Research design and qualitative studies

Focus-group and interview design in English or French, thematic coding and analysis in NVivo, and a clear findings report.

from €1,800

Data cleaning and analysis

Clean, document and analyse project or survey data (Python, R, SQL, Excel). You get a data dictionary, a short memo with charts and a reproducible script.

Advice on study design, natural-enemy ecology, integrated pest management and DNA metabarcoding protocols for research and conservation projects.

from €800

Looking to volunteer, partner with us, share a tool or fund our work instead? Those are not paid services: please see Get involved.

Prices are in euros, are starting points and depend on scope. We agree a fixed price in writing before work starts. VAT is added where the law requires it. Our services are for organisations, not private consumers.

Who this is for

  • Small and medium NGOs and community organisations
  • Networks and umbrella bodies that support their members
  • Universities and research projects
  • Funders and intermediaries that want independent review or grantee training
  • Social enterprises that need to measure impact

We work on sustainable development, conservation, food systems, environmental health and related fields, in line with our statutes. We decline work outside that mission, and we do not work for political parties or candidates.

How it works

  1. Tell us what you need using the form below or by email.
  2. Short call. A free 30-minute call to understand the problem.
  3. One-page proposal with deliverables, timeline and fixed price, within two working days of the call.
  4. Work and handover. You receive finished documents or files, one round of revisions and a short handover. For projects above €1,000 we ask for 50% on acceptance and 50% on delivery, by bank transfer, on 14-day terms.

Reduced rates for small organisations in Sub-Saharan Africa

Small organisations based in Sub-Saharan Africa receive a reduced rate, about 30% to 40% lower. Ask us when you write.

Our first three clients also receive a 15% founding-client rate. In return we ask for honest feedback, and permission to name you only if you are happy to.

Why SUSTAINEXUS

  • Everything pays for the mission. Our statutes require that income from services supports our non-profit objectives and is reinvested in them. Fees fund free guides, open data and field monitoring. Nothing is paid out as profit to members.
  • We say what we have checked. Our guides cite sources and carry a visible review label. We state clearly what has and has not been independently reviewed.
  • We are new. We do not claim a long client list. We offer clear scope, fixed prices and finished deliverables.
  • Open conflicts, openly handled. Our founder also leads a separate company, IntBioW OÜ, which is a founding member. We do not sell that company's products here or send enquiries to it. See our transparency page.

Who does the work

Work is led by Romuald Tcheutchoua, director of SUSTAINEXUS MTÜ, who works in English and French, remotely and in the field. He successfully completed his PhD (viva passed) at University College London, in Biological Sciences, and holds an MSc in Environmental Health, Ecotoxicology and Risk Assessment from the University of Yaoundé 1.

  • Research and evaluation. Four years of field research with 19 farming communities in Cameroon, including focus groups in French analysed with NVivo, alongside DNA metabarcoding and statistical analysis in R and Python.
  • Grants. Lead proposal writer on a Global Environment Facility grant (agroforestry, REDD+ and climate adaptation) for a Cameroonian NGO; lead applicant on a Conservation Action Research Network grant; co-writer and co-lead on a Rufford Foundation grant.
  • Agricultural finance. Certified in agricultural finance by the Frankfurt School of Finance and Management (loan portfolio management, credit risk, value-chain and digital finance).
  • Publications. Tcheutchoua et al. (2024), a gut-content metabarcoding protocol on protocols.io (DOI 10.17504/protocols.io.eq2lyxzmpgx9/v1); Ngang, Tcheutchoua et al. (2020), Journal of Applied Biosciences 7(4).

What we do not do

  • We do not promise funding, results or deadlines we cannot control.
  • We do not write grant applications for a success fee.
  • We do not take work outside our expertise. We will tell you if someone else is a better fit.
  • We do not share your data. We keep project information confidential.
  • We do not give legal, tax or medical advice.

Questions

Do you work only with non-profits?

No. Non-profits, universities, funders and social enterprises. Reduced rates are for small organisations in Sub-Saharan Africa.

Which currencies can we pay in?

We invoice in euros. If your bank cannot pay in euros, ask us: another currency can be agreed in the proposal, with the exchange rate fixed in writing.

Do you use AI?

We use AI tools to speed up drafting and data cleaning, and we check the work ourselves. We tell you when AI was used and never put your confidential data into a public AI tool.

Who owns the work?

You own the deliverables once they are paid for. We may keep anonymised lessons to improve our free guides, and never your data.

How do I know your guides are reliable?

They cite sources, carry a visible review label and say plainly that they are not yet independently peer-reviewed.

Tell us what you need

Send an enquiry and we will reply by email, usually within two working days. You can also write to admin@sustainexus.dev.

We use these details only to reply to your enquiry and, if we work together, to prepare the agreement. We plan to delete enquiries that do not lead to work within 12 months. This form is not a contract and takes no payment.
