Frequently Asked Questions

Q: Can Ortem Technologies handle large enterprise projects? Yes — our upper engagement range reaches $150,000–$200,000 for complex multi-system integrations. For projects above this range requiring dedicated multi-team delivery, LeewayHertz or a larger SI is the more appropriate partner.

Q: Does LeewayHertz offer fixed-price engagements? LeewayHertz primarily works on time-and-materials engagements. Ortem offers fixed-scope, fixed-price delivery for well-defined projects.

Q: How do I evaluate any AI development partner? Ask for: (1) production case studies with verifiable metrics, (2) direct access to the engineers who will work on your project before signing, (3) code ownership and IP assignment clarity, (4) references from clients 12+ months post-launch to understand long-term code quality.

Implementation Speed Comparison: Real Project Timelines

Speed to delivery is the most frequently cited decision factor for mid-market companies evaluating AI development partners. Here is what typical project timelines look like for comparable scopes across both companies.

Enterprise RAG system (10,000 documents, Slack + CRM integration):

• Ortem Technologies: Discovery 1 week, build 5 weeks, QA/deployment 1 week = 7 weeks to production
• LeewayHertz: Discovery 4–6 weeks, build 12–16 weeks, QA/deployment 2–3 weeks = 18–25 weeks to production

The difference is driven by team size, decision hierarchy, and scope process. At Ortem, the engineer building your system is also the architect making decisions. At LeewayHertz, a project manager mediates between client, solution architect, and delivery team — adding coordination time.

For regulated industries where going live quickly is a competitive advantage, timeline compression is often more valuable than a lower hourly rate.

Code Ownership and Intellectual Property

This distinction is often overlooked during vendor selection but becomes critical at project completion.

Aspect	LeewayHertz	Ortem Technologies
Source code ownership	Client-owned, transferred at completion	Client-owned, transferred at every sprint
IP assignment	Standard IP assignment in contract	Full IP assignment + no-use guarantee
Proprietary platform dependency	ZBrain platform creates soft lock-in	100% open-source stack, no lock-in
Codebase access during development	Git repo access provided	Direct repo access from day one
After engagement ends	Transition documentation provided	Complete handoff including runbooks

If you use LeewayHertz's ZBrain orchestration platform for your AI agent, your system has a dependency on their proprietary software. When that contract ends, migrating off ZBrain is a significant engineering effort. Ortem builds exclusively on open-source infrastructure (LangGraph, LlamaIndex, FastAPI, PostgreSQL) — every dependency is auditable, forkable, and has no vendor risk.

Quality Signals: What to Look For in Any AI Development Partner

Use this checklist regardless of which company you choose:

Pre-engagement:

• Can you speak directly with the engineers who will work on your project before signing? (Ortem: yes. Large agencies: usually no.)
• Are case studies accompanied by verifiable outcomes (named clients, specific metrics, dates)?
• Is the discovery phase paid and documented with deliverables?

During engagement:

• Daily or every-other-day async update (not weekly status reports)
• Code review history visible in shared Git repo
• Automated testing coverage reported per sprint
• Architecture Decision Records (ADRs) documenting why technical choices were made

Post-delivery:

• Production monitoring setup (not just "we built it and handed it over")
• Runbook for common operational scenarios
• Defined handoff process if you want to move to an in-house team

When Size Actually Matters: Capacity and Concurrent Workstreams

LeewayHertz's scale (1,000+ engineers) provides genuine advantages for specific scenarios:

Simultaneous multi-workstream delivery: A Fortune 500 running 5 AI programs in parallel (customer service AI, demand forecasting, document processing, predictive maintenance, and internal copilot) benefits from a large agency that can staff all five streams independently without resource contention.

24/7 follow-the-sun development: For projects with hard deadlines, LeewayHertz's US + UK + India presence allows continuous development across time zones. This is genuine capacity leverage that small teams cannot replicate.

Regulatory compliance infrastructure: Large enterprises going through SOC 2 Type II, ISO 27001, or FedRAMP certification processes benefit from vendors who have already been through those audits and can provide documentation packages that expedite your own compliance process.

Ortem Technologies does not compete on volume delivery or 24/7 follow-the-sun development. We compete on senior engineering quality, delivery speed for well-defined projects, and total cost of ownership for mid-market AI implementations.

The Due Diligence Conversation You Should Have With Both Companies

Before signing any AI development contract, run this conversation with every vendor you evaluate:

1. "Show me a production deployment, not a staging environment." Any serious AI agency can give you read-only access to a production monitoring dashboard from a completed project (with client permission). Seeing real query volumes, real latency, and real error rates tells you more than any demo.

2. "What is the worst project you delivered and what did you learn from it?" This question reveals professional maturity. Companies that say every project was successful are not telling the truth. Companies that give a specific, detailed answer with concrete changes they made afterward have learned from failure.

3. "What does your offboarding process look like?" The best development partner actively prepares you for the day you no longer need them — whether that means building an internal team, transitioning to a different vendor, or running the system with minimal ongoing support. Any company that is vague about this question has not thought through your long-term success.

4. "What AI models will you use, and what happens if those models are deprecated?" Model obsolescence is a real risk in enterprise AI — GPT-4 is being sunset, specific API versions change. Ask for the model versioning strategy and the upgrade plan.

Frequently Asked Questions: Advanced

Q: Does Ortem Technologies work with clients who already have a LeewayHertz engagement in flight? Yes — we have done technical due diligence reviews for clients mid-engagement who had concerns about delivery quality, and we have taken over projects at various stages of completion. This is delicate work that requires careful codebase assessment and clear communication with all parties.

Q: Can LeewayHertz's ZBrain handle custom LLM integrations? ZBrain is primarily optimized for OpenAI and Anthropic models. Custom fine-tuned models or alternative providers (Mistral, Llama, Cohere) require additional integration work that sits outside ZBrain's standard capabilities.

Q: What is the realistic engagement cost with each company for a 3-month AI project? A 3-month engagement with a team of 4 engineers:

• LeewayHertz: $120,000–$200,000+ depending on team seniority and project complexity
• Ortem Technologies: $45,000–$85,000 for equivalent engineering quality and output

Q: Is there a project scope where Ortem Technologies would recommend LeewayHertz instead? Yes. If your project is a $1M+ enterprise AI transformation requiring 10+ concurrent engineers, executive-level engagement management, and enterprise procurement compliance (long MSA negotiations, security audits, SOC 2 documentation packages), LeewayHertz is the better partner. We are honest about the ceiling of what a focused senior team can deliver at our engagement size.

Contract Types and Payment Structures

Understanding how each company structures engagements protects you from scope creep and unexpected costs.

LeewayHertz contract types: Most engagements are time-and-materials (T&M) billed at $75–$150/hour depending on seniority. Fixed-price projects are rare and typically limited to well-defined deliverables with extensive discovery phases. T&M protects the agency; fixed-price protects the client — understand which you are signing.

Ortem Technologies contract types: Fixed-scope, fixed-price for projects where requirements can be defined clearly. Time-and-materials for ongoing retainers and maintenance. We prefer fixed-price because it aligns incentives: we are not paid to take longer. Clients get budget certainty; we have incentive to scope accurately.

What to verify before signing any AI development contract:

• Who handles overruns if the project scope grows? (Client pays all overruns in T&M; fixed-price shifts this to the agency for in-scope work)
• What is the change request process? (How are out-of-scope requests priced and approved?)
• What triggers penalties or credits? (Missed milestones, quality defects, delayed feedback from client side)
• Who owns the models if fine-tuned models are part of the deliverable?
