How we work
Agile methodology, direct communication, measurable results
We adapt to your pace and structure so development flows without friction. We focus on early deliveries and continuous improvements so you get real outcomes from the first sprint.
Short, functional sprints
From the first cycle we deliver a working demo. That lets you validate progress, adjust priorities, and stay in full control of the project.
Total transparency
All communication is direct, no middle layers: we speak about code, goals, and results. We document every step so knowledge remains with your team.
True flexibility
We fit into your flowâScrum, Kanban, or a custom setup. We adjust schedules and tools to work as a natural extension of your organisation.
Commitment to milestones
We jump in wherever neededâwhether a single module or the entire productâto help you meet critical deadlines without sacrificing quality.
Visible results from the first sprint
We deliver pieces ready to show leadership, keep technical conversations without intermediaries, and leave documentation your team can reuse.
- Working demo and risk checklist every sprint
- Priorities negotiated directly with technical leads
- Impact metrics and actionable backlog at the end of each cycle
Recognition
Best startup Impulsa Bilbao 2025
Our SareLogic team was awarded Best Entrepreneurial Project at the Demo Day Impulsa Startup 2025 organised by CĂĄmarabilbao.
This recognition showcases our commitment to innovation and highlights the scalability, impact, and technological proposal of the Doctolingo project.
With this award we reinforce our vision of building technology solutions that generate real impact and increase our clients' trust in the quality we deliver.
We are currently advancing Doctolingo as an application for medical students who want to learn gamified, hands-on, and with cutting-edge technology.
Frequently asked questions
Common questions about custom software, automation, and integrations
Before writing a single line of code, we make sure we fully understand the goal and how it will be used. This helps us avoid building âjust to buildâ and focus on a solution that is actually adopted and improves operations.
Iâm not completely sure what the problem is⊠(or I just have an idea). Can you help me shape it?
Yesâand itâs very common. Sometimes you come with an operational pain (âthis is costing us hoursâ), and other times with an idea (âI want a mobile app / a platform / a portalâ). In both cases, we run a short discovery phase to bring order:
- What the real objective is
- Who will use it
- What âsuccessâ would look like
- What the minimum that needs to exist to get started is
From there, we propose the most sensible path: adjust the process, integrate what you already have, or build a custom MVP and validate it as early as possible.
Do I always need custom software, or is it sometimes better to use an existing tool?
Custom is not always worth it. If a standard tool solves the case well and doesnât introduce friction, weâll tell you.
- Custom software is worth it when existing tools donât fit the way you work
- They force constant âworkaroundsâ
- You need integration with your systems to avoid double entry and errors
What exactly is an MVP, and when would I have something usable?
An MVP is the first version you can truly use in real operations and that delivers value, even if it doesnât have âeverything.â
- We design it to start working in operations as early as possible
- To collect real feedback and decide with data what gets built next
- Short iterations: we deliver, you test, and we adjustâno surprises at the end
Can you connect it to my ERP, CRM, Excel, or internal systems?
Yes. Thatâs often where a big part of the ROI comes from: removing manual tasks and the typical copy/paste.
- We integrate via API when available
- If not, we look for secure alternatives (import/export, controlled synchronizations, connectors, etc.)
The priority is that it fits your ecosystem and doesnât create extra work.
Once itâs ready, do you stay on for maintenance, or is that separate?
It depends on what you prefer: we can stay on as your support and evolution team, or hand it over ready for internal ownership.
- Most commonly, we agree on a simple plan (hour packs/bank or a monthly retainer)
- Incidents, small improvements, and ongoing guidance
- And if you donât need anything during a period, we adjust it
The goal is coverage without tying you to something youâre not using.
