AI for preparing a lost-deal review

Short answer

After a lost deal, an AI agent gathers the correspondence and notes for one sales opportunity, separates the client's statements from the salesperson's assumptions and prepares a history with questions for the team for the head of sales. The team draws the conclusions. The agent costs from €3,000 net at Syntalith and, with 60 lost deals a month at 40 minutes each, pays back in 3.3 months.

Statistics

Sales and AI: statistics 2026

3.3 mo.

payback of a €3,000 agent with 60 lost deals a month: €1,396 of work today, €493 with checking and the model. Scenario.

Figures checked: 22 October 2026

The client postponed the project, the salesperson recorded price

A client replies to a services proposal: they are postponing the project because another undertaking has become the priority. Earlier, the salesperson heard a concern about the budget and closed the opportunity with the reason „price”. Both pieces of information matter, but they describe different things. A head of sales who looks only at the CRM field will draw a conclusion about the price list, while the reason may have been a change in the client's plans.

The agent sets the email about postponing the project beside the note from the earlier conversation and shows, for each piece of information, who gave it. It proposes a question for the salesperson: after the proposal was presented, did the client confirm that the budget was the obstacle? The answer „I did not ask” also tells you something, because it shows which explanation the company does not have. Some conversations happen by phone, so the draft shows gaps in the notes and the manager can ask for them to be filled in.

What it costs and when it pays back

Scenario: 60 lost deals a month
Today
60 lost deals × 40 min = 40 h (€1,396)
With the system, a person checks the output in 35% of the time
€489
Model, 2 calls per case, Claude Sonnet 5.5
€5
Cost of one case
€23.27 today, €8.22 with the system
Saving
€903 a month

Payback of €3,000

3.3 months

The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 15,000 input and 1,200 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026. The time covers reading the correspondence and notes of one opportunity and preparing questions for the meeting.

The count covers the work around a case: searching, reading, writing and passing things on. What remains is the time to check the output, 35% of today's work in the scenario. Before the quote we measure both times on 20 to 100 cases the team has already handled, in a €0 test that takes 5 working days.

When the reason field in the CRM is enough

A ready-made CRM helps you organise losses: Dynamics 365 Sales lets you link competitors with opportunities and analyse wins and losses. If salespeople fill in the reason and the competitor reliably, a CRM report is enough. An agent makes sense when the reason field says „price” and the real story sits in emails and notes. If the review shows that a proposal used an out-of-date rate, look separately at quote automation.

What to choose for which review
  • A few lost deals a quarter

    a conversation with the salesperson

    no build

  • Reason and competitor fields filled in reliably

    a report in the CRM

    configuration

  • Dozens of deals, the history in emails and notes

Where to start

The first scope covers one sales team and the deals closed in the last quarter. The manager names the materials used for the review and who may read them. We build this as part of AI agents. For the free process review, a description of one case from recent weeks and the tools it ran through is enough. You do not need to send confidential documents, and you get a written plan within 2 working days.

How we count the payback: CRM in B2B sales

We run the same count for your team in the free process review.

€698

a month for entering 300 CRM updates by hand

Payback: 5.1 mo.

4 minutes per CRM update and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: Claude Sonnet 5.5, about 3,000 + 500 tokens per update, at the ECB rate of 1.1205 USD per euro on 22 October 2026. The extra margin is a scenario: we assume that 1 in 400 updates that get lost today ends in an order, with a margin of €459. In the review we count it on your sales process.

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

Data checked on October 25, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

We select a model for the task and check it on your cases. We run it, tune it and maintain it.

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

Questions

  • How does an AI agent help review a lost deal?

    It gathers the emails, notes and CRM fields of one opportunity, separates the client's words from the team's assumptions and prepares a history with questions for the salesperson for the head of sales.

  • Does the agent establish why the deal was lost?

    No. The agent shows who said what and where information is missing. The team establishes the reason at the meeting and records it in the CRM.

  • How much does such an agent cost?

    At Syntalith from €3,000 net. With 60 lost deals a month at 40 minutes each, the payback is 3.3 months. We agree integrations and maintenance before the quote, and the model costs €5 a month.

  • When is a CRM report enough?

    When salespeople fill in the reason and the competitor reliably. An agent makes sense when the real story sits in emails and notes.

Let's talk

Just write, call or choose a date.

We work fast because we hate corporate cotton wool. We don't have salespeople or managers to keep an eye on managers. You talk immediately to engineers who then build your system. We respect each other's time and yours too.

We will accept 3 more companies by the end of the year.
