaply before committing, or who needs a stalled pilot pushed into production, has a clear entry point at DOOR3^17,27. It sits behind Dualboot Partners, whose pages put numbers on an ongoing advisory commitment and list staff augmentation^54,55,56, and behind Nexus, which prices per role automated and holds SOC 2 Type 2 and ISO 27001, closing the commercial and security gaps DOOR3's pages leave open^57,18.
