Valentine’s primary business is logistics. Once he had an idea on organizing a back-office and inventory management. The only thing left was for sales to kick in.


Rapid prototyping

So in just 3 months time GRIN tech prototyped an online store for him.


Feedback & data mining

We parsed competitors' pricing to maximise revenue and see whether we are up to the market. Positive marketing ROI since first month.



Our initial proposal for UX and website structure was accepted and paid off. The second month due to site functionality and data enrichment 80% of site pages were listed on Google and generating first sales


Custom CRM

To cut initial costs all orders were handled in Google sheet. Later on we made a custom CRM: SMS\email notifications on status updates, analytics etc.


Research, planning & prototyping

Deliverable: functional specification.


Roadmap & budget breakdown

Transparent pricing. Strategy proposal for 6 month ahead.



Deliverable: project shipped to production. Pixel perfect front-end, bullet-proof back-end.


Ongoing support

Only pay once. Bugs and rare cases at our expense.

Changelog – pre-ecosystem era

v0.1.8 Hound @ – b2b prospecting platform

v0.1.8.1 Business directory – content experiment to support b2b prospecting platform.

v0.1.6 GRIN tech affiliate program is live.

v0.1.5.2 Working on cool in-house lead gen project - Art Director is preparing 100 picks of Business Cards in various niches.

v0.1.5.1 GRIN games emerged

As a web agency we never could and never will be able to escape the urge of building things.
Among million other things we played with an idea of text-based games and the last piece that was missing was the story itself. So via in-house outreach platform we found two established writers that believed in the project and agreed to participate.

Shout out to Richard Abbott who wrote Fraud on Thetis and Eva Pohler who sent us a huge draft we are still reading through.

v0.1.4 GRIN launcher is born.
It is an outreach platform that we use to establish connections with editorial teams.
They say samples of published articles look good but pricing looks even better

At some point we realised that list building, fetching contact details & outreach tech work just as well for b2b lead generation

v0.1.3 Once, we fell in love with ecommerce, because of short feedback cycles on marketing & development efforts.
Today we ship into production inhouse SaaS project - AVOKADO - the web app for learning languages with flash cards.

The year after we built it we realised how long is the road map ahead & what resources we'd need to promote it and decided to put it on hold.

One day as we ship GRIN tech v3.0 into production we'll distrupt the language learning market with Avokado.

We love Wordpress and recently shipped two plugins into open beta for commercial sale.

v0.1.2.2 King The Monk - wordpress plugin to virally grow your email list

v0.1.2.1 Plain Conversions - wordpress plugin to convert your visitors

v0.1.1. Expanded core offering to visual productions
