Press Echoes (in Romania for the moment)

In 2026, most companies still run legacy software (e.g. old ERP system) as their core software system. But customers and internal distribution and sales teams expect ecommerce speed and instant responses as to stock, price and product alternatives.

Press Echoes (in Romania for the moment): A Topic of Public Interest

Even as almost all office workers use generative AI (like ChatGPT), with the associated security risks, the software their employers run in distribution, production, and sales is largely outdated.

What is the solution?

We have conducted an analysis of companies opportunities and fears regarding AI implementation, along with six technical guides that show that hybrid architecture (AI + classic tech) is the only realistic option for large-scale AI implementation in manufacturing, distribution, and B2B sales.

This `open architecture` approach is illustrated for each technical guide with Google Cloud technologies and the AI Sales platform by OPTI.

Below you can find a preview of each guide. You can subscribe to receive the full technical guides before the public launch and see what an AI implementation in B2B looks like in practice.


Why do companies want AI in 2026?

Self-Correction and Reporting: The system that adapts

Static software does not adapt to market volatility or changing inventory priorities. Hardcoded business rules may become obsolete. Implementing AI brings automated recommendations and self-adaptation, even day by day, with continuous intelligent reporting.

2.5x
Scaling speed

Companies with adaptive AI scale implementations much faster than competitors.

+12%
Growth via A/B

Revenue per online search increases through a culture of continuous A/B experiments.

Daily
Re-training

Google Cloud AI systems (recommendations, chatbots) learn continuously from clicks and quotes.

What fears companies have and how hybrid AI architecture solves them?



The Search Paradox: keywords vs. intent and the utility of chatbots.

The customer searches for “screw hole”, should get what the ERP lists as “self-tapping screw.” The customer searches for “SKU-8521”, yet should not get “SKU-8522.” Hybrid search (a mix of classic lexical search and AI-semantic search) combines the advantages of both and can be robust for business uses. We document 40 applications and assistants (chatbots).

43%
Search usage

Of visitors on a retail site go straight to the search bar.

75%
Risk of loss

B2B buyers switch suppliers if the B2B online (including search) experience is better.

2.5x
Conversion rate

Higher for users who use search vs. browsing through the menu.

-90%
No-result searches

Reduction achieved by implementing the hybrid architecture.

Preview Guide #4

Unified data and avoiding hallucinations

Companies cannot function without quality data. GenAI models will not be reliable if they are not grounded in company data, and hallucinations are unacceptable for data such as price and inventory. Hybrid architecture can solve both problems.

$12.9M
Annual cost

The average cost borne by a US company due to poor data quality.

9 hours
Time lost

Average time employees lose weekly searching for information across different systems.

94%
Avoiding AI hallucinations

94% factual answers in a complex RAG architecture, ~100% via SQL architecture for exact data: price, stock.

15 min
Data latency

Data sync interval cloud - local ERP (with hundreds of thousands of products) into OPTI’s Google Cloud architecture.

Security of data and secrets

AI adoption raises concerns regarding the company data and standards: GDPR, NIS2 and ISO 27001 compliance. A “fortress” architecture can provide by-design safeguards.

70%
Confidential processes

Innovative companies use confidential information and trade secrets.

78%
For AI transparency and audit

IT leaders are concerned about AI "audit trail" and transparency in their company.

+47%
AI-driven attacks

Increase in cyberattacks using AI agents worldwide in 2025.

GDPR/NIS2
EU Data & ISO 27001

Cloud data can be stored in the EU (Frankfurt/Warsaw), OPTI is ISO 27001 certified.

Preview Guide #6

US Market Context

US buyers live on mobile. 50% of B2B search queries happen on smartphones (source).

Meanwhile, SMS is still the highest-visibility channel (often cited near 98% open) - but those interactions rarely land in the system of record without manual logging.

Sales teams are switching email/SMS, CRM, pricing tools, and ERP: ~60% of rep time goes to non-selling work (source).

At the same time, the Retail & Wholesale sector runs ~27% turnover, bleeding organizational knowledge faster than teams can train replacements (source).

ERP modernization does not mean clean rewrites: only ~71% choose SaaS, and the #1 rollout pattern is hybrid at ~37% (source).

Most aren’t seeing enterprise EBIT impact from genAI (source), so the winning architecture is a safe AI layer that wraps current ERP.

Regulatory and customer scrutiny is rising too (source).

Press Echoes (from Romania for the moment): A Topic of Public Interest

The study "AI Architecture for B2B in 2026" opened a necessary conversation about the gap between the speed of employees and the infrastructure of companies.

The Romanian coverage of our analysis by over 15 central (Agerpres, Wall-Street) and specialized (TechRider, ClubITC) publications confirms that the tension between legacy systems (ERP) and new AI technologies is a systemic reality.

Quick Questions

Do I need to replace my current ERP to use AI?

No. Hybrid Architecture means an intelligent middleware layer. It connects to your existing ERP (SAP, Microsoft, Senior, Charisma) via API or read-only access, augmenting it with AI capabilities without disrupting core operations.

What is 'Hybrid Architecture' in B2B sales software?

It is a system that combines the stability of traditional SQL databases (for exact pricing and stock) with the flexibility of Vector Search and LLMs (for understanding natural language user intent and synonyms).

How does AI handle unstructured data like WhatsApp orders?

Using multimodal AI models, the system can 'read' images of handwritten notes or listen to voice messages, extracting product SKUs and quantities to automatically populate ERP orders.

Is my data safe if I use AI in cloud?

Yes, if implemented correctly. You can use a 'fortress' security architecture, such as Virtual Private Clouds (VPC) and strict data residency within the EU, ensuring compliance with GDPR and NIS2 standards.

Why is 2026 considered a critical year for B2B AI?

After 2026, the gap between 'AI-native' new businesses and legacy-software traditional distributors will become insurmountable. Early adopters of hybrid architectures will see market competitivity and efficiency.

What happens if the AI hallucinates?

In a hybrid architecture, this is prevented by RAG (Retrieval-Augmented Generation) and SQL by-design verifications. The AI is technically restricted from inventing numbers; it must retrieve the exact figure from your ERP-originated database before answering.

What is the TLDR (conclusion)?

The technology to bridge the gap between static ERP data and dynamic market demands exists today. Adopting a hybrid architecture allows B2B companies to scale sales operations without discarding their foundational systems.

What technologies and methodologies are involved?

Technologies: Enterprise resource planning, Artificial intelligence, Google Cloud Platform, Middleware, Generative AI
Methodologies: Hybrid Architecture, Legacy System Integration, Multimodal Processing, Retrieval-Augmented Generation (RAG), Data Sovereignty, Operational Automation
