3.Build
You get a live preview link early and see the software as it grows. Your feedback goes straight to the engineer.

Built by an engineer who ships his own products
Tacklebear is led by Konstantin Borimechkov. At Tide he scaled invoicing to 100k+ users and built profit-and-loss reporting for more than a million. He was founding engineer at a Y Combinator startup, and today he is a senior engineer in payments infrastructure.
He also builds and runs his own products: Menugram, Vilichki and Codivise. He treats a client project the same way. It has to work, and it has to pay for itself.

Common questions
How much does a website cost?
A custom marketing site costs €600 – €1,200. A site with an admin panel you can edit yourself costs €2,200 – €4,000. Platforms and SaaS products start at €4,000. You get one fixed price in writing before any work starts.
How fast can you deliver?
A website takes 1–2 weeks, a website with an admin panel 2–4 weeks, and a platform two to three months depending on scope. The quote includes a timeline we commit to.
Who actually does the work?
Konstantin, the founder, who is a senior engineer. Nothing is handed to juniors or outsourced without you knowing. You talk to the person who writes the code.
Do I own the site and the code?
Yes. The code, the domain and the accounts are yours. If you ever want to move on, you take everything with you.
Can you add AI to a site or system we already have?
Usually, yes. We start with a two-week pilot on one process, such as answering common customer questions or processing incoming documents. The pilot costs from €900 and gives you a result you can measure before you commit to more.
Can you take online payments on my site?
Yes. Card payments, deposits for bookings, subscriptions and invoicing are a core part of what we build, using Stripe.
